CONSUMER INFORMATION AND SAFETY
WARNING
The U.S. Consumer Product Safety Commission warns that carbon monoxide is an "invisible killer". Carbon monoxide
is a colorless and odorless gas.
1. Carbon monoxide is produced by burning fuel, including natural gas and propane.
2. Proper installation, operation and maintenance of fuel-burning appliances in the home is the most important factor in reducing
carbon monoxide poisoning.
3. Be sure that fuel burning appliances such as heaters are installed by professionals according to manufacturer's instructions and codes.
4. Always follow the manufacturer's directions for safe operation.
5. Have the heating system (including vents) inspected and serviced annually by a trained service technician.
6. Examine vents regularly for improper connections, visible cracks, rust or stains.
7. Install battery-operated carbon monoxide alarms. The alarms should be certified to the requirements of the most recent UL, IAS,
CSA and IAPMO standard for carbon monoxide alarms. Test carbon monoxide alarms regularly and replace dead batteries.
WARNING
The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous.
See below for water temperature guidelines before setting temperature.
1. Spa or hot tub water temperatures should never exceed 40° C. A temperature of 37° C. is considered safe for a healthy adult.
Special caution is suggested for young children. Prolonged immersion in hot water can induce hyperthermia.
2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness
and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 37° C. can cause fetal damage during the first three months of pregnancy
(resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick to the 37° C. maximum rule.
4. Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer. Spa or hot tub
thermostats may err in regulating water temperatures by as much as -15° C.
5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their
physician's advice before using spas or hot tubs.
6. Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use spas
or hot tubs.

THIS PRODUCT MUST BE INSTALLED AND SERVICED BY A PROFESSIONAL SERVICE TECHNICIAN, QUALIFIED IN POOL
HEATER INSTALLATION.
Pentair strongly recommends that all vents, pipes and exhaust systems be initially and periodically tested for proper operation. This
testing can be accomplished by using a hand-held carbon monoxide meter and/or by consulting with a gas professional.
Pool heaters must be used in conjunction with carbon monoxide detectors installed near the pool heater. The carbon monoxide
detectors must be periodically inspected for proper operation so as to insure continued safety. Broken or malfunctioning carbon
monoxide detectors must be replaced immediately.
HEATER DESCRIPTION
Figure 1 is a diagram of the heater showing how it operates. Precisely
matched orifice plates meter the air and gas into the mixer. The blower
draws the air and gas through the mixer and forces it into the burner’s
flame holder. A sealed heat exchanger surrounds the flame holder,
discharging exhaust gases out the flue.
Five (5) cm PVC water piping connects directly to the manifold/
header on the heat exchanger using 5 cm PVC slip unions provided
with the heater. The outer manifold remains cool; no heat sinks are
required. A thermal regulator and an internal bypass regulate the water
flow through the heat exchanger to maintain the correct outlet
temperature. The heater operator control panel board assembly is
located on top of the heater.
SEQUENCE OF OPERATION
An electronic temperature sensing thermistor in the manifold adapter inlet controls the heater operation. When the inlet
water temperature drops below the temperature set on the operating control, the burner controller supplies power to
the combustion air blower through a series of safety interlocks. The interlocks consist of:
• the pressure switch (PS), which senses that the pump is running,
• the high limit switch (HLS), which opens if the heat exchanger outlet temperature goes above 53° C (127° F), and
• the air flow switch (AFS), which senses the pressure drop across the air metering orifice,
• the automatic gas shut-off (AGS) switch, which opens if the heat exchanger outlet temperature goes above 60° C (140° F).
• the stack flue sensor (SFS), which shuts down the heater if the flue gas temperature reaches 249° C (480° F).
The air flow switch (AFS) senses the pressure drop across the air metering orifice. As soon as there is sufficient air flow,
the AFS closes, closing the circuit to the hot surface igniter (HSI), which ignites the fuel mixture. On a call for heat, the
blower and HSI are energized. In about 20 seconds, the gas valve opens and ignition occurs. The HSI then switches to a
sensing mode and monitors the flame.
The heater is equipped with a digital operating control that enables the user to pre-set the desired pool and spa water
temperatures. The control enables the user to select between pool and spa heating, and features a digital display that
indicates the water temperature.
PUTTINGTHE HEATER INTO SERVICE
If the heater is installed below the level of the pool, or more than 0.6 meters (2 feet) above pool level, the pressure switch
setting should be adjusted. See “WATER PRESSURE SWITCH” in the “SAFETY CONTROLS Section” (page 32) and
the “CAUTION” under “BELOW POOL INSTALLATION Section” (page 12).
Before putting the heater into service for the first time, follow the instructions under “BEFORE START-UP” (page 30) in
the front of this manual. Check for proper operation of the heater by following the steps under “OPERATION
INSTRUCTIONS.”
Damage to equipment caused by improper installation or repair will void the warranty.

PLUMBING CONNECTIONS
The MasterTemp heater has the unique capability of direct
schedule 40 PVC plumbing connections. A set of bulkhead
fittings is included with the MasterTemp to insure conformity
with Pentair’s recommended PVC plumbing procedure. Other
plumbing connections can be used. See Figure 3 for plumbing
connections.
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.
VALVES
When any equipment is located below the surface of the pool or spa, valves should be placed in the circulation piping
system to isolate the equipment from the pool or spa. Check valves are recommended to prevent back-siphoning. Back-
siphoning is most likely to occur when the pump stops, creating a pressure-suction differential. Do NOT sanitize the pool
by putting chlorine tablets or sticks into the skimmer(s). When the pump is off, this will cause a high concentration of
chlorine to enter the heater, which could cause corrosion damage to the heat exchanger.
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.
MANUAL BY-PASS ( WATER FLOW RATE)
Where the water flow rate exceeds the maximum 454 LPM, a manual
bypass should be installed and adjusted. After installing the valve, adjust
the valve to bring the flow rate within the acceptable range. Then remove
the valve handle or lock it in place to avoid tampering. See Figure 4.

WATER CONNECTIONS
The heater requires proper water flow and pressure for its
operation. See Figure 5 for the recommended installation. The
filter pump discharges to the filter, the filter discharges to the
heater, and the heater discharges directly to the pool or spa.
A manual bypass valve should be installed across the heater
when the pump flow exceeds 454 LPM (120 GPM). See
“WATER FLOW RATE” on page 11 - Table 1 for setting of
the manual by-pass valve.
Make sure that the outlet plumbing from the heater contains
no shut-off valves or other flow restrictions that could prevent
flow through the heater (except for below pool as noted below,
or winterizing valves where needed). To switch flow between
the pool and spa, use a diverter valve. Do not use any valve
that can shut off the flow. Do not use a shut-off valve to
isolate the heater unless it is below the level of the pool or spa.
Install the chemical feeder downstream of the heater. Install
a chemical resistant one-way check valve between the heater
and the chemical feeder to prevent back-siphoning through the heater when the pump is off.
NOTICE: If the heater is plumbed in backwards, it will cycle continuously. Make sure piping from filter is not reversed
when installing heater.
Connect the heater directly to 5 cm PVC pipe, using the integral unions provided. Heat sinks are not required. The low
thermal mass of the heater will prevent overheating of the piping connected to the pump even if the heater shuts down
unexpectedly.
Occasionally a two-speed pump will not develop enough pressure on the low speed to operate the heater. In this case, run
the pump at high speed only to operate the heater. If this does not solve the problem, do not try to run the heater. Instead,
correct the installation.
Do not operate the heater while an automatic pool cleaner is also operating. If the circulation pump suction is plugged (for
example by leaves), there may not be adequate flow to the heater. Do not rely on the pressure switch in this case.
Local codes may require the installation of a pressure relief valve (PRV), see page 43 for “PRESSURE
RELIEF INSTRUCTIONS”.
BELOW POOL INSTALLATION
If the heater is below water level, the pressure switch must be adjusted. This adjustment must be done by a qualified
service technician.
See following CAUTION before installation.
CAUTION
BELOW OR ABOVE POOL INSTALLATION
The water pressure switch is set in the factory at 21 kPa (± 5 kPa). This setting is for a heater installed at pool level. If
the heater is to be installed more than 0.3 m above or below, the water pressure switch must be adjusted by a
qualified service technician. See page 32, Figure 22.
FLOW SWITCH
If the heater is installed more than 1.5 m above the pool or more than 1.2 m 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.

GAS CONNECTIONS
GAS LINE INSTALLATIONS
The gas supply must be installed in accordance with the Gas Installation Code, AS/NZS 5601.1, as applicable and all applicable local
codes.
Before installing the gas line, be sure to check which gas the heater has been designed to burn. This is important because
different types of gas require different gas pipe sizes. The rating plate on the heater will indicate which gas the heater is
designed to burn. Table 2 below shows the recommended gas inlet pipe sizes required for the distance from the gas meter to
the heater. The table is for natural gas at a specific gravity of .65 and propane at a specific gravity of 1.55.
When sizing gas lines, calculate 0.9 additional meters of straight pipe for every elbow used. When installing the gas line, avoid
getting dirt, grease or other foreign material in the pipe as this may cause damage to the gas valve, which may result in heater failure.
The gas meter should be checked to make sure that it will supply enough gas to the heater and any other appliances that may
be used on the same meter. Insufficient gas supply will cause the heater to operate below its designed performance or not at
all. The gas line from the meter will usually be of a larger size than the gas valve supplied with the heater. Therefore a
reduction of the connecting gas pipe will be necessary. Make this reduction as close to the heater as possible. Gas supply
companies are increasingly supplying natural gas to new installations with 2.75 kPa; this means if the gas pressure is not
adjusted to the correct working pressure, the heater will be over gassed and cause serious damage within minutes. This
damage is not covered under the heater warranty.
Install a manual shut-off valve that conforms with Type 1 or Type 2 as per AG201 and/or AS4617 standards, and a sediment
trap/drip leg and union located outside the heater panels, see Figure 6. Do not use a restrictive gas cock.
The heater and any other gas appliances must be disconnected from the gas supply piping system during any pressure testing
on that system, (greater than 6.0 kPa). The heater and its gas connection must be leak tested before placing the heater in
operation. Do not use flame to test the gas line. Use soapy water or another nonflammable method.
NOTE
A manual main shut-off valve must be installed externally to the heater.
WARNING
DO NOT INSTALL THE GAS LINE UNION INSIDE THE HEATER CABINET. THIS WILL VOID YOUR WARRANTY.
GAS PIPE SIZING
SEDIMENTTRAP/DRIP LEG
Install a sediment trap/drip leg and union located outside the
heater panels in accordance with National code
requirements. Do not use a restrictive gas cock. The sediment
trap/drip leg shall be either a tee fitting with a capped nipple
in the bottom outlet which can be removed for cleaning, as
illustrated in Figure 6, or an other device recognized as an
effective sediment trap/drip leg. All gas piping should be
tested after installation in accordance with local codes.

TESTING GAS LEAKS AND GAS PRESSURE
Table 3.
Before operating the heater, the heater and its gas connections must be leak tested. Do NOT use an open flame to test
for leaks. Test all gas connections for leaks with soapy water.
The gas valve must be completely disconnected from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 6.0 kPa (.87 psig).
TESTING THE GAS PRESSURE THROUGH THE COMBINATION GAS CONTROL VALVE
WARNING
Risk of fire and explosion. Alteration, service, or maintenance of the Combination Gas Control Valve can lead to fire or
explosion, causing loss of life, personal injury, and/or property damage. DO NOT ATTEMPT TO ADJUST THE GAS CONTROL
VALVE.
These instructions are for the use of qualified service technicians only!
1. Shut off the gas supply to the heater.
2. Loosen the small screw inside the pressure tap as shown in Figure 7.
3. Connect the manometer hose.
4. Open the gas supply to the heater.
5. Turn on the heater.
6. Take the gas pressure reading.
7. Turn off the heater.
8. Shut off the gas supply to the heater.
9. Disconnect the manometer hose.
10. Tighten the small screw inside the pressure tap.
11. Open the gas supply to the heater.

RESUMING OPERATION.
EXCESSIVE CARBON MONOXIDE EXPOSURE CAN CAUSE BRAIN DAMAGE OR DEATH.
WARNING
Risk of explosion if a unit burning propane gas is installed in a pit or other low spot. Propane is heavier than air. Do not
install the heater using propane in pits or other locations where gas might collect. Consult your local building code officials to
determine installation requirements and specific installation restrictions of the heater relative to propane storage tanks and
filling equipment. Installation must meet the requirements for the Standard for the Storage and Handling of Liquid Petroleum
Gases. Consult local codes and fire protection authorities about specific installation restrictions.
Locate the heater in an open, unroofed area and on a level surface
that is protected from drainage or run-off. Install the heater in an
area where leaves or other debris will not collect on or around the
heater.
It is recommended that a non-combustible base be a platform under
the heater constructed of hollow masonry blocks, not less than
100 millimeters (mm) thick (laid with ends unsealed and joints
matched for air circulation). Cover blocks with 0.75 mm (min.)
galvanized sheet metal, see Figure 8.

VERTICAL VENTING
(See Figures 12 and 14)
Vent the heater vertically in a system in accordance with AS/NZS 5601.1 and
local codes. Double-wall vent connector is recommended; however single-wall
pipe is allowed in some circumstances. Consult your local code official for detailed
information. Do not use a draft hood with this heater.
To connect a double wall metal gas vent to the heater, order the appropriate
Metal Flue Collar from the chart below:
1. See Table 6 to determine allowable vent sizes for your heater.
NOTICE: Table 6 is for installations in which the total lateral vent length (that is, the horizontal distance from
the flue collar to the main vertical portion of the vent) is less than half the total vent height (the vertical
distance from the flue collar to the vent termination) and which have three or less elbows in the system. For
vent lenghts greater than 16 m (52.5 ft), only one elbow is allowed. Please see Table 6a below for details.

4. Install vent pipe so that it can expand and contract freely as the temperature changes. Support the vent pipe according
to applicable codes and the vent manufacturer’s instructions. Pipe support must allow the vent pipe free movement
out and back, from side to side, or up and down as necessary, without putting a strain on the heater or vent body. Slope
horizontal pipe down to condensate trap at least 2 cm per meter (1/4 in per foot). Install approved condensate drains
at low points where condensate might collect. Plumb condensate drains to a drain through hard piping or high temperature
tubing such as silicone rubber or EPDM rubber – do not use vinyl or other low temperature tubing. Follow drain
manufacturer’s installation instructions.
