9 Gas Information

A. Fuel Conversion

C. Gas Connection

Before making gas connections ensure appliance being in- stalled is compatible with the available gas type.

Any natural or propane gas conversions necessary to meet the appliance and locality needs must be made by a quali- fied technician using Hearth & Home Technologies specified and approved parts.

Note: Have the gas supply line installed in accordance with local building 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.)

B. Gas Pressure

Proper input pressures are required for optimum appliance performance. Gas line sizing requirements need to be made following NFPA51.

WARNING

Fire Risk

Explosion Risk

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: A listed (and Commonwealth of Massachusetts approved) 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.

Refer to Reference Section 16 for location of gas line access in appliance.

Note: Gas line may be run from either side of appliance using one of the knockouts provided. Hole in outer shell NOT to exceed 2-1/2 in. and should never penetrate the firebox.

WARNING

Fire Risk

Explosion Risk

Verify inlet pressures.

•High pressure may cause overfire condition.

•Low pressure may cause explosion.

•Verify minimum pressures when other household gas appliances are operating.

Install regulator upstream of valve if line pressure is greater than 1/2 psig.

Pressure requirements for appliance are shown in table be- low. Minimum pressures must be met when other household gas appliances are operating.
