 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 

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.

TEST THE WATER HEATER AFTER INSTALLATION 

• 

The operation of the water heater must be thoroughly checked by the 
installer. 

• 

The burner flame must light smoothly and quickly from the hot surface 
igniter and must go out quietly and completely. 

• 

The burner flame must be stable, although slight lifting at the front edge of 
the burner is acceptable when the burner is cold.
