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 Information
Gas Pressure Natural Gas Propane
Minimum inlet pressure 5.0 in. w.c. 11.0 in. w.c.
Maximum inlet pressure 10.0 in. w.c. 13.0 in. w.c.
Manifold pressure 3.5 in. w.c. 10.0 in. w.c.
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 qualifi ed 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 fi tter).
Note: A listed (and Commonwealth of Massachusetts ap-
proved) 1/2 in. (13 mm) T-handle manual shut-off valve
and fl exible 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.
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.
WARNING
WARNING! Risk of Fire or Explosion! High pressure
will damage valve. Low pressure could 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.
• Valve pressure taps are accessible by removing the
decorative front and the bottom glass shield.
Figure 9.1. Valve Pressure Taps.
Note: This appliance does include a manual gas shutoff
valve that is located in the valve compartment. This manual
gas shutoff valve is accessible for service by removing the
decorative front and the bottom glass shield. The valve is
most accessible if it is located forward in the control cavity
of the appliance.
Depending upon local code, an additional manual gas
shutoff, in a readily accessible area may be required and
located upstream from the appliance.
The bottom panel is removable if fi nishing material is not
installed. See Figure 9.2.

C. Gas Service Access
If the fi nishing materials have been installed around the
appliance opening, proceed as follows:
1. Remove bottom glass shield.
2. Remove screws on left and right sides of component
heat shield and lift it out of the control cavity.

3. Unplug the 6V transformer from the junction box.
This will turn the power off to the appliance.
CAUTION! Risk of Overheating! Component heat shield
MUST be installed before operating appliance. Electrical
components will be damaged.
