Installation & Servicing
GENERAL
SAFETY
Current Gas Safety (Installation and Use) Regulations or
rules in force.
It is law that all gas appliances are installed and serviced
by a Gas Safe Registered Engineer in accordance with the
regulations below. Failure to install appliances correctly could
lead to prosecution. It is in your own interest, and that of safety,
to ensure the law is complied with.
The following must be conformed with:
Current Building Regulations and Clean Air Act
Water Authority Regulations
Local Authority Regulations and Regional Bylaws
Gas Safety Regulations
Any special regional requirements of local Electricity and Gas
undertaking.
Fire Service and Insurance Company requirements.
In the interests of safety, a competent installer should
be employed to effect the installation of the appliance.
Manufacturer's notes must NOT, in any way, be taken as over
riding statutory obligations.
The installation of the boiler MUST also be in accordance with
the latest I.E.E. (BS7671) Wiring Regulations, local buildings
regulations, bye-laws of the local water authority, the building
regulations and the Building Standards (Scotland) and any
relevant requirements of the local authority.

SAFE HANDLING OF SUBSTANCES
Care should be taken when handling the boiler insulation panels,
which can cause irritation to the skin. No asbestos, mercury or
CFCs are included in any part of the boiler or its manufacture.
GAS SUPPLY
The local gas supplier should be consulted, at the installation
planning stage, in order to establish the availability of an adequate
supply of gas. An existing service pipe must NOT be used without
prior consultation with the local gas supplier.
A gas meter can only be connected by the local gas supplier or by
a Gas Safe Registered Engineer.
An existing meter should be checked, preferably by the gas
supplier, to ensure that the meter is adequate to deal with the
rate of gas supply required. A minimum working gas pressure of
17.5mbar MUST be available at the boiler inlet for Natural gas
and 37mbar for Propane.
Do not use pipes of smaller size than the burner inlet gas
connection.
The complete installation MUST be tested for gas soundness and
purged in accordance with the appropriate standards listed above.
Gas Boosters
A gas booster is required if the gas pressure available at the
burner is lower than that required by the burner manufacturer to
attain the flow rate for maximum burner input rating.
Location of the booster requires careful consideration but
should preferably be closer to the burner rather than the gas
meter. Ventilation should also be considered to ensure ambient
temperatures do not exceed designed recommendations. Further
guidance is provided in IGE/UP/2 as listed above.
FLUE INSTALLATION
IMPORTANT
It is the responsibility of the installer to ensure that products of
combustion discharging from the terminal cannot re-enter the
building or any other adjacent building.
Fan dilution systems may be incorporated into the flue system.
However, ventilation must take into account the additional air
requirement of the boiler house and interlocking must be provided
to ensure adequate air flow is attained before burner operation
proceeds.
The flue must be installed in accordance with the appropriate
standards listed on page 6.
