5 Gas Information
A. Fuel Conversion
Before making gas connections ensure appliance being 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 quali- fied technician using Hearth & Home Technologies speci- fied and approved parts.
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.
Low pressure may cause explosion.
Pressure requirements for appliance are shown in the table below.
Pressure | Natural Gas | Propane |
Minimum Inlet Pressure | 5.0 inches w.c. | 11.0 inches w.c. |
|
|
|
Maximum Inlet Pressure | 10.0 inches w.c. | 13.0 inches w.c. |
Manifold Pressure | 3.5 inches w.c. | 10.0 inches w.c. |
These pressures can be verified through the access panel as shown in Section E. Valve Access.
Note: A listed (and Commonwealth of Massachusetts approved) 1/2 in. (13 mm)
•If substituting for these components, please consult local codes for compliance.
Note: Gas line MUST be run from right side of appliance.
The access panel is located below the control box. It will be easier to make gas connection after the control box is in its final position. If necessary, relocate control box prior to making gas connection. See Section 5.E.
•Remove the screws holding the access panel.
•Set the panel and screws aside for reinstallation.

C. Gas Connection
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.)
If control box is to be relocated, move it at this time to avoid making the gas connection more than once.
•The incoming gas line can be installed from the bottom of the fireplace structure, from the side or from the rear (drilling through the cement board may be necessary).
•The incoming line should be connected to the 1/2 in. connection on the manual shutoff valve provided with the fireplace.
