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.

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.

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.

A. Fuel Conversion 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.
