11 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 specified 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:
Gas Pressure | Natural Gas | Propane |
Minimum inlet pressure | 5.0 in. w.c. | 8.0 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. |
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.
WARNING
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.
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.
The lower access cover panel is removable if finishing material has not been previously installed.
Access Through the Valve Assembly
The lower access cover panel is removable if finishing 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 as well as valve bracket screw. See Figure 11.2 and Figure 11.5.
2.Lift the valve plate from the back so that the gas valve can clear the valve plate hole in the bottom the firebox. See Figure 11.3.
