Jandy® Legacy™ Model LRZM Pool/Spa Heater by Zodiac®
If the heater cannot be placed so as to meet the
requirements stated in Section 2.3.4, a vent pipe and
cap may be added to the heater to move the exhaust
vent opening to a position that complies with the
requirements. When the heater is installed in areas of
high wind or when unavoidably installed near a verti-
cal obstruction where downdrafting may occur, it may
be desirable to add a vent cap directly to the top of
the heater. In all cases, vent pipes and caps must be of
the same diameter as the exhaust outlet of the heater.
Approved vent caps may be obtained through your
Jandy distributor.
3.2.2 indoor and outdoor Shelter
installations
WaRNiNG
Vent pipe diameter must be as required by the Na-
tional fuel Gas Code ANSI Z223.1 or the Canadian
Installation Codes for Gas Appliances CAN/CSA-
B149.1. Undersize pipe can result in inadequate
venting and oversize pipe can result in vent conden-
sation. In either case the result can be release of
combustion products to the indoors. This can cause
serious injury or death by carbon monoxide poison-
ing or asphyxiation.
aveRtiSSeMeNt
Le diamètre des tuyaux de ventilation doit répondre
aux exigences du
National Fuel Gas Code
ANSI
Z223.1 ou du code canadien des installations des
appareils à gaz CAN/CSA-B149.1. Des tuyaux trop
petits risquent d’entraîner une ventilation inadé-
quate et des tuyaux trop gros risquent de provoquer
une condensation dans les tuyaux. Dans un cas
comme dans l’autre, des produits de combus-
tion risquent de s’échapper dans le bâtiment et
causer des blessures graves ou l’asphyxie par le
monoxyde de carbone.
All indoor installations and outdoor shelter
installations require the addition of a factory approved
draft hood. The draft hood must be installed without
modification.
All vent installations must be made in accordance
with all local, state or provincial codes and with:
1. Chapter covering "Venting of Equipment" of
the national Fuel Gas Code, ANSI 223.1 latest
edition , or the applicable provisions of the local
building codes.
2. In Canada, CAN/CSA-B149.1.
Avoid long horizontal runs of the vent pipe, and
90° elbows, reductions and restrictions. Horizontal
runs must have at least a 1/4 inch rise per foot (20mm
per meter) in the direction of flow.
These requirements are summarized in Table
3. Note that the areas specified are net free areas and
should be increased by 50 percent when the openings
are covered by screens, louvers, grills or other protec-
tive covers. See Figure 5 and Table 3.
Note
Except for the combustion air openings
requirements, in Canada, follow Canadian
Standard, CAN/CSA-B149.1 or local codes.
Follow the requirements of Table 3 for the
minimum combustion air openings required.
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 3 is not applicable in
installations where exhaust fans or blowers of any type
are used. Such installations must be designed by quali-
fied engineers.
If a blower or fan is used to supply air to the
room, the installer should make sure it does not create
drafts which could cause nuisance shutdowns of the
pilot.
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.
WaRNiNG
Do not store any chemicals, cleaners, or other cor-
rosive material near combustion air openings or in
the room. Avoid locating dryer vents in the vicin-
ity of combustion air openings. Failure to prevent
corrosive materials from mixing with combustion air
can result in reduced heater life and unsafe heater
operation.
aveRtiSSeMeNt
N’entreposer aucun produit chimique, produit net-
toyant ou produit corrosif à proximité des bouches
d’air de combustion ou dans la pièce. Éviter de
placer des tuyaux de ventilation pour sécheuse à
proximité des bouches d’air de combustion. Le fait
de laisser des matières corrosives se mélanger à
l’air de combustion risque de réduire le cycle de vie
de l’appareil de chauffage et de compromettre son
fonctionnement.

For outdoor installations, exhaust venting consid-
erations will determine the placement of the heater, see
Section 2.3.4.
