WARNING:

All gas piping must conform with local building
codes, or in the absence of local codes, with the
most recent edition of the National Fuel Gas Code
ANSI Z223.1. DO NOT attempt to modify, or tap
into existing gas lines yourself. 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:

All electrical wiring must comply with the latest
edition of the National Electrical Code ANSI/
NFPA 70. Failure to follow these instructions
could result in possible damage to equipment,
serious personal injury, or death.

IMPORTANT: The installer performing this work assumes

all responsibility for this conversion. These instructions
are primarily intended to assist qualified individuals
experienced in the proper installation of these components.
Some local codes require licensed installation/service
personnel for this type of equipment. Safety should always
be the deciding factor when installing this product and using
common sense plays an important role as well. Improper
installation of the components or failure to follow safety
warnings could result in serious injury, death, or property
damage. After completing the installation, return these
instructions to the Homeowner’s Package for owner-user’s
future reference.

CONVERTING TO LP/PROPANE GAS AT

ALTITUDES BETWEEN ZERO & 10,000 FT.

Converting the two-stage gas valve to LP/Propane requires
the replacement of the burner orifices and/or the stem/
spring assembly in the pressure regulator.

Table 2 (page 4), 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 louvered access panel from the burner
compartment.

5. Move the gas valve ON/OFF switch to the OFF position
as shown in Figure 1.

6. Disconnect the 3-wire connector from the gas valve
terminal.

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 and
verify 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 1/2 to 1 full turn.
