designed to minimise cycling and will not
attempt to relight for 3 minutes after the
boiler thermostat has been satisfied (it is
possible to reduce the time to 30 s if
necessary). When the room thermostat
is satisfied the burner will switch off and
the pump will remain running for a further 4 minutes before it stops.
NB : it is possible to override the 3 minute
delay by putting off and on the central
heating selector switch 17.

Temperature regulation for both C/H and

of temperature between 35 and 85°C. The
DHW temperature is limited to 60°C. DHW
and C/H thermistors are identical and
interchangeable.

ROUTINE SERVICING
To ensure continued efficient operation of
the appliance, it is recommended that it is
checked and serviced as necessary at
regular intervals. The frequency of servicing will depend upon the particular installation condition and usage, but in
general, once a year should be adequate.
It is the law that any service work must be
carried out by a competent person such
as your local Chaffoteaux Service Centre,
British Gas or other CORGI registered
personnel in accordance with the current
Gas Safety (Installation and Use)
Regulations.
The service schedule should include
the following operations:
- Check the pressure in the system.
- Check the correct operation of the
appliance.
- Check the correct operation of the gas
controls.
- Check the functions of the safety
controls.
- Check combustion chamber insulation
panels for damage.
- Clean the burner.
- Clean the heat exchanger.
- Check the burner manifold injectors.
- Clean gas and water filters.
- Check expansion vessel charge pressu
re.
- Clean and check operation of safety
valve.
Additional Procedures that may be
necessary:
- Check that the fan blades are clean.
- Check, clean and replace components
as necessary.
- Carry out combustion test utilising the
test points in the flue turret.
SUGGESTED SEQUENCE for SERVICING
Before disconnecting or removing any
parts, isolate the gas and electricity supplies. Ensure that the appliance is cool.
(for detail please see section on Parts
Removal and Replacement)
Preliminary Checks
- Remove outer case
- Check the system pressure is at least
0.8 bar cold
- Check operation of solenoids.
- Check that the burner is extinguished
fully when solenoids are closed in both
DHW and C/H modes.
- Test ionisation functions and check that
lockout occurs by turning off gas tap.
CLEANING THE BOILER
Any cleaning work must only be done
when the boiler is switched off.
Under normal circumstances dusting
should be enough. An occasional wipe
over with a damp cloth will remove any
marks from the casing. On no account
use an abrasive cleaning powder or
liquid.
- Check burner pressure and gas fl
rates.
