BURNER WILL NOT LIGHT 

 

Is there gas to the water heater? 

Check the gas isolation valve on the gas supply line is open. 

 

Is there a normal gas supply to the rest of the premises? 

Try lighting another gas appliance. If there is no gas call your gas provider. 

 

Is the 

ignition system ‘locked out’? 

Try resetting the water heater. Refer to 

“Water Heater Not Operating” on page 9. 

 

Is the High Limit tripped: 

The  manual  reset  over  temperature  switch  will  shut  down  the  water  heater  in  the  event  of  a  fault  with  the 
temperature control or water flow. When the system water temperature has cooled sufficiently, the red button 
can  be  pressed,  this  will  restart  the  water  heater.  Should  frequent  resetting  be  necessary,  call  your  nearest 
Rheem Service Department or Accredited Service Agent. 

PRESSURE RELIEF VALVE RUNNING 

 

Normal Operation 

It  is  normal  and  desirable  that  this  valve  allows  a  small  quantity  of  water  to escape  during  the  heating  cycle. 
However,  if  the  discharge  is  deemed  excessive  (more  than  2%  of  hot  water  used),  there  may  be  another 
problem. 

 

Continuous dribble 

Try  gently  raising  the  easing  lever  on  the  relief  valve  for  a  few  seconds  (refer 

to  “Pressure  Relief  Valve”  on 

page 19). This may dislodge a small particle of foreign matter and clear the fault. Release the lever gently. 

 

Steady flows for long period (often at night) 

This may indicate the mains water pressure sometimes rises above the designed pressure of the water heater. 
Ask your installing plumber to fit a pressure limiting valve. 

 WARNING:

 Never replace the relief valve with one of a pressure rating greater than 850 kPa. 

EXPANSION CONTROL VALVE RUNNING 

If an expansion control valve is fitted in the cold water line to the water heater (refer to page 18) it may discharge a 
small  quantity  of  water  instead  of  the  pressure  relief  valve  on  the  water  heater.  The  benefit  is  that  energy  is 
conserved as the discharged water is cooler. 

HIGH GAS BILLS 

Should you at any time feel your gas account is too high, we suggest you check the following points: 

Is  the  relief  valve  running  excessively?  (Refer  to 

“Pressure Relief Valve Running” 

on page 10). 

Are outlets (especially the showers) using more hot water than you think? (Refer to 
“Not Enough Hot Water” on page 9). 

Is there a leaking hot water pipe, dripping hot water tap, etc? Even a small leak will 
waste a surprising quantity of hot water and gas. Replace faulty tap washers, and 
have your plumber rectify any leaking pipe work. 

Consider  recent  changes  to  your  hot  water  usage  pattern  and  check  if  there  has 
been any increase in tariffs since your previous account. 

Is  there  excessive  heat  loss  from  the  building?  Check  that  there  are  no  large 
uncovered  windows,  ceiling  insulation  is  installed  and  there  are  no  excessive 
draughts.  

 

IF  YOU  HAVE  CHECKED  ALL  THE  FOREGOING  AND  STILL  BELIEVE  YOU  NEED  ASSISTANCE,  PHONE 
YOUR NEAREST RHEEM SERVICE DEPARTMENT OR ACCREDITED SERVICE AGENT
