The location of the vent terminal depends on the following
minimum clearances and considerations (see illustration):
Twelve (12) inches grade level and above normal
snow levels.
Four (4) feet below, or four (4) feet horizontally from any
door, window, soffit, under eave vent or gravity air inlet to
the building or other appliances, or from gas or electric
meters. Do not locate vent above walkways, doors,
windows, air inlets, gas or electric meters or other
equipment.
Ten (10) feet from any forced air inlet to the building.
Any fresh or make-up air inlet such as for a dryer or
furnace area is considered to be a forced air inlet.
Eighteen (18) inches from an inside corner formed by two
exterior walls.

Horizontal Vent Terminal Location
Do Not install vent terminal under any patio or deck.
To help prevent moisture from freezing on walls and under
eaves, do not locate vent terminal on the side of a building
with prevailing winter winds.
Do Not terminate vent pipe directly on brick or masonry
surfaces. Use a rust-resistant sheet metal backing plate
(2x2feet) behind vent. (See illustration.)
Do Not locate vent terminal too close to shrubbery, as flue
gasses may damage them.
Caulk all cracks, seams and joints within six (6) feet of vent
terminal.
All painted surfaces should be primed to lessen the chance of
physical damage. Painted surfaces will require maintenance.
Insulate vent pipe exposed to cold conditions (attics, crawl
spaces, etc.) with inflammable material to help prevent
moisture from accumulating in vent pipe.
Do Not extend exposed vent pipe outside of building.
