types.
• Conversions must be made by a qualified service
technician using Hearth & Home Technologies specified
and approved parts.
B. Gas Pressure
WARNING
Fire Risk.
Risk of Fire! Risk of Explosion!
Incorrect pressure will damage valve.
• Isolate 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.
• 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 when in operation are:
Gas Pressure
Minimum inlet pressure
Maximum inlet pressure
Manifold pressure
• 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.
Note: Have the gas supply line installed in accordance with
local codes, if any. If not, follow ANSI Z223.1. 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 in. (13 mm) T-handle manual shut-off valve
and flexible gas connector are connected to the 1/2 in. (13
mm) control valve inlet.
• If substituting for these components, please consult
local codes for compliance.
