Installation and Operation Manual
Avoid terminating heater vents near air condi-
tioning 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 connec-
tions will not separate and so that the weight of the
vent pipe does not rest on the heater draft hood. All
connections 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, termi-
nating 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 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 5. The top of the vent cap
must be at least five feet in vertical height above the
draft hood outlet.
Type “B” double wall or equivalent vent pipe is
recommended for the entire venting system. However,
single wall metal vent pipe may be used within the
structure 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.
3.2.3 inspection and Replacement of
existing vent System with New
components
If the Legacy is being installed to replace an
existing pool heater, it is recommended that a new
appropriate venting system be installed with the new
heater. However, if an existing venting system must be
used, be sure to carefully inspect the venting system to
ensure that it is in good condition and continues to be
appropriate for the Legacy heater. Replace any parts
that are not in good and serviceable condition with
new parts before completing the pool heater installa-
tion.

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. Legacy 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 chang-
ing the altitude range of the heater. See Table 1
in section 1.7.1 of this manual to determine 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 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.
