Before leaving the site, check the operation of
programmer, control thermostat are working correctly and
are capable of controlling the burner correctly.
Check the operation of both control boxes.
In the event of flame failure the control boxes should cut
off the oil supply by closing the solenoid valves. The reset
buttons will then be illuminated.
WAIT 30 SECONDS BEFORE RE-SETTING THE
CONTROL BOX.
Check that:-
1.
The boiler system is full of water and the valves are
fully open.
2.
The programmer is set to continuous heating and the
heating switch set to heating.
3.
Ensure that the electricity supply is ON, that the pump
is running and the boiler thermostat is ON.
The boiler and pump should run until the system is hot
and an inspection is made for water leaks.
The system should then be turned off and rapidly drained
whilst still hot, with all manual and automatic valves in the
open position. The system should then again be filled and
cleared of all air locks. Whilst re-filling the system it is
essential that a corrosion inhibitor is added to the feed
water.
When all air locks have been removed and the system is
hot the by-pass should be adjusted to ensure a quiet
operation and the radiators balanced.
4.
Allow the pump adjuster to maintain a “flow and return’
differential temperature of 10°C - 14°C.
Checks must be made by the installer to see that the
differential is obtained after the boiler “Flow” temperature
is stabilised.
The system should be balanced by regulating the water
flow rate through individual heat emitters to ensure
satisfactory water temperature at each emitter.
5.
When the water system reaches working temperature,
check that the boiler thermostat operates satisfactorily.
1.
Advise the User of the precautions necessary to
prevent damage to the heating system and to the
building in the event of the heating system being
inoperative during frost conditions.
2.
Advise the User that, for continued efficient and safe
operation of the appliance, it is important that
adequate servicing is carried out at regular 12
monthly intervals.
3.
Hand the Operating instructions to the User and
demonstrate the correct operation of the appliance
and system controls.
4.
Leave the Installation and Servicing instructions with
the User.
