EMARKS
To ensure the validity of the 5 Year Guarantee, the boiler
must
be
serviced annually by a CORGI registered gas engineer.
Provided the boiler was registered within the terms stated on the
guarantee card, MTS (GB) Limited will write to the householder as
the boiler becomes due for it’s annual service.
The requirements stated in the letter must be adhered to in order to
ensure the continuation of the 5 year guarantee.
See Section 10 for annual maintenance requirements.
Note: Failure to comply with the annual service
requirements will result in the 5 year guarantee
becoming void.
CLEANING THE EXHAUST SIDE
Remove the combustion chamber inspection hatch (see section
7.3.5). Check that the exhaust passages between the blades of the
block are free; if there are deposits present, wash the blades with
compressed air, water or a vinegar-based detergent.
NOTE: it is possible to use a brush in order to mechanically remove
the residues.
Use of detergents:
-
soak the blades well
-
allow the detergent to act for about 20 minutes
-
rinse with a strong jet of water to remove the deposits (the
control panel must be kept closed)
-
make sure that there are no traces of detergents in the
exchanger.
CLEANING THE WATER SIDE
Use detergents that dissolve CaCO3. Leave to act for a short time
(in order not to damage the aluminum) and then rinse. Make sure
that the detergent does not remain inside the exchanger.
To clean the condensate trap it is simply necessary to unscrew the
lower part of the condensate trap and clean it. Lastly, fill it with water
and replace the stopper.

After having carried out the maintenance operations, fill the
heating circuit to a pressure of approx. 1.5 bar and release the
air from the system. Also fill the domestic hot water system.
-
Place the boiler in operation;
-
If necessary, release the air again from the heating system.
-
Check the settings and the correct functioning of all the
control, regulation and monitoring parts;
-
Check the seal and the correct functioning of the system for
expelling fumes/drawing of combustion air;
-
Check that the boiler ignites properly and carry out a visual
check on the burner flame;
-
Check the CO
2
values are correct (see Section 3.6.3)
IMPORTANT!!
Every time that the combustion chamber cover or the
primary heat exchanger is removed from the boiler, the
combustion chamber seal must be checked and where
necessary replaced (code: 65102217). The silicone
grease provided with the gasket must be spread
around the area the gasket fits to ensure an airtight
seal.
Only the grease provided must be used, however,
should more grease be needed it must have a
temperature range of between –40 deg C and +200
deg C”
D
O NOT OPERATE THE BOILER WITH THE FRONT COMBUSTION
CHAMBER PANEL REMOVED
! F
AILURE TO OBSERVE THIS WILL
DAMAGE THE FAN AND AIR PRESSURE SWITCH AND WILL
INVALIDATE ANY WARRANTY
.
IMPORTANT!!
If the boiler is not to be used for a prolonged period, the
condensate trap should be filled before operating the
boiler. A shortage of water in the trap will temporarily
risk flue gasses escaping into the room.
