SYSTEM CONTROLS
ROOM THERMOSTAT
The room thermostat should not be positioned near a
source of heat such as a radiator or exposed to the sun as
this will cause the central heating to switch off before the
room is up to temperature. Follow the manufacturer’s
instructions for best siting position for the thermostat.
FROST PROTECTION
If the boiler and central heating is shut down for many
hours during very cold weather, the water may be in dan-
ger 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 temperature 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 to scaling
of the boiler waterways.
OIL
The recommended oil for your boiler is 28 sec. Kerosene
(BS 2869: 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 drain-cock annually.
SIMPLE FAULT FINDING
NOTE:
Before removing any components or insulation
please read the advice on Health and Safety in the
Insulation & Servicing Instructions.
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 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.
5. Check for excess water temperature (Refer to ‘High
Limit Thermostat’ for advice).
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 CAR-
RIED 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.

HARD WATER AREAS
If you live in a hard water area, and you have a salt based
water softener fitted, please ensure that the recommended
salt levels are maintained. This is to prevent scale forming
on your plate heat exchanger and ultimately the loss of hot
water performance.
