See page 17 for (Indoor) Vent Adaptors
All products of combustion and vent gases must be
completely removed to the outside atmosphere through
a vent pipe which is connected to the stack adaptor. A
vent pipe extension of the same size must be connected
to the indoor stack adaptor and extended at least 2 feet
higher than highest point of the roof within a 10 foot
horizontal radius, and at least 3 ft. higher than the point
at which it passes through the roof, or as permitted by
local code; see Figures 11 and 12. The vent should
terminate with an approved vent cap (weather cap) for
protection against rain or blockage by snow. Double-
wall vent pipe and an approved roof jack shall be
employed through the roof penetration.
The heater must be located as close as practical to a
chimney or gas vent.
CAUTION
The heater should be installed at least 5 feet away
from the pool or spa.
The heater must be placed in a suitable room on a non-
combustible floor or on a non-combustible base and in
an area where leakage from heat exchanger or water
connections will not result in damage to the area
adjacent to the heater or the structure. When such
locations cannot be avoided, it is recommended that a
suitable drain pan with adequate drainage, be installed
under the heater. The pan must not restrict air flow.
Installations in basements, garages, or underground
structures where flammable liquids may be stored must
have the heater elevated 18 inches from the floor using
a non-combustible base. The following minimum
clearances from combustible materials must be
provided.
