Where using heavy oil do not switch off fuel heaters
and tracers. Switch off electrical supply to gas boos-
ter.
6.4.2 Summer
Shut
Down
If the boiler is to be out of operation for a long period,
e.g. during the Summer, the boiler interior should be
thoroughly cleaned.
Atmospheric condensation, activating acidic deposits in
the boiler, is responsible for considerable corrosion and
metal wastage. Every effort should be made to reduce
this by the most thorough cleaning and by keeping the
boiler dry.
A tray of absorbing material placed in the combustion
chamber is helpful in this respect. Close the boiler door.
6.4.3 Burner
Maintenance
Before carrying out any work on the burner ensure
that the main electrical isolating switch is locked in
the OFF position and the fuel isolating valve closed.
operator and are intended to be of assistance in making
maintenance, cleaning and lubrication. Additional infor-
mation can be obtained through your installer or from the
manufacturer.
• Fuel
The unit is designed to burn the fuel stated on the bur-
ner nameplate. Under no circumstances must any
other type of oil or gas be used.
In the case of burner fuel conversion, check to see that
the fuel used corresponds with that marked on the new
burner nameplate.
• Starting and Stopping
• Emergency Stop
The burner can be stopped in an emergency by
switching off the mains isolating switch provided on the
line between the burner and the electric supply. The in-
staller must identify the switch. Check position of this
switch or any ‘panic button’ available.
• Check the Burner Operation
-
call the service engineer.
When cleaning the room housing the heater unit, al-
ways switch off the burner to reduce the amount of dust
and lint drawn in through the air inlet.
• Preventive Maintenance
Consult your heating engineer for advice on regular
prevetive maintenance intervals.
16. Gas Supply
Should the gas supply be interrupted, the system may
require venting of air that may have accumulated,
before the burner is restarted. This is achieved by un-
screwing the pressure test point situated down-stream
of the main govenor or combination valve and venting
the air to atmosphere until gas has reached the test
point.
WARNING:
No smoking or naked lights to be allowed
as a gas/air mixture is dangerous.
Periodical examination of all pipework should be carri-
ed out. The recommended method is to brush a soap
solution around all the jointed areas. A leak in the sys-
tem would have the effect of forming bubbles.
CAUTION:
Do not place any items in the boiler com-
bustion chamber as it is not suitable for
burning waste.
• Oil pump
See burner manufacturers manual.
• Gas train items and gas leak detectors
For maintenance of these units refer to the manufac-
turers manual.
