appliances are installed by a competent person in accordance
with the current issue of the above regulations.
Maintenance
To ensure the continued efficient and safe operation of the boiler
it is recommended that it is checked and serviced at regular
intervals. The frequency of servicing will depend upon the particular
installation and usage, but in general once a year should be
enough.

care imposed on the owner of the property by the current issue of

Gas Leak or Fault
If a gas leak or fault exists or is suspected the boiler must be turned
off also the electrical supply. Advice/help should be obtained from
your installation/servicing company or the local gas company.
Protection Against Freezing
If the 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 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 you have a sealed water system you should contact your
installer/servicing company as a sealed water system should only
be drained, refilled and pressurised by a competent person.

The boiler must be positioned so that at least the minimum
operational and servicing clearances are provided, see diagram

If fixtures are positioned close to the boiler they should be made
removable for access to pipework.
Enough space must be left in front of the boiler for servicing.
Boiler in a Compartment

ventilation must be provided and kept clear.
Do not use the enclosed space for storage.
