CHAPTER 4
OPERATION
The initial start of your HURRICANE heater must be done by an authorized service
person. Be sure that all components have been properly installed according to the
instructions laid out in this manual before the initial start.
4.1 STARTING THE HEATER
The major steps in starting the heater are as follows:
1.
Turn on the ON/Off control switch, located on the remote indicator panel.
2.
Turn up the zone thermostat to a setting higher than room temperature.
3.
Start the heater by switching the service switch to ON. This switch is located on the side of the
electronic control box.
4.2 SIGNS OF NORMAL OPERATION
When the heater is operating normally:
•
The ignitor will glow and the combustion air intake fan and the circulating pump
begin to run. Whenever the pump is running, the green LED at the bottom of the
LED display will be on.
•
A few seconds later, the fuel pump starts delivering fuel to the regulator, the
compressor turns ON, the fuel valve opens, and fuel is drawn to the air aspirating
nozzle. The fuel is atomized and sprayed into the combustion chamber to start
combustion.
After the ignition period (about 10 seconds), the ignitor shuts OFF, and the burner continues to operate.
The heater will operate until all the zone thermostats are satisfied, or until the heater reaches its normal
water operating temperature of 180°F. Once the normal operating temperature is reached, the burner
itself will cycle off and the combustion fan will operate for an additional two minutes to purge the
burner. If a zone thermostat, domestic water heater aquastat, or engine heat exchanger aquastat is not
satisfied, the circulating pump will continue to operate. If a thermostat cannot be satisfied by the
residual heat in the system, and the water temperature drops, the burner will restart and cycle until all
thermostats are satisfied. Once all themostats are satisfied, the heater will go through
the two minute purge, and the circulating pump will cease. The circulating pump
will operate if the remote switch and any zone thermostat or the domestic water
aquastat (W-W) are on. The circulating pump will be activated
