2.0 User Instructions
2.1 Controls
The main user controls are the 2 rocker switches on the left hand side of the control panel.
The three position rocker switch at the top is marked ‘Fan Only’, ‘Off’ and ‘Heating On’.
At the ‘Fan Only’ position the heater provides summer time ventilation by delivering
air at the ambient temperature with the burner switched off.
At the ‘Off’ position the heater will not operate.
When the switch is positioned at ‘Heating On’ the heater will fire and deliver warm air
automatically controlled by the fan stat and the room thermostat.
The sequence of firing will be as follows. The burner will go through its ignition cycle
and fire. When the combustion chamber has been sufficiently heated the fan stat will
automatically start the main air fan and discharge warm air through the swivel hoods
or ducting.
When the heater is shutdown either via the room stat or any other controls the burner
will stop firing although the main air fan will continue to operate until the combustion
chamber has been properly cooled down. At which point the fan stat will shut the main
air fan down.
Because of residual heat within the combustion chamber the fan stat may re-start the
main air fan until sufficient cooling of the combustion chamber has taken place.
When the burner is firing the indicator lamp on the panel will be illuminated.
The 2 position rocker switch is marked ‘Automatic’ and ‘Manual’.
At the ‘Automatic’, position the heater will be operated automatically via the time
clock.
When positioned at ‘Manual’ the end user controls the time of operation.
NOTE:WHEN FIRING ORWHEN HOT,THE HEATER MUST NEVER BE SWITCHED
OFF AT THE MAINS SUPPLY.
This is to allow proper cooling of the combustion chamber thus preventing tripping out
on the high limit stat and heat damage to the combustion chamber.
If the high limit fan stat should trip out wait until the combustion chamber has cooled
sufficiently before pressing the red reset button on the fan stat. If the high limit continues
to trip, switch the heater to ‘off’ and contact the Warmflow Service Department.
If the fan motor draws more current than the set limit the overload relay can be reset
by pressing the red button in the control panel.
If the relay continues to trip contact the Warmflow Service Department.
