attempt to convert heater from one fuel totheother. Donot attempt to alterthe ratedinput or type of
gas by changingtheorifice. If itis necessary toconvert toa different typeof gas, consultyourPentair
dealer. Serious malfunction of the burner can occur which may result in loss of life.Any additions,
changes, or conversions required in order for the appliance to satisfactorily meet the application
needs must be made by a Pentair dealer or other qualified agency using factory specified and
approved parts. The heater is available for use with natural gas or LP (propane) gas only. It is not
designed to operate with any other fuels. Refer to the nameplate for the type of gas the heater is
equipped to use.
• Use heater only with the fuel for which it is designed.
• If a fuel conversionis necessary,refer this work to a qualifiedservice technician or gas supplier
before putting the heater into operation.
WARNING —
Risk of fire or explosion from flammable vapors.
Donotstoregasoline, cleaningfluids,varnishes,
paints, or othervolatile flammable liquids near heater or in the same room with heater.
WARNING —
Risk of explosion if unit is installed near propane gas storage.
Propane (LP) gas is heavier
than air. Consult local codes and fire protection authorities about specific installation requirements
andrestrictions. Locate the heater awayfrom propane gasstorage andfillingequipmentas specified
by the Standard for the Storage and Handling of Liquefied Petroleum Gases, CAN/CSA B149.2
(latest edition)or ANSI/NFPA58 (latest edition).
WARNING —
Risk of fire, carbon monoxide poisoning, or asphyxiation if exhaust venting system leaks.
Only qualified service technicians should attempt to service the heater, as leakage of exhaust
products or flammable gas may result from incorrect servicing.
WARNING —
Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly
when installing heater.
Do not use a drafthood with this heater, as the exhaust is under
pressure from the burner blower and a draft hood will allow exhaust fumes to blow into the room
housing the heater. The heater is supplied with an integral venting system for outdoor installation.
A vent conversion kit (See Page24 for Part Numbersfor ConversionKits) is available for installations
in enclosures (Canada) or indoors (U.S.). Use thespecifiedventing, and only the specifiedventing,
when heater isinstalled in an enclosure or indoors. In Canada, this pool heater can only beinstalled
outdoors or in an enclosurethat is not normallyoccupied and has no openings directly intooccupied
areas. See Page 20 for enclosure venting requirements.
CAUTION —
Label all wires prior to disconnection when servicing controls. Wiring errors can cause
improper and dangerous operation. Wiring errors can also destroy the control board.

CAUTION
Before operating the heater on a new installation, turn
on the circulation pump and bleed all the air from the
filter using the air relief valve on top of the filter. Water
should flow freely through the heater. Do not operate
the heater unless water in the pool/spa is at the proper
level. If a manual by-pass is installed, temporarily close it
to insure that all air is purged from the heater.

CAUTION
BELOW OR ABOVEPOOLINSTALLATION
The water pressure switch is set in the factory at 3.00 PSI (± 0.75 PSI). This setting is for a heater installed at pool level.
If the heater is to be installed more than 1’ above or below, the water pressure switch must be adjusted by a qualified
service technician. See page 35, Figure 29.
FLOWSWITCH
If the heater is installed more than 5’ above the pool or more than 4’below the pool level, you will be beyond the limits
of the pressure switch and a flow switch must be installed. Locate and install the flow switch externally on the outlet
piping from the heater, as close as possible to the heater. Connect the flow switch wires in place of the water
pressure switch wires.

CAUTION
Exercise care when installing chemical feeders so as to not allow back siphoning of chemical into the heater, filters
or pump. When chemical feeders are installed in the circulation of the piping system, make sure the feeder outlet line
is down stream of the heater, and is equipped with a positive seal noncorrosive “Check Valve”, (P/N R172288),
between the feeder and heater.
