will then start if beat is
required.
The

position 0
(OFF).
·
On
turning the room thermostat or boiler
thermostat to
a higher setting, the boiler
may
not fire immediately.
This
is
due
to the
integral
"anti-cycling" device
in
the boiler
preventing rapid
on
and
off operation of
the boiler.
[SHUTTING • CARE AND FROST PROTECTION
Note:
If outdoor temperatures
are
low,
the high
efficiency of the
f1ppliance
(energy
saving)
may
lead tovapourformation
on
the ex-
ternal terminal of the
flue duct. This
is
a
normal
physical phenomenon!
Care ami Maintenance
Clean
the outer casing
of
the boiler with a
damp
qloth
and a littlE?
soap.
Do
not use
any
abrasive or solvent
