When there is a need for hot water tank
reheating while the heating is on. The
heating will be interrupted momentarily
while tank is reheated. The boiler will
switch back automatically to heating
when the tank is at temperature.
Note: If the boiler has been turned off for
some time the first attempt to light it may
result in a lockout . 22 . If this happens
press the reset button 23 and the boiler
will light.
Domestic Hot Water Mode
To be able to supply hot water, the selector switch 15 must be in either on
or
position. This will be confirmed
20
by the green indicator light
When the aquastat of the tank is on, it
activates the DHW flow switch 44 and
allow the 3 way valve 42 to move to the
HW position. The pump can now circulate primary water heated by the main
heat exchanger through the tank heat
exchanger.
The first stage solenoid 31 (blue) and
security solenoid 30 (grey) open together
to allow gas to the burner. The ignition
sequence begins and a continuous high
speed spark ignites the gas. As soon as
a flame is detected the orange indicator
bulb
21 will light and the second stage
solenoid 32 (black) opens to allow the full
gas rate. If a flame is not detected, after
8 seconds, the security solenoid closes
and shuts off the gas. The red lockout
indicator bulb
22 will light. The water
flow temperature is controlled by the
central heating control thermistor 37.
When the tank is at temperature, the
burner is extinguished and the pump
stops. The boiler will now stay in the hot
water mode for three minutes.
Priority will be given to a demand for hot
water tank reheating. This will interrupt
the central heating for the duration of hot
water tank reheating.
Central Heating Mode
To be able to supply heating, the selector
position.
switch 15 must be on
This will be confirmed by the green indi20.
cator light
When there is a demand for heating
(either from the room thermostat or the
clock) the pump starts. If the boiler temperature control is calling for heat and
primary flow rate over 4 ltr/min, the central heating flow switch operates allowing
the ignition sequence to begin. The first
stage solenoid 31 (blue) and security
solenoid 30 (grey) open together to allow
gas to the burner. The ignition sequence
begins and a continuous high speed
spark ignites the gas. As soon as a flame
is detected the orange indicator bulb
21 will light. After 45 seconds the second
stage solenoid 32 (black) opens to allow
the full gas rate. If a flame is not detected, after 8 seconds, the security solenoid
closes and shuts off the gas. The red
lockout indicator bulb
22 will light.
The central heating flow temperature is
controlled by the central heating control
thermistor 37. The boiler has been
designed to minimise cycling and will not
attempt to relight for at least 3 minutes
after the boiler thermostat has been satisfied. When the room thermostat is satisfied the burner will switch off and the
pump will remain running for a further 3
minutes before it too stops.
NB
It is possible to override the 3 minute
delay by pressing the RESET button 23.
Lock out procedure
Flame disappearance :
When the ionisation electrode 28 does
not detect flame presence. The orange
indicator lamp 21 extinguishes. A lighting
cycle starts. If a flame is not detected
before 8 seconds, the grey security solenoid 30 and the blue 1/3 solenoid 31will
close. The lock out red indicator 22
lights, the pump 35 runs and the 3 way
valve 42 stays in its position.
After a few seconds, it will become possible to reset the boiler by pressing the
reset button 23.
Overheat detection :
If an overheat is detected by the sensor
13, the grey security solenoid 30 and the
blue 1/3 31 closes, the orange indicator
lamp 21 extinguishes. The ignitor is
energised for 8 seconds and the red
lockout indicator 22 ligths. If the burner
cannot relight the boiler will go to lockout.

REGULATION
Temperature regulation for both C/H and
DHW circuits are controlled by 2 thermistors. The C/H knob allows the adjustment
of temperature between 35 and 85°C. The
DHW temperature is limited to 60°C. DHW
and C/H thermistors are identical and
interchangeable.

FLOW SWITCHES
Flow in both D.H.W. and Heating circuits
are detected by 2 flow switches. A piston
with a magnet at the top operates a REED
switch. The piston is lifted by flow rates
listed below :
Flow rate threshold :
D.H.W.
120 l/h ±20 l/h
C/H 250 l/h ±20 l/h
AIR PRESSURE SWITCH
The air flow rate is detected by a pressure
differential created by a venturi located in
the flue duct.

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.
- Check burner pressure and gas flow
rates.
- 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.
The service schedule should include
the following operations:
(for detail please see section on Parts
Removal and Replacement)
- Check the pressure in the system by
checking the reading on the pressure
guage (No. 18 Control Panel - Page 3).
- Check the correct operation of the appliance (see Page 4 - Domestic Hot Water
Mode and Central Heating Mode).
- 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 pressure.
- Clean and check operation of safety
valve.
Preliminary Checks
- Remove outer case
- Check the system pressure is at least
0.7 bar cold
- Check operation of 1/3 and 2/3 solenoids.
- Check that the burner is extinguished fully
when both solenoids are closed in both
DHW and C/H modes.
- Test ionisation functions and check that
lockout occurs by turning off gas tap.
- Whilst boiler is operating, check operation
of primary flow switch by closing heating
flow valve and by pass screw (turn clockwise) noting the number of turns so that it
may be reset correctly.
Additional Procedures that may be
necessary:
