These models are tested and approved for use with DESA (direct-
vent) pipe components and terminations.
The venting system must terminate on the outside of the structure and
can not be attached to a chimney or flue system serving a separate
solid fuel or gas burning appliance. A direct-vent appliance must have
its own venting system. DO NOT common vent this appliance.
These models are approved to be vented either horizontally through
an outside wall or vertically through a roof or chase enclosure using
the following guidelines:
• When venting system terminates horizontally on an outside wall,
you may install a standoff if the termination cap is to be in-
stalled directly on a combustible finish such as vinyl, wood,
stucco, etc.
• Never run the vent downward as this may cause excessive tem-
peratures which could cause a fire.
• Vent pipe air space clearances to combustibles are 1" on all sides
except on the horizontal sections, which requires 2" clearance
from the top of the pipe. Where the termination cap penetrates a
combustible wall, 1" air space clearance is required.
• Snorkel terminations are required when minimum clearance to grade
cannot be met (see Figure 16 on page 11).
• Have fireplace and selected vent components on hand to help
determine the exact measurements when elbowing or offsetting.
Always use wall firestops when penetrating walls and firestops
when penetrating ceilings or attic spaces.
• Install horizontal venting with a 1/4" rise for every 12" of run
toward the termination.
VENTING INSTALLATION
INSTRUCTIONS
NOTICE: Read these instructions completely be-
fore attempting installation.
WARNING: Read all instructions completely and
thoroughly before attempting installation. Failure to
do so could result in serious injury, property damage
or loss of life.
NOTICE: Failure to follow these instructions will void
the warranty.
WARNING: This gas fireplace and vent assembly
must be vented directly to the outside. The venting
system must NEVER be attached to a chimney serv-
ing a separate solid fuel burning appliance. Each
direct-vent gas appliance must use a separate vent
system. Do not use common vent systems.
WARNING: Vent pipe air space clearances to com-
bustibles are 1" on all sides except on the horizontal
sections, which require 2" clearances from the top of
the pipe. Where the termination cap penetrates a com-
bustible wall, 1" air space clearance is required.

Installation Precautions
INSTALLATION PRECAUTIONS
• Wear gloves and safety glasses for protection
• Use extreme caution when using ladders or when on roof tops
• Be aware of electrical wiring locations in walls and ceilings
The following actions will void the warranty on your venting
system:
• Installation of any damaged venting component
• Unauthorized modification of the venting system (Do not cut
or alter vent components)
• Installation of any component part not manufactured or ap-
proved by DESA
• Installation other than as instructed by these instructions
