Installation & Operation Manual
4.3 Indoor and Outdoor Shelter Installation
Due to the higher risks and hazards of liquid propane
(LP) gas, Zodiac
®
does not encourage installation of LP
gas heaters indoors, refer to Section 4.3.
The heater is CSA design-certied for indoor installations
in the US and for outdoor shelter installations in Canada.
Please keep in mind the service and combustible surface
clearances from Section 3.1 when selecting an installation
location. You will also need to make considerations for
intake combustion air see Section 3.3.1 and exhaust
venting see Section 3.3.4. In addition, when pool
equipment is installed indoors, appropriate containment
measures and drains should be considered for the
prevention of property damage in the event of a water leak.
NOTE: An outdoor shelter is an unoccupied enclosure which does
not communicate directly with occupied areas.
Zodiac Pool Systems, Inc., does not recommend US outdoor
shelter installations that depend on internal air for combustion.

All outdoor

circumstances,

As outlined in the latest edition of ANSI
®
standard Z223.1 (NFPA
®
54), the heater
location must be properly vented to provide
sufcient air supply for proper combustion.
When combustion air is supplied directly
through an outside wall, each opening should
have a minimum free area of 1 square inch
per 4,000 BTU/h (1.2 kW) input of the total
input rating of all appliances in the enclosed
area. If combustion air must pass through
horizontal ducts, each opening should have
a minimum free area of 1 square inch per
2,000 BTU/h (1.2 kW) input of the total
input rating of all appliances in the enclosed
area. Details can be found in Figure 4.
The “Minimum Net Free Open Area”
information from Figure 4 is not applicable
in installations where exhaust fans
or blowers of any type are used. Any
equipment which exhausts air from the room
where the heater is installed can deplete
the combustion air supply which could
lead to poor combustion, decreased heater
efciency and reliability and increased
emissions. This could cause ue products to
accumulate in the room. Additional air must
be supplied to compensate for such exhaust.
Consult a professional engineer to ensure
that installations where exhaust fans or
blowers are used are designed and installed
in accordance with all applicable local and
national installation codes.
In addition, the heater must be completely
isolated and protected from any source
of corrosive chemical fumes or corrosive
vapors (i.e chlorine or hydrochloric acid).
WARNING
Do not store any chemicals, cleaners, or other
corrosive material near combustion air openings
or in the room. Avoid locating appliance vents in
the vicinity of combustion air openings. Failure
to prevent corrosive materials from mixing with
combustion air can result in reduced heater life
and unsafe heater operation.
