P From wall face
Q From, above or to side of an
opening
* Wherever practicable to do so, the flue
should be extended beyond the perim-
eter of the balcony
** 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).

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 connec-
tion should not be used.
Installation pipes should be fitted in accord-
ance with BS 6891 and the complete instal-
lation should be tested for tightness.
For Ireland (IE), refer to I.S.813.2002.
5.5
Air supply
The room in which the boiler is installed does
not require a purpose provided air vent.

Ventilation
If installed in a cupboard or compartment, it
is not necessary to provide additional ven-
tilation for cooling for this particular prod-
uct. However consideration must be given
to clearance requirements for maintenance
(section "Precautions for installation" to
page 31) and under no circumstances must
stored articles be allowed to come into con-
tact with the boiler or flue pipe.
5.7
Condensate drain
Ensure that the condensate discharge com-
plies with the national or local regulations in
force. The condensate pipe must be fitted in
accordance with Building Regulations.
Drain pipe material should be resistant to
acid as the condensate is slightly acid with a
pH less than 6.5. The boiler includes a trap
(21on page 16) that prevents the combus-
tion products entering the drain.
The boilers incorporate a condensate trap
with a 75 mm seal to comply with BS 6798:
2008.
The schematic diagrams of possible con-
nections are given in Fig. 5.2 and Fig. 5.3.
The length of the condensate pipe should be
kept to a minimum, any external pipe should
not be more than 3 m in 32 mm pipe and
insulated to prevent freezing.
To avoid condensate being trapped:
• the drain pipe should be run with a fall of at
least 2.5° (45 mm/m) away from the boiler;
• the number of bends and joints should be
kept at minimum;
• the drain pipe should be adequately fixed
to prevent pipe sagging.
If a part of the drain pipe runs externally this
part should be kept as short as possible and
protected to reduce the risk of freezing.
