This conversion kit is only to be used to convert natural

gas furnaces to LP/Propane gas in the United States.

For installations in Canada, the Canadian conversion kit

must be used.

Table 1 is a detailed listing of the components in the LP

gas conversion kit. Please check the contents of the

conversion kit with that of the parts listing, and familiarize

yourself with each component.

IMPORTANT: When converting a low NOx furnace from

natural gas to LP/Propane gas, it is necessary to remove

the NOx Bafﬂes from the furnace.

CONVERTING TO LP/PROPANE GAS AT ALTITUDES BETWEEN ZERO & 10,000 FT. Converting single stage valves to LP/Propane requires the replacement of the burner orifices and/or the spring found under the cap screw in the pressure regulator. Converting 2 - stage valves to LP/Propane requires the replacement of the burner orifices and/or the stem/spring assembly in the pressure regulator. Table 2 (page 3), provides the manifold pressure for altitudes above 2,000 feet.

Single Stage Honeywell Valves 2 - Stage Honeywell Valves Models: VR8205S2890 or VR8215S1289 Model VR8205Q2381 IMPORTANT NOTE: When converting to LP/ Propane gas from natural gas, the black spring in the gas valve must be replaced by the red spring in the kit. IMPORTANT NOTE: When converting to LP/ Propane gas from natural gas, the white stem/ spring assembly in the gas valve must be replaced by the black stem/spring assembly in the kit. 1. Remove the cap screw from the gas valve as shown in Figure 2.

Gas Pressure Adjustment Model VR9205Q1127 IMPORTANT NOTES: • When converting to LP/Propane gas from natural gas, the springs from gas valve must be replaced by the larger springs from the kit.The LP/Propane springs for both HIGH & LOW fire are the same size, shape and color. • Use only a Torx-25 or 3/16” flathead screwdriver when removing adjustment screws or during pressure adjustment. 1. Remove the HIGH fire cap screw. See Figure 5. 2. Remove and discard the HIGH fire adjustment screw from the gas valve.
