These models are tested and approved for use with DESA (directvent) 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 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. • Install horizontal venting with a 1/4" rise for every 12" of run toward the termination.
