Installation & Servicing
GEnERAL
During all manoeuvres and handling actions, every attempt should
be made to ensure the following unless unavoidable and/or the
weight is light.
• Keep back straight.
• Avoid twisting at the waist.
• Avoid upper body/top heavy bending.
• Always grip with the palm of the hand.
• Use designated hand holds.
• Keep load as close to the body as possible.
• Always use assistance if required.
SAfE HAnDLInG of SubStAnCES
No asbestos, mercury or CFCs are included in any part of the
boiler or its manufacture.
LoCAtIon of boILER
The boiler must be installed on a flat and vertical wall, capable of
adequately supporting the weight of the boiler and any ancillary
equipment or on a boiler frame supplied in kit form by
Ideal
Stelrad Group
.
The boiler must not be fitted outside.
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 or in IE by a competent person.
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 boiler inlet gas
connection.
The complete installation MUST be tested for gas soundness and
purged in accordance with the appropriate standards listed on
page 4.
fLuE InStALLAtIon
The flue kits are suitable for use with the EVOMAX boiler only.
These kits and the associated options are suitable for both roof
and wall mounting applications. The Horizontal Wall Flue Kit
is not for use with Evomax 150 boilers in compliance with the
requirements of the Clean Air Act Memorandom.
The roof flue kits are suitable for both flat and pitched roof
termination, using either concentric or flue only terminals.
Connection to the top of the boiler is made using a separately
supplied vertical connector in concentric and open flue
configurations (supplied in our optional extra kits).
Additional information covering the selection and installation can
be found with this booklet.
Weather Proofing
Where the flue passes through the roof line an adequate seal
must be made. This can be achieved by using either:
•
Flat weather collar
•
Pitched weather collar
Flue duct extension kits are available for concentric flue
configuration. These packs contain additional 1 metre ducts and
may be cut to the desired length.
Flue duct extension kits are available for open flue configurations.
These packs contain 2 x 1 metre ducts and may be cut to the
desired length.
If obstructions prevent direct flue routing then both 90
o
and 45
o
elbows can be provided to offset the flue system.
terminal Position
Due to the high efficiency of the boilers pluming will occur. For
this reason, vertical termination is recommended, and in any
case, terminal positions which could cause problems should
where possible be avoided. Particular care should be taken in the
case of large multiple boiler installations, and complying with the
requirements of the Clean Air Act.
ImPoRtAnt
It is the responsibility of the installer to ensure, in practice, that
products of combustion discharging from the terminal cannot
re-enter the building or any other adjacent building through
ventilators, windows, doors, other sources of natural air infiltration,
or forced ventilation / air conditioning.
If this should occur the appliance MUST be turned OFF, labelled
as ‘unsafe’ and corrective action taken.
Where the lowest part of the terminal is fitted less than 2m (80”)
above a balcony, above ground or above a flat roof to which
people have access then the terminal MUST be protected by a
purpose designed guard. The minimum spacing between the
balcony and the terminal should be 75mm, in order to allow a
terminal guard to be fitted.
Terminal guards are available from boiler suppliers - for all
requirements contact:
Grasslin (UK) Ltd., Tower House, Vale Rise,
Tonbridge, Kent TN9 1TB.
Tel: +44 (0) 1732 359 888. Fax: +44 (0) 1732 354 445
www.tfc-group.co.uk
Ensure that the guard is fitted centrally.
The air inlet/products outlet duct and the terminal of the
boiler MUST NOT be closer than 25mm (1”) to combustible
material. Detailed recommendations on the protection of
combustible material are given in BS. 5440-1: 2008. In IE refer to
I.S.813:2002.
The flue must be installed in accordance with Building
Regulations and the recommendations of BS. 5440-1:2008 for
inputs up to 70kW nett. For larger installation BS. 6644 should be
complied with. In IE refer to I.S.820:2000.
WAtER CIRCuLAtIon SyStEm
The system pump MUST be connected to the boiler, see below.
The boiler must NOT be used for direct hot water supply. The hot
water storage cylinder MUST be of the indirect type.
Single feed, indirect cylinders are not recommended and MUST
NOT be used on sealed systems.
The appliances are NOT suitable for gravity central heating nor
are they suitable for the provision of gravity domestic hot water.
The hot water cylinder and ancillary pipework, not forming part of
the useful heating surface, should be lagged to prevent heat loss
and any possible freezing - particularly where pipes run through
roof spaces and ventilated underfloor spaces.
The boiler must be vented.
Draining taps MUST be located in accessible positions, which
permit the draining of the whole system - including the boiler
and hot water storage vessel. They should be at least 1/2” BSP
nominal size and be in accordance with BS. 2879.
The central heating system should be in accordance with the
relevant standards listed on page 4.
