VENTING INSTALLATION
NOTICE: Failure to follow these in-
structions will void the warranty.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.
INSTALLATION pRECAUTIONS
• Wear gloves and safety glasses for pro-
tection.
• 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 com-
ponent.
• Unauthorized modification of the venting
system (Do not cut or alter vent compo-
nents).
• Installation of any component part not
manufactured or approved by DESA Heat-
ing, LLC.
• Installation other than as instructed by
these instructions.
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 com
-
mon vent systems.
WARNING: Vent pipe air
space clearances to combus
-
tibles 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 combustible wall, 1" air space
clearance is required.
NOTICE: Read these instruc-
tions completely before attempt
-
ing installation.
These models are tested and approved for
use with DESA Heating, LLC (direct-vent) pipe
components and terminations.
The venting system must terminate on the out-
side 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 horizon-
tally on an outside wall, you may install
a standoff if the termination cap is to be
installed directly on a combustible finish
such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which could
cause a fire.
• Vent pipe air space clearances to com-
bustibles are 1" on all sides except on the
horizontal sections, which requires 2" clear-
ance 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 13).
• Have fireplace and selected vent compo-
nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall firestops when penetrating
walls and firestops when penetrating ceil-
ings or attic spaces.
• If using a venting configuration of only
horizontal venting with no vertical run, a
1/4" rise for every 12" of run toward the
termination is required.
• For installation of fireplace at elevations of
4000 feet or greater, pay special attention
to venting requirement recommendations.
WARNING: Read all instruc-
tions completely and thoroughly
before attempting installation.
Failure to do so could result in
serious injury, property damage
or loss of life.
