5.5 Condensate Trap
Grant Spira condensing boilers are
supplied with condensate trap. This
trap must be used. No alternative trap
should be used in place of the trap
supplied with the boiler. The 1¼” BSP
female condensate outlet connection is
located at the rear of the boiler.
Fit the 1¼” 311 fitting (supplied) into
this connection. Using the elbow and
pipe (supplied), connect the trap to
the condensate outlet on the boiler, as
shown in Figure 5-1.
A condensate discharge pipe with a
minimum diameter of 38mm (1½”) must
be fitted to the outlet connection at the
base of the trap.
In all cases the overflow pipe (see
Figure 5-1) must be fitted to the trap
and the end left open. This will protect
the boiler from becoming blocked
with condensate in the event of the
condensate discharge pipe blocking or
frozen.
If connecting the condensate
discharge into a waste system
or soil stack, either internally or
externally, a second trap must be
fitted in the condensate discharge
pipe. This trap must provide the
required 75mm water seal. It must be
located between the boiler condense
trap and the connection to the soil
stack, in a position accessible for
checking and cleaning.
5.6 Inspection and Cleaning
of Trap
The boiler condensate trap (and any
second trap fitted) must be checked at
regular intervals (e.g. on every annual
service) and cleaned as necessary to
ensure it is clear and able to operate.
Figure 5-1: Overflow pipe
All condensate pipework must
be adequately protected against
freezing, however if the condensate
pipe is frozen, water will build up
and discharge through the overflow
on the trap.
!
CAUTION
Failure to regularly check and clean
the condensate trap (or traps) may
result in damage to the boiler and
this will not be covered by the
product guarantee.
