VENTING INSTALLATION

INSTRUCTIONS

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.

WARNING: Seal all connec-

tions with high temperature

silicone every time a vent con-

nection is made. Before joining

elbows or pipes, apply a bead

of high temperature silicone

sealant to the male end of the

elbow or pipe. High temperature

silicone must also be used to re-

seal any connections after main-

tenance to venting system.

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

Consult local building codes before beginning the

installation. The installer must make sure to select

the proper vent system for installation. Before

installing vent kit, the installer must read this

fireplace manual and vent kit instructions.

Only a qualified service person should install

venting system. The installer must follow these

safety rules:

• 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

• Installation of any component part not manu-

factured or approved by DESA

• 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 serving a

separate solid fuel burning appli-

ance. Each gas appliance must

use a separate vent system. Do

not use common vent systems.

WARNING: Horizontal sec-

tions of this vent system require

a minimum clearance of 2" from

the top of the pipe and 1" mini-

mum to the sides and bottom.

Vertical sections of this system

require a minimum of 1" clear-

ance to combustible materials

on all sides of the pipe.

INSTALLATION PLANNING

There are two basic types of direct-vent installation:

• Horizontal Termination

• Vertical Termination

It is important to select the proper length of vent

pipe for the type of termination you choose. It is

also important to note the wall thickness.
For Horizontal Termination:

Select the amount

of vertical rise desired. The horizontal run of

venting must have 1/4" rise for every 12" of run

towards the termination.

WARNING: Never run the

vent downward as this may

cause excessive temperatures

which could cause a fire.

You may use one or two 90° elbows in this vent

configuration. See Horizontal Termination Con-

figurations on page 15.
