3 Log #100 Bob Eugene, Underwriters Laboratories Inc UL Publications Underwriters Laboratories Inc., 333 Pfingsten Road, Northbrook, IL ANSI/UL 21, Standard for LP-Gas Hose, ANSI/UL 94, Standard for Safety Test for Flammability of Plastic Materials for Parts in Devices and Appliances, , revised ANSI/UL 125, Standard for Valves for Anhydrous Ammonia and LP-Gas (Other than Safety Relief), ANSI/UL 144, Standard for LP-Gas Regulators, , revised ANSI/UL 181, Standard for Safety Factory-Made Air Ducts and Air Connectors, 2005, revised ANSI/UL 217, Standard for Single and Multiple Station Smoke Alarms, , revised UL 330, Standard for Hose and Hose Assemblies for Dispensing Flammable Liquids, ANSI/UL 484, Standard for Room Air Conditioners, , revised ANSI/UL 569, Standard for Pigtails and Flexible Hose Connectors for LP-Gas, ANSI/UL 842, Standard for Valves for Flammable Liquids, ANSI/UL 1484, Standard for Residential Gas Detectors, , revised ANSI/UL 2034, Standard for Single and Multiple Station Carbon Monoxide Detectors, , revised ANSI/UL 2061, Standard for Adapters and Cylinder Connection Devices for Portable LP-Gas Cylinder Assemblies, Update standards titles to indicate ANSI approvals and revision dates. The Committee agrees with the intent to have the most up to date ANSI edition of the Standards, but only one ANSI date should be referenced to eliminate any confusion. The submitter is encouraged to submit a public comment with only the most current ANSI edition date referenced for each Standard. The Committee also requests more information regarding the need for revision dates. The Committee is confused regarding the retroactive dates, such as UL Log #121 Jeff Wisniewski, MTI Industries, Inc. UL 217, Standard for Single and Multiple Station Smoke Alarms, UL 217 was re-published in October Keeps NFPA 1192 current with latest UL revision Log #122 Jeff Wisniewski, MTI Industries, Inc. UL 1484, Standard for Single and Multiple Station Smoke Alarms, UL 1484 was re-published in October Keeps NFPA 1192 current with latest UL revision. Revise proposal as follows: UL 1484, Standard for Single and Multiple Station Smoke Alarms Residential Gas Detectors, Editorial correction. 2

4 Log #9 Add new definitions as follows: Combustible- Any material having a flame spread index of higher than 25 when tested in accordance with NFPA 255. Noncombustible- Any material having a flame spread index of 25 or lower when tested according to NFPA 255. These two terms are used in the following sections of the standard: , , , table, 5.7.5, These terms need to be defined in the standard. The Committee agrees with the submitter's intent to delineate between combustible and noncombustible materials but does not agree with the use of a flame spread index where fire protection is needed. Further NFPA 255 has been withdrawn and other references should be cited Log #10 Add the following new definition: Fixed Maximum Liquid Level Gauge- A fixed liquid level gauge that indicates the liquid level at which the container is filled to its maximum permitted filling limit. This definition from NFPA 58 should be in the 1192 standard, since it is referenced in Extract from NFPA 58, 2008 edition, Section Log #11 Add New Definition: Hose. A flexible tube for conveying a liquid or gas. The term hose is used within NFPA 1192 and therefore requires a respective definition. This definition came from Websters Dictionary. 3

5 Log #CP6 Technical Committee on Recreational Vehicles, Change existing language definition of to read : Compartment. Within a recreational vehicle, an enclosed volumetric space designed to provide for a separate area. The definition needs to be more encompassing for industry recognized areas that may involve areas not confined on all six sides. NFPA Glossary of terms defines an enclosed compartment as, An area designed to protect stored items from environmental damage (weather resistant) that is confined on six sides and equipped with an access opening(s) that can be closed and latched. The new language will further clarify the intent of the word compartment to involve all areas of the coach. This proposal is being rejected, and is intended to serve as a place holder so public comments can be submitted Log #120 Glossary of Terms Technical Advisory Committee, Readily Accessible. For recreational vehicles, able to be located, reached, serviced, or removed without removing other components or parts of the apparatus and without the need to use special tools to open enclosures. It is important to have consistent definitions of terms within NFPA. The term readily accessible at present has several definitions. The preferred one is in NFPA 70 and it reads as follows: Readily Accessible. Capable of being reached quickly for operation, renewal, or inspections, without requiring those to whom ready access is required to climb over or remove obstacles or to resort to portable ladders. The one in NFPA 1192 is different from it but suitable for the document. It is recommended that it be retained. I am the chairman of the NFPA Advisory Committee on the Glossary on Terminology. The committee was created by NFPA Standards Council to provide consistency in terminology throughout the NFPA documents. 4

6 Log #12 Delete the current definition of Recreational Vehicle (RV) as shown below and replace with the following: * Recreational Vehicle (RV). A vehicular-type unit primarily designed to provide temporary living quarters for recreational,camping, travel, or seasonal use that either has its own motive power or is mounted on or towed by another vehicle. A Recreational Vehicle or RV is a vehicular type unit that : (i) is primarily designed as temporary living quarters for recreational and/or camping use; (ii) has its own motive power or is mounted on or towed by another vehicle; (iii) is regulated by the National Highway Traffic Safety Administration as a vehicle or vehicle equipment; (iv) does not require a special highway use permit for operation on the highways; and (v) an individual can easily transport and set-up on a daily basis. The basic product types are: Motorhome and Non-Motorized RV. The proposed, revised definition of recreational vehicles adds criteria to better delineate recreational vehicles (RV) from other types of manufactured structures and helps by establishing criteria to ensure that RVs are vehicles as defined by the National Highway Traffic Safety Administration (NHTSA). The language that is generic and applicable to all RVs had been moved to this proposed base definition of RV, so the individual entity definitions that will appear in the appendix can be streamlined for additional clarity. Note: Supporting material is available for review at NFPA Headquarters Log #62 Ryan A. Lehman, Newmar Corp. Revise text as follows: For recreational vehicles, a grade or fall of a line of pipe in reference to a horizontal plane and expressed in units vertical per units horizontal. Identification of slope as a ratio provides clarification on how slope is quantified. See and References: International Residential Code (IRC), 2009; International Building Code (IBC), 2009; 24 CFR Part (HUD) Standard. The Committee does not believe that the proposed language provides any benefit to the 5

7 Log #13 A fitting or valve device designed and constructed to provide a liquid or mechanical seal that will prevent the back passage of air without materially affecting the flow of liquid waste through it. As is currently written the standard does not allow for new technology. There now is a listed plumbing component that can be used as an alternative to a water seal trap. The standard should be written broad enough to allow either a water seal trap or a different type of device that may not use a water seal. Defining and differentiating between a trap that uses a water seal and a trap that does not would resolve the issue within the standard Log #14. That portion of a fixture drain between a water seal trap and its vent. This proposal is related to proposals on and This clarifies this requirement applies to water seal traps only not other types of devices that qualify as traps but do not depend on a water seal, such as a waterless waste valve. As is currently written the standard does not allow for new technology. There now is a listed plumbing component that can be used as an alternative to a water seal trap. The standard should be written broad enough to allow either a water seal trap or a different type of device that may not use a water seal. Defining and differentiating between a trap that uses a water seal and a trap that does not would resolve the issue within the standard Log #15. The vertical depth of liquid that a water seal trap will retain.

Defining and differentiating between a trap that uses a water seal and a trap that does not would resolve the issue within the standard Log #17 Change the language as follows: Propane piping and hose located less than 4 ½ in. (114 mm) from the exhaust system, the transmission, or a heat-producing component of an internal combustion engine or hydronic heating appliance shall be shielded by a vehicle frame member or by a noncombustible baffle with an air space on both sides of the frame member or baffle. This language makes the requirement consistent with the similar requirement in Revise Section and the proposed language in as follows: Propane containers located less than 18 in. (457 mm) from the exhaust system, the transmission, or a heat-producing component of a combustion engine or hydronic heating appliance exhaust shall be shielded by a vehicle frame member or by a noncombustible baffle with an air space on both sides of the frame member or baffle Propane piping and hose located less than 4 ½ in.

(3) The mating connection to the cylinder valve shall be provided with a CGA 791 female connection that does not attach to a CGA 510 female POL connector. Update standards titles to indicate ANSI approvals. 8

10 Log #105 Bob Eugene, Underwriters Laboratories Inc A separate first stage of a two-stage regulator system shall incorporate an integral pressure relief valve having a start-to-discharge setting within the limits specified in ANSI/UL 144. Update standards titles to indicate ANSI approvals Log #106 Bob Eugene, Underwriters Laboratories Inc The second stage of a two-stage regulator system shall be equipped with one or both of the following: (1) An integral pressure relief valve on the outlet pressure side having a start-to-discharge pressure setting with the limits specified in ANSI/UL 144 and shall limit the outlet gauge pressure of the second stage of a two-stage regulator system to 2.0 psi (14 kpa) when the regulator seat disc is removed and the inlet gauge pressure to the regulator is 10.0 psi (69 kpa) or less as specified in ANSI/UL 144. (2) An integral overpressure shutoff device that shuts off the flow of propane vapor when the outlet pressure of the regulator reaches the overpressure limits specified in ANSI/UL 144 and shall not open to permit flow of propane until it has been manually reset. Update standards titles to indicate ANSI approvals Log #CP5 Technical Committee on Recreational Vehicles, Revise (2) to read as follows: The high-pressure propane system shall be located entirely on the exterior of the vehicle or in a compartment that is vaportight vapor resistant to the vehicle's interior. The Technical Committee revised (2) to maintain consistency in terminology throughout the Standard. 9

11 Log #18 Change language as shown: Tubing or hose shall not be run inside walls, floors, partitions, or ceilings. Where tubing or hose passes through walls, floors, partitions, roofs, or similar installations, such tubing or hose shall be protected by the use of weather-resistant grommets that fit snugly both the tubing or hose and the hole through which the tubing or hose passes. Tubing and hose shall be routed to be protected from physical damage, sharp edges, and moving parts. Unprotected tubing or hose shall not be located in storage areas. These requirements for protection of tubing are expanded to include hose. Listed flexible assemblies are often a part of the propane system in RVs, and should be subject to the same protection requirements as tubing. Revise proposal as follows: Tubing or hose shall not be run inside walls, floors, partitions, or ceilings. Where tubing or hose passes through walls, floors, partitions, roofs, or similar installations, such tubing or hose shall be protected by the use of weather-resistant grommets that fit snugly both the tubing or hose and the hole through which the tubing or hose passes. Tubing and hose shall be routed to be protected from physical damage, sharp edges, and moving parts. Unprotected tubing or hose shall not be located in storage areas. Where nonmetallic tubing or hose is used within the propane piping system, it shall be permitted to pass directly through any floor, wall, partition, or ceiling, provided the entire length of hose is readily available for visual inspection, provision is made to protect against chafing, and no part of the flexible nonmetallic tubing or hose is concealed in the hollow space of a floor, wall, partition, or ceiling. Flexible Nonmetallic Tubing and Hose Connections Where nonmetallic tubing or hose is used within the propane piping system, it shall be permitted to pass directly through any floor, wall, partition, or ceiling, provided the entire length of hose is readily available for visual inspection, provision is made to protect against chafing, and no part of the flexible nonmetallic tubing or hose is concealed in the hollow space of a floor, wall, partition, or ceiling Flexible nonmetallic tubing or hose shall not be permitted to enter the burner box of the range or cooktop as the final connection. The revised proposal recognizes the use of hose and moved routing and protection requirement from to for clarification Log #107 Bob Eugene, Underwriters Laboratories Inc Propane supply connectors used in propane systems shall be listed as an assembly using ANSI/UL 569 or ANSI/UL 21 hose. Update standards titles to indicate ANSI approvals. 10

12 Log #19 Change language as shown: All piping shall be anchored within 6 in. (152 mm) of tubing or hose connections, at the end of piping runs All piping shall be anchored within 12 in. (305 mm) of tubing or hose connections within piping runs. This requirement should also cover the anchoring of hose connections to either tubing or pipe within the propane system. Flexible hose assemblies are used for galley slideout room applications within RVs Log #20 Change language of (a) as follows: (a) The source of the air pressure to the piping system shall be shut off. The entire system shall be pressurized to not less than 3 psi (20.7 kpa), and the system then shall be isolated from all sources of pressure. This language is consistent with (1)(a) and better states the correct procedure Log #21 Change language as shown: (3) As an alternative test, the appliance and regulator connections not tested in shall be tested for leakage with either soapy water or a bubble solution. Editorial. Revise proposal as follows: (3) As an alternative to the pressure drop test, the appliance and regulator connections not tested in shall be tested for leakage in accordance with with using either soapy water or a bubble solution. Clarifies the intent of the requirement to ensure that the final connections are leak tested. 11

13 Log #CP3 Technical Committee on Recreational Vehicles, Revise Section and add a new as follows: The regulated high pressure piping systems, except those constructed only of listed hose assemblies and not including regulators, shall be proven by test to be leak free by maintaining an air pressure of at least 45psi (310.5 kpa) for a period of at least 10 minutes. Before the test is begun, the temperature of the air and of the piping shall be approximately the same, and a uniform temperature shall be maintained throughout the test period. Leaks, if observed, shall be located and corrected. Defective material shall be replaced. Products that contain ammonia or chlorine shall not be used for testing. Tests shall be conducted by the following method: (a) The source of the air pressure to the piping system shall be shut off. (b) The pressure in the system shall be measured over a period of 10 minutes with a device, calibrated so as to be read in increments of not greater than 2 psi (14 kpa). (c) During the 10-minute period a drop in pressure shall not occur. After the piping system regulators, related fittings and connections are installed in the RV the entire regulated high-pressure piping system shall be proven by test to be leak-free by maintaining an air pressure of not less than 15 nor more than 30 psi. Before the test is begun, the temperature of both air and piping shall be approximately the same, and a uniform temperature shall be maintained throughout the test period. Leaks if observed shall be located and corrected. Products containing ammonia or chlorine shall not be used for locating leaks. Defective material shall be replaced. The test shall be conducted as follows: The pressure in the system shall be measured over a period of 3 minutes with a manometer or with a pressure-sensing device designed and calibrated to read, record, or indicate a pressure loss due to leakage during the pressure test period. (d) During the 3-minute period, a drop in pressure shall not occur. The system should be pressure tested for robustness at a pressure of at least 1.5 times the working pressure, as outlined in NFPA 54. Listed hose assemblies are excluded as they are individually tested during their manufacturer and listing process, as are regulators. Once the system is pressure tested, the regulators, typically on each end of the system can be assembled and leak tested by visual inspection. The bubble leak test was deleted as the devise cannot function correctly in this part of the system with regulators installed. This testing is comparable to the low pressure propane system tests currently outlined in and of this standard. 12

14 Log #67 Bruce A. Hopkins, RVIA Revise by deleting the last sentence which is redundant with so it reads as follows: The regulated high-pressure piping system shall be proven by test to be leak-free. by maintaining a test pressure of at least 30 psi (207 kpa) for a period of at least 10 minutes. This statement is redundant with the last sentence of (1) and therefore can be deleted. This is addressed in (Log #CP3). See Committee Action on (Log #CP3) Log #72 Add new (3) as shown: Tests shall be conducted by any of the following methods: (1) The piping system shall be pressurized to a minimum of 30 psi (207 kpa), and the system isolated from all sources of pressure. The pressure in the system shall be measured with a pressure sensing device, calibrated to read in increments of not greater than 2 psi (14 kpa). During the 10-minute period a drop in pressure shall not occur. (2) A bubble-type leak detector shall be installed between the source of pressure and this piping system. The bubble detector shall not indicate any airflow for a period of 1 minute. (3) The piping system shall be pressurized to a minimum of 30 psi (207 kpa), and all connections tested with either soapy water or a bubble solution. This test method is permitted in , and will provide a viable alternative for testing this high pressure piping system. At the higher pressure, this test method is even more likely to locate leaks than at lower pressure. This is addressed in (Log #CP3). See Committee Action on (Log #CP3) Log #22 Add new language as shown: (3) The piping system shall be pressurized to a minimum of 30 psi (207 kpa), and then the system isolated from all sources of pressure. All connections shall be tested for leakage with either soapy water or bubble solution. This provides another alternative method of testing that could be used to test regulator connections that could not be tested under either of the other methods. This is addressed in (Log #CP3). See Committee Action on (Log #CP3). 13

15 Log # Fuel-burning appliances installed or intended to be used only outside the recreational vehicle shall be listed for recreational vehicle use but shall not be required to be of the direct vent, sealed combustion type. This change clarifies and reduces any confusion that Exterior fuel-burning appliances must also be listed for installation on RV s Log #108 Bob Eugene, Underwriters Laboratories Inc Air supply ducts shall be made of galvanized steel, tin-plated steel, aluminized steel, or aluminum or made of Class 0 or Class 1 listed air ducts or air connectors as tested in accordance with ANSI/UL 181. Update standards titles to indicate ANSI approvals Log #109 Bob Eugene, Underwriters Laboratories Inc Registers, grilles, and fittings shall be made of a material classified 94 V-0 or 94 V-2 when tested as described in ANSI/UL 94, or shall be made of metal or material that complies with the requirements for Class 0 or Class 1 air ducts under ANSI/UL 181. Update standards titles to indicate ANSI approvals Log #110 Bob Eugene, Underwriters Laboratories Inc Air Conditioners with Heat Strips or Heat Pumps. Section 5.7 shall not apply to ducted rooftop air-conditioning systems with heat strips or heat pumps where the system does not exceed 175 F (80 C) when tested in accordance with ANSI/UL 484. Update standards titles to indicate ANSI approvals. 14

16 Log #68 Dale Jordal, Winnebago Ind. Inc Each recreational vehicle with a gasoline fuel fill having exterior combustion air inlet(s) at a level below the roof shall have a permanent exterior danger label in accordance with Section 4.3. The label shall contain the word "Danger" with minimum 1/4 (6 mm) high letters and body text with minimum 1/8" (3 mm) high letters on a contrasting background. The label shall be affixed in a visible location near the gasoline fuel filler spout and the propane container and shall read as follows: ***Insert artwork 1192_L68_R here*** ALL PILOT LIGHTS, APPLIANCES, AND THEIR INGNITORS (SEE OPERATING INSTRUCTIONS) SHALL BE TURNED OFF BEFORE REFUELING OF FUEL TANKS AND/OR PROPANE CONTAINERS. FAILURE TO COMPLY COULD RESULT IN DEATH OR SERIOUS INJURY. The intent of is to prevent gasoline fumes from becoming ignited by on board appliances during refueling. Since fueling stations may have both gasoline and diesel pumps next to or in the same fueling island a very real possibility exist that a 40-foot diesel RV may have its water heater or refrigerator vents next to another vehicle filling with gasoline. To meet the intent of this standard, it would make sense to expand this labeling to all fuel fills and not just limit it to the gasoline fills. This Danger Labeling applies to all RV with fuel fills as none are immune from the situation illustrated above Log #74 Revise the first sentence to read as follows: Each recreational vehicle with a gasoline fill and a propane appliance having exterior combustion air inlet(s) at a level below the roof shall have a permanent exterior danger label in accordance with Section 4.3. Adding the phrase propane appliance clarifies that exterior combustion air inlet(s) are not part of the gasoline fill. Merge this language into the Committee Action on (Log #68). The final language will replace the term gasoline with fuel per (Log #68). 15
