OUTDOOR SHELTER INSTALLATION (CANADA)
See page 16 for 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
vent 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 6, 7
and 12. The vent should terminate with an approved vent
cap (weather cap) for protection against rain or blockage
by snow. Insulated 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 with adequate
ventilation and on a leveled floor, 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.
It is recommended to install the heater on fire-resistance
slabs. Do not install the heater directly on a combustible
wood floor without placing a non-combustible material
between the floor and the heater. Heaters must NEVER
be installed directly on carpeting.
Installations in basements, garages, or underground
structures where flammable liquids may be stored must
have the heater elevated 18 inches from the floor. The
following minimum clearances from combustible materials
must be provided.
The heater should not be installed closer than 6 inches to
any fences, walls or shrubs at any side or back, nor
closer than 18 inches at the plumbing side. A minimum
clearance of 24 inches must be maintained at the front of
the heater.
