 Pool/Spa Heater 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 modi

fi

 cation et selon les exigences fournies 

par le manufacturier.

The applicable codes, standards and Jandy Pool 

Products, 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 ef

fi

 cient 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), depend-

ing upon the model of your heater. (See Figure 

6.) See vent installation section for important 

information on selecting proper pipe size.

Section 3.  Venting

3.1 Combustion 

Air 

Supply

The heater location must provide suf

fi

 cient 

air supply for proper combustion and ventilation of 

the surrounding area as outlined in the latest edition 

of ANSI standard Z223.1 (NFPA 54) or in Canada, 

CAN/CSA-B149.1, and any local codes that may be 

applicable.

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 

fl

 oor. All indoor installations 

must have openings to outside air for combustion, 

ventilation, and dilution of 

fl

 ue gases from inside the 

building. See Figure 7 and Table 3. Jandy Pool Prod-

ucts, 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. 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 open-

ing 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 

fl

 ow area for 

each 2000 BTU/h (0.6 kW). These requirements are 

summarized in Table 3. Note that the areas speci

fi

 ed 

are net free areas and should be increased when the 

openings are covered by screens, louvers, grills or oth-

er protective covers. See Figure 8 and Table 3 notes.

Note

    In Canada, follow Canadian Standard, CAN/

CSA-B149.1 or local codes.
