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.
A firestop is required whenever the vent penetrates a wall, floor, or ceiling (passes through framing
members). Firestops may be provided by the vent manufacturer (1” clearance).
Vent Clearances
The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill
air spaces with insulation.
Minimum Clearance to Vent
1" (25mm)
Altitude Considerations
This fireplace has been tested at altitudes ranging from sea level to 6,000 feet (1800 M). In this testing we have
found that the fireplace, 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
Use listed 10” or 8” B-Vent (see power vent for diameter used). The actual exterior dimension will
vary (typically 11” 279mm or 9” 229mm outer diameter). This vent is available from Travis Industries.
Vent Installation
Secure the sections together (twist sections together, secure with screws - see vent manufacturer
instructions for detailed requirements).
Horizontal sections require non-combustible support every three feet (e.g.: plumbing strap)
WARNING: Do not use screws longer than 1/4" to secure the B-Vent together
.
If long screws are used to secure the vent together, the screw will penetrate the outer wall of the vent then
deflect the inner wall. This makes the inner wall bend inwards, creating unwanted turbulence and resistance
inside the vent (see picture below to the right). This decreases exhaust flow and may negatively impact vent
durability. See the vent manufacturer instructions for maximum screw size.
Make Sure Screws are Not Longer than 1/4”
Long Screws Create an Inward Bend (Flair)
1/4” Crimptite
(works fine)
1/2" Tek Screw
(too long)
