OUTSIDE AIR

Outside air must not be drawn from an enclosed
space (garage, unventilated crawl space).
Note: Napoleon strongly suggests using outside air
for all residential installations, especially for those
that are energy effi cient, air-tight homes.
Outside air supply must not be over 15' long.
Outside air vents must be made with 1 3/4" diameter
or larger metal or aluminum duct with a metal screen
attached to the end to keep out rodents (P.V.C. or
other materials may not be used).
The outside air inlet must not be above or within 12"
of the chimney termination, must have a rain cap or
down-turned elbow to prevent the water from enter-
ing and be located so that it will not become plugged
by snow or other material.
MOBILE HOME
Installation into a Mobile Home should be in ac-
cordance with the manufactured home and safety
standard (HUD), CFR 3280, part 24.
Outside air is required (used for combustion).
The heater must be bolted to the fl oor (Some states
do not require this; check with your local building
department).
