If the appliance fails to ignite after a second sequence switch off the electrical supply to the appliance and 
call the service engineer. 

i.

 

If  gas  failure  occurs  after  successful  ignition  the  appliance  will  attempt  one  re-ignition  before  going  to 
lockout condition. 

j.

 

To shut down the appliance for short periods of time, switch off the electricity supply to the appliance. 

k.

 

To shut down the appliance for longer periods of time, switch of the electricity supply to the appliance and 
turn off the gas supply at the gas isolation valve. 

NOTE:  The  lighting  and  shutdown  instructions  are  also  shown  on  a  permanent  label  attached  adjacent  to  the 
controls for the heater (see section 8.3). 
 

15.0)

 

CLEANING AND ANNUAL MAINTENANCE 

 

This  heater  must  be  cleaned  and  serviced  annually  by  a  qualified  contractor  before  the  start  of  each  heating 
season and at any time excessive accumulation of dust and dirt is observed. Maximum heating efficiency and 
clean combustion will be maintained by keeping the heater clean. 
IMPORTANT: 

a.

 

Do not rest anything, especially ladders, against the appliance. 

b.

 

Gas  and  Electricity  supplies  must  be  isolated  before  commencing  servicing  work  or  replacement  of 
components. 

c.

 

On  completion  of  a  service/fault  finding  task  which  has  required  the  breaking  and  remaking  of  electrical 
corrections, the following checks must be made. 

1.

 

Earth continuity check 

2.

 

Polarity check 

3.

 

Resistance to earth check 

 

d.

 

On completion of service of gas carrying components or replacements the entire gas supply system best be 
checked for leaks. 

e.

 

Commission heater with section 11 and 14. 

The contractor shall check the following during periodic maintenance. 

 

Clearances  to  combustibles:  Check  that  clearances  are  being  maintained.  Make  sure  there  are  no 
flammable objects, liquids or vapors near the heater. See also Section 4.0). 

 

Reflectors:  Reflectors  should  be  kept  clean,  at  a  minimum  blow  off  the  reflectors.  (Dirty  reflectors  will 
reduce heat output).  

 

Heat  exchanger  tubes:  Inspect  the  heat  exchanger  tubes  to  make  sure  they  are  not  cracked,  sagging  or 
showing signs of fatigue.  

 

Combustion air intake: Disconnect combustion air intake from the control box and inspect internally using a 
flashlight  to  make  sure  no  foreign  material  has  collected  in  the  tubes  and  that  there  is  no  obstruction 
around  the  air  intake  openings.  Clean  any  foreign  materials.  Inspect  any  joints  to  make  sure  they  are 
completely sealed. See also Section 13. 

 

Venting  System:  Disconnect  vent  pipe  and  inspect  internally  using  a  flashlight  to  make  sure  no  foreign 
material has collected in the pipes. Check the external vent cap and make sure that there is no obstruction 
around  the  exhaust  openings.  Clean  any  foreign  materials.  Inspect  any  joints  to  make  sure  they  are 
completely sealed. See also Section 13.
