NOTICE: When the heater is mounted more
than 1.5M (5 ft.) above or 1.2M (4 ft.) below
the deck level, a Pressure Switch is no
longer adequate. A Flow Switch must be
installed instead.
NOTICE: Heater operation with incorrect
Pressure Switch setting may cause
operation with no water ow. Operation
of the heater without sufcient water ow
may cause severe damage and will void the
warranty.
HIGH LIMITS
A “High Limit”, is a safety device that opens the electrical circuit and shuts off the heater based
on a water temperature set point within the “High Limit Device”. The Turbotemp 125 heater has
two (2) high limit devices which are located on the main inlet / outlet header (see page 43 item
6).
OPERATION OF IGNITION MODULE
The Ignition Module (see Figure 7), is
microprocessor based and operates
on 24VAC supplied by the transformer.
The control utilizes a microprocessor to
continually and safely monitor, analyze, and
control the proper operation of the gas ame
holder. The module with the presence of the
ame sensor, using ame rectication.
TEMPERATURE SETTING
The heater temperature setting is factory set at 25.6° C (78° F). for pool mode and 37.8° C (100°
F). for the spa mode. To adjust the set temperature, use the up and down arrows to set the pool/
spa thermostats to a minimum temperature of 18.3° C (65° F.), or a maximum of 40° C (104° F).
If you desire to heat only one body of water, the thermostat is capable of an off mode. As an
example, if you only wish to heat the spa and not the pool, simply depress and hold the pool
down arrow, and the thermostat will lower its setting to 18.3° C (65° F.) then go to an off mode.
Note: See below to change the heater’s factory set temperature settings.
ADJUST THE MAXIMUM TEMPERATURE SET POINT
1. Unbolt and remove the door panels (see Figure 8).
2. Access the control panel board on the underside of the top cover. Locate the yellow button
on the corner of the control board.
3. Push the Max. Temp. Set Point button on the back of the control board (see Figure 9).

Turbotemp 125 Pool and Spa Heater Installation and User’s Guide
Section 2: Installation Instructions
This product must be installed and serviced by a professional service technician, qualied
in pool heater installation. Waterco Limited 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. If not tted on the heater, installer must install any safety devices
according to the current local codes.
HEATER DESCRIPTION
Figure 10 shows a diagram of the heater and
how it operates. Precisely matched orice
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 ame holder. A
sealed heat exchanger surrounds the ame
holder, discharging exhaust gases out the ue.
5 cm (2”) PVC water piping connects directly
to the manifold/ header on the heat exchanger
using 4 cm (1.5”) 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 ow
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 55° C (131° F), and
•the air flow switch (AFS), which senses the pressure drop across the air metering orice,
•the automatic gas shut-off (AGS) switch, which opens if the heat exchanger outlet
temperature goes above 60° C (140° F).
•the inlet temperature control switch, which opens if the inlet temperature goes above 45°
C (110° F).
•the stack flue sensor (SFS), which shuts down the heater if the ue gas temperature
reaches 249° C (480° F).
The air ow switch (AFS) senses the pressure drop across the air metering orice. As soon as
there is sufcient air ow, 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 ame. 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.
PUTTING THE 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 3) and the “CAUTION” under “BELOW POOL
INSTALLATION Section” (page 8).
Before putting the heater into service for the rst time, follow the instructions under “BEFORE
START-UP” (page 1) in the front of this manual. Check for proper operation of the heater by
following the steps under, see page 11 “OPERATION INSTRUCTIONS.”
SPECIFICATIONS (DIMENSIONS IN CENTIMETERS AND INCHES)
These installation instructions are designed for use by qualied personnel only, trained especially
for installation of this type of heating equipment and related components. Some states require

PLUMBING CONNECTIONS
The Turbotemp 125 heater has the
capability of direct schedule 40 PVC
plumbing connections. A set of bulkhead
ttings is included with the Turbotemp
125 heater to insure conformity with
Waterco recommended PVC plumbing
procedure. Other plumbing connections
can be used. See Figure 12 for plumbing
connections.
WATER CONNECTIONS
The heater requires proper water ow
and pressure for its operation. See Figure
13 for the recommended installation. The
lter pump discharges to the lter, the
lter 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 ow exceeds 265 LPM (70 GPM). See “WATER FLOW RATE”
on page 8 - Table 1 for setting of the manual by-pass valve.
Ensure the outlet plumbing from the heater contains no shut - off valves or other ow restrictions
which may prevent ow through the heater (except for heaters installed below water surface
level as noted below, or winterising valves where required). To switch ow between the pool and
spa, use a diverter valve. Do not use any valve that can shut off the ow. 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.
Before operating the heater on a new
installation, turn on the circulation
pump and bleed all the air from the
lter using the air relief valve on top
of the lter. Water should ow 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 ensure all air is purged from the
heater.
!
CAUTION
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 ow to the heater.
Do not rely on the pressure switch in this case.
If local codes require the installation of a pressure relief valve (PRV), see page 35 for
“PRESSURE RELIEF VALVE INSTRUCTIONS”.
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.
MANUAL BY-PASS (WATER FLOW RATE)
Where the water ow rate exceeds the maximum
265 LPM, a manual bypass should be installed and
adjusted. After installing the valve, adjust the valve
to bring the ow rate within the acceptable range.
Then remove the valve handle or lock it in place to
avoid tampering. See Figure 14.
Exercise care when installing chemical feeders so as to not allow back siphoning of chemical
into the heater, lters 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”, between the feeder and heater.

BELOW POOL INSTALLATION
If the heater is below water level, the pressure switch must be adjusted. This adjustment must
be done by a qualied service technician. See following CAUTION before installation.
BELOW OR ABOVE POOL INSTALLATION
The WATER PRESSURE RELIEF VALVE SWITCH is set in the factory at 21 kPa (± 5
kPa) (3 ± 0.7 psi). This setting is for a heater installed at pool level. If the heater is to
be installed more than 0.3 m (1ft.) above or below, the water pressure switch must be
adjusted by a qualified service technician. See page 35 Figure 30.
!
CAUTION
FLOW SWITCH INSTALLATION
If the heater is installed more than 1.5 m above the pool or more than 1.2 m below the
pool level, which is beyond the limits of the heater’s pressure switch specification.
In this case, a flow switch must be installed in the heater. 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 as used for the water pressure switch.
GAS CONNECTIONS
GAS LINE INSTALLATIONS
The gas supply must be installed in accordance with the Gas Installation Code, AS/NZS.5601.1
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 specic gravity of .65 and propane at a specic 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. 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 15. 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 nonammable method.
NOTE
A manual main shut-off valve must be installed externally to the heater.
DO NOT INSTALL THE GAS LINE UNION INSIDE THE HEATER CABINET. THIS WILL VOID
YOUR WARRANTY.

nipple in the bottom outlet which can
be removed for cleaning, as shown in
Figure 15, or other device recognized as
an effective sediment trap. All gas piping
should be tested after installation in
accordance with current local codes.
TESTING GAS LEAKS AND GAS PRESSURE
THE TURBOTEMP HEATER IS INTENDED FOR INSTALLATION WITH A METERED GAS
PRESSURE REGULATOR. Before operating, 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.
TESTING THE GAS PRESSURE THROUGH THE COMBINATION GAS
CONTROL VALVE.
Risk of fire and explosion. Alteration, service, or maintenance of the Combination Gas
Control Valve can lead to re or explosion, causing loss of life, personal injury, and/or
property damage. DO NOT ATTEMPT TO ADJUST THE GAS CONTROL VALVE.

3. Attach the vent pipe to the metal Flue Collar
with sheet-metal screws.
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.
5. Use approved re stop for oor and ceiling
penetrations. Use approved thimble for
wall penetrations. Use an approved roof
ashing, roof jack, or roof thimble for all roof
penetrations. Do not ll the space around the
vent (that is, the clear air space in the thimble
or re stop) with insulation. The roof opening
must be located so that the vent is vertical.
6. Do not run the heater vent into a common
vent with any other appliance.
Risk of re or asphyxiation if vent is not assembled according to manufacturer’s instructions or
if vent parts from different manufacturers are mixed. Vent parts from different manufacturers
ARE NOT interchangeable. Mixing parts from more than one manufacturer may cause leaks
or damage to vent. When assembling a vent, pick one manufacturer and be sure that all vent
parts come from that manufacturer and are specied by the manufacturer for your system.
Follow manufacturer’s instructions, local code requirements and local code standards.
!
WARNING
Fire Hazard. Do not vent the heater directly into a masonry chimney. Installation into a
masonry chimney must use a chimney liner which must meet local code standards and all
local code requirements.
!
WARNING
Risk of fire, carbon monoxide poisoning, or asphyxiation. It is recommended to use a CO
Monitor and Fire Alarm in rooms that contain gas red appliances.
!
WARNING
NOTE
After installation, installer must check for correct and safe operation of the heater.
HORIZONTAL OR VERTICAL VENTING - USING SINGLE-WALL STAINLESS
GAS VENT (See Figures 26, 27 and 28)
Vent the heater either horizontally or vertically using an optional vent adapter of the 150 mm
(6 in) or 102 mm (4 in) special gas approved stainless steel vent pipes. Installation must be in
accordance with AS/NZS 5601.1 and/or local codes and ordinances. The heater, when installed,
must be electrically grounded and bonded in accordance with local codes. Do not use a draft
hood with this heater. Install the vent according to the vent manufacturer’s detailed instructions.
Note: Keep a 150 cm (6 in) minimum clearance between the vent pipe and combustible surfaces.
Follow the vent manufacturer’s instructions and code requirements. Do not place any insulating
materials around the vent or inside the required clear air space surrounding the vent. See Table
8 for maximum permissible vent lengths.
NOTE
The allowable vent runs for each vent pipe diameter are
different and can not be exceeded.
Each 90-degree elbow reduces the maximum horizontal vent
run by 3.6 m (12 feet) and each 45-degree elbow in the vent
run reduces the maximum vent run by 1.8 m (6 feet). See
Table 8 for the maximum vent lengths using 90° elbows.

slope down toward the outlet
at 2 cm to the meter (1/4 in / ft.)
to allow condensate to drain.
NOTE
It is recommended vent runs over 5.4 m (18 feet) may need to
be insulated to reduce condensation related problems and/
or the use of a condensate trap in the vent run close to the
heater may be necessary in certain installations such as cold
climates. Horizontal vents 1 m (3 feet) or less in length do not
require a condensate tee. Note: The Turbotemp heater is
suitable for through-the-wall venting.
Flue gases may escape into the dwelling with any cracks or loose joints in the vent pipe,
or improper vent installation. The vent pipe must be of a sealed-seam construction and for
operating temperatures less than 204° C (400°F). Vent pipe construction will be according to
local code standards, approved non-corrosive material, such as stainless steel. A condensate
trap may be needed. The use of “Approved” thimbles, roof jacks and/or side vent terminals are
required; and the proper clearances to combustible materials must be maintained in accordance
with type of vent pipe employed—in the absence of a clearance recommendation by the vent
pipe manufacturer, the requirements of the Uniform Mechanical Code should be met.
See page 14 for ventilation air requirements for the Turbotemp heater.
NOTE: After installation, installer must check for correct and safe operation of the heater.
