VENTING INSTALLATION INSTRUCTIONS

NOTICE: Read these instructions completely be- fore attempting installation.

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.

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.

IMPORTANT: Do not seal vent cap to pipe. Cap must be removable for service.

NOTICE: Failure to follow these instructions will void the warranty.

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

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.
