Initial Break-in Procedure
• The appliance should be run three to four hours
continuously on high.
• Turn the appliance off and allow it to completely cool.
• Remove fixed glass assembly. See Section 12.F.
• Clean fixed glass assembly. See Section 3.
• Replace the fixed glass assembly and run continuously
on high an additional 9 hours.

pliance break-in.
• Some people may be sensitive to smoke and odors.
• Smoke detectors may activate.
K. After Appliance is Lit
L. Frequently Asked Questions
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 al-
lowed to burn for 20 to 40 minutes.
Odor from appliance Whenfirst operated, this appliance may release an odor for the firstseveral hours.This is caused by the curing of the paint and the burning off of any oils remaining from manufacturing. Odor may
also be released from finishing materials and adhesives used around the appliance.
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 appliance.
Is it normal to see the pilot flame burn
continually?
In an intermittent pilot ignition system (IPI), the pilot flame should turn off when appliance is
turned off. Some optional control systems available with IPI models may allow pilot flame to
remain lit.

B. Design and Installation Considerations
Heat & Glo gas inserts are designed for installations into
solid fuel masonry or factory built fireplaces that have
been installed in accordance with the National, Provin-
cial, State and local building codes. Fireplaces are to be
constructed of non-combustible materials and, in the ab-
sence of local or regional codes, meet criteria of NFPA
211. No additional outside air source is required.
Installation MUST comply with local, regional, state and na-
tional codes and regulations. Consult insurance carrier, local
building inspector, fire officials or authorities having jurisdic-
tion over restrictions, installation inspection and permits.
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,ortechnicians underthedirection ofcerti-
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 combustible mantel and surround clearances
comply with applicable codes and regulations for solid-
fuelfireplaces. Intheabsenceof localor regionalcodes,
refer to NFPA 211.
• Ensure all joints are properly engaged and the chimney
is properly secured.
• Minimum fireplace size. See Section 5.A.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Finishing details.
• Whether optional accessories—devices such as a wall
switch or remote control—are desired.
D. Inspect Appliance and Components
• Carefully remove the appliance and components from
the packaging.
• The vent system components and decorative doors and
fronts may be shipped in separate packages.
• If packaged separately, the log set and appliance grate
must be installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
•Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged, in-
complete or substitute components. Keep appliance dry.
C. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Tape measure Framing material
Pliers Flat blade screwdriver
Hammer Phillips screwdriver
Gloves Framing square
Voltmeter Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Level Reciprocating saw
Manometer Noncorrosive leak check solution
1/2 - 3/4 inch length, #6 or #8 Self-drilling screws
Caulking material (300º F minimum continuous exposure
rating)
Stove cement (1200ºF or higher continuous exposure
rating)

7 Installation Preparation
Prepare the existing solid fuel masonry or factory built
non-combustible firebox for installation.
A. Inspection and Cleaning
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,ortechnicians underthedirection ofcerti-
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.
• Ensure combustible mantel and surround clearances
comply with applicable codes and regulations for solid-
fuelfireplaces. Intheabsenceof localor regionalcodes,
refer to NFPA 211.
• Ensure chimney is constructed of non-combustible
materials.
• Ensure chimney is clean and in good working order.
• Ensure that all chimney cleanouts fit properly to prevent
air leakage into chimney.
B. Flue Damper
Fully lock the solid fuel fireplace’s flue damper in the open
position, OR completely remove it.
C. Gas Line
Note: If the factory built fireplace has no gas access hole
provided, an access hole of 1 inch (25 mm) diameter or
less maybedrilledthrough thelowersidesorbottomofthe
fireboxin aproperworkmanship- likemanner.Thisaccess
holemustbepluggedwithnon-combustibleinsulationafter
the gas supply line has been installed.
• Install gas line into firebox cavity.
• Check local codes and gas line sizing requirements
following NFPA51. See Section 9.
• It is recommended that extra length of gas line be
installed within the existing wood burner or masonry
fireplaceto allowremoval ofthe insertforfutureservicing
needs.
E. Electrical Outlet Box
An outlet box may be installed in a bottom back corner of
the existing solid fuel masonry or factory built fireplace to
power the appliance. Each insert ships standard with a
cord assembly to permit blowers or other optional acces-
sories to be used. The accessories plug into the new out-
let box or may be routed out onto the hearth to a nearby
outlet.
D. Fireplace Conversion Notice
Permanently attach the label with the following warning to
theinsidelower backofthe fireplace fireboxintowhich the
insert is being installed. Silicone or mechanical fasteners
may be required to properly secure the label.
WARNING! Risk of Fire! This fireplace has been con-
verted for use with a gas fireplace insert only and cannot
be used for burning wood or solid fuels unless all original
parts have been replaced, and the fireplace re-approved
by the authority having jurisdiction.
