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 AND/OR EXPLOSION HAZARD

5.

Failure to follow this warning could result in personal
injury, death, and/or property damage.

6.

Do NOT attempt to light the burner with a match or
flame of any kind.

HEATING INPUT RATE CHECK
The gas input to the unit is determined by measuring
the gas flow at the meter. Measuring gas flow at the
meter is recommended for natural gas units. To
measure the heating input, perform the following
steps:
1. Turn off all other gas appliances that use the same
meter.
2. Turn off gas supply to unit and attach manifold
pressure gauge as instructed in the ”Gas Valve
Adjustment” section.
3. With gas ON to the unit and the unit operating, record
the number of seconds for the gas meter dial to make
one revolution.
Table 3

Divide number of seconds in Step 3 into 3600
(number of seconds in 1 hour).
Multiply result of Step 4 by the number of cubic feet
shown for one revolution of the meter dial to obtain the
cubic feet of gas flow per hour.
Multiply result of Step 5 by Btu heating value of gas to
obtain total measured input in Btu/hr. Compare this
input rate with the Required Input Rate for the
installation altitude, as shown in Table 3. Consult with
local gas supplier if the heating value of gas is not
known.

Example: Assume that the size of the meter dial is 1 cu. ft.,
one revolution takes 44 seconds, and the heating value of
the gas is 1020 Btu/ft3. Proceed as follows:
1. 38 sec. To complete 1 revolution
2. 3600/38 = 94.7
3. 94.7 x 1 = 94.7
4. 94.7 x 1020 = 96,632 Btu/hr
For this example, the nameplate input is 100,000 Btu/hr, so
only a minor change in manifold pressure is required. In no
case should the final manifold pressure vary more than
+-- .3 ”water column from the values in Table 2. Never
exceed the required input rate (Table 3).
