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 its own separate vent system.
In addition to the requirements listed here, follow the requirements provided with the vent.
Vent Clearances
The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill air
spaces with insulation.
Minimum Vent Configurations (see page 27)
Minimum Clearance Above Vent
4" (104mm)
Minimum Clearance to Sides & Below Vent
1" (25mm)
NOTE: Make sure to use the included firestops with this configuration.
All Other Vent Configurations
Minimum Clearance to Vent
1" (25mm)
Vent Firestop
A firestop is required whenever the vent penetrates a wall, floor, or ceiling (passes through framing
members).
Altitude Considerations
This heater has been tested at altitudes ranging from sea level to 6,000 feet (1800 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.
Approved Vent
Always use the high-wind cap. The
high-wind sconce cap is not allowed
.

Vent Installation
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" (6mm) rise every 12" (305mm) of travel.
Horizontal sections require non-combustible support every three feet (e.g.: plumbing strap).
