HEATILATOR ECO-CHOICE
Do not terminate vent
in any enclosed or semi-enclosed
area such as a carport, garage, attic, crawl space, under a
sun deck or porch, narrow walkway or closely fenced area,
or any location that can build up a concentration of fumes
such as a stairwell, covered breezeway, etc.
CAUTION
1
.
Termination must exhaust above air inlet elevation.
It is
strongly recommended that at least 60 inches (1.5m)
of vertical pipe be installed when appliance is vented
directly through a wall.
This will create a natural draft,
which will help prevent the possibility of smoke or odor
venting into the home during a power outage. It will also
keep exhaust from causing a nuisance or hazard by
exposing people or shrubs to high temperatures. The
safest and preferred venting method is to extend the vent
vertically through the roof.

Distance from
doors and opening windows, or gravity or
ventilation air inlets into building:
