Fuel; Gas Pressure; Gas Connection - Homecrest CF-12 Manual

A. FUEL
Before making gas connections, ensure the appliance being installed is compatible with the available gas type.
B. GAS PRESSURE
Proper input pressures are required for optimum performance. Gas line sizing requirements need to be made following NFPA 54.
FIRE RISK.
EXPLOSION RISK:
• 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 psi.
Pressure requirements for the appliance are shown in the table below. Minimum pressures must be met when other household gas
appliances are operating.
PRESSURE
Minimum Inlet Pressure
Maximum Inlet Pressure
The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressures in
excess of 1/2 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).
C. GAS CONNECTION
Note:
Have the gas supply 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 approved) 3/8" T-handle manual shut-off valve and flexible gas connector are
connected to the 3/8" control valve inlet. If substituting for these components, please consult local codes for compliance.
Incoming gas line should be piped to the 3/8" connection on the manual shut-off valve.
