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 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 the stem/spring assembly in the pressure regulator.
Table 2 (page 3), provides the manifold pressure for altitudes
above 2,000 feet.
WARNING:
Shut off the gas supply at the manual gas shutoff
valve, before disconnecting the electrical power.
A fire or explosion may result causing property
damage, personal injury or loss of life. Failure to
follow the safety warnings exactly could result in
serious injury, death or property damage.
WARNING:
To avoid electric shock, personal injury, or death,
turn off the electric power at the disconnect or the
main service panel before making any electrical
connections.
WARNING:
The reduction of input rating necessary for high
altitude installation may only be accomplished with
factory supplied orifices. Do not attempt to drill out
orifices in the field. Improperly drilled orifices may
cause fire, explosion, carbon monoxide poisoning,
personal injury or death.
Before You Convert the Gas Valve
1. Turn the thermostat OFF or to its lowest temperature setting.
2. Verify the gas supply is shut OFF.
3. Verify the electrical power to the appliance is turned OFF.
Removing The Burner Orifices
1. Set the thermostat to the OFF position, or its lowest temperature
setting.
2. Shut OFF the gas supply at the manual shutoff valve located
outside of the appliance.
3. Turn off all electrical power to the appliance.
4. Remove the door from the burner compartment.
5. Move the gas valve ON/OFF switch to the OFF position as
shown in Figure 1. For VR8205Q2381 gas valves, turn the
knob to the OFF position.
6. Remove the wires from the terminals of the gas valve.
7. Remove the supply gas piping from the gas valve inlet.
8. Carefully remove four screws securing the gas manifold
assembly to the burner assembly.
9. Set the screws aside and remove the gas manifold assembly
from the appliance.
10. Carefully remove the burner orifices from the gas manifold
assembly.
11. Read the rating plate affixed to the appliance to determine
its rated input (Btu/hr) and the size of the factory installed
orifices.

IMPORTANT NOTE:
Before installing an orifice, check the side or face of the orifice
for the drill number to ensure that it is the appropriate size.
12. Install the appropriate LP/Propane gas burner orifices into
the gas manifold assembly.
NOTE: To prevent cross threading, hand tighten the orifices
into the gas manifold assembly until snug, then tighten with a
wrench.
WARNING:
Do not use Teflon tape or pipe joint compound
on the orifice threads. The hole in the orifice may
become blocked and cause fire, explosion, property
damage, carbon monoxide poisoning, personal
injury, or death.
13. Reinstall the gas manifold assembly to the burner assembly
with the 4 screws, that were removed earlier. NOTE: It is
important that the center of the orifices are aligned with the
center of the burners. It is recommended to fire the unit and
check alignment of the flame after converting to LP.
14. Reconnect the gas piping to the gas valve inlet.
15. Reconnect the wires to the gas valve terminals.
Single Stage Honeywell Valves
Models: VR8205S2890 or VR8215S1289
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.
1. Remove the cap screw from the gas valve as shown in Figure
2.
2. Remove and discard the plastic pressure regulator adjustment
screw from the gas valve. See Figure 3.
3. Remove the black colored spring from the gas valve.
4. Install the red spring from the conversion kit.
5. Install the new adjusting screw from the kit.
6. Check and adjust the regulator setting. See Gas Pressure
Adjustment Section (page 5).
7. Reinstall the cap screw.
8. Affix the label from the conversion kit to the gas valve.
