Vent must be at least 2.4 m (8 ft) away from
nearest vertical surface. Vents extending 1.5 m (5 ft)

COMBUSTION AIR SUPPLY
For indoor installation, the heater location must provide
sufficient air supply for proper combustion and ventilation
of the surrounding area (
in accordance with AS/NZS
5601.1
).
The minimum requirements for the air supply specify that
the room in which a heater is installed should be provided
with two permanent air supply openings; one within
30 cm (12 in) of the ceiling, the other within 30 cm (12in)
of the floor for combustion air, in accordance with the AS/
NZS 5601.1 as applicable, and any local codes that may
apply. These openings shall directly, or through duct,
connect to outdoor air.
Pentair Water Pool and Spa, Inc. does not recommend
indoor installations that do not provide combustion
air from outside the building.

VENT INSTALLATION –
INDOOR INSTALLATION OR OUTDOOR SHELTER
Flueing must be in accordance with AS/NZS 5601.1
Always vent the heater to the outdoors, see Note*.
• Vent it vertically using double wall vent connector pipe.
Locate the heater so as to minimize the length of horizontal venting and the number of vent elbows required. Horizontal
vent runs must slope to allow exhaust condensate to drain and it is recommended to have a condensate drain as described
in the venting installation instructions.
