DANGER
CARBON MONOXIDE GAS IS DEADLY – Exhaust
from this pool heater contains toxic levels of carbon
monoxide, a dangerous, poisonous gas you cannot see
or smell.
All products of combustion and vent gases must be
completely removed to the outside atmosphere through
a vent pipe which is connected to the draft hood. A
vent pipe extension of the same size must be connected
to the draft hood 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 15 and 16. 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 use of
double-walled type B vent pipe is recommended.
The draft hood must be installed so as to be in the
same atmospheric pressure zone as the combustion
air inlet to the pool heater. The certified (factory)
draft hood must not be modified in any way and
must be employed in every indoor installation.
The heater must be located as close as practical to
a chimney or gas vent. 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.
