HEALTH AND SAFETY PRECAUTIONS
STANDARDS & REGULATIONS
PERFORMANCE
AIR SUPPLY
Please take care when installing the appliance that the
requirements of the Health and Safety at Work Act
1974 are met.
Some types of fire cement are caustic and should not
be allowed to come into contact with the skin. In case
of contact wash with plenty of water.
No asbestos is used in the appliance but if there is a
possibility of disturbing any asbestos in the course of
installation then appropriate protective equipment must
be used.
When handling insulating materials a suitable face mask
and protective gloves should be worn.
Take care when handling fuel oil which can cause skin
irritation, avoid contact with the skin or clothing, take
care to wash hands well after contact with fuel oil and
before eating. Fuel oil must never be taken internally.
In addition to these instructions the requirements of the
following standards must be fulfilled:
BS 5410 Pt 1 Oil Installations Under 45 kW
BS 5449 Forced Circulation hot water central
heatingsystems for domestic premises
BS 7671 Electrical Wiring Regulations
Local Authority Bylaws and Building Regulations
regarding the installation of Oil Burning Appliances,
flues and chimneys and The Control of Pollution (Oil)
Regulations must also be observed.
Oil boilers should be installed in accordance with good
practice as recommended by OFTEC (The Oil Firing
Technical Association for the Petroleum Industry,
Banstead, Surrey. Tel: 01737 373311.)
The output of the boiler is adjustable between 11-13
kW(38-44,000 Btu/h), a small amount of heat will be
given out to the room but for purposes of sizing the
system this should be ignored. The optional Fan Heater
provides up to 2KW of heat to the room.
boiler and a ducted air supply must be provided to the
right hand side of the boiler at this point. A two metre
length of flexible ducting and fixing clips are supplied
with the appliance to connect the air input from the
appliance silencer to the rigid plastic ducting. The air
pipe should be sealed into the appliance using a silicone
sealant. The ducting should be run in 50 mm dia. (2")
plastic pipe and must terminate in free air - preferably
either outside or in a ventilated loft space. The end of
the ducting must be fitted with a suitable cage to
prevent entry by birds or small mammals. The ducting
should be boxed in where it passes through living areas.
The length of ducting should be kept to a minimum,
and the maximum recommended length is 10 metres
incorporating up to 4 bends. (One bend is approx.
equivalent to 1 metre of straight pipe).
Provided that the ducting terminates as described
above there is no requirement for a separate
combustion air supply in the room in which the
appliance is installed. However, if the ducting
terminates within a living space then there must be an
adequate air supply into that room totalling at least 55
sq. cm. (8.5 sq. inches) to provide combustion air.
The chimney should comply with BS5410: Part 1 and
must meet Building Regulations.
The diameter of the chimney must not be less than 100
mm (4”) internal diameter.
As the boiler operates at high efficiency, it is important
that the chimney is well insulated in order to prevent
condensation forming.
Brick or stone chimneys should be lined with a suitable
liner. If a stainless steel liner is used in a brick or stone
chimney then it must be insulated between the liner and
the brickwork in order to prevent condensation that
can reduce the life of both the liner and the boiler.
Pumice liners will give the required level of insulation.
As the flue outlet temperature is below 250°C stainless
steel flexible flue liners suitable for oil may be fitted
directly onto the appliance, although in the interests of
reducing flue noise it is preferable to use a 600 mm
length of rigid flue pipe from the appliance to the liner.
