Note: To assure top performance, safety and efficiency,
inserts must be installed with an approved flue liner as per
CAN/CGAB-149 orNational FuelGasCodeANSI Z223 and
these instructions.
Note: This installation must conform with local codes. In the

1 Listing and Code Approvals
C. High Altitude Installations
U.L. Listed gas appliances are tested and approved with-
out 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 feet, it may be necessary to decrease the input rat-
ing by changing the existing burner orifice to a smaller
size. Input rate should be reduced by 4% for each 1000
feet above a 2000 foot elevation in the U.S.A., or 10% for
elevations between 2000 and 4500 feet in Canada. If the
heating value of the gas has been reduced, these rules
do not apply. To identify the proper orifice size, check with
the local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.

Quadra-Firegas insertsare designedforrecessedinstalla-
tionsinto solidfuelmasonry orfactorybuiltnon-combustible
fireplaces that have been installed in accordance with the
National, Provincial, State and local building codes.
Prior to installing the gas insert:
• Have the chimney and adjacent structure inspected
and cleaned by qualified professionals. Hearth & Home
Technologies recommends that NFI or CSIA certified
professionals,or techniciansunderthe directionof certi-
fied professionals, conduct a minimum of a NFPA 211
Level 2 inspection of the chimney.
• Replace component parts of the chimney and fireplace
as specified by the professionals.
• Ensure all joints are properly engaged and the chimney
is properly secured.
When planning an appliance installation, it’s necessary to
determine the following information before installing:
• Minimum fireplace size. See Section 3.A.
• Gas supply piping.
• Electrical wiring.
• Finishing details.
• Existing mantel projections. See Section 10.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
B. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Pliers Hi temp caulking material
Hammer Flat blade screwdriver
Voltmeter Framing square
Gloves Variable speed drill
1/4 Hex drive Safety glasses
Manometer Phillips screwdriver
Tape measure Non-corrosive leak check solution
1/2 - 3/4 inch length, #6 or #8 Self-drilling screws
Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building, fire officials or
authoritieshavingjurisdictionaboutrestrictions,installation
inspection, and permits.
A. Design and Installation Considerations
Quadra-Fire direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
No additional outside air source is required.

C. Inspect Appliance and Components
• Carefully remove the appliance and components from
the packaging.
• The vent system components, surrounds and fronts are
shipped in separate packages.
• The fiber logs may be packaged separately and must
be field installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
• Read all of the instructions before starting the insta-
llation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
CAUTION

D. Inspect Firebox
Surface cracking or crazing of firebrick material is normal
andexpected. Thefollowingtypesof cracksareacceptable
and do not require replacement of the unit or the firebox:
• Cracks that do not propagate entirely through the
material.
• Lightfracturelines or “spider-webbing”on the surfaceof
the material.
• Cracks that are less than 1/32 in. wide and less than 3
in. long.
• If cosmetically unacceptable, such cracks may be
repaired with the SRV-PACK service kit. See Service
Parts List.
Cracks that are unacceptable:
• Cracks greater than 1/32 in. wide and 3 in. long are at
risk of growing.
• Cracks that penetrate entirely through the firebrick
material.
Inspection for cracking should be run when the appliance
is cool. Cracks tend to close as the appliance heats up.
