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

•
The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill air
spaces with insulation.
Minimum Vent Configurations (see page 29)
Minimum Clearance Above Vent
Minimum Clearance to Sides & Below Vent
NOTE: Make sure to use the included wall thimble with this configuration.
All Other Vent Configurations
Minimum Clearance to Vent

Vent Firestop or Thimble

•
A firestop or thimble is required whenever the vent penetrates a wall, floor, or ceiling (passes through framing
members). See vent charts on page 29 and 31 for details

Altitude Considerations

•
This heater has been tested at altitudes ranging from sea level to 6,000 feet (1800 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

•
Always use the high-wind cap (part # 46DVA-HC, 58DVA-HC, or 46DVA-VCH). The high-wind sconce cap
or snorkel are not allowed.
•

All Other Vent Configurations
Use 8" or 6-5/8" diameter Simpson Dura-Vent Model Direct-Vent Pro (or GS)* (see vent configuration for
details).
* Other vent may be approved with this fireplace. Check with the vent manufacturer for details).

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).
