GENERAL NOTES
VENTILATION
This is a room sealed appliance and
does not require any air for combustion
from inside the property. If the appliance
is fitted into a cupboard or a compart-
ment is built around the appliance after
installation, then the compartment must
be separated from the boiler space by a
perforated non-combustible partition as
described in BS 6798.
Notwithstanding the requirements of BS
6798 and BS 5440 there is no need for
ventilation openings to be provided in
the compartment because of the low
heat loss from the appliance casing, if
the clearances shown are maintained.
Do not operate the appliance if the flue
terminal fitted on the outside wall or roof
is obstructed or damaged.
PUMP ANTI-SEIZURE
If there has been no heating demand for
24 hours the boiler will run the system
pump for a few seconds to reduce the
possibility of pump seizure during long
periods of inactivity, which is usually
more frequent during the summer
months.
