9 90% GS FURNC - ORIFIC SLCTION CHRT - NTURL GS CUTION: Selection of the correct Natural Gas Orifice requires the following information for the specific installation: 1) ltitude in of the installation (ft.). 2) verage energy content of the Natural Gas fuel from the local supplier (BTU/cu. ft.). For detailed information and instructions for Orifice selection, see the Gas Furnace LP Conversion Kit Index and the latest edition of the National Fuel Gas Code Handbook, or the National Standard of Canada, Natural Gas and Propane Installation Code, CN B CUTION: This information is provided for replacement purposes only. Conversion for operation at High ltitude must be done using the kit specified on the product specification sheet for the unit. NOT: This Orifice sizing chart is based on 15,000 BTU/HR per burner. NOT: Factory installed orifices are calculated and sized based on a Natural Gas heating value of 15 BTU/cu. ft. and an elevation of ft. levation (ft.) nergy Value (BTU/cu. ft.) % GS FURNC - ORIFIC SLCTION CHRT - LP CUTION: Selection of the correct LP Orifice requires the altitude of the specific installation (ft.). For detailed information and instructions for Orifice selection, see the Gas Furnace LP Conversion Kit Index and the latest edition of the National Fuel Gas Code Handbook (NFG), or the National Standard of Canada, Natural Gas and Propane Installation Code, CN B CUTION: This information is provided for replacement purposes only. Conversion to LP or for operation at High ltitude should be done using the kit(s) specified on the product specification sheet for the unit. NOT: This Orifice sizing chart is based on 15,000 BTU/HR per burner. lso, the chart is developed using the specified pressure setting of 10 in. water column instead of the 11.0 in water column used by the NFG and CNB NOT: Orifices supplied in the LP Conversion Kit are calculated and sized based on an altitude of ft. levation (ft.)

15 NOTS Stk It is recommended that stock be maintained for this part. N/ Not pplicable 1 Top plate gasket is required for all new replacement top plates - order accordingly. 2 Order Gas Valve for Natural Gas along with LP Conversion Kit. 3 Units manufactured before F5109 used a limit switch with a set point different that the specified replacement. The specified replacement should be used for all units regardless of date code. 4 acket is not available for replacement. 5 Parts Bag deletion of Drain Tube requires that Tube be cut to length for horizontal applications on units produced after approximate date code F2209. DISCLIR: This document is intended to provide general replacement parts information to aid qualified service personnel in the repair of these models. The complete odel and Serial Number of the unit under repair should be specified when selecting and ordering replacement parts. Specifications and illustrations are subject to change without notice. Document supersedes all previous parts lists for these models. See for the latest revision of this document. The manufacturer assumes no obligation for errors or omissions. Service personnel must verify the proper and safe operation of equipment after the replacement of any original components. P.O. Box Fort Smith, R
