Check that the overheat thermostat has not tripped -
press button (H) to reset.
If these simple checks fail to solve the problem, or the
problem recurs, consult your service engineer.
B
.
Hot water but no heating
Check that the programmer and room thermostat (if fitted)
are both calling for heat.
If the boiler has been switched off
completely
for some
time the pump may have stuck (if hot water is in use this
should
not
happen as the pump runs for 5 seconds at the
end of each hot water draw-off). A sharp tap on the metal
body of the pump may free it.
If these simple checks fail to solve the problem, or the problem
recurs, consult your service engineer.
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.
D.
Hot water temperature incorrect
If the supply of hot water from the appliance is incorrect
with the domestic hot water tap fully open then the
Response boiler includes a domestic hot water restrictor
handle for you to adjust the water flow rate to obtain the
temperature you require. The restrictor handle is located
beneath the boiler on the left.
BOILER CONTROLS
To shut down the boiler
Set the mains switch (C) to OFF.
When heating is again required, restore the switch to the ON
position.
WARNING.
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating controls (or control (F) )
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'.
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 (G) reads
at
least 0.5 bar
.
Rotate the restrictor handle anti-clockwise
to increase temperature and clockwise to
decrease temperature as indicated on the
handle.

problem recurs, consult your service engineer.
