Avoid long horizontal runs of the vent pipe, and
90° elbows, reductions and restrictions. Horizontal runs
should have at least a 1/4 inch rise per foot (20mm
per meter) in the direction of flow.
Avoid terminating heater vents near air condition-
ing or air supply fans. The fans can pick up exhaust
flue products from the heater and return them inside
the building, creating a possible health hazard.
Do not locate the vent terminal where flue
products could strike against building materials and
cause degradation.
Vent opening should be well away from trees or
other obstructions that would prevent free air flow to
and from vent terminal. Do not terminate the vent
under decks, stairways, or car ports.
Be sure to support all venting so that connections
will not separate and so that the weight of the vent
pipe does not rest on the heater draft hood. All con-
nections should be made with rustproof sheet metal
screws. Do not weld or fasten the vent pipe to the
heater draft hood. The draft hood and heater top must
be easily removable for normal heater service and
inspection.
The draft hood outlet is to be connected to an
unobstructed vent pipe of the same diameter, terminat-
ing outside the building. The vent must terminate at
least two (2) feet (0.61 m) above the highest point of
the roof or other object that is within ten (10) feet
(3.05 m) of the vent termination. The vent pipe must
have a listed vent cap which allows a full equivalent
opening for flue products (see Figure 4). The top of
the vent cap must be at least five feet in vertical height
above the drafthood outlet.
Type “B” double wall or equivalent vent pipe is
recommended. However, single wall metal vent pipe
may be used as specified in the latest edition of the
National Fuel Gas Code ANSI Z223.1 or in Canada
CAN/CSA-B149.1
IMPORTANT NOTE: Do not use sheet metal screws
at the snap lock joints of Type B gas vents.
When venting multiple appliances through one
common duct, each appliance must have it’s own vent
temperature limit switch. All vent limit switches must
be wired in series so as to prevent any appliance from
firing in the event of a blocked vent. Refer to ANSI
Z223.1 or, in Canada, to CAN/CSA-B149.1 for more
information on multiple venting.
SECTION 4.
Gas Connections
4.1 Gas Supply and Piping
Review the following general instructions before
continuing the installation.
WARNING
The Lite2 pool and spa heaters are designed for use
with either natural gas or LP gas. Check the rating
plate on the inner panel to be sure that the heater is
configured to use the type of gas being supplied.
DO
NOT ATTEMPT TO CONVERT THIS HEATER FOR
USE WITH ANY OTHER TYPE OF FUEL.
AVERTISSEMENT
Les appareils de chauffage à Lite 2 pour piscines et
cuves thermales sont conçus pour être utilisés avec
du gaz naturel ou du gaz de pétrole liquéfié (GPL).
Vérifiez l’information inscrite sur la plaque
signalétique du panneau intérieur pour vous assurer
que l’appareil est configuré pour le type de gaz
fourni.
NE PAS ESSAYER DE CONVERTIR CET
APPAREIL À UN AUTRE TYPE DE GAZ.
1. Gas piping installation must be in accordance
with the latest edition of ANSI Z223.1 and all
local codes. In Canada, the installation must be
in accordance with CAN/CSA-B149.1 and all
local codes that apply.
2. Check the gas supply to be sure that it is the
same as the gas indicated on the heater’s rating
plate. Jandy Lite2 LD heaters, as shipped from
the factory, are certified to operate within the
altitude range indicated on the rating plate. If a
field conversion to a different altitude range
should be necessary, manifold kits are available
for changing the altitude range of the heater. See
Table 1 in section 1.7.1 of this manual to deter-
mine the correct altitude designation for your
heater. Refer to Section 11 “Parts List” to order
the correct part number of the manifold kit
needed. When changing the altitude range of the
heater, be sure to fill out the altitude conversion
label, included in the kit. Apply the label on the
inner panel of the heater, next to the original
rating plate.
CAUTION
Permanent damage to the gas valve will occur if the
following procedures are not followed.
ATTENTION
Vous endommagerez la soupape de gaz si vous ne
respectez pas les procédures suivantes.
3. Use the figures in Table 4 to size the gas inlet
piping from the gas meter to the heater. Check
all local codes for compliance before installing
the heater.
