Open one or more hot water taps to drain the
domestic hot water circuit.
Disconnect the cold water inlet connection to the
boiler.
Clean and inspect the filter, replace if necessary
as described in (18.20).
Re-fit the filter and reinstate the cold water inlet
connection to the boiler, fit new gasket as
required.
Fully open the isolating valve on boiler's cold
water inlet and check for leaks.
18.12 On completing the service reassemble the boiler
components in reverse order of removal, ensuring that
all component joints and gaskets are sound. Any
damaged seal or gasket must be replaced.
18.13 Reinstate the boiler's electrical and gas supplies
and check for gas soundness and correct boiler
operation.
CAUTION!
While there are no substances harmful to health
contained within this appliance, some component parts
of the boiler (insulation pads, gaskets and rope seals)
are manufactured from man made fibres. When
damaged or broken these fibres may cause a
temporary irritation. High dust levels may irritate eyes
and upper respiratory system. It is important therefore,
that sensible precautions are applied when exchanging
components.
19. Component Replacement
19.1 Ensure that both the electrical and gas supplies
to the boiler are isolated before replacing any
component part.
19.2 To prevent the need to drain the entire heating
system when replacing the boiler's integral pump,
expansion vessel, safety relief valve and pressure
sensor, the boiler’s hydraulic circuit may be isolated
from the central heating circuit by closing the boilers
isolation valves. Opening the discharge valve will then
drain the boiler’s hydraulic circuit. Note clean the
valve seat to ensure it seals before re-filling the
boiler.
19.4 Domestic hot water sensor
The domestic hot water sensor is located on the left
side of the hydraulic block’s hot water side. (Figure
32)
Carefully disconnect the leads from the sensor.
ELECTRICAL
CONNECTIONS
Remove the sensor using a 13mm spanner.
Fit the replacement sensor ensuring the washer is
correctly fitted. Re-fit the leads to the replacement
sensor
19.5 Central heating sensor
DOMESTIC HOT
WATER SENSOR
The c/heating sensor is located on left side of the
combustion chamber on the outlet of the primary
heat exchanger. (Figure 33)
Unclip the sensor from the pipe.
Disconnect the leads from the sensor.
