places. Installation and the provisions for combustion and
ventilation air must conform to the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, or the CSA B149.1, Natural Gas
and Propane Installation Code.
• This appliance must have a screen in place while the
appliance is in operation and, unless other provisions for
combustion air are provided, the screen shall have an
opening for introduction of combustion air.
• Solid fuels shall not be burned in a fi replace where a
decorative appliance is installed.
• If glass doors are present, the glass doors must be fully
opened while appliance is in operation.
Do NOT use this appliance if any part has been under

control system and any gas control which has been
under water.
WARNING
E. Gas Supply Connection
A 3/8 in. fl ared fi tting has been installed on the gas valve
inlet at the factory. Ensure fi ttings are of the appropriate size
and type on the gas line connection. If the tubing has to be
cut to length be sure to use the proper cutting and fl aring
tool. Also, be careful not to crimp the tubing while bending. If
the tubing becomes crimped, do not use for installation.
Gas resistant pipe compound must be used on all threaded
male connections to ensure a tight seal.
F. Gas Pressure
Proper input pressures are required for optimum appliance
performance. Gas line sizing requirements need to be made
following NFPA51.
Fire Risk
Explosion Risk
Verify inlet pressures.
• High pressure may cause overfire
condition.
• Low pressure may cause explosion.
Install regulator upstream of valve if line
pressure is greater than 1/2 psig.
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
• Gas Supply Pressure: Minimum inlet gas supply pressure
must be 7.0 in. W.C. for natural gas. The gas line
supplying the appliance must be suffi cient size to furnish
the appropriate supply pressure to the appliance while
operating in the “High” setting. (Minimum line ID of 1/2 in.
required if the line is longer than 20 ft.
• Pressure tap screws must be closed before turning gas
on to the appliance.
• Gas Line Pressure Test: Perform pressure test according
to state and local code (if pressure exceeds 1/2 in. psi (3.5
kPa)) before appliance is connected. Be sure to release
air pressure from the gas line before connection is made
to the appliance. Excessive pressure will damage the gas
control and may cause a gas leak.
• Gas Leak Test: Make sure the gas connections are tight.
Turn on the gas and coat each joint with a non-corrosive
gas leak check solution. Air bubbles will form indicating
any leaks. DO NOT USE A FLAME OR ANY TYPE OF
IGNITION SOURCE TO CHECK FOR LEAKS. All leaks
must be corrected before proceeding with installation.
• The appliance must only be installed in a solid-fuel burning
fi replace with the fl ue damper clamped open according
to Tables 1 and 2. The fi replace must be constructed of
non-combustible material.
• The minimum permanent free opening (in square inches)
that must be provided by the fi replace chimney or damper
to vent the fl ue gases is provided in Tables 1 and 2. If the
free opening is smaller than the specifi ed area, do not use
this appliance.
• The damper must be removed or fi xed in a manner in
which will secure it open. Some jurisdictions require the
damper to be removed or permanently welded fully open.
Check with state and local codes.
• Be sure that the chimney is completely unobstructed to
ensure proper ventilation of fl ue gases including carbon
monoxide (CO). CO (a poisonous gas) is tasteless,
odorless, colorless and undetectable without proper
equipment.
• Refer to Table 3 to determine minimum fi replace opening
requirements before proceeding.
