7.5 Ventilation of Compartments (Fig. 14)
1. Where the boiler is installed in a cupboard or
compartment, air vents are required (for cooling
purposes) in the cupboard or compartment at high and
low level which may communicate with a room or direct
to outside air.
NOTE: Both air vents must communicate with the same
room or both be on the same wall to outside air
2. Detailed recommendations for air supply are given in
BS 5440: Part 2.
3. An existing cupboard or compartment may be used,
provided that it is modified for the purpose.
Recommendations for air supplies and details of
essential cupboard compartment design are given in
BS 5440: Part 2.
7.6 Gas Supply
1. The gas installation should be in accordance with
BS6891.
2. The connection to the appliance is a ½in BSPT internal
threaded connection located at the rear of the gas
service cock (Fig. 15).
3. Ensure that the pipework from the meter to the
appliance is of adequate size. (22mm pipework must be
connected to the appliance gas service cock. This
should extend for at least 3 meters back towards the
gas meter).
Do not use pipes of a smaller diameter than the
boiler gas connection.
7.7 Electrical Supply
1. External wiring must be correctly earthed, polarised and
in accordance with current l.E.E. WIRING
REGULATIONS.
2. The mains supply is 230V ~ 50Hz fused at 3A.
NOTE: The method of connection to the electricity supply
must facilitate complete electrical isolation of the appliance.
Connection may be via a fused double-pole isolator with a
contact separation of at least 3mm in all poles and servicing
the boiler and system controls only.
7.8 Condensate Drain
NOTE: Ensure the discharge of condensate complies with
any national or local regulations in force.
1. The condensate outlet terminates in a 1" BSP nut and
seal for the connection of 21.5mm (¾in) plastic
overflow pipe which should generally discharge
internally into the household drainage system. If this is
not possible, discharge into an outside drain is
acceptable.
2. The pipe should run internally as much as possible and
with a 10º (1 in 6) fall to dispose of condensate quickly
to avoid freezing.
