Section 7.
Servicing Instructions
WARNING
Only Competent and Qualified Engineering Staff should carry out
SERVICING AND FAULT FINDING ON THIS EQUIPMENT.
Before any maintenance is carried out, ensure that both fuel and electrical supplies are turned off as the main fan(s)
can start, at any time whilst the electricity is turned on, under the control of the combination fan/limit thermostat.
NOTE 1
:
After any maintenance work always test fire the heater in the prescribe manner to make
sure all safety systems are in working order before leaving the heater to run normally.
NOTE 2
:
Check all pipe joints with the burner running. Any leaks must be repaired before leaving
the heater to fire normally.
NOTE 3
:
After routine maintenance, the commissioning procedure, Section 5 must be carried out
to ensure that peak efficiency and safety is maintained.
After commissioning the heater will require very little maintenance.
It is recommended one service a year is carried out to the procedures detailed below, except in dirty or dusty environments
where servicing may be required more frequently.
Minor faults may be traced by use of the Fault Finding charts in Section 9.
A list of parts that may be needed during maintenance is given in Section 11.
7.1
Burner Maintenance
See the Manufacturers Information for specific instructions.
The maintenance of the burner should include cleaning of the fan (and fuel filters when fitted), inspection of all components
including the flame monitoring and ignition system and correct operation of fuel control valves.
For oil fired burners it is recommended that the atomising oil nozzle is replaced during the annual service with one of
the correct make, size and type.
7.2
Main Fan
The main fan requires very little maintenance as the bearings are sealed for life and need no lubrication. If fan blades
need cleaning remove the heater side panels and use a small brush or duster to clean the blades from each side of the
fan(s).
On belt drive fans, check belt condition. This is best carried out with belts removed, and examine for lateral cracks or
chaffing, replace if necessary. Double belts should be replaced together as a pair.
Check belt tension see Fig. 7.1. Do not over-tighten belts as this may cause bearing damage.
