SYSTEM CONTROLS
Room thermostat
To prevent the boiler switching off before the
room has reached the required temperature, the
room thermostat should not be positioned near a
heat source, such as a radiator, or be exposed to
direct
sunlight. Follow the manufacturer's
guidance for optimum siting positions.
Programmer
When choosing the operating times for the boiler,
remember that the central heating system may
take up to one hour before becoming effective,
and will usually remain warm for up to half an
hour after the boiler has switched off. As such, it
may be possible to switch the programmer off
early as an economy measure.
Frost protection
If the boiler is to be switched off during very cold
weather, or is located in a boiler room external to
the property that is being heated, the water may
be in danger of freezing. This can be prevented
by fitting the boiler with a frost thermostat that will
cause the boiler to light if the temperature nearby
drops too low.
Where the system is not protected, the boiler can
be left on and the room thermostat set to a low
position (e.g. 5°C).
System shut-down
If the system is off for long periods during very
cold weather, it may be advisable to completely
drain the system. Be aware that too-frequent
draining should be avoided
—especially in hard
water areas
—as this could lead to scale build-up
in the boiler waterways.
If the boiler is to be shut down for the summer
months, it is advisable to have it serviced as soon
as possible, to minimise the risk of corrosion to
the heating surfaces.
OIL
The only heating oil suitable for use on this boiler
is kerosene class C2.
DO NOT use any other
heating oil. Failure to use the correct oil will
invalidate the warranty.
Ensure the oil storage tank is topped up regularly;
do not wait until the tank is empty, as sludge and
water could be drawn into the supply pipe,
adversely affecting the operation of the burner
and potentially reducing the life expectancy of the
oil pump.
After an oil delivery, allow half an hour for the oil
to settle in the tank before using the boiler. Sludge
and water caused by the build-up of condensation
should be drawn off at the drain cock on the tank
once per year.
FAULT-FINDING
If the boiler fails to start, carry out the following
checks before contacting your service engineer:

Check for failure in the electrical supply

Check for a blown fuse. If the fuse has blown
and the replacement also blows, switch off the
mains electrical supply to the boiler and
contact your service engineer.

Check that there is oil in the tank and that all
isolation valves are fully open.

Check for burner lockout ( page 4 ).

Check that the boiler thermostat is switched
on and that the programmer and room
thermostat are calling for heat.

Check that the high-limit thermostat has not
operated (
page 4 ).
Note: if the boiler has been shut down due to a
failure of the electrical supply, it may be
necessary to reset the programmer to the
correct time, unless the device has an in-
built power reserve.

guidance for engineers.
COMMISSIONING & SERVICING
To ensure the continued efficient and reliable
operation of the boiler, it is essential that the
burner be commissioned immediately after
installation and prior to first use. The boiler
requires an annual service thereafter.
Important notes
It is a requirement of the guarantee and any
extended warranty that the boiler is commissioned
and receives an annual service. It is the
responsibility of the installation engineer to ensure
commissioning is carried out.
Commissioning and servicing must be performed
by a qualified engineer, preferably OFTEC trained
and registered. Electrical safety checks should be
carried out by a qualified electrical engineer.
It is a requirement of the guarantee and any
extended warranty that the system is flushed out
and protected with an appropriate corrosion
inhibitor, e.g. Fernox.
