9 Service and maintenance
9.1 General overview of service and
maintenance
Regular inspection and maintenance of the heating system re-
duces energy consumption and ensures a long life and smooth
operation.
Tests during annual inspection
– General condition of the heating system, visual inspection of
connections and pipes.
– Condensate drain
– Check on the water pressure of the cold water supply
(<6 bar), install/set up the pressure regulator.
– Burner operation and burner settings.
Maintenance work to be carried out annually
– Cleaning the burner components, the combustion chamber
and the heating surfaces.
– External cleaning of the storage tank and sound insulation
hood.
– Replacement of the wearing parts if required).
– Documentation of the maintenance work in the operating
manual.
– Before recommissioning the ROTEX GCU compact after
maintenance work the conditions for commissioning as per
chapter 5.2 must be checked and fulfilled.
9.2 Service and maintenance tasks
Cleaning silencer hood and storage tank
Ɣ The low-maintenance plastic only needs to be cleaned with a
soft cloth and a mild detergent.
Ɣ Do not use any cleaners with aggressive solvents (damage to
the plastic surface may occur).
9.2.1 Checking the connections and pipes
Ɣ
Remove the sound insulation hood.
Ɣ
Inspect all (flue) gas and water carrying components and
connections for leakages and system integrity. If damaged,
determine the cause and replace the damaged parts.
Ɣ Check all components of the flue system for leakage and
damage. Repair damaged parts or replace them.
Ɣ Check all electrical components, connections and pipes.
Repair damaged parts.
9.2.2 Checking and cleaning the condensate drain.
The connection and leakage line of the condensate drain must be
free from impurities.
Ɣ
If a solar system (DrainBack system) is connected and is in
operation, switch it off and empty the solar panels.
Ɣ
Unscrew the overflow hose.
Ɣ Open the condensate drain (connection and drain conduit).
Ɣ
Check that the condensate drain is free from blockages and
clean if necessary.
Ɣ
Visual inspection of container filling level (water level at the
overflow rim).
Ɣ
If necessary, correct the fill level; determine the reason for the
low water level and remedy it.
Have the inspection and maintenance carried out by
authorised and trained heating engineers once a year
and, if possible,
before the heating period . This will
avoid malfunctions during the heating period.
ROTEX recommends an inspection and maintenance
contract to ensure regular inspection and maintenance.
WARNING!
Live parts can cause an electric shock on contact and
cause fatal burns and injuries.
Ɣ
Before beginning the maintenance work,
disconnect the ROTEX GCU compact from the
power supply (fuse, shut off main switch) and
secure against unintentional restart.
CAUTION!
Danger of burning - hot surfaces.
Ɣ Let the burner cool down for a reasonably long
time before maintenance and service work.
Ɣ Wear protective gloves.
WARNING!
Improperly performed work on power or gas lines can
endander life and health and hinder the operation of
the ROTEX GCU compact.
Ɣ
Damage repair to live or gas carrying components
of the ROTEX GCU compact must only be
conducted by heating engineers that are
authorised and approved through the gas or
energy supply company.
UK only!
CAUTION!
If filling or topping up the storage tank is done by
means of the boiler filling and drain valve, a temporary
filling loop must be used with the appropriate backflow
prevention device in accordance with clause G24.2,
Guidance to the Water Supply (Water Fittings)
Regulations 1999.
