Gas Information
A. Fuel Conversion
Before making gas connections ensure appliance being in-
stalled is compatible with the available gas type.
Any natural or propane gas conversions necessary to meet
the appliance and locality needs must be made by a quali-
fi ed technician using Hearth & Home Technologies specifi ed
and approved parts.
B. Gas Pressure
Proper input pressures are required for optimum appliance
performance. Gas line sizing requirements need to be made
following NFPA51.
WARNING
Fire Risk
Explosion Risk
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
Fire Risk
Explosion Risk
Verify inlet pressures.

Install regulator upstream of valve if line
pressure is greater than 1/2 psig.
Pressure requirements for appliance are shown in table
below.

C. Gas Connection
Note: Have the gas supply line installed in accordance
with local building 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
approved) 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.
Optional: A 5 ft fl exible gas line is available to those regions
which do not require black pipe to be used. See Service
Parts List (Section 13).
Note: Gas line MUST be run from right side of appliance.
WARNING
Gas Leak Risk
•
Support control when attaching pipe to
prevent bending gas line.
Note: The gap between supply piping and gas access hole
may be plugged with non-combustible unfaced insulation
to prevent cold air infi ltration.
•
Ensure that gas line does not come in contact with outer
wrap of appliance. Follow local codes.
•
Incoming gas line should be piped into the valve
compartment and connected to the 1/2 in. connection on
the manual shutoff valve.
