D. High Altitude Installations
U.L. Listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 feet in the
U.S.A. and Canada.
When installing this appliance at an elevation above 2000 ft,
it may be necessary to decrease the input rating by chang-
ing the existing burner orifice to a smaller size. Input rate
should be reduced by 4% for each 1000 ft above a 2000 ft
elevation in the U.S.A., or 10% for elevations between 2000
and 4500 ft in Canada. If the heating value of the gas has
been reduced, these rules do not apply. To identify the prop-
er orifice size, check with the local gas utility.
If installing this appliance at an elevation above 4500 ft (in
Canada), check with local authorities.

into position if using an FPS prefab enclosure.
• Level the appliance from side to side and front to back.
• Shim the appliance with non-combustible material, such
as sheet metal, as necessary.
• Bend out nailing tabs on each side.
• Keep nailing tabs flush with the framing.
• Secure the appliance to the framing by using nails or
screws through the nailing tabs.
Fire Risk
• Prevent contact with sagging, loose
insulation.
• Do NOT install against vapor barriers or
exposed insulation.
WARNING

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-
fied technician using Hearth & Home Technologies specified
and approved parts.
Pressure requirements for appliance are shown in table
below.
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 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
approved) 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: The gap between supply piping and gas access hole
may be plugged with non-combustible unfaced insulation
to prevent cold air infiltration.
B. Gas Pressure
Proper input pressures are required for optimum appliance
performance. Gas line sizing requirements need to be made
following NFPA51.
WARNING
Gas Leak Risk
• Support control when attaching pipe to
prevent bending gas line.
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

Gas Information
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
Note: Gas line MUST be run from right side of appliance.
These pressures can be verified through the internal valve
access panels as shown in E. Valve Access.
Pressure Natural Gas Propane
Minimum Inlet Pressure 5.0 inches w.c. 11.0 inches w.c.
Maximum Inlet Pressure 7.0 inches w.c. 11.0 inches w.c.
Manifold Pressure 3.5 inches w.c. 10.5 inches w.c.
C. Gas Connection
Optional: A 5 ft flexible gas line is availavle to those regions
which do not require black pipe to be used. See Service
Parts List (Section 13).
• 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.

WARNING
Fire Risk
Explosion Risk
• Gas build-up during line purge may
ignite.
• Purge should be performed by qualified
technician.
• Ensure adequate ventilation.
• Ensure there are no ignition sources such
as sparks or open flames.
WARNING
CHECK FOR GAS LEAKS
Fire Risk
Explosion Risk
Asphyxiation Risk
• Check all fittings and connections.
• Do not use open flame.
• After the gas line installation is complete,
all connections must be tightened and
checked for leaks with a commercially
available, non-corrosive leak check
solution. Be sure to rinse off all leak check
solution following testing.
Fittings and connections may have loosened
during shipping and handling.
D. High Altitude Installations
U.L. listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 ft in the USA
and Canada.

WARNING
D. Frequently Asked Questions
C. After the Appliance is Lit
Initial Break-in Procedure
When you light the appliance, you may notice that it pro-
duces heat which does have an associated odor or smell. If
you feel this odor is excessive it may require the initial three
to four hour continuous burn on high followed by a second
burn up to 12 hours to fully drive off any odor from paint and
lubricants used in the manufacturing process. Condensation
of the glass is normal
Issue Solutions
Condensation on the glass This is a result of gas combustion and temperature variations. As the appliance warms, this condensation will
disappear.
Blue flames This is a result of normal operation and the flames will begin to yellow as the appliance is allowed to burn for 20 to
40 minutes.
Odor from appliance When first operated, this appliance may release an odor for the first several hours. This is caused by the curing of
the paint and the burning off of any oils remaining from manufacturing.
Film on the glass This is a normal result of the curing process of the paint and logs. Glass should be cleaned within 3 to 4 hours of
initial burning to remove deposits left by oils from the manufacturing process. A non-abrasive cleaner such as gas
fireplace glass cleaner may be necessary. See your dealer.
Metallic noise Noise is caused by metal expanding and contracting as it heats up and cools down, similar to the sound produced
by a furnace or heating duct. This noise does not affect the operation or longevity of the fireplace.
Is it normal to see the pilot
flame burn continually?
In an Intellifire ignition system it is normal to see the pilot flame, but it should turn off when ON/OFF is turned off.
In a standing pilot system the pilot will always stay on.
