Faults
A. No heating or hot water
Check that gas and electricity are available at the boiler and
that all switches are on.
Check that the system water pressure gauge (E) reads
at
least 0.5 bar
.
Check that the overheat thermostat has not tripped.
Remove cover and press button (D) to reset.
Turn the main switch (A) to OFF (O) position, wait 5 seconds
and return to desired setting.
B
.
Hot water but no heating
Check that the programmer and room thermostat (if fitted)
are both calling for heat.
C. Heating but no hot water
Check that
cold
water does flow out of the hot taps at a
minimum rate of 3.5 litres per minute (or 1 pint in 10
seconds or less).
If not, look for stop valves not fully open.
If these simple checks fail to solve the problem, or the
problem recurs, consult your service engineer.
To shut down the boiler
Set the main switch (A) to OFF (O).
When heating is again required, restore the switch to the HOT
WATER or HEATING & HOT WATER.
Frost
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating control (B) at a reduced
temperature setting.
For longer periods, the entire system should be drained -
including the domestic water supply .
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF by selecting the OFF
programme at the time control.
The mains supply should be left switched ON.
If in doubt, ask your installer.
To relight the boiler
Repeat the procedure detailed in 'To light the boiler'.
