Specifications

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,
terminating outside the building. The vent must
terminate at least two (2) feet (0.6 m) above the highest
point of the roof or other object that is within ten (10)
feet (3.0 m) of the vent termination. The vent pipe must
have a listed vent cap which allows a full equivalent
opening for ue products, see Figure 5. The top of the
vent cap must be at least ve 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 as specied 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 its own vent
temperature limit switch. All vent limit switches must
be wired in series so as to prevent any appliance from
ring 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 Model LRZ electronic 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 Model LRZ electronic
heater. Replace any parts that are not in good and
serviceable condition with new parts before completing
the pool heater installation.
Section 4. Gas Connections
4.1 Gas Supply and Piping
Review the following general instructions before
continuing the installation.
Important:
Do not install LP gas units indoors.
The Legacy Model LRZ 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 designed to use the
type of gas being supplied. DO NOT ATTEMPT
TO CONVERT THIS HEATER FOR USE WITH
ANY OTHER TYPE OF FUEL.

AVERTISSEMENT
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 accor-
dance 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 Model LRZ electronic heaters, as shipped
from the factory, are certied to operate within
the altitude range indicated on the rating plate.
If a eld 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 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 ll out the altitude conversion label, included in
the kit. Apply the label next to the original rating
plate.
Permanent damage to the gas valve will occur if
the following procedures are not followed.
CAUTION
Vous endommagerez la soupape de gaz si vous
ne respectez pas les procédures suivantes.
