Vent Requirements
! The gas appliance and vent system must be vented directly to the outside of the building, and never
be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each direct vent gas
appliance must use it's own separate vent system.
! Make sure the exhaust pipe on the heater connects to the exhaust portion of the cap. The
illustrations below show how the flex liners should be attached.
• The exhaust vent must reline the entire length of the chimney and terminate above the chimney top
! Be careful not to crimp or rupture the liner when bending it into chimney offsets
• When installed, the vent must meet all of the vent
manufacturer's requirements
• Make sure to order the following:
- 3” UL 441 Gas Liner for Air Inlet and Exhaust
- Dura-Vent Adapter & Flashing (part # 923GK).
- Vertical Termination Cap (Dura-Vent pt # 991)
Altitude Considerations
This heater has been tested at altitudes ranging from
sea level to 8,000 feet (2,400 M). In this testing we
have found that the heater, with its standard orifice,
burns correctly with just an air shutter adjustment. If local
codes require resizing the orifice, in the U.S.A. refer to
ANSI 223.1, Appendix P, in Canada B-149.1 or B-149.2
! Failure to adjust the air shutter properly may lead to
improper combustion which can create a safety hazard.
Consult your dealer or installer if you suspect an
improperly adjusted air shutter.

Vent Restrictor
WARNING: Restrictor adjustment
should only be done by a qualified
installer.
Only those installations
determined to be over-drafting
require this adjustment. The best
indication of over-drafting is a
hyper-active flame pattern (flames
that move too quickly). If the air
shutter is constricted, the flames
become short and yellow, yet still
very active. Over-drafting may
affect the pilot, but this is not the
best way to determine over-
drafting. Over-drafting is most
likely in tall venting configurations
(especially if using an “Exhaust
Only Re-Line”). Do not over-
restrict the vent (this leads to
ghosting or lifting flames - reduce
restrictor setting).

NOTE:
Position #1 is the
fully open position
Determine a restrictor position. Start low(move
the restrictor a maximum two positions at a time)
and thoroughly test the heater before adjusting further.
Remove the screw with a 1/4" nutdriver (or screwdriver).
Rotate the adjustment plate clockwise until the correct index hole is below the pivot point.
Insert the screw into the correct index hole and tighten.
