12 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.

11.5 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: 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 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.

C. Gas Connection

•Refer to Reference Section 17.A. for location of gas line access in appliance.

•Gas line may be run through knockout(s) provided.

•The gap between supply piping and gas access hole may be caulked with caulk with a minimum of 300ºF continuous exposure rating or stuffed with non-combustible, unfaced insulation to prevent cold air infiltration.

•Ensure that gas line does not come in contact with outer wrap of the appliance. Follow local codes.

•Pipe incoming gas line into valve compartment.

•Connect incoming gas line to the 1/2 in. (13 mm) connection on manual shutoff valve.

WARNING! Risk of Fire or Explosion! Support control when attaching pipe to prevent bending gas line.

•A small amount of air will be in the gas supply lines.

WARNING! Risk of Fire or Explosion! Gas build-up dur-

ing line purge could ignite.

•Purge should be performed by qualified service technician.

•Ensure adequate ventilation.

•Ensure there are no ignition sources such as sparks or open flames.

Light the appliance. It will take a short time for air to purge from lines. When purging is complete the appliance will light and operate normally.

WARNING! Risk of Fire, Explosion or Asphyxiation! Check all fittings and connections with a non-corrosive commercially available leak-check solution. DO NOT use open flame. Fittings and connections could have loos- ened during shipping and handling.

WARNING! Risk of Fire! DO NOT change valve settings. This valve has been preset at the factory.

D. High Altitude Installations

NOTICE: If the heating value of the gas has been reduced, these rules do not apply. Check with your local gas utility or authorities having jurisdiction.

When installing above 2000 feet elevation:

•In the USA: Reduce burner orifice 4% for each 1000 feet above 2000 feet.

•In CANADA: Reduce burner orifice 10% for elevations between 2000 feet and 4500 feet. Above 4500 feet, consult local gas utility.
