GENERAL
Note.
Natural gas consumption is calculated using a caloric value of
37.8MJ/m3 (1038Btu/ft3) gross or 34 MJ/m3 (910 Btu/ft3) nett at
15oC and 1013.25 mbar.
a. For l/s divide the gross heat input (kW) by the gross C.V. of the
gas (MJ/m3)
b. For ft/h3 divide the gross heat input (Btu/h) by the gross C.V. of
the gas (Btu/ft3).
c. For m3/h multiply l/s by 3.6.
d. 1kW = 3412 BTU/hr.
e. 1m3 = 35.3ft3
f. 1mg/kWh (NOx) = 0.568 ppm DAF (natural gas).
Propane gas consumption is calculated using a caloric value of
95.7 MJ/m3 (2500 Btu/ft.3) gross or 88.0 MJ/m3 (2300 Btu/ft.3) net
at 15oC and 1013.25 mbar.
To obtain the fuel consumption in liquid form divide the above
gures by 270.
* The value is used in the UK Government’s Standard Assessment
Procedure (SAP) for energy ratings of dwellings. The test data from which
it has been calculated have been certied by a notied body.

SAFE HANDLING
This boiler may require 2 or more operatives to move it to its installation
site, remove it from its packaging base and during movement into its
installation location. Manoeuvring the boiler may include the use of a
sack truck and involve lifting, pushing and pulling.
Caution should be exercised during these operations.
Operatives should be knowledgeable in handling techniques when
performing these tasks and the following precautions should be
considered:

9
EVOMAX - Installation & Servicing
GENERAL
• Grip the boiler at the base.
• Be physically capable.
• Use personal protective equipment as appropriate, e.g.
gloves, safety footwear.
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 at 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
Boilers.
The boiler must not be tted 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 an RGI 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 boiler inlet gas
connection.
The complete installation MUST be tested for gas soundness and
purged in accordance with the appropriate standards listed on
page 8.
FLUE INSTALLATION
DANGER; ONLY USE IDEAL ROOM SEALED FLUE
GAS SYSTEMS. THE BOILER CE MARK IS VALID
ONLY IF THE APPLIANCE IS OPERATED WITH IDEAL
ROOM SEALED FLUE KITS. OTHER FLUE SYSTEMS
ARE NOT TESTED WITH THIS APPLIANCE.
The ue 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 ue kits are suitable for both at and pitched roof
termination, using either concentric or ue only terminals.
Connection to the top of the boiler is made using a separately
supplied vertical connector in concentric and open ue
congurations (supplied in our optional extra kits).
Additional information covering the selection and installation can
be found with this booklet.
Weather Proong
Where the ue 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 ue
conguration. These packs contain additional 1 metre ducts and
may be cut to the desired length.
Flue duct extension kits are available for open ue congurations.
These packs contain 2 x 1 metre ducts and may be cut to the
desired length.
If obstructions prevent direct ue routing then both 90oand 45o
elbows can be provided to offset the ue system.
Terminal Position
Due to the high efciency 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 inltration,
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 tted less than 2m (80”)
above a balcony, above ground or above a at 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 tted.
Terminal guards are available from boiler suppliers - for all
requirements contact:
Grasslin (UK) Ltd., Tower House, Vale Rise,
Tonbridge, Kent TN9 1TB.
Tel: [phone]. Fax: [phone]
www.tfc-group.co.uk
Ensure that the guard is tted 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 ue 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.
!
DANGER; ONLY USE OPEN FLUE GAS SYSTEMS
WHERE THE EVOMAX AIR INLET KIT IS USED. THE
BOILER CE MARK IS VALID ONLY IF THE APPLIANCE
IS OPERATED WITH THE IDEAL AIR INLET KIT.

GENERAL
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 underoor 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 8.
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 4 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 a current greater than 1.3 amps
inductive, they must be connected via a relay.
When sizing pumps, reference should be made to the table below
which show the boiler resistance against ow rates, to achieve the
required temperature differential.
Flow rates for common systems using either 11ºC, 15ºC or 20ºC
temperature differentials and hydraulic resistances are given in
the table below.
Flowrate (l/min) Hydraulic Resist-
ance (mbar)

Evomax 120 * * 86.0 * * 218
Evomax 150 * * 107.5 * * 230
* Not recommended due to excessive owrates which may cause
erosion of the casting.
Note.
• With the boiler ring at maximum rate, the temperature
differential should not be less than gures quoted in table
above. High ow rates required for lower temperature
differentials could lead to errosion of the heat exchanger water
ways.
• With the boiler ring at minimum rate, the temperature
differential should not be greater than 35oC. Lower ow rates
generating higher temperature differentials will lead to lock out
of the boiler.
• The lower the return temperature to the boiler, the higher the
efciency.
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 ow and return pipes. The bypass should
be tted at least 6m from the boiler, and should use a minimum
size of 28mm pipe. The bypass should be capable of allowing
a minimum ow rate to achieve a temperature differential of no
greater than 35oC at minimum rate.

2 OPEN VENTED SYSTEM REQUIREMENTS
Detail reference should be made to the appropriate standards listed on page 8.
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 specied by Ideal Boilers. The isolation valves should be tted as close to the pump as possible.
The boiler is tted 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 ring of the boiler and subsequent damage to the heat exchanger.

3 SEALED SYSTEM REQUIREMENTS
Note. The method of lling, relling, topping up or ushing sealed primary hot water circuit from the mains for a non-domestic
property is shown below.
1. General
a. Detail reference should be made to the appropriate
standards listed on page 8. The information and
guidance given below is not intended to override any
requirements of these publications or the requirements of
the local authority, gas or water undertakings.
b. The installation should be capable of working with ow
temperatures of up to 90oC and a temperature differential
of up to 20oC.
c. All components of the system, including the heat
exchanger of the indirect cylinder, must be suitable for a
working pressure of 6 bar (87lbf/in2) and temperature of
110oC. Care should be taken in making all connections
so that the risk of leakage is minimised.
d. The boiler is tted 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 ring of the boiler
and subsequent damage to the heat exchanger.
2. Safety Valve
A spring loaded safety valve complying with the relevant
requirements of BS. 6759 Pt. 1 must be tted in the
ow pipe as close to the boiler as possible and with no
intervening valve or restriction. The valve should have the
following features:
a. A non-adjustable preset lift pressure not exceeding 6 bar
(87lbf/in2).
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 0-6 bar must
be tted to the system. The gauge should be easily seen
from the lling point and should preferably be connected at
the same point as the expansion vessel.
IMPORTANT NOTE: If the boilers are installed on to an
Ideal frame & header kit and operated in excess of 3 bar
then all safety relief valves will require upgrading. The
Evomax has a maximum operating pressure of 6 bar.

11 FLUE SYSTEMS
A comprehensive range of ue kits are available from
Ideal Boilers. Examples of horizontal and vertical concentric
and open ue options are demonstrated on the following pages.
Tables are provided with these examples, giving the maximum
extensions which may be added.
For horizontal ues: this is the distance from the ue outlet
centre line on the boiler to the outside wall. Horizontal ues are
not available for Evomax 150.
For vertical ue: this is the distance from the top of the boiler
case to the aperture in the weather collar.
If elbows are to be used, then the equivalent length of that
tting (see page 22) must be subtracted from the maximum ue
extensions allowed for that ue option.
Note: Horizontal terminal resistance includes 1 x 90o elbow.
Worked examples are shown on page 22.
A multiple boiler ue header system is available ‘Ideal Multiline’.
This permits up to 6 Evomax boilers to be connected to a single
ue header with a maximum total output of 600kW.
Other ue header systems should be designed and supplied
by a specialist ue company. BS 6644 and IGE UP/10 provide
guidance on design and the drainage of condensate from ue
stack and headers. Condensate from a ue stack and header
must be collected and drained before entering the boiler.
For room sealed ues Evomax concentric ues must be used.
Note: See Frame 18 for elbow equivalent lengths.
