Gas Information
A. Fuel Conversion
• Make sure the appliance is compatible with available gas
types.
• Conversions must be made by a qualified service
technician using Hearth & Home Technologies specifi ed
and approved parts.
B. Gas Pressure
• Optimum appliance performance requires proper input
pressures.
• Gas line sizing requirements will be determined in ANSI
Z223.1 National Fuel Gas Code in the USA and CAN/
CGA B149 in Canada.
• Pressure requirements are:
WARNING! Risk of Fire or Explosion! High pressure
will damage valve. Low pressure may cause explosion.
• Verify inlet pressures. Verify minimum pressures when
other household gas appliances are operating.
• Install regulator upstream of valve if line pressure is
greater than 1/2 psig.
Gas Pressure Natural Gas Propane
Minimum inlet pressure 5.0 in. w.c. 11.0 in. w.c.
Maximum inlet pressure 10.0 in. w.c. 13.0 in. w.c.
Manifold pressure 3.5 in. w.c. 10.0 in. w.c.
Fire Risk.
Explosion Hazard.
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 1/2 psig.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 1/2 psig.
WARNING
Note: This appliance does include a manual gas shutoff valve
that is located in the valve compartment. This manual gas
shutoff valve is accessible for service by removing the base
pan, burner assembly and valve plate. See Figure 11.1.

4. Lift the valve assembly up and out to make necessary
service or repair.
Access Through the Valve Assembly
The lower access cover panel is removable if fi nishing
material has not been previously installed.
Remove Media Tray, Burner Assembly, and Base pan.
To access components:
1. Remove eleven screws around perimeter of valve
plate that secure valve plate to the fi rebox bottom.
