Installation and Operation Manual
Une remise extérieure (au Canada seule-
ment) est un endroit inoccupé qui ne communique
pas directement avec les endroits occupés. Toutes
les installations intérieures et remises extérieures
exigent l’addition d’une cheminée approuvée par le
manufacturier. La cheminée doit être installée sans
aucune modification et selon les exigences fournies
par le manufacturier.
The applicable codes, standards and Zodiac
Pool Systems, Inc., require that the heater be properly
vented as outlined in this manual. Proper ventilation
of exhaust and combustion air are essential for the safe
and efficient operation of the heater. See
Section 3.
2.3.5.1 Converting the Grill to a Vent
Collar
If the LXi heater is to be installed either indoors
or in an outdoor shelter, its exhaust discharge grill
must be removed. The LXi heater comes with the
vertical vent collar factory installed. The optional side
vent plate, gasket and screws can be ordered as a parts
kit, see the parts list in
Section 11
of this manual. The
conversion can be done quite simply as follows:
1. Remove the vent exhaust grill by removing the
four screws which retain it. The grill and the
screws may be discarded. See Figure 5.
2. Install the vent pipe on the indoor vent collar.
The collar will accommodate vent piping of nom-
inal 6”, 7” or 8” diameter, see Table 4, depending
upon the model of your heater. See vent installa-
tion section for important information on select-
ing proper pipe size. See Figure 6.
Section 3. Venting
3.1
Combustion Air Supply
The heater location must provide sufficient air
supply for proper combustion and ventilation of the
surrounding area as outlined in the latest edition of
ANSI standard Z223.1 (NFPA
®
54). The minimum
allowable combustion air opening in the Canadian
Natural Gas and Propane Installation Code (CAN/CSA
B149.1) are not sufficient for safe and proper operation
of the LXi heaters. Combustion air openings must be
followed per the requirements of ANSI Z223.1 (NFPA
54) and Table 3.
In general, these requirements specify that the
room in which a heater is installed should be provided
with two (2) permanent air supply openings; one (1)
within 12 inches (305 mm) of the ceiling, the other
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. See Figure 7 and Table 3.
Zodiac Pool Systems, Inc., does not recommend
indoor installations that do not provide combustion air
from outside the building.
All outdoor shelter installations (Canada only)
must have uninterrupted openings to outside air for
combustion and ventilation. The installation must
be in accordance with the latest edition of CAN/
CSA B149.1.
For combustion air supply openings,
however, the requirements of Table 3 MUST be fol-
lowed for safe and proper operation.
The minimum
combustion air openings allowed in CAN/CSA B149.1
are NOT sufficient for the LXi heaters.
Zodiac Pool Systems, Inc., does not recommend
outdoor shelter installations that depend on internal air
for combustion. Combustion air should be ducted to
the heater from outside the structure.
Outside Air Supply:
When combustion air is
supplied directly through an outside wall, each open-
ing should have a minimum free area of 1 square inch
per 4,000 BTU/h (1.2kW) input of the total input rat-
ing 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 require-
ments are summarized in Table 3. Note that the areas
specified are net free areas and should be increased
when the openings are covered by screens, louvers,
grills or other protective covers. See Figure 8 and
Table 3 notes.
