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.

Refer to the furnace rating plate for the approved gas input
rating.
D
Gas input to burners MUST NOT exceed the rated input
shown on rating plate.
D
Do NOT
