SERVICING THE BURNER
WARNING
Any change to this heater or its controls can be
dangerous.
First, remove the front section of the frame (see Fitting The Glass Facia
section), the glass panel . Detach the burner front cover plate by removal
of the four retaining screws . Disconnect the gas connection inside appli-
ance . The gas connections to the gas valve can now be released . Undo
the four screws retaining the burner brackets to the base and rear of the
firebox . The burner may now be removed .
Remove the pilot and main burner pipes and blow through to dislodge
any debris . Now remove the in-line restrictor and blow through to make
sure it is entirely clear .
Unclip the pilot lint gauze and clean with a soft brush . Clean the exterior of
the pilot assembly with a soft brush and blow through the flame ports on
the pilot head . Check the aeration holes are free from lint or dirt . The pilot
assembly can be removed if required by disconnecting the electrode HT
lead, gas pipe, thermocouple lead and unscrewing the mounting screws
and lifting away . The pilot assembly is a non-serviceable item and should
not be taken apart . Aeration holes must be clear internally for proper
operation .
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE
THE PILOT STAY LIT.
Modifications are dangerous and can have serious
unseen effects on safety . If the pilot will not stay lit there is a problem
with dirt, the gas supply to it, or the thermocouple needs replacement .
The gas valve is a non-serviceable item. If it needs replacement,
replace the burner assembly. Replacement must be original manu-
facturers parts.
Re-assemble in the reverse of removal . Ensure setting pressures are as
stated in Table 1 on Page 7 .
PILOT ASSEMBLY
WARNING
No adjustments are to be made to the ODS pilot
system. Tampering with this system can be extremely
hazardous.
Remove the casing, glass panel and burner unit (as per servicing sec-
tion), lint arrestor and pilot assembly by using a screwdriver to remove
the retaining screws .
Clean the pilot assembly with a soft brush and blow through . Check the
aeration holes are free of any dirt or lint . Clean thoroughly internally,
the connection can be removed from the base of the pilot assembly
using two wrenches to make cleaning easier . Do not damage or try to
dismantle the pilot injector .
The unit is factory set and the only check necessary is to ensure the
spark gap is correct . See specifications for gas setting .
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT
STAY LIT.
If the pilot will not stay lit there is a problem with dirt, the
gas supply, or the thermocouple needs replacement . Modifications are
dangerous and can have a serious unseen effect on safety and therefore
MUST not be done . Replacements must be origi nal manufacturers parts .
Re-assemble in the reverse of removal . Ensure setting pressures are as
stated in Table 1 on Page 7 .
