The evo HE is a wall mounted, room sealed, condensing
combination boiler, featuring full sequence automatic spark
ignition and fan assisted combustion.
Due to the high efficiency of the boiler, condensate is produced
from the flue gases and this is drained to a suitable disposal point
through the plastic waste pipe at the lower rear of the boiler. A
condensate 'plume' will also be visible at the flue terminal.
The evo HE is a combination boiler providing both central heating
and instantaneous domestic hot water.

Current Gas Safety (Installation & Use)
Regulations or rules in force.
In your own interest, and that of safety, it is the law that this boiler
must be installed by a Gas Safe Registered Engineer, in
accordance with the above regulations.
In IE, the installtion must be carried out by a Registered Gas
Installer (RGII) and installed in accordance with the current
edition of I.S. 813 "Domestic Gas Installations", the current
Building Regulations and reference should be made to the
current ETCI rules for electrical installation.

Electricity Supply

This appliance must be earthed.
Supply: 230 V ~ 50 Hz. The fusing should be 3A.
Connection must be made in a way that allows complete isolation
of the electrical supply such as a double-pole switch, having a
3mm (1/8") contact separation in both poles, serving only the
boiler and system controls. Alternatively, a 3-pin UNSWITCHED
socket may be used. The means of isolation must be accessible
to the user after installation.

Important Notes

This appliance must not be operated without the casing
correctly fitted and forming an adequate seal.
If the boiler is installed in a compartment then the
compartment MUST NOT be used for storage purposes.
If it is known or suspected that a fault exists on the boiler then
it MUST NOT BE USED until the fault has been corrected by
a Gas Safe Registered Engineer or in IE a Registered Gas
Installer (RGII).
Under NO circumstances should any of the sealed components
on this appliance be used incorrectly or tampered with.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they
have been given supervision or instructions concerning use of
the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play
with the appliance.
All Gas Safe Registered Engineers carry a Gas Safe Register ID card, and have a registration number. Both should be recorded
in the Benchmark Commissioning Checklist. You can check your installer by calling Gas Safe Register direct on 0800 4085500
Ideal Stelrad Group is a member of the Benchmark scheme and fully supports the aims of
the programme. Benchmark has been introduced to improve the standards of installation and
commissioning of central heating systems in the UK and to encourage the regular servicing of all
central heating systems to ensure safety and efficiency.

Clearances of 165mm (6
(1/4") at the sides and 450mm (17 3/4") at the front of the boiler
casing must be allowed for servicing.
The minimum front and bottom clearance allowed when built into
a cupboard is 5mm.
To light the boiler. Refer to Frame 1
If a programmer is fitted refer to separate instructions for the
programmer before continuing.
1. CHECK THAT THE ELECTRICITY SUPPLY TO THE BOILER
IS OFF.
2. Set the mains ON/OFF switch (A) to OFF and the DHW
thermostat knob (J) and CH thermostat knob (F) to maximum.
3. Ensure that all DHW taps are turned off.
4. Switch ON the electricity supply to the boiler and check that
all external controls, e.g. programmer, room thermostat etc.,
are ON.
5. Set the mains ON/OFF switch to ON.
The boiler will commence the ignition sequence, first supplying
heat to preheat the domestic hot water and then to the central
heating, if required.
Note. In normal operation the control unit display (C) will show
codes:
Standby - no demand for heat.
DHW being supplied.
Boiler frost protection - boiler will fire if temperature is
less than 3 degrees C.
During ignition, the LED (E) will flash.
During normal running the LED (E) will remain illuminated.
Note. If the boiler fails to light after 3 attempts this fault code
will be displayed.
Press the reset button (D) for 2 seconds then release. The boiler
will repeat the ignition sequence. If the boiler still fails to light
consult a Gas Safe Registered Engineer or in IE a Registered
Gas Installer (RGII).
O p e r a t i o n
Winter conditions - i.e. CH and DHW required.
The boiler will fire and supply heat to the radiators but will give
priority to DHW on demand.
The DHW preheat will operate as described under 'Summer
