3.3 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-certifi ed 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 3.3.5. 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.
If the outdoor shelter is a completely closed
structure, air openings in accordance with the
size recommendations described in Section 3.3.1
must be maintained. If the structure does not have
outside air openings then air must be provided for
combustion by using our fresh air vent kit.
As outlined in the latest edition of ANSI
®
standard Z223.1 (NFPA
®
54), the heater
location must be properly vented to provide
suffi cient 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 effi ciency and reliability
and increased emissions. 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).
