It is also worth noting that the heating system will
usually remain effective for up to half an hour after
boiler shut down. The timer can therefore be switched
off earlier as an economy measure.

FROST PROTECTION

If the boiler and central heating is shut down for many
hours during very cold weather, the water may be in
danger of freezing and, as such, it is advisable to protect
the installation with a frost thermostat.
Where the system is not protected, the boiler should be
left switched on and the room thermostat set to a low
setting e.g. 7° C (45° F) to prevent the building tempera-
ture falling too low.
If the system is shut down for a long period during very
cold weather, it is advisable to completely drain the
system. However, frequent draining should be avoided,
especially in hard water areas, as this could lead scaling
of the boiler waterways.
SHUTTING DOWN FOR THE SUMMER
If the boiler is shut down for the summer months, it is
advisable to have it serviced and thoroughly cleaned as
soon as possible to minimise corrosion of the heating
surfaces.
OIL
The recommended oil for your boiler is 28 sec.Kerosene
(BS 2869:1983 Class C2).
OIL TANK
Always ensure the tank is topped up at regular intervals,
do not wait until the tank is nearly empty before refilling,
otherwise sludge and water could be sucked into the oil
pipe to affect the burner's operation and reduce pump
life.
After a delivery of oil, it is recommended that the oil is
allowed to settle in the tank for about half an hour before
restarting the burner.

Sludge and water caused by condensation should be
drawn off at the tank drain-cock annually.

SIMPLE FAULT FINDING

If the burner fails to start for no apparent reason, make
the following checks before calling your Service
Engineer.
1. Check for failure in the electrical supply e.g. a power
cut
2. Check for a blown fuse. If the fuse has blown and on
replacement blows again, switch off the mains
electrical supply to the boiler and call your Service
Engineer.
3. Check that there is adequate oil in the tank and the
shut-off valves are open.
4. Check for burner lock-out. Press the reset button
and burner should fire. DO NOT PRESS MORE
THAN TWICE. Refer to 'Burner lock-out' for further
advice.
Note: If the boiler has been off as a result of a power
failure, it will be necessary to reset the Time
Switch/Programmer to the correct time unless it
has a built-in power reserve.
SERVICING
To ensure efficient and reliable operation of the boiler, it
is essential that the oil burner is initially commissioned by
an OFTEC trained and registered engineer and an annual
service is given thereafter.
Notes:
ELECTRICAL SAFETY CHECKS SHOULD BE CARRIED
OUT BY A QUALIFIED ELECTRICAL ENGINEER
a It is the responsibility of the installer to ensure proper
commissioning is carried out.
b It is a requirement of the boiler's guarantee and any
extended warranty that an annual service is carried
out by a qualified engineer.
