2. Close all the water isolating (CH and DHW) valves on the
boiler inlet.
3. To drain the central heating circuit :
a. Attach a length of hose to the drain point and open the
drain valve.
b. Remove diverter valve actuator (Refer to Frame 62).
c.
To ensure the boiler and heat exchanger are fully drained,
the diverter valve must be held in mid-position. Using a
suitable tool depress the plunger in the diverter valve
housing by approximately 3mm (1/8") and hold until
draining is complete.
d. Replace diverter valve actuator.
4. To drain the domestic hot water circuit . As there is no direct
drain for the domestic hot water circuit, depending on the
location of the boiler, opening the lowest hot water tap may
drain this circuit. However it must be noted that some residual
water will be experienced during replacement of components.
5. After replacing any component on the boiler, close the drain
valve, remove the hose and open all system isolating valves
(re-pressurise as appropriate with filling loop provided)
before proceeding to check operation of the boiler.
6. Check operation of the boiler. Refer to Frame 52.
