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. Jandy Pool Products, Inc. does not recom-
mend 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 flow area for each 2000
BTU/h (0.6 kW). These requirements 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 5 and Table 3 notes).
NOTE: In Canada, follow Canadian Standard,
CAN/CSA-B149.1 or local codes.
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
qualified engineers.
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
corrosive material near combustion air
openings or in the room. Avoid locating dryer
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.
AVERTISSEMENT
N’entreposer aucun produit chimique, produit
nettoyant 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.
3.2 Vent Pipe Sizing and General
Installation
3.2.1 Outdoor Installations
For outdoor installations, exhaust venting consid-
erations will determine the placement of the heater
(See Section 2.3.4). 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 vertical 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
National Fuel Gas Code 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 condensation. In either case the result
can be release of combustion products to the
indoors. This can cause serious injury or death
by carbon monoxide poisoning or asphyxiation.
AVERTISSEMENT
Le diamètre des tuyaux de ventilation doit
répondre aux exigences du National Fuel Gas
Code 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 inadéquate et des
tuyaux trop gros risquent de provoquer une
condensation dans les tuyaux. Dans un cas
comme dans l’autre, des produits de
combustion 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
