SAFETY DEVICES

Overheat Switch:
This device automatically cuts the gas off if the heater exceeds a predetermined temperature. This is normally
caused by an obstruction in front of the louvres, or a blocked fan filter.
If this switch operates, turn the unit off, remove the obstruction (clean filters) and let the unit cool off before re-
operating.
Two Fusible Links
Backs up the overheat switch. If a fusible link cuts the unit off, a service call by an authorised person is
required to replace the link.
Flame Failure Device
If the flame goes out during operation this device cuts the unit off (lockout). To reset, turn the unit off, then on
again.
Fan Delay
Turns the fan on and off automatically when the heat exchanger warms up and when it cools down. This helps
to prevent cold draughts and maximises efficiency.
