1. GENERAL INFORMATION
MTS (GB) Limited support the
initiative. Your installer will give you, and
show you how to use, a logbook which will
give you important information about your
boiler, and heating system. Please have this
logbook to hand whenever you contact a
service engineer or us.
All CORGI Registered Installers carry a
CORGI ID card, and have a registration
number. Both should be recorded in your
boiler Logbook. You can check your installer
is CORGI registered by calling CORGI direct
on :- (01256) 372300.
This is an appliance for the production of
central heating. This appliance must be used
only for the purpose for which it is designed.
The manufacturer declines all liability for
damage caused by improper or negligent use.
Do not allow children or inexperienced
persons to use the appliance without
supervision.
If you smell gas in the room, do not turn on
light switches, use the telephone or any other
object which might cause sparks.
Open doors and windows immediately to
ventilate the room.
Shut the gas mains tap (on the gas meter) or
the valve of the gas cylinder and call your Gas
Supplier immediately.
If you are going away for a long period of
time, remember to shut the mains gas tap or
the gas cylinder valve.
Before any intervention within the boiler it is
first necessary to cut off the electrical power
supply by turning the external switch to
“OFF”.

HELPFUL SUGGESTIONS
To get the most out of your boiler, we have
provided you with some useful advice on
proper use and maintenance:
- Periodically check the system pressure
using the pressure gauge “J”, make sure
that the pressure is between 1.0 and 1.5
bar (the blue part on the gauge) when the
system is off and cool. Consult your installer
for checking and refilling the system if the
pressure value is under 1.0 bar.
J
- The outer panels of the units case must
only be cleaned with a damp cloth. Do
not use abrasive cleaners. The control
panel can be wiped with either a damp
or dry cloth. Spray polishes must not be
used on the control panel surface or
knobs. Care must be taken in preventing
any liquid entering the appliance.
PRACTICAL TIPS
- If the water is very hard, it is
recommended that a scale reducer be
added to the system so as to reduce the
formation of limescale in the boiler heat
exchanger. This will ensure that the
efficiency of the unit remains the same
over time, reducing gas consumption

and maintenance costs.
- If the boiler should be out of use for a
prolonged period, it is recommended
that the electrical power supply be
disconnected and that the external gas
cock be closed. If low temperatures are
expected, the boiler and system pipe
work should be drained in order to
prevent frost damage.
- To improve comfort and take full
advantage of the heat produced by the
boiler, it is recommended that an
external (room) thermostat be installed.
- It is good practice to clean and service
the appliance and central heating
system every year.

The centralised electronic control unit will
ignite the burner, without any manual
intervention but in response to the request
for heating. If, after approximately 10
seconds, the burner has not ignited, the
boiler safety devices will shut off the gas
and the red L.E.D. “F” illuminates. To reset
the ignition system, the reset button “E”
must be pressed and released. Should the
boiler fail to ignite a second time, check
that the external gas cock is open. If the
problem persists, contact an Authorised
Service Centre.
Adjusting the heating
It is possible to set the temperature of the
heating system by adjusting the knob “G”
between 1 and 5 until the stop on the
“ECO” position. This will vary temperature
from approximately 40˚C to about 65˚C.
To obtain a higher temperature it is
necessary to turn the Energy Saving System
(ESS) screw “H” clockwise with a small
coin. The knob is now free to turn to the
MAX position,
which represents
a temperature of
about 80°C.

External (room) thermostat
control
If an external (room) thermostat is installed,
it is recommended that the temperature of
the heating system be set (by means of the
knob “G”) at the “ECO” position. This will
allow the regulation of the external
temperature to operate effectively and
obtain energy efficiency and good
performance
from the boiler. G

3. USEFUL INFORMATION
AND TROUBLESHOOTING
Boiler shutdown situations
The boiler is equipped with safety devices
that intervene in certain situations and shut
it off. Most of these situations are
communicated by means of the red
L.E.D.“F” and at times the user may be able
to remedy them.
Shutdown due to ignition failure
In the event that the automatic ignition of
the burner has failed, the red L.E.D. “F” will
illuminate. In order to reset the ignition, the
button “E” must be pressed and released.

to allow the exchanger to cool down, then
press and release the reset button “E”.
If this situation occurs frequently, contact an
Authorised Service Centre.
Shutdown due to insufficient
system pressure
In the event of insufficient water pressure in
the heating system, a safety device will
shutdown the boiler. Check the system
pressure on the pressure gauge “J” and if
it is less than 0.4 bar refill the system to 1.5
bar (consult your
installer for checking
and refilling the
system). Once the
system pressure is at
J

Should the boiler fail to ignite a second
time, check that the external gas cock is
open. If the problem persists, contact an
Authorised Service Centre.
Shutdown due to overheating
In the event that the safety limit is exceeded
for the temperature of the water in the
boiler’s primary exchanger, the thermostat
shuts off the boiler and the red L.E.D. “F”
illuminates.
To remedy this situation, wait a few minutes

the correct level the boiler will ignite
automatically. If there are frequent drops in
pressure within the system, have a plumber
check the heating system for possible water
leaks.
Temporary shutdown due to
defective discharge of exhaust
fumes
The boiler is fitted with safety devices,
which in the event of a defective discharge
of exhaust fumes, automatically interrupts
the gas supply, thereby shutting off the
boiler.
The shut-off of the boiler is temporary for a
period of about 15 minutes.
Once this time period has passed and the
discharge state of exhaust fumes has
returned to normal, the boiler automatically
turns back on.
Important!
If this situation occurs frequently, contact an
Authorised Service Centre. so that they
may check that the exhaust fumes are
being expelled correctly and that the area
is ventilated properly.
Frost protection
The boiler is fitted with a thermostat which,
in the event that the water temperature
goes below 6°C, the burner turns on at
minimum power until the water in the boiler
has reached a temperature of about 20°C.
This device is only activated when the
boiler is operating perfectly and:
