7. Because the flue gases and terminal are at very
low temperature it is not necessary to fit a
Terminal guard to protect against burns. If a
guard is required for any other reason the
following is recommended.
For the Concentric Terminal:
Model K3 6.5 x 11 (plastic coated) (GC No 393554)
For the Twin Flue Terminal:
Model B (black plastic coated).
For the Single Flue Terminal:
Model H (black plastic coated).
All are available from:

IMPORTANT.
It is absolutely ESSENTIAL to ensure, in practice,
that products of combustion discharging from the
terminal cannot re-enter the building, or any other
adjacent building, through ventilators, windows,
doors, other sources of natural air infiltration or
forced ventilation/air conditioning.
If this should occur, the appliance MUST be turned
OFF IMMEDIATELY and the Local Gas Region
consulted.

Air Supply

It is NOT necessary to have a purpose provided air
vent in the room or internal space in which the boiler
is installed.
Where the boiler is installed in a cupboard or com-
partment no air vents are required. However the
User may wish to ensure that is ventilated to provide
air circulation.

Water Supply

The central heating system should be in accordance
with the relevant recommendations given in
BS.6798, BS 7593:1992 and, in addition, for
smallbore and microbore systems - BS.5449:1.
The domestic hot water system, if applicable, should
be in accordance with the relevant recommendations
of BS.5546.
Copper tubing to BS 2871:1 is recommended for
water carrying pipework.
The hot water storage cylinder MUST be of the
indirect type and should preferably be manufactured
of copper.
The hot water cylinder, & ancillary pipework, not
forming part of the useful heating surface should be
lagged, to prevent heat loss and any possible
freezing, particularly where pipes run through roof
spaces and ventilated underfloor spaces.
Draining taps MUST be located in accessible posi-
tions, which permit the draining of the whole system,
including boiler and hot water storage vessel. Drain-
ing taps should be at least ½ in. nominal size and be
in accordance with BS.2879.

Condensate Drain

Refer to Fig. 2, and 12.
A condensate drain is provided on the boiler, this
drain must be connected to the household drainage
point, or soakaway on site. All pipework and fittings
in the condensate drainage system MUST be made
of plastic. Refer to British Gas publication "Guidance
notes for installation of domestic condensing boilers"
No other materials may be used.
The drain outlet on the boiler is :
Polypipe, 21.5mm pushfit overflow pipe.
