INSTALLATION
CONDENSATE &
PRESSURE RELIEF PIPEWORK
CONDENSATE PIPEWORK:
All national and, where appropriate, local
regulations for the discharge and neutralisation
of condensate should be followed.
The condensate pipe must be a minimum of
21.5mmØ polypropylene pipe.
The condensate pipework must fall at least
50mm per metre towards the outlet and should
take the shortest practicable route.
Support the pipe at least every 0.5m for near
horizontal runs .
When a boiler is to be installed in an unheated
location, such as a garage, all condensate
pipes should be considered as external.
EXTERNAL PIPEWORK:
The 21.5mmØ pipe mus not exceed 3 metres
outside the building. If a run greater than 3m is
required, 32mmØ pipe must be used.
Any pipe exposed to windchill or extreme cold
must be 32mmØ.
Protect all external pipes with weather resistant
insulation and box-in, if necessary to reduce the
risk of freezing.
Terminate as close to the ground as possible
(below the grating and above the water level)
while still allowing for safe dispersal of conden-
sate. This will help reduce windchill freezing.
Connection of a condensate pipe to a drain may
be subject to local building regulations.
MAKING IT SAFE:
Condensate pipework must not leak, freeze or
block up.
Condensate traps must be filled before starting
up the boiler to prevent potentially harmful flue
products escaping via the condensate route.
Do not dispose of condensate into water
recovery systems.
Condensate can be discharged into a rain water
hopper which is part of a sewer system carrying
both rain water and foul water.
The pipework must follow one of the options
shown opposite:
a - Internal waste drainage system
b - Soil/vent stack
c - External drainage system
d - External condensate absorbtion point
A - Condensate from the boiler internal con-
densate trap which has a 75mm water seal.
B - Sink.
C - 21.5mmØ polypropylene condensate pipe.
D - Gully.
E - Internal soil and vent stack.
F - 300mm 100mm Ø sealed plastic tube .
G - Ground level.
H - Drainage holes 50mm from base of tube
(12mmØ at 25mm centres) facing away
from building.
I - Limestone chippings.

Unsuitable for clay soil types
PRESSURE RELIEF PIPEWORK:
The pressure relief drain pipe (K) should be at
least 15mm diameter copper pipe and run
downwards away from the boiler and discharge
away from any electrics or other hazard,
preferably to an external drain or soak away.
Pipe (K) should be finished with a partial bend,
near the outlet to face the external wall
(as shown) to help prevent freezing.
IMPORTANT: The pressure relief valve is a
safety device for the boiler and if activated
may discharge boiling water or steam
through the relief valve drain pipe.
Care should be taken when siting the
outlet pipe so that it does not cause an
obstruction or discharge above a window,
entrance or other public access where it
could cause a hazard.
J - Outside wall.
K - Drain pipe.
L - External drain.
