Before commencing any service/maintenance work, the following tasks must be undertaken.
The results of the Inspections undertaken above must be acted upon, and all discrepancies should be re-
corded on the Service Report and brought to the Client / End User’s attention.
Undertake any maintenance, and if necessary any preventative maintenance, that’s required.

As part of the Routine Service Inspection, certain areas of the boiler need to
the checked and cleaned as necessary.
a) Turn the boiler OFF at the ON/OFF switch and electrically isolate the boiler
by removing the plug or fuse from the boiler supply.
b) Turn o the gas at the boiler Isolation tap, tted by the installer, adjacent
to the appliance.
c) Remove all Electrical connections from the Fan Assemble, One cable on
the Procon , & models, two cables on the Procon model.
d) Disconnect the Earth Lead, HT Cap and Lead from the Ignition Electrode.
e) Procon ONLY, Undo the long Hexagon Bar at the top of the Heat Exchanger
and gently rotate the heat exchanger forward, pivots to the left, See Fig .a.
f) Disassemble the burner by removing the six M nuts around the burner
door, using a mm Spanner. Pull the burner forward and remove from
the heat exchanger. Gently put to one side.
g) Once access has been gained to the combustion chamber and front section of
the heat exchanger, visually inspect the heat exchanger coils, See Fig .b.
It is usually only necessary to clean the front section of the heat exchanger.
If server deposits are found, the rear section of the heat exchanger should
also be checked and cleaned, which will necessitate the removal of the
heat exchanger from the boiler.
If any coils appear to be signi cantly dis-coloured, then a blockage of either
scale, magnetite, or general system debris has occurred which will have al-
lowed excessive overheating to have occurred within the coil.
If dis-colouration has occurred, then specialist de-scaling of the heat exchanger will be required, however, stress
cracking may have occurred, and the heat exchanger may become porous following the de-scale works.
h) If the heat exchanger has not su ered from dis-colouration, as ‘Item g’ above, then a Standard Service can
be undertaken. Using a natural bristled brush ONLY, remove the worst of the mineral/debris buildup.
With the use of the dissolved Procon Combustion Chamber Cleaning Granules, spray the solution onto
the heat exchanger surface and leave for approximately minutes. This will help to remove any stubborn
mineral deposits. Finally brush the heat exchanger whilst rinsing thoroughly with copious amounts of
fresh water. Procon Combustion Chamber Cleaning Granules are available from RVR Boilers Spares depart-
ment. A STEEL OR PVC BRUSH MUST NOT BE USED TO CLEAN THE HEAT EXCHANGER.
a) Ask the end user about any problems with the oper-
ation of the boiler unit and note their comments.
b) Check the water pressure of the installation.
h) Utilizing the instructions in Section ., review
the LMU Operating Error Codes, and note the re-
corded codes onto the Service Report.
c) Remove the boiler casing and visually inspect all
pipe and water joints for signs of leakage.
d) Inspect the top of the casing and the top of the
heat exchanger for signs of water ingress from the
outer mm ∅ Air Pipe.
e) Run the unit in Commissioning Mode HIGH FIRE;
with the use of a ue gas analyzer record the CO
level. See section ..
f) Run the unit in Commissioning Mode LOW FIRE;
with the use of a ue gas analyzer record the CO
level. See section ..
g) Listen to the sound of the combustion fan.
h) Utilizing the instructions in Section ., review
the LMU Operating Error Codes, and note the re-
corded codes onto the Service Report.
i) Undertake a System Water Analysis to check the
concentration level of the Water Treatment, and
note the level onto the Service Report.
j) Check the ue route including the terminal po-
sition for conformity with prevailing regulations,
and trim back any foliage that may be around the
terminal.
k) Check the plant room/compartment ventilation
system for conformity with prevailing.
l) Check the Pressure (Safety) Relief Valve size, rat-
ing and orientation, for conformity with prevailing
regulations.
