NOTES:
(1) The four wood screws provided should be replaced with the appropriate fasteners for stucco, brick, concrete, or
other types of siding.
(2) For buildings with vinyl siding, a vinyl siding standoff (950), should be installed between the vent cap
and the exterior wall FIG-12. Attach the vinyl siding standoff to the horizontal termination. The vinyl
siding standoff prevents excessive heat from possibly melting the vinyl siding material. Note that the
horizontal vent termination bolts onto the flat portion of the vinyl siding standoff. (shaded area in FIG-
12), so that an air space will exist between the wall and the vent termination.
NOTES: (1) The horizontal run of vent pipe must be level and should have a 1/4” inch rise for every one foot of run towards the
termination. NEVER ALLOW THE VENT TO RUN DOWNWARD. This could cause high temperature and may
present the possibility of a fire
(2) The location of the horizontal vent termination on the exterior wall must not be easily blocked or
obstructed. Termination clearances are as follows: (SEE PAGE 8 IN THIS MANUAL)
(3) When installing a vent pipe in an enclosed chase the minimum clearance to combustibles is 4” inches
(100 mm).
