Installation and Operation Manual
Une remise extérieure (au Canada seulement)
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 modication et selon les exigences fournies
par le manufacturier.
These 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
efcient operation of the heater. See Section 3.
The heater location must provide sufcient 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 sufcient for safe and proper
operation of the Legacy Model LRZ electronic 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 permanent air supply openings; one within
12 inches (305 mm) of the ceiling, the other within 12
inches (305 mm) of the oor.
All indoor installations must have openings to
outside air for combustion, ventilation, and dilution
of ue gases from inside the building, see Figure
5 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 followed for safe and proper operation. The
minimum combustion air openings allowed in CAN/
CSA B149.1 are NOT sufcient for the model LRZ
electronic 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
opening should have a minimum free area of one
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 one square inch
of ow area for each 2000 BTU/h (0.6 kW). These
requirements are summarized in Table 3. Note that
the areas specied are net free areas and should be
increased when the openings are covered by screens,
louvers, grills or other protective covers. See Figure 5
and Table 3 notes.

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 ue products to accumulate in the
room. Additional air must be supplied to compensate
for such exhaust.
The information in Table 3 is not applicable in
installations where exhaust fans or blowers of any
type are used. Such installations must be designed by
qualied engineers.
The heater must be completely isolated and
protected from any source of corrosive chemical fumes
such as those emitted by trichlorethylene, perchloro-
ethylene, chlorine, etc.

NOTE: If using screens and/or metal louvers, compensate by adding
50% additional area to each opening. If using wood louvers each
opening must be at least four times the area indicated in the table
above.
