Vent Requirements; Altitude Considerations - Travis Industries 31 DVI GSB2 Owner's Manual

Installation (for qualified installers only)

Vent Requirements

Travis Industries manufactures a
vent kit specifically for this insert
(sku 96200330). It includes 30'
(10M) of vent, hose clamps, and a
prairie cap. The flashing on the cap
is 18" (458mm) by 18" (458mm).

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.

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.

Use the following vent:

3" UL 441 or 1777 Gas Liner for Exhaust and Air Inlet

Duravent Chimney Liner Termination Kit (3" & 3" Co-Linear to 6-5/8" Co-Axial w Flashing)

Simpson Duravent High-Wind Vertical Termination Cap (46DVA-VCH) or Prairie Cap

Altitude Considerations


This heater has been tested at altitudes ranging from sea level to 6,000 feet (1,800 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.
