Vertical Venting
(see Figure 5, Page 15)
The vent pipes must be connected to the proper collars on the unit and
the exhaust vent pipe must be connected to the termination cap or the unit
will not operate. When done assure all connections are securely fastened.
The fireplace and fireplace chimney must be clean and in good working
order and constructed of non-combustible materials. Inspect chimney
cleanouts for proper fit and seal.
Make sure that both liners will pass through existing damper area.
Remove or lock damper to allow the passage of the flexible liners. If
the damper will not allow the passage of both liners, DO NOT PROCEED
FURTHER. (If fireplace is masonry) Consult a local mason for removal
of the damper without risk of structural damage or leakage (if the fire-
place is factory built) The appliance may NOT be installed into the fireplace.
WARNING
Direct-Vent Fireplace Insert Vent Requirements - Use liner
listed to UL181 (Factory-made Air Ducts And Air Connec-
tors) or UL1777 (Chimney Liners) for the AIR INTAKE. Use
liner listed to UL1777 ONLY for the EXHAUST.
Do not substitute the heat-rated flex liner (UL1777) for
the exhaust with any other type liner or a fire may result
causing property damage, personal injury or loss of life.
Zero Clearance Fireplace Installation
This appliance may be installed in a masonry or factory built/zero clear-
ance (ZC) fireplace. When installing in a ZC fireplace, the ZC grate must
be removed and the ZC damper must be removed or secured open. The
ZC doors, screen, refractory or masonry lining, baffles and smoke shelf
may be removed if necessary to install the gas insert. However, do not cut
or alter the fireplace components. The removal of any parts to facilitate
installation must not alter the integrity of the inner or outer shells of the
fireplace cabinet. Any parts removed must be replaceable if the insert is
taken out of the fireplace or the fireplace clearly marked with a paint stick
that "This fireplace has been altered and is no longer safe to operate."
If the factory-built fireplace has no gas access hole(s) provided, an access
hole of 1.5" (38.1 mm) or less may be drilled through the lower sides or
bottom of the firebox in a proper workmanship like manner. This access
hole must be plugged with a non-combustible insulation after the gas
supply line has been installed.
Si le foyer préfabriqué ne comporte pas d’orifices d’amenée du gaz,
un orifice d’au plus 38,1 mm (1,5 po) peut être pratiqué, selon les
règles de l’art, dans la partie inférieure des parois ou au fond de
la chambre de combustion. Cet orifice doit être obturé au moyen
d’isolant incombustible une fois la conduite de gaz en place.
The installer must mechanically attach the marking supplied with the gas
fireplace insert to the inside of the firebox of the fireplace into which the
gas fireplace insert is installed. See Figure 1 on Page 11.

Flue Restrictor
The flue restrictor settings shown in
Figure 7
a
re for typical installations
and are based upon laboratory testing. To achieve proper combustion,
adjustments may be needed to account for variables in the installation,
elevation, and typical operating temperatures.
Allow the appliance to burn for at least 10 minutes before determining
proper flame appearance. If the proper flame appearance cannot be
achieved, the flue restrictor may need to be changed to a different posi-
tion. See the following guidelines to determine if you need to readjust
the flue restrictor.
Flue Restrictor Adjustment
1. Using a phillips screwdriver, remove the two screws holding the flue
restrictor in place.
2. Refer to table in Figure 7 and position the flue restrictor to the recom-
mended setting and reattach with the two screws removed in step 1.
Symptoms - Lack of Combustion Air
If the symptoms listed below are present, you may need to adjust the
flue restrictor to a more open position.
• Flame appears yellow
• Floating Flames (lazy, ill defined, quiet, may roll)
• Sooting
• Pilot becomes yellow and appliance shuts down
Symptoms - Excessive Combustion Air
If the symptoms listed below are present, you may need to adjust the
flue restrictor to a more closed position.
• Low Flame
• Pilot pulls and appliance shuts down
• Pilot flame ghosts
