discharges into an other room or space as
an outhouse or lean-to. It is important that
the position of the terminal allows a free
passage of air across at all times.
The terminal should be located with due
regard for the damage or discoloration that
might occur to building products in the vicin-
ity.
In cold and/or humid weather water vapour
may condense on leaving the fl ue terminal;
the effect of such "steaming" must be con-
sidered.
Pluming may easily occur at the terminal.
Where possible, terminal position which
could cause a nuisance should be avoided.
The minimum acceptable spacing from
the terminal to obstructions and ventilation
openings are specifi ed in Fig. 5.1 .

Wherever practicable to do so, the fl ue should

*** Wall terminals with horizontal discharge less
than 2.5m from a car parking space and less
than 2,1m above the ground.
Wall terminals less than 2,1m above the ground
with horizontal discharge of the fl ue products
across a public footway, or a frequently used
private access route, or a patio (hard surface
area).

Gas supply
The Gas meter is connected to the service
pipe by the local gas region or a local gas
region contractor.

If the gas supply for the boiler serves other
appliances ensure that an adequate supply
is available both to the boiler and the other

appliance when they are in use at the same
time.
Pipework must be of adequate size. Pipes
of a smaller size than the boiler inlet con-
nection should not be used.
Installation pipes should be fi tted in accord-
