OPERATION 

When the gas control knob  is  in  the  OFF  position 

( • ) there will be no gas flow into the gas section

of the unit.

By rotating the knob anti - clockwise through the 

ignition  position  (  �

·

)  the  integral  piezo  will 

operate  and  generate  a  spark  between  the 

electrode and the pilot head.  Simultaneously the 

pilot valve and the thermo - electric valve will be 

pushed  open,  allowing  gas  to  flow  into  the  gas 

section chamber and to the pilot head.  (The pilot 

should light; if not, repeat the operation) 

(Fig.1). 

After the pilot is lit (knob in PILOT position 

*

the  knob  can  be released  and  the  pilot  will  stay 

alight. Allow  15 seconds for the thermo - electric 

valve to energise before rotating the knob. 

By  rotating  the  control  knob  further  anti 

clockwise, the gas control side valve will gradually 

open; and on reaching the MAXIMUM position (�) 

(Fig.2) 

be  fully  open.  By  rotating  this  knob 

between maximum and minimum (  �-'  ) the 

gas rate to the burner can be varied. 

By turning on a hot water tap, the main gas valve 

(water diaphragm operated) will open and allow 

gas to the main burner. 

The water flow through the unit can be controlled 

by the water control knob situated beneath  the 

gas control knob (Fig.3). 

NOTE: 

Should the gas control knob be left in  the  PILOT 

position and the pilot extinguished,  pilot gas will 

continue  to  flow  from  the  pilot  head.  The  knob 

should  not  be  left  in  the  pilot  position.  For 

extended  OFF  periods  the  knob  should  be 

returned to the OFF position.

MAINTENANCE 

ENSURE THE APPLIANCE IS ELECTRICALLY SAFE AT ALL TIMES 

FRONT CASE REMOVAL 

1. Pull off the control knobs.

2. Unscrew  the  case  retention  ring  from  the

water flow control.

Page2 

3. Pull  the  case  outward  at  the  bottom  to

release the snap catches.

4. Lift the case upwards off the  retention tabs

and remove case.
