Model LC (Australia) Pool and Spa Heater
Page 9
On propane heaters, if the pilot does not ignite
within 15 seconds, the system locks out and turns off
power to the whole system.
To check the lockout on the ignition control, turn
the gas valve knob OFF. Set the thermostat to call for
heat. Sparking occurs after a few seconds, but since
there is no supply gas, the pilot cannot light. Sparking
continues for about 15 seconds until lockout occurs
and the ignition control shuts down the system. To
reactivate the system, turn the thermostat to its lowest
setting, wait 10 seconds, then turn the thermostat to its
original setting.
1.
Turn the gas valve knob to ON.
2.
Replace the control compartment door.
3.
Position the rotary switch to ON and follow
the lighting instructions above.
3C-2. Filter Pump Operation
The filter pump must continue running for at
least 15 minutes after the heater shuts off to prevent
damage to the system piping.
3C-3. Shutdown
For a complete shutdown, turn the switch on the
control panel to OFF, turn off all electrical power to
the heater at the main junction box, and set the thermo-
stat to its lowest setting. Open the control compartment
door and turn the gas valve knob clockwise to OFF.
Turn any external gas valves OFF.
3D. Spring and Autumn Operation
During periods of cold but not freezing weather,
turn the temperature control counterclockwise to the
MIN setting. This will prevent damage, yet still permit
bringing the pool water back up to the desired tempera-
ture in the least amount of time.
In areas subject to only short freeze periods, turn
off the heater and run the filter pump continuously for
the length of the cold period.
If the pool is not going to be heated for a long
period, shut the heater off (see Section 3C-3).
3C. Lighting and Shutdown
3C-1. Lighting the Heater
Full lighting and shutdown instructions can also
be found attached to the inside of the control compart-
ment door.
To restart the heater in the Spring, have a profes-
sional service technician reassemble the heater as
follows:
WARNING
For your safety when starting the heater, keep
your head and face well away from the lower
firebox opening to prevent any risk of personal
injury.
Turn off all electrical power to the heater at the
main junction box. Open the control compartment door
and turn the gas valve OFF. Turn the rotary switch on
the temperature control panel OFF. WAIT FIVE
MINUTES BEFORE TRYING TO LIGHT THE
HEATER.
The LC (Australia) heater does not need manual
pilot lighting. It is done automatically by the ignition
control when the thermostat calls for heat.
1.
Turn the gas valve control knob counter-
clockwise to ON (Fig. 13).
2.
Replace the control compartment door.
3.
Turn on electrical power to the heater.
4.
Turn on the filter pump.
5.
Set the appropriate temperature control to the
desired setting, and turn the rotary switch to
that control. Until the water reaches a tempera-
ture of about 21°C, it is normal to have some
water accumulating in the base of the heater.
6.
Set the time clock if one is installed.
