8 Gas Information
A. Fuel Conversions | C. Gas Connection |
Before making gas connections ensure that appliance be- ing installed 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 qualified 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 Pressures
Proper input pressures are required for optimum appli- ance performance. Gas line sizing requirements need to be made following NFPA54.
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.
WARNING
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 the table below. Minimum pressures must be met when other household gas appliances are operating.

•If substituting for these components, please consult local codes for compliance.
Refer to Reference Section 15 for location of gas line access in appliance.
NOTE: Gas line may be run from either side of the appliance provided the hole in the outer wrap does NOT exceed
WARNING
Gas Leak Risk
•Support control when attaching pipe to prevent bending gas line.
NOTE: The gap between supply piping and gas access hole may be caulked with high temperature caulk or stuffed with
•Ensure that gas line does not come in contact with outer wrap of appliance. Follow local codes.
•Incoming gas line should be piped into the valve compartment and connected to the 1/2 inch connection on the manual shutoff valve.
•Check all fittings and connections of appliance which may have loosened during shipping.
