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.

GENERAL SAFETY INFORMATION
PRECAUTIONS

6GENERAL
EVOJET steel boilers are triple flue pass, condensing boi-
lers for installation in a boiler room. While they are desig-
ned primarily for central heating purposes, in conjunction
with a suitable storage cylinder they can also be used to
produce domestic hot water.
All parts that come into contact with the combustion
gases are made from titanium stabilised stainless steel
to ensure maximum resistance to the corrosive action of
acid condensation.
The boiler has been designed with the combustion cham-
ber at the top and the smooth pipe tube bundle at the
bottom to optimise heat exchange and energy efficiency
and to maximise the condensing effect.
The EVOJET incorporates two return water connections 7
& 8, this facilitates multiple applications e.g. CH & DHW
and enables the optimum operating efficiency to be
achieved. The system with the lowest return water tempe-
rature should be connected to connection 8 whilst relati-
vely high return water temperature should be connected
to 7. This ensures the maximum condensing output.
The boiler has a high total water content which is diffe-
rentially distributed between its top and bottom sections.
This allows outgoing water to reach the set temperature
quickly while maintaining the condensing effect and the
water heating time around the tube bundle for as long as
possible.
EVOJET boilers feature lightly pressurised combustion
chambers for a smoother burner action, and high tempe-
rature resistant, stainless steel turbulators inside the tube
bundle for maximum burner efficiency.
The boiler body is thoroughly insulated with a layer of
high density glass wool.
The paint finished external panelling is also internally
insulated with a layer of high density glass wool.
The boiler’s front door and the flue gas chamber can be
opened completely to facilitate the inspection, mainte-
nance and cleaning of internal parts and to speed up
servicing in general.
The front door can open in either direction and can be
opened without removing the burner. The door is factory
fitted with hinges on the left, but these can be reversed if
necessary to suit individual installations.

GENERAL
CONTROL PANELS
BURNERS
All EVOJET boilers have been specified for use with a standard IDEAL TECH PRIME control.
The IDEAL TECH PRIME control panel is supplied with the boiler (UIN 212647) this is a single thermostatic control ena-
bling single stage operation and for all modulating applications. The instructions for this control are provided in a separate
manual supplied in the control panel box.
To enable two stage control a Two-Stage burner control kit (UIN 212644) should be requested.
Further control options for modulating burners via a Boiler Management System (BMS) or by an independent modulating
controller may be specified when the burner type is selected.
Oil & Dual Fuel - return water temperature control kit (UIN 215475)
In oil or dual fuel applicatoins the boiler should be prevented from condensing. To achieve this a 'return water temperature
control kit' must be fitted. This kit comprises a return water thermostat that operates a 'Shunt Pump' if the return water tem-
perature is less than 55 deg C.
The EVOJET boilers are designed to operate with Natural Gas, LPG or Oil using pressure-jet or premixed burners.
The burner specification will enable the choice of Two Stage / Fully Modulating & Low NOx operation.
The following burner & control options must be selected at the time of purchase.
Two Stage Burner
To operate a two stage burner the two stage burner control kit should be requested from the tech PRIME manual.
Modulating Burner
To operate a modulating burner the RWF50 modulating controller is required with a control thermistor. This option is selected
when specifying the burner type.
BMS (Boiler Management System) 0-10V
RIELLO Burners:
For operation from a 0-10v BMS signal the RIELLO signal converter should be specified when selecting the burner.
NUWAY Burners:
The burner model which includes the 0-10v converter must be specified.
Oil & Dual Fuel
The optional controls for Oil firing burners are either RWF50 Modulating or 0-10v BMS.
Commissioning
All installations must be commissioned by Ideal to activate warranty provision.

GENERAL
8
For operation of the boiler with oil the following MUST be observed.
• The boiler should be applied on a system that is designed for low temperature hot water (70°C-80°C Flow, >60°C
Return) operation.
• The return water MUST be connected to inlet 8, NOT inlet 7. Inlet 7 should be blanked off.
• The temperature at sensor position 9 must not be less than 60°C.
• The temperature can be maintained above 60°C by using a bypass or shunt pump (to be supplied by installer)
to mix some of the hot flow water with the return water.

IMPORTANT NOTES FOR BURNER
INSTALLATION
Before fixing the burner to the boiler, make sure that:
- The door opens the right way (see the relevant sections
for details on how to reverse the door).
- The length (L) of the burner fixing bolts is less than
(S), i.e. the total depth of the seal, plates and washer.
Longer bolts can cause the door to warp, compro-
mising its ability to seal the boiler hermetically and
permitting the release of combustion fumes.
To ensure correct burner installation, also refer to the
burner’s own manual.

SYSTEM MANAGER
COMMISSIONING
First commissioning must be undertaken by a
combustion specialist appointed by the burner supplier.
Installation, commissioning and maintenance should be
in compliance with BS6644.
Once this has been done, the boiler can be left to
function automatically.
Under certain circumstances, such as after long periods
of disuse, the service engineer responsible for the boiler
may need to re-start it without involving the Technical
Assistance Service.
To do so, perform the following checks and operations:
- Check that the gas cock and heating water cock are
shut.
- While the system is still cold, check that working pres-
sure in the heating circuit is over 1 bar but below the
maximum limit specified for the appliance.
-
Since the control panel incorporates a temperature control
function, make sure that the control panel is switched on.
- Adjust the timer thermostat (if installed) or the temperatu-
re control to the desired temperature (~20° C).
- Make the settings as instructed in the instruction
manual for your control panel.
The burner should now ignite and remain in operation
until the set temperature is reached.
The burner will then switch off and on automatically to
maintain the set temperature without further operator
action.
If any ignition faults or malfunctions occur, the burner
performs a “LOCKOUT SHUTDOWN”. This is shown by
the red button light on the burner and by the warning
light on the control panel.
If a “LOCKOUT SHUTDOWN” occurs, wait about 30
seconds before resetting the burner.
To reset the burner, press the red button light on the
burner and wait until the flame ignites.
Repeat this operation 2 -3 times at the most. If the
problem persists after that, call Ideal Boilers Technical
Assistance Service.
INITIAL START-UP

13
SYSTEM MANAGER
If the boiler is not going to be used for an extended
period of time, perform the following operations:
- Turn the control panel power switch OFF.
- Turn the system’s main power switch OFF.
- Close the fuel cock and heating water cock.
- Drain the central heating circuit if there is any risk of
freezing.
Contact Ideal Boilers Technical Assistance Service
if you encounter any problems in completing the
above procedure.
Use a cloth damped in soapy water to clean the boiler’s
external panelling.
To remove stubborn marks, use a cloth damped in a 50%
mix of water and denatured alcohol or a suitable cleaning
product.
Carefully dry the boiler after cleaning.
Do not use abrasive cleaning pads or powder deter-
gents.
Never clean the boiler without first disconnecting it
from the mains electricity supply by turning the main
power switch and the control panel switch OFF.
The combustion chamber and flues must be clea-
ned periodically by a qualified technician.
THE PERSON RESPONSIBLE FOR SYSTEM OPERATION MUST ENSURE THAT PROFESSIONALLY QUALIFIED
PERSONNEL UNDERTAKE PERIODIC MAINTENANCE AND COMBUSTION EFFICIENCY MEASUREMENTS.
THIS SHOULD BE CONDUCTED IN COMPLIANCE WITH BS6644.

INSTALLER
EVOJET steel boilers must be installed in a dedicated
boiler room, with adequately sized vents, in compliance
with BS6644.
If at all possible, the boiler should be installed on a raised
base to stop the burner fan sucking up dust and to facili-
tate installation of a condensate drain system.
The boiler condensate drain must be located above the
height of the lid of the system’s condensate neutraliser.
The gas supply pipe must be installed in such away that
the boiler’s panelling can be removed and the front door
opened without having to remove the burner.
When installing the boiler, allow sufficient space
around it to access all safety and control devices
and to permit easy maintenance.
If the specific weight of the gas supply to the bur-
ner is greater than the specific weight of air, install
all electrical parts at least 500 mm above floor
level.
Do not install the boiler outdoors. It is not designed
to work outdoors and is not fitted with the necessa-
ry automatic anti-frost systems to do so.

WATER IN CENTRAL HEATING SYSTEMS
WATER IN CENTRAL HEATING SYSTEMS:
INSTRUCTIONS FOR THE DESIGN, INSTALLATION AND MANAGEMENT OF CENTRAL HEATING SYSTEMS
1. Chemical and physical characteristics of water
The chemical and physical characteristics of water used in central heating systems must conform to the requirements of
EN 14868 standard and to the following tables:
(*) values for water in system after 8 weeks of functioning
General note on water used to top up systems:
- If softened water is used to top up a system, 8 weeks of functioning after topping up, verify that the water in the system
respects the above limits, in particular for electrical conductivity.
- This check is not necessary if demineralised water is used to top up the system.
2. Central heating systems
b Do not use automatic filling devices to add water to central heating systems. Use a manual device instead and
record top-ups in the system service book.
b If a system comprises a number of boilers, when that system is first put into service, make sure that all the boilers
function simultaneously or on a short interval rotation basis in order to evenly distribute initial limescale deposits.
b When you finish installing a system, always flush it out to remove installation residues.
b Water used to fill a system for the first time and water used to top it up must always be filtered (using synthetic or
metal mesh filters with a filtration rating of no less than 50 microns) to prevent sludge from forming and triggering
deposit corrosion.
b Before re-filling an existing system, clean and flush it out thoroughly. Only fill the boiler after the central heating
circuit has been thoroughly flushed out.
2.1 New central heating systems
Initial filling of the system must be performed slowly. In theory, once filled and bled of all air, a heating circuit should not
need topping up.
Systems should also be operated at maximum working temperature the first time they are started up, in order to facilitate
de-aeration. (Gas is not released from the water at low temperatures.)
2.2 Reconditioning old central heating systems
If a boiler has to be replaced, do not refill the entire central heating circuit if the quality of water in it conforms to requi-
rements. If the quality of water fails to conform to requirements, either recondition the old water or separate the water
circuits (water in the boiler circuit must conform to requirements).

3. Corrosion
3.1 Deposit corrosion
Deposit corrosion is an electro-chemical phenomenon caused by the presence of foreign bodies (sand, rust, etc.) in the
water mass. These solid substances generally form deposits (sludge) in the bottom of the boiler, in the tube heads and
in the joins of tube bundles.
These parts of the boiler can therefore be affected by micro-corrosion caused by the electrochemical potential difference
created between the metal parts in contact with impurities and other metal parts around them.
3.2 Stray current corrosion
Stray current corrosion is caused by the different electrical potentials of the water in the boiler and the metal body of the
boiler or piping. Stray current corrosion is easily identified by the regular tiny conical holes it leaves.
b All metallic parts should be grounded by an efficient earth cable for this reason.
4. Eliminating air and gas from central heating systems
If oxygen enters a circuit continuously or even intermittently (e.g. in under-floor heating systems whose pipes are not
protected by impermeable synthetic sheaths, in circuits with open expansion vessels, or in circuits that require frequent
top-ups) always separate the boiler’s water circuit from the central heating circuit.
Mistakes to avoid and precautions
From what has been said above we can see that it is essential to avoid two main factors that could lead to corrosion.
These are contact between system water and air and the continuous addition of fresh water to the circuit.
To eliminate contact between system water and the air (thus avoiding oxygenation of the system water), we need to:
- ensure that the expansion vessel is a closed vessel, and of the correct size and pre-charge pressure (the pressure to
be checked periodically);
- ensure that the system is always kept at a pressure higher than atmospheric pressure at all points (including the pump
suction side) and under all operating conditions (precisely because the seals, gaskets and joins in a water circuit are
designed to resist pressure from within, but not to resist a vacuum within);
- ensure that no part of the system is made from materials that are permeable to gases (e.g. plastic pipes with no oxygen
barrier destined for under-floor heating systems).
b Finally, never forget that boiler failures caused by encrustation and corrosion are not covered under the
terms of the warranty.
5. Water Treatment
CENTRAL HEATING
The EVOJET range of boilers have a stainless steel heat exchanger.
IMPORTANT.
The application of any other treatment to this product may render the guarantee of Ideal Boilers Invalid.

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. BS 7593:2006 details the steps necessary to
clean a domestic heating system.
3. In hard water areas, treatment to prevent lime scale may
be necessary - however the use of articially softened
water is NOT permitted.
4. Under no circumstances should the boiler be red before
the system has been thoroughly ushed.
