Vent Requirements
!
Always maintain the required 1” (25 mm) clearance (air space) to combustible materials to prevent a fire
hazard. Do not fill air spaces with insulation.
!
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.
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.
!
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.

Slide the vent sections together and turn 1/4 turn until the sections lock in place.

Screws are not required to secure the vent. However, three screws may be used to secure
vent sections together if desired.
•
High temperature sealant is recommended at the appliance starter section connection (use
high-temperature silicone or Mill-Pac®).
•
If disassembly is required, at time of re-assembly check to see if the vent creates a tight fit. If
it does not, apply high temperature sealant to the joints of the affected sections.
•
Horizontal sections require a 1/4" rise every 12" of travel
