BENSON AH150 - Servicing - Recommissioning

Note
It is most important that a build up of deposits is not allowed to occur as this can have an
adverse effect upon the efficiency of the heater and reduce the life of the heat exchanger.
(f) The heat exchanger and combustion chamber should be visually inspected for signs of splits,
cracks,
and distortion.
If the condition of the heat exchanger gives cause for concern the Service Department at
Benson Environmental Ltd should be advised pending a more detailed examination.
(g) All gaskets should be checked to ensure that they continue to provide a gas tight seal, if there
is an element of doubt then they should be replaced.
Electrical Supply
All connections must be checked to ensure that they are secure, and free from corrosion.
Terminals and connections should also be checked to ensure that no stray strands are bridging
terminals. Electrical continuity should also be checked.
Oil Supply
The oil supply pipework, tank, and fittings should all be inspected to ensure that they are free
from corrosion, and to ensure that where brackets have been fitted these remain secure and offer
adequate support. The oil filter should be replaced with a new one, and the system should be
checked for leaks. If the oil level is such as to allow removal of any sludge or other contaminants
from the tank this too should be undertaken, particularly if there have been prob l ems of poor
firing associated with contaminants reaching the burner.
Note
Any waste oil or sludge must be disposed of correctly. Never dispose of it by dumping or
tipping it down drains or into water courses where ground water can become polluted and
environmental damage caused.
Burner
Service requirements for the burner fitted to the cabinet heater are covered in the separate
manual prepared by the burner manufacturer.
Note
It is most important that the burner is serviced regularly and in accordance with the
manufacturers instructions.
Air Delivery System
A visual inspection should be undertaken to ensure that the air delivery system is in good
order, that it remains adequately supported and that the various joints are effectively sealed.
Report
A full and detailed service report should be prepared, it is advised that the report is not
completed until the heater has been re-commissioned, where upon the completed report can then
be run through with the user.
5.3 Service Re-commissioning
The heater must be re-commissioned as follows; as per section 4.1 through to section 4.4
inclusive. This must be regarded as a necessary part of the heater service by the servicing engineer.
