   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.

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.
