9 Gas Information
A. Fuel Conversions
No fuel conversions allowed.
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.
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).
Note: A listed (and Commonwealth of Massachusetts ap- proved) 1/2 inch (13 mm)
•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 the appliance provided the hole in the outer wrap does NOT exceed
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.
Pressure | Natural Gas |
Minimum inlet pressure | 5.0 inches w.c. |
Maximum inlet gas pressure | 14.0 inches w.c. |
Manifold pressure | 3.5 inches w.c. |
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
