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 specifi ed
and approved parts.
B. Gas Pressure
• Optimum appliance performance requires proper input
pressures.
• Gas line sizing requirements will be determined in ANSI
Z223.1 National Fuel Gas Code in the USA and CAN/
CGA B149 in Canada.
• Pressure requirements are:

Gas Pressure

Minimum inlet pressure
Maximum inlet pressure
Manifold pressure
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

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.
