Installation & Servicing

GENERAL

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 registered CORGI 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 imax boiler only.

These kits and the associated options are suitable for both roof
and wall mounting applications.

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, twin pipe 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 twin pipe and 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

and 45

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: 2000. In IE refer to I.S.813:2002.

The flue must be installed in accordance with Building
Regulations and the recommendations of BS. 5440-1:2000 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.

Due to the compact nature of the boiler the heat stored within the
castings at the point of shutdown of the burner must be
dissipated into the water circuit in order to avoid overheating. In
order to allow pump operation after burner shutdown the boiler
control box incorporates a 5 minute pump overrun facility. In
order to make use of this, the pump must be supplied from the
terminals inside the boiler. Note: for pumps requiring greater
than 1.0 amp current, they must be connected via a relay.

GENERAL

HYDRAULIC RESISTANCE W80 / W100

HYDRAULIC RESISTANCE W45 / W60

When sizing pumps, reference should be made to the graphs
below which show the boiler resistance against flow rates, to
achieve the required temperature differential.
Flow rates for common systems using either 11

C or 20

temperature differentials are given in the table below.

imax W45

0.94 l/s

0.53 l/s

imax W60

1.28 l/s

0.69 l/s

imax W80

1.69 l/s

0.94 l/s

imax W100

1.17 l/s

Note.

With the boiler firing at maximum rate, the temperature
differential should not be less than 10

C (14

C for W100).

High flow rates required for lower temperature differentials
could lead to errosion of the heat exchanger water ways.

With the boiler firing at minimum rate, the temperature
differential should not be greater than 35

C. Lower flow rates

generating higher temperature differentials will lead to lock
out of the boiler.

The lower the return temperature to the boiler, the higher the
efficiency.

In installations where all radiators have been provided with
thermostatic radiator valves, it is essential that water circulation
through the boiler is guaranteed. This can be best achieved by
means of a differential pressure valve, which is installed in a
bypass between the flow and return pipes. The bypass should
be fitted at least 6m from the boiler, and should use a minimum
size of 28mm pipe. The bypass should be capable of allowing a
minimum flow rate to achieve a temperature differential of no
greater than 35

C at minimum rate.

WATER TREATMENT

These boilers incorporate an ALUMINIUM heat exchanger.
IMPORTANT. The application of any other treatment to this
product may render the guarantee of Ideal Stelrad Group
INVALID.
Ideal Stelrad Group recommend Water Treatment in
accordance with Guidance Notes on Water Treatment in Central
Heating Systems.

Ideal Stelrad Group recommend the use of Fernox Copal or
MB1 or GE Betz Sentinel X100 inhibitors and associated water
treatment products, which must be used in accordance with the
manufacturers' instructions.

Notes.

1. It is most important that the correct concentration of the water

treatment products is maintained in accordance with the
manufacturers' instructions.

2. If the boiler is installed in an existing system any unsuitable

additives MUST be removed by thorough cleansing.
BS7593:1992 details the steps necessary to clean a
domestic heating system.

3. In hard water areas, treatment to prevent limescale may be

necessary - however the use of artificially softened water is
NOT permitted.

4. Under no circumstances should the boiler be fired before the

system has been thoroughly flushed.

ELECTRICAL SUPPLY

Wiring external to the appliance MUST be in accordance with the
current I.E.E. (BS7671) Wiring Regulations and any local
regulations which apply. For Ireland reference should be made
to the current ETCI rules for electrical installations
The point of connection to the mains should be readily
accessible and adjacent to the boiler.

CONDENSATE DRAIN

A condensate drain is provided on the boiler. This drain must be
connected to a drainage point on site. All pipework and fittings
in the condensate drainage system MUST be made of plastic -
no other materials may be used.
IMPORTANT. Any external runs must be insulated.

valve or restriction. The valve should have the
following features:
a. A non-adjustable preset lift pressure not

exceeding 4 bar (60 lbf/in

b. A manual testing device.

c. Provision for connection of a discharge pipe. The valve

or discharge pipe should be positioned so that the
discharge of water or steam is visible, but will not cause
hazard to user or plant.

3. Pressure Gauge

A pressure gauge covering at least the range 0-4bar must
be fitted to the system. The gauge should be easily seen
from the filling point and should preferably be connected at
the same point as the expansion vessel.

4. Expansion Vessel

Expansion vessels used must comply with BS. 4814.
Connection to the system must not incorporate an isolating

OPEN VENTED SYSTEM REQUIREMENTS

Detail reference should be made to the appropriate
standards listed on page 4.

The information and guidance given below is not intended to
override any requirements of the above publications or the
requirements of the local authority, gas or water undertakings.

The vertical distance between the pump and feed/expansion
cistern MUST comply with the pump manufacturer's minimum
requirements, to avoid cavitation. Should these conditions
not apply either lower the pump position or raise the cistern
above the minimum requirement specified by Ideal Stelrad
Group. The isolation valves should be fitted as close to the
pump as possible.

The boiler is fitted with an automatic air vent, located in the left
top side of the interior. This air vent must never be shut off, as
this could result in dry firing of the boiler and subsequent
damage to the heat exchanger.
