shelter installations that depend on internal air for
combustion (see Table 1).
Due to the higher risks and hazards of Liquid Propane
(LP) gas, Zodiac does not encourage installation of LP gas
heaters indoors. Please be sure to refer to section 4.2 for
additional precautions that must be considered for LP gas.
Section 3. Venting
3.1
Combustion Air Supply
As outlined in the latest edition of ANSI
(NFPA
54), the heater location must be properly vented
®
to provide sufficient air supply for proper combustion and
ventilation of the surrounding area.
In general, these requirements specify that the room in
which a heater is installed should be provided with two
permanent air supply openings:
•
one within 12 inches (305 mm) of the ceiling
•
one within 12 inches (305 mm) of the floor
All indoor installations must have openings to outside
air for combustion, ventilation, and dilution of flue
gases from inside the building. Do not, under any
circumstances, install this product in an indoor location
which does not provide combustion air to the appliance
from outside the building.
In addition, the heater must be completely isolated
and protected from any source of corrosive chemical
fumes such as those emitted by trichlorethylene,
perchloroethylene, chlorine, etc.
WARNING
Do not store any chemicals, cleaners, or other cor-
rosive 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.
Minimum Net Free Open Area* for Combustion
Openings (square inches/centimeters)
*Area indicated is for one of two openings:
one 12 inches from floor level, one 12 inches from ceiling level.

Table 1. Air Openings to Outside
NOTE: If using screens and/or metal louvers, compensate by
standard Z223.1
®
For special conditions, refer to Section 9.3.3.1 NFPA 54
ANSI Z223.
The information in Table 1 is not applicable in
installations where exhaust fans or blowers of any type are
used. Consult a Professional Engineer (P.E.) 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.
Outside Air Supply: 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 (1.2kW) input of the total input rating of all
appliances in the enclosed area.
If air is provided through horizontal ducts, each opening
and duct must provide 1 square inch of flow area for
each 2000 BTU/h (0.6 kW). These requirements are
summarized in Table 1.
Exhaust Fans or Vents: 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 flue
products to accumulate in the room. Additional air must
be supplied to compensate for such exhaust.
The information in Table 1 is not applicable in
installations where exhaust fans or blowers of any type
are used. Such installations must be designed by a
Professional Engineer (P.E.).

configuration, the JXi has a flue collar for attachment to
