Vent Requirements; Vent Clearances; Vertical Penetrations Require Vent Firestop; Horizontal Penetrations Require Thimble - Travis Industries 4237 Installation Manual

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

Minimum Clearance to Vent

Vertical Penetrations Require Vent Firestop


A firestop (58DVA-FS) is required whenever the vent penetrates a ceiling, roof, or other horizontal
structure (passes through framing members).

Horizontal Penetrations Require Thimble


A wall thimble (58DVA-WT) is required whenever the vent penetrates a wall or other vertical structure
(passes through framing members).

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 8" diameter Simpson Dura-Vent Model Direct-Vent Pro (or GS)*.

Installation instructions for Simpson Dura-Vent may be found at www.duravent.com.
* Other vent may be approved with this fireplace. Check with the vent manufacturer for details).

Approved Vent Terminations


Horizontal terminations require the high-wind cap (58DVA-HC), vinyl standoff (58DVA-VSS), and the
horizontal termination shield (included with the fireplace). The high-wind sconce cap is not
allowed.

Vertical terminations require the high-wind cap (58DVA-VCH).

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).
