Venting Installation
NOTICE: Read these instructions completelybeforeattempting installation.
These models are tested and approved for use with DESA Heating, LLC
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
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:Readallinstructions 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 war- ranty.
NOTICE:Donotsealtermination cap to vent pipe. Cap must be removable for vent inspection and maintenance.

The following actions will void the warranty on your venting system:
•Installation of any damaged venting com- ponent
•Unauthorized modification of the venting sys- tem (Do not cut or alter vent components)
•Installation of any component part not manufactured or approved by DESA Heat- ing, LLC
