LIGHTING THE WATER HEATER

DIAGNOSTIC FEATURES OF HOT SURFACE IGNITION CONTROL Warning: The removal of the access covers will expose 240 V wiring. They must only be removed by an authorised or service person only.

The water heater incorporates an electronic control module. This is located inside the access cover of an indoor model and to the right of the access cover inside the air duct on an outdoor model (refer to installation diagrams on pages 22 and 23).

An LED light on the module will flash once when power is switched on to the water heater. In the event of a fault occurring in or affecting the Hot Surface Ignition system, the system will enter “lock out” and the LED will emit a series of flashes diagnosing the fault. There will be a 2 second interval between each group of flashes.
