Figure 6. Outdoor heater location.
1.12 meters above the top of the heater. The area
under the overhang must be open on three sides. This
stops combustion gases from being diverted into living
areas through doors, windows, or gravity inlets.
Protect the heater from direct water drainage.
Do not place the heater with the top of the casing
(flue outlet) within 2 meters of any opening into a
building (see Figure 6).
Due to the chance of down-draughts caused
by high wind conditions, place the heater at least 1
meter from vertical surfaces, such as nearby buildings
and walls. The addition of an outdoor flue terminal
assembly which is optional, may ease the problem.
2D-3. Flooring - Typical Installation
Except as described below, place all heaters on a
noncombustible surface. A heater can be placed on a
combustible floor by placing a non-combustible base
under the heater, available from Zodiac Pool Systems,
Inc. See the heater rating plate for the base part
number. Do not place the heater directly on carpeting
Place the heater to provide adequate clearance
on all sides for inspection, (see Table 4, Page 7)
service and to provide adequate air circulation for
proper operation. Make sure that the location of the
heater complies with the requirements detailed in
these instructions for ventilation, clearances, and flue
system.
2D-2. Outdoor Installation
Place the heater in an area where leakage of the
heater or connections will not result in damage to the
area around the heater or to the structure. If this is not
possible, provide a suitable drain pan to catch and
divert any leakage. The pan must not restrict air flow.
Place the heater in an open, unroofed area, and
keep the clearances detailed in Table 4.
Do not place the heater in an area where leaves
or other combustible materials can gather around the
base or on top of the heater.
Do not place the heater close to sprinklers that
could spray water on it. Excess water could damage
the heater.
The heater must be installed at least 1.52 meters
from the edge of the pool or spa unless separated
from the pool or spa by a solid fence, wall, or other
permanent barrier. If you are placing the heater under
an overhang, there must be a minimum clearance of
