CAUTION: Selection of the correct Natural Gas Orifice requires the following information for the specific installation:

1) Altitude in of the installation (ft.).

2) Average 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 92-21519-59 and the latest edition of the
National Fuel Gas Code Handbook, or the National Standard of Canada, Natural Gas and Propane Installation Code, CAN B149.1.
CAUTION:This information is provided for replacement purposes only. Conversion for operation at High Altitude must be done using the kit specified
on the product specification sheet for the unit.

NOTE:This Orifice sizing chart is based on 15,000 BTU/HR per burner.
NOTE: Factory installed orifices are calculated and sized based on a Natural Gas heating value of 1075 BTU/cu. ft. and an elevation of 0 - 2000 ft.

CAUTION: 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 92-21519-59 and the latest edition of the
National Fuel Gas Code Handbook (NFG), or the National Standard of Canada, Natural Gas and Propane Installation Code, CAN B149.1.
CAUTION:This information is provided for replacement purposes only. Conversion to LP or for operation at High Altitude should be done using the
kit(s) specified on the product specification sheet for the unit.

NOTE:This Orifice sizing chart is based on 15,000 BTU/HR per burner. Also, 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 CANB149.1.
NOTE: Orifices supplied in the LP Conversion Kit are calculated and sized based on an altitude of 0 - 2000 ft.
