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

1) Furnace Input Rating (BTU/HR)

2) Number of Burners

2) Altitude (ft.) For detailed information and instructions for Orifice selection, see the Gas Furnace LP Conversion Kit Index 92-21519-47 and the latest edition of the National Fuel Gas Code Handbook, or the National Standard of Canada, Natural Gas andPropane 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 kitspecified on the product specification sheet for the unit.

NOTE:This Orifice sizing chart is based on a Natural Gas heatingvalue of 1075 BTU/cu. ft and a pressuresetting of 3.5 in. water column. NOTE: Factory installed orifices are calculatedand sized based on a Natural Gas heating value of 1075 BTU/cu. ft. and an elevation of 0 - 2000ft.

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

1) Furnace Input Rating (BTU/HR)

2) Number of Burners

2) Altitude (ft.) For detailed information and instructions for Orifice selection, see the Gas Furnace LP Conversion Kit Index 92-21519-47 and the latest edition of the National Fuel Gas Code Handbook, or the National Standard of Canada, Natural Gas andPropane 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 usingthe kit(s) specified on the product specification sheet for the unit.

NOTE:This Orifice sizing chart is developed using the specifiedpressure setting of 10 in. water column insteadof the 11.0 in water column used bythe NFG and CANB149.1. NOTE: Orifices supplied inthe LP Conversion Kit are calculated andsized based on a heating value of2500 BTU/cu. ft. and an elevation of0 - 2000 ft.

NOTES

Stk It is recommended that stock be maintained for this part.

N/A Not Applicable

1 A small number of early production RKMB series were built with "2B" gas control components, but were labeled

with a " 2A" serial number.The units labeled with " 2A" have the " 2B" gas control parts. 2 Order the specified LP Conversion Kit 3 Order Gas Valve for Natural Gas along with LP ConversionKit 4 Harness as supplied is complete except for vacancy in pin positions 1 and 4 (orange wires for Limit Control). If

needed, these will have to be field fabricated or reused and inserted into harness plug.
