CAUTION. If the back boiler is to be out of use for any long
period of time during severe weather conditions we recommend
that the whole of the system, including the back boiler be
drained off to avoid the risk of freezing up.
If an immersion heater is fitted in the domestic hot water cylinder
make sure that it is switched off.
If in doubt your installation/servicing company or the local gas
undertaking should be contacted

This appliance is fitted with a flue blockage safety device which
will shut down the appliance in the event of abnormal flue
conditions. This device is NOT a substitute for an independently
mounted Carbon Monoxide detector. If it shuts down frequently
for no apparent reason the first things that must be checked are
the chimney and air inlets into the room.
Any problems found must be put right, by a competent person,
