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 wall thimble is required whenever the vent penetrates a wall (sku# 250-05641). A thimble or
firestop (1” clearance) is required when passing through a floor or ceiling (passes through framing
members).
Always use the high-wind termination (if available from the vent manufacturer).
Drafting Performance
This direct vent appliance requires natural draft to operate (similar to a wood stove or other heating appliance). Draft
can be adjusted using the included restrictor. The restrictor settings detailed in the manual should be followed
(variations may occur depending upon installation parameters).
Many factors may negatively influence the draft of the appliance. Travis Industries will not be responsible for improper
draft due to factors such as trees, hills, buildings, obstructions, excessive wind, extreme hot or cold outdoor
temperatures, restrictive vent terminations, or influence from mechanical systems.
Vent Clearances
The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill
air spaces with insulation.

Altitude Considerations
This heater has been tested at altitudes ranging from sea level to 6,000 feet (1800M). 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.
