Technical Data
This is the safety alert symbol. This symbol alerts you to potential hazards that can kill
or hurt you and others.
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in minor or
moderate injury. It may also be used to alert against unsafe practices.
Conversion of the appliance for operation at high altitudes (> 2000 ft, 610 m) requires the completion of the
section, Adjust Gas Pressure Settings, using the high altitude manifold test pressures above. No parts need to
be replaced for high altitude.
For high altitude installations in Canada, the conversion shall be carried out by a manufacturer’s authorized
representative, in accordance with the requirements of the manufacturer, provincial or territorial authorities
having jurisdiction and in accordance with the requirements of CAN/CGA-B149.1 or CAN/CGA-B149 installation
codes.
The input rate can be verified by following the procedure in the National Fuel Gas Code (NFPA54 / ANSI Z223.1,
2006 or latest edition).

Conversion Procedure
The gas supply shall be shut off prior to disconnecting the electrical power, before
proceeding with the conversion.
Gain Access
Replace Components
Confirm that the inlet gas pressure is between the minimum and maximum pressures allowed for this appliance.
1. Hold both ends of the bottom cover (Undercover
assembly) and pull toward you to remove the
cover. Cover snaps in place.
2. Remove the 7 screws that hold the front panel and
the louver assembly to remove panel from the unit.
Pull the panel out at the bottom about 4 inches
(100mm) and lift up over clips that hold it in place at
the unit’s top.
3. Remove 1 screw from the bracket with the overheat
switch. Place bracket to the side out of your way.
Refer to the Technical Data and Parts List to ensure to
the correct injectors and dampers are installed.
1. Remove the 2 manifold screws. Rotate the
manifold and connecting tube to access the
injectors.
2.
Replace the 2 injectors with the proper size for the
gas type to be used.
3.
Remove the burner screw from the burner
assembly.
4. Replace the primary and secondary dampers with
the dampers for the gas type to be used. (Pull the
secondary damper straight out using the tab on the
side.)
5. Install the manifold (2 screws) and overheat switch
bracket (1 screw).
6. Confirm that the electrode and leads are installed.

the manometer is properly calibrated.
5. Turn on the gas and power supply to the
appliance. With the unit in the Off position, press
the SW1 switch at the top of PC board until it
beeps.
6. Select the correct code on the LED display using
▲ and ▼ buttons:
High altitude is above 2000 ft (610 m).
L1: Propane gas at low (sea level) altitude
L2: Propane gas unit at high altitude
A1: Natural gas at low (sea level) altitude
A2: Natural gas unit at high altitude
7. Press the SW1 test button to record the gas type
code into memory. The LED will display “F1”. If
not shown, use the ▲ and ▼ buttons to obtain
“F1”.
8. Press the SW1 switch to enter this code into
memory.
9. The LED will display the temperature scale. Use
