Important Information
This kit includes a Honeywell conversion kit for converting Honeywell VR8200, VR8205S, SV9500, SV9501 or VR8204M gas valves certified for use with Propane Gas (and so marked) to units functionally the same as the certified furnace for use with Natural Gas. If converting from propane gas to natural gas, the gas valve conversion kit, main burner orifices, and pilot orifice, all found in this kit, must be installed.
For converting the furnace from standard altitude on natural gas to high altitude (2001 feet above sea level or greater) on natural gas, the Honeywell conversion kit and pilot orifice changes are not needed. Only the main burner orifices require changing. Refer to Table 1 for proper orifice size for specific model number, input capacity, and installation altitude.
The orifices provided in this kit are stamped to indicate the size (twist drill number) and are sized for natural gas ONLY. Do NOT use them with butane or a mixture of butane and propane. The parts list specifies the size orifices supplied in the kit. Compare the size marking on the orifices with the sizes as listed in the parts list. Make sure you have the correct main burner orifices.
Extreme care is used to assure that this kit contains the proper orifices. Oversized orifices could result in hazardous conditions, especially if the venting is inadequate. For that reason, we recommend that the installer check the size of the orifice with a new twist drill of the correct size. This procedure assures that the orifices provided are the correct size.

!
FIRE, EXPLOSION, CARBON MONOXIDE POISONING HAZARD.
Failure to follow these instructions exactly could result in personal injury, death and/or property damage.
This conversion kit shall be installed by a qualified service agency in accordance with the manufacturer’s instructions and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed exactly, a fire, an explosion or production of carbon monoxide may result causing property damage, personal injury or loss of life. The qualified service agency is responsible for the proper installation of this kit. The installation is not proper and complete until the operation of the converted appliance is checked as specified in the manufacturer’s instructions supplied with the kit.
Gas Pressure
DRefer to the furnace rating plate for the approved gas input rating.
DGas input to burners MUST NOT exceed the rated input shown on rating plate.
DDo NOT allow minimum gas supply pressure to vary down- ward. Doing so will decrease input to furnace. Refer to Table 2 for gas supply and manifold pressures.
