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 Z221.3 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

14.0 in. w.c.

14.0 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.

ASSEMBLY

Î

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 basepan and burner assembly. See Figure 11.1.

The lower access cover panel is removable if finishing material is not installed.

There is an access plate located on the left side of the firebox bottom. See Figure 11.2. Remove screws and plate to access the manual shutoff valve included with this fireplace. See Figure 11.3 and Figure 11.4. Depending upon local code, an additional manual gas shutoff, in an easily accessible area may be required and located upstream from the appliance.

Figure 11.2 Gas and Electrical Access

Note: Have the gas supply line installed in accordance with local codes, if any. If not, follow ANSI 223.1. Installation should be done by a qualified installer approved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter).

Note: A listed (and Commonwealth of Massachusetts ap- proved) 1/2 in. (13 mm) T-handle manual shut-off valve and flexible gas connector are connected to the 1/2 in. (13 mm) control valve inlet.

If substituting for these components, please consult local codes for compliance.
