GENERAL REQUIREMENTS
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 flue 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 specified in Fig. 5.1.

* Wherever practicable to do so, the flue
should be extended beyond the perim-

** Consideration should be given to adding
protection against condensate to the ad-
jacent structure
*** Wall terminals with horizontal discharge
less than 2.5 m from a car parking space
and less than 2,1 m above the ground.
Wall terminals less than 2,1 m above the
ground with horizontal discharge of the
flue products across a public footway, or
a frequently used private access route,
or a patio (hard surface area).
5.4 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
