Installation & Operation Manual
3.3
Indoor and Outdoor Shelter Installation
Zodiac does not encourage installation of LP (liquid
propane) gas heaters indoors. Always consult with the
authority having jurisdiction (AHJ) along with all
applicable national and local codes before installing a LP
heater indoors. Please be sure to refer to
Section
4.2.
The heater is Certified by IAPMO-R&T Oceana for
indoor installations. Please keep in mind the 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
3.3.3
. 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 an equipment leak.
NOTE:
An outdoor shelter is an unoccupied enclosure which does
not communicate directly with occupied areas.
Zodiac Group Australia Pty, Ltd.,
does not recommend
outdoor
shelter installations that depend on internal air for combustion.

that temp rise limit does not

End of flue shall be:
●
At least 500 mm (20”) from the nearest
part of the roof.
● 300 mm (12”) from the nearest part of any
chimney.
●
If the roof is to be used for personal or
public use i.e. roof top patio/bar etc., flue
shall be adequately supported and At least 2
m (6.5’) above the roof level and 500 mm
(20”) above any surrounding parapet.
* AS5601 indicates two permanent openings, each with
the minimum free ventilation area indicated in the table.
** Direct to outside means any of the following options,
provided the ventilation path is unobstructed by building
material or insulation.
● Directly through an outside wall (prefered option).
● Through an outside wall but offset.
● into a cavity ventilated to outside.
● into an underfloor vent space ventilated to outside.
● Into a roof space ventilated to outside.
As outlined in the latest edition of ANSI
standard Z223.1 (NFPA 54), the heater
location must be properly vented to provide
sufficient air supply for proper combustion.
Please also consult Australian standards,
AS4560 and AS/NZS 5601.
When combustion air is supplied directly
through an outside wall, each opening
should have a minimum free area of 25.4
mm square (1 in
2
) per 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 25.4
mm square (1 in
2
) per 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 or reverse
the natural draft action of the venting
system. This could cause fl 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.
