CABINET HEATER
1.3
Heater Operation (On/Off)
Once the heater has initially been switched on using the remote controls, the operation of the heater becomes automatic
under the control of the remote time/temperature controls (as fitted on site) and the safety devices.
When the external controls call for heat, the control box of the fully automatic burner checks that all systems are in a
safe and ready position, and then initiates a start sequence. It then constantly monitors safe operation of the burner
(see Section 2.2 & 2.3 for details).
When the heat exchanger has been sufficiently heated, the built in fan thermostat turns on the main fan(s) and warm
air is distributed from the top of the heater.
Note:
On horizontally mounted heaters, High Flow heaters, heaters fitted with high/low or modulating burners and
some fully ducted heaters, the fan will come on during the burner firing cycle and not wait for the temperature rise. This
is to ensure that there is always a proper operation of the heater under all possible conditions.
At the close down of the external controls, the burner shuts off and the main fan(s) continue to run until the fan
thermostat detects a drop in leaving air temperature, sufficient to turn it off. The heater is then at rest until the beginning
of the next cycle.
If for any reason the main fan should fail or the air flow through the heater is reduced, then the built in limit thermostat
will cause the burner to go to safety shut down lockout. This condition will remain until the fault is corrected and the
manual red reset button is operated at the limit thermostat.
1.2.1
Heater Operation (High/Low)
For burners which are capable of High/Low operation, a two stage thermostat will be required to be installed on site to
alow the burner to operate On/Off and High/Low dependant upon conditions (see 4.3.1.1 for details)
1.2.2
Heater Operation (Fully Modulating)
For gas burners only which are capable of Fully Modulating operation the burner comes complete with a temperature
control system. The sensor of this system needs to be installed on site (see 4.3.1.2) to allow the burner to vary the heat
input to maintain a constant control temperature.
WARNING
The main electrical isolator should only be used in an emergency and for servicing.
It should never be used for closing down the burner, as this switches off the main fan prematurely
and may damage the heat exchanger, invalidating the warranty and causing a potential fire hazard.
