WARNING:
All gas piping must conform with local building
codes, or in the absence of local codes, with the
most recent edition of CGA B149.1. 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 Canadian Electrical Code (CSA
C22.1 and/or local codes). Failure to follow these
instructions could result in possible damage to
equipment, serious personal injury, or death.
1. STOP! Read all the steps in the “Before you Convert the Unit”
section above.
2. Disconnect the flame sensor wire at the burner box. See
Figure 1 (page 3).
3. Disconnect the spark ignitor wire at the burner box.
4. Remove the white wires from the Stage-1 terminal of the gas
valve. Remove the brown wire from the Stage-2 terminal of
the gas valve. Remove black common wire from gas valve.
5. Remove (if installed) supply gas piping from the gas valve.
6. Remove 4 fasteners that secure the gas manifold to the burner
box. Carefully remove the gas manifold assembly from the
burner box.
NOTE: The gas manifold assembly consists of the gas valve,
the gas manifold, and the orifices.
7. Identify the gas valve manufacturer listed on the gas valve
label. Convert the valve for operation with LP gas as described
in the appropriate manufacturers instructions.
CONVERTING TO LP / PROPANE GAS
(AT ALTITUDES BETWEEN ZERO & 10,000 FT.)
1. Examine the rating plate of the unit to determine Model number
and rated input (Btu/hr).
2. Count the number of burners in the burner box. Verify all
information in Table 1 to determine the appropriate LP gas
orifice size for your application.
3. Install the appropriate LP gas burner orifices into the gas
manifold.
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.
IMPORTANT NOTES:
• Before installing an orifice, check the face or side of
the orifice for the drill number to ensure that it is the
appropriate size.
• To prevent cross threading, hand tighten the orifices
into the gas manifold assembly until snug, then tighten
with a wrench 1/2 to 1 turn.
• For units converted for operation above 2,000 ft., follow
the High altitude deration instructions.
4. 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.
5. Reconnect the gas piping to the gas valve inlet.
6. Reconnect the wires to the gas valve terminals.
7. Reconnect the wires to the flame sensor and spark igniter.
BEFORE YOU CONvERT ThE UNIT
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.
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 burner access panel.
5. Move the gas valve ON/OFF knob to the OFF position. See
