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 fol-

lowing guidelines:

•  When venting system terminates horizontally

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 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.

•  If using a venting configuration of only hori-

zontal 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.

•  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 sys-

tem (Do not cut or alter vent components)

•  Installation of any component part not manu-

factured or approved by DESA

•  Installation other than as instructed by these

instructions
