INTRODUCTION
**
Do not add cupboards, shelves etc. to restrict the space around the boiler.
VENTILATION
This is a room sealed boiler and does not require any air for combustion from inside the property. If the boiler is fitted into a cupboard or a compartment is built around the boiler 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 boiler casing, if the clearances shown are maintained.
Do not operate the boiler 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.
