These models are tested and approved for
use with DESA/Vexar (direct-vent) pipe com-
ponents and terminations.
The venting system must terminate on the
outside of the structure and can not be at-
tached to a chimney or ue 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.
This model is approved to be vented either
horizontally through an outside wall or verti-
cally through a roof or chase enclosure using
the following:
• 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 nish
such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which could
cause a re.
• 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.
• Have replace and selected vent compo-
nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall restops when penetrating
walls, ceilings or attic spaces.
• Install horizontal venting with a 1/4" rise for
every 12" of run toward the termination.
