compressors on industrial and commercial
premises.

IGE/UP/10

Installation of gas appliances in industrial and
commercial premises.

SAFE HANDLING OF SUBSTANCES

No asbestos, mercury or CFCs are included in any part of the
boiler or its manufacture.

FOUNDATION / LOCATION OF BOILER

The boiler must stand on a floor which must be flat, level and of a
suitable load bearing capacity to support the weight of the boiler
(when filled with water) and any ancillary equipment.
Ideally the boiler should be placed on a plinth exceeding the plan
area of the boiler by 75mm on each side and at least 100mm high.
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
15mbar MUST be available at the boiler inlet for Natural gas.
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.
Gas Boosters
A gas booster is required if the gas pressure available at the boiler
is lower than that required by the boiler 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
temperature do not exceed designed recommendations. Further
guidance is provided in IGE/UP/2.

Installation & Servicing

GENERAL

FLUE INSTALLATION

The appropriate Ideal Flue Header Kit (veritcal or horizontal)
must be fitted to these boilers.
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 isolated from the
gas supply and labelled as 'unsafe' until corrective action can be
taken.
Terminal Position
Due to the high efficiency of the boilers pluming will occur.
Particular care should be taken in the case of large output boiler
installations, and complying with the requirements of the Clean
Air Act.
The flue must be installed in accordance with the appropriate
Building Regulations and standards listed on page 4 and in
compliance with BS6644. In IE refer to I.S.820:2000.

FLUE SYSTEM DESIGN

Due to the high efficiency of these boilers, the flue gas
temperatures are low and the buoyancy in the stack will be
relatively small. The boiler is supplied with an integral fan which
is fully matched to the boiler in each case to provide correct
combustion air flow and overcome the flue resistance.
The power of this fan is such that there is a large reserve of
pressure available to overcome a significant length of flue
without affecting the combustion performance of the boiler. The
maximum pressure available at the base of the flue to overcome
flue resistance is 145Pa (0.58" w.g.) for F320, F400, F480 and
F560. This includes the resistance of any air ducts used to
connect the air inlet direct to outside air. Care should be taken
with tall flue systems to ensure excess buoyancy is not created.
A negative pressure must not be created at the boiler flue outlet.
See table below for approximate maximum straight flue lengths.
The addition of elbows and their positions in the flue will have a
significant effect on the maximum allowable flue and air duct
lengths. Consult with your flue supplier for detailed design
work.

IMPORTANT NOTE.
If combustion air is drawn from within the boiler room, ensure

no dust or airborne debris can be ingested into the appliance.

Dusty concrete flooring should be sealed to reduce the

presence of dust. Ideally where possible duct the air supply

into the boiler room from a clean source outside the boiler

room / building.

Material
With no requirement for buoyancy to discharge flue products and
with low flue gas temperatures, single wall flues are suitable for
most installations. Care should still be taken to maintain
compliance with building regulations and relevant standards.
The flue used should be a suitably approved flue for use on a
pressurised condensing flue system. Materials choice includes
plastic, aluminium and 316 grade stainless steel. Unless the
flue is manufactured from aluminium, the condensate from
the flue must be collected and drained before entering the
sump of the boiler (when employing the vertical combined flue
outlet header, a flue condensate drain is provided for this
purpose). Advice regarding the availability of proprietary types of
flue system can be obtained by contacting Ideal Stelrad Group.
All joints or connections in the flue system must be impervious
to condensate leakage. Low points in the flue system should be
drained using pipe of material resistant to condensate
corrosion. All drains in the flue should incorporate a water trap.
Care should also be taken in the selection of flue terminals as
these tend to accentuate the formation of a plume and could
freeze in cold weather conditions.
Care should be taken to ensure the specification of the chimney
is suitable for the application by reference to the manufacturers
literature.

GENERAL

WATER CIRCULATION SYSTEM

A circulation 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. There must be no low points
between the boiler flow connection and a system vent point,
which should be positioned as close as practically possible to
the boiler flow connection.
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. Do not use
the boiler drain tap to drain the system as this can induce
sludge into the heat exchanger.
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, a 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.
When sizing pumps, reference should be made to the Hydraulic
Resistance Table on page 6 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.

Note.
·

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

C. Higher flow rates

required for lower temperature differentials could lead to
erosion 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. At return temperatures of 55

C and below, the

difference becomes marked because the water in the flue
gases starts to condense, releasing its latent heat.

In installations where all radiators have been provided with
thermostatic radiator valves, it is essential that water circulation
through the boiler is guaranteed. A mixing header will perform
this task. Alternatively 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 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.

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.

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

WARNING. This appliance must be earthed.
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

Condensate drains are provided on the boiler. These drains
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 to avoid
freezing in cold weather causing blocking.

VENTILATION

The ventilation requirements of these boilers are dependant
on the type of flue system used, and their heat input. All vents
must be permanent with no means of closing, and positioned
to avoid accidental obstructions by blocking or flooding.
Detail reference should be made to BS. 6644 for inputs
between 70kW and 1.8MW (net). In IE refer to the current
edition of I.S.820. The following notes are for general
guidance only:
Dust contamination in the combustion air may cause blockage
of the burner slots. Unless the boiler room provides a dust
free environment then direct connection of the air intake via
ducting to clean outside air should be used.
IMPORTANT NOTE.
If combustion air is drawn from within the boiler room,

ensure no dust or airborne debris can be ingested into the

appliance. Dusty concrete flooring should be sealed to
reduce the presence of dust.
The temperature within a boiler room shall not exceed 25

within 100 mm of the floor, 32

C at mid height and 40

C within

100 mm of the ceiling.

Open Flued Installations
If ventilation is to be provided by means of permanent high and

Particular reference should be made to BS. 6644 and
Guidance note PM5 "Automatically controlled steam and hot

The information and guidance given below is not intended to
override any requirements of either of the above publications or
the requirements of the local authority, gas or water
undertakings.
In general commercial closed pressurised systems are
provided with either manual or automatic water make up.
In both instances it will be necessary to fit automatic controls
intended to protect the boiler, circulating system and ancillary
equipment by shutting down the boiler plant if a potentially
hazardous situation should arise.
Examples of such situations are low water level and operating
pressure or excessive pressure within the system. Depending
on circumstances, controls will need to be either manual or
automatic reset. In the event of a shutdown both visual and
audible alarms may be necessary.

Expansion vessels used must comply with BS. 4814 and must
be sized on the basis of the total system volume and initial
charge pressure.
Initial minimum charge pressure should not be less than 0.5
bar (7.2psi) and must take account of the static head and
specification of the pressurising equipment. The maximum
water temperatures permissible at the point of minimum
pressure in the system are specified in Guidance Note PM5.
When make up water is not provided automatically it will be
necessary to fit controls which shut down the plant in the event
of the maximum system pressure approaching to within
0.35bar (5psi) of the safety valve setting.
