Vent Requirements; Altitude Considerations; Clearances; Use Of 8" Dia. Pipe - Travis Industries DVS EF Fireplace Owner's Manual

Installation

Vent Requirements

• Always maintain the
required 1" clearance (2"
clearance above the vent
when an elbow is placed
directly off the top of the
fireplace) 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.
• In addition to the
requirements below, follow
the requirements provided
with the vent.
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.
Approved Vent
• Use of of the following 6-5/8" diameter co-axial gas direct vent systems:
• 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
• Horizontal sections require non-combustible support every three feet (e.g.: plumbing tape)
