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 specified
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
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.
Note: Have the gas supply line installed in accordance with
local 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 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.
Note: This manual gas shutoff valve is accessible for service
by removing the base pan, burner assembly and valve plate.

Access Through the Valve Assembly
The lower access cover panel is removable if finishing
material has not been previously installed.
Remove media tray, base pan and burner assembly.
To access components:
1. Remove eleven screws around perimeter of valve
plate that secure valve plate to the firebox bottom.
See Figure 11.2.
2. Lift the valve plate from the back so that the gas valve
can clear the valve plate hole in the bottom the firebox.
See Figure 11.3.

3. Set the valve bracket on the front lip of the firebox bot-
tom. Turn "off" the ball valve. Disconnect gas valve
from the gas flex ball valve assembly at the pressure
fitting. See Figure 11.4.
