Installation & Operation Manual
If freeze protection is not provided for the system, a low ambient
temperature alarm is recommended for the equipment room.
Damage to the pool heater by freezing is non-warrantable.
1. Pump Operation - MOST IMPORTANT - This pool heater
is designed for continuous operation of the filter system
pump when the burners are firing. If the system pump does
not run continuously, an interlock mechanism should be
provided to disable when/if the system pump turns off. The
constant flow of warm pool water can help prevent freezing.
2. Anytime the temperature measured at the sensor drops
below 45°F, the temperature control turns on the pump to
circulate the water, if the pump option is installed.
3. Location - Indoor pool heaters must be located in a room
having a temperature safely above freezing [32°F(0°C)].
4. Outdoor Pool Heater Installation - Use extreme caution
to prevent freezing. A snow screen should be installed to
prevent snow and ice accumulation around the pool heater
or its venting system.
5. Shut-Down and Draining - If for any reason, the pool heater
is to be shut off, the following precautionary measures must
be taken:
a. Shut off gas supply;
b. Shut off water supply;
c. Shut off electrical supply;
d. Drain the pool heater completely. Remove the
threaded drain plugs from the inlet and outlet sides
of the front header on the heat exchanger (see FIG.’s
4-1 and 4-2). Blow all water out of the heat
exchanger. Leave drains open until Spring.
e. Drain pump and piping.
Check thermostat circuit(s)
1. Disconnect the two external wires connected to the enable
terminals on the connection board.
2. Connect a voltmeter across these two incoming wires.
Close each thermostat, and relay in the external circuit
one at a time and check the voltmeter reading across the
incoming wires.
3. There should NEVER be a voltage reading.
4. If a voltage does occur under any condition, check and
correct the external wiring.
5. Once the external thermostat circuit wiring is checked and
corrected if necessary, reconnect the external thermostat
circuit wires to the connection board. Allow the pool heater
to cycle.
Check vent and air piping
Inspect vent piping and air piping for signs of deterioration
from corrosion, physical damage or sagging. Verify air piping
and vent piping are intact and correctly installed per this
manual.
Placing the pool heater in operation
Pool heater operational checks
1. Turn the pool heater main power switch to the “ON”
position.
2. Verify operation of the SMART SYSTEM control
module and Operator Interface.
3. Program the adjustable points from the Operator
Interface.
4. Push the reset for the low water cutoff (if equipped).
5. Ensure that flow requirements and approximate
temperature rises shown in Table 4B on page 35 are met.
Verify by checking rises while the unit is at 100% of rated
input.
6. Install a manometer on the gas supply to the pool heater and
verify minimum gas supply pressure as the burner fires at
100% of rated input.
7. Verify operation of safeties as necessary (low water
cutoff, high limit, gas pressure, etc.,).
8. Verify that all adjustable points in the Operator
Interface are set as required.
9. Once the pool heater analysis is complete, test the safety
shutoff device by turning the manual shutoff valve to the OFF
position and ensuring that the pool heater shuts down and
registers an alarm. Open the manual shutoff valve and reset
the control.
10. Place the pool heater back into normal operation.
Pool heater operation
11. The pool heater should begin the start-up process for the
sequence of operation.
12. The pool heater will ignite at the proper ignition speed and
will stage to meet the system demand.
13. Ensure that inlet water temperature does not fall below
the specified minimum for the pool heater.
14. Based on system demand, pool heaters may run for an
extended period of time at a reduced rate of input to
maximize efficiency.
15. As system demand is satisfied, the burner will cycle off
and the combustion air blower will run for a post
purge operation before the pool heater shuts down.
Start the pool heater
Read and follow the Lighting Instructions in FIG. 6-2, on page
47.
If pool heater does not start correctly
1. Check for loose connections, blown fuse or service switch
off?
2. Is the unit in lockout? Is the pool heater outlet temperature
exceeding 200°F (93.3°C)?
3. Is the thermostat set below pool water temperature?
4. Is gas turned on at meter or pool heater?
5. Is incoming gas pressure less than 4.5" water column?
If none of the above corrects the problem, refer to the
Troubleshooting Section of the Copper-fin
2
Service Manual.
The venting system must be installed so that
it will prevent flue gas spillage and carbon
monoxide emissions, which will result in
severe personal injury or death.
