Sound power ratings shall be referenced 10-12 watts. A factory dynamic balance shall be made on all fans after their assembly. An IRD or PMC analyzer shall be used to measure velocity, and the final reading shall not exceed 0.1 inches per second. The exact level of vibration shall be recorded on the fan as proof of the final dynamic balance at the factory. HEAT EXCHANGER The heat exchanger shall be of two-pass design, made up of at least 16-gauge stainless steel drum and tubes. The primary and secondary heat transfer surfaces shall be constructed of Type 409 series stainless steel, with internal stainless steel high efficiency enhancing baffles. The stainless steel tubes shall be continuously welded into the secondary front and rear header tube sheets to ensure an airtight seal. Units shall be provided with multiple condensate drains. The heat exchanger section shall have an internal radiation shield to maintain a jacket loss of less than 2% of rated output. All heat transfer surfaces, including headers and the front collector box, shall be inside the casing and in the airstream. The construction of the heat exchanger shall permit free, unrestricted lateral, vertical, and peripheral expansion during the heating and cooling cycle without damage or strain to any parts. The burner shall be constructed with at least 14-gauge stainless steel and with the air baffles being made up of 430 stainless steel to ensure high durability and life of the burner. The burner assembly shall be a blow through positive pressure type with an intermittent pilot ignition system. Flame supervision shall be with a solid state programmed flame relay complete with flame rod. The unit s burner motor and modulating gas valve must be electronically controlled to guarantee, to the customer, a highly efficient unit at all times and applications. The unit efficiency shall be a minimum of 80% through the entire operating range and shall be independently tested and verified by ETL. The main and pilot 36
HTDM SPECIFICATION manifolds shall be completely factory pre-piped to the burner. This assembly must be factory wired and include the following minimum components: main and pilot manual shut-off valves, main and pilot regulators, main and pilot automatic shut-off valves and adequate union and test ports for unconstrained service. All indoor units can be vented using type B vent without a draft hood on all models in Canada. In the United States, indoor units can be vented using type B vent without a draft hood on models 200, 400 and 600 and with a diverter on models 1000 and 1400 to assure safety and guarantee that all combustible gases leave the unit. There must also be a means of collecting and disposal of condensate formed in the flue gas by means of a 409 stainless steel flue box with drain and heat exchanger drain. Drains shall be made of copper (stainless steel) tubing. CONTROLS Units must be controlled electronically to achieve a turndown of at least 23:1 and to guarantee the heat exchanger efficiencies of at least 80%. Unit controller must be a true proportional integral (PI) controller to maintain the turndown and unit efficiencies. The controller must be able to electronically adjust the burner blower and modulating gas valve to maintain ideal combustion levels. The controller shall monitor the amount of combustion air available to guarantee proper emission standards. Unit control will consist of a highly accurate feedback control system. Corrective action in this system is taken only when the balance has been upset due to a change in the disturbance variable. Any other control that does not behave in this manner is unacceptable. An amplitude decay ratio of one quarter is essential to the stability. Sine wave pattern cycling is unacceptable. Control must be achieved with a PI control algorithm. The ICECON1 controller analyzes the process calculates a control error from the measured values. The control error will vary from positive to negative depending on whether the value of the controlled variable is greater than or less than the set point. Continuous cycling of the burner or blower is unacceptable. The proportional control in the ICECON1 controller will provide an output signal in proportion to the size of the control error. The longer the control error is present, the more the controller output will change. If the control error persists, the output will continue to ramp in the correct direction, until the control error is eliminated. The ICECON1 modulation controller is compatible with the following external inputs: Discharge air sensor. Discharge air sensor with space override thermostat. Discharge air sensor with remote temperature selector and space override thermostat. Discharge air sensor with high and low temperature remote temperature selector and space reset thermostat. 0-10 volt dc signal from building management system. 4-20 ma signal from building management system.
