PRV DRAIN
The PRV connection, located at the bottom left-hand side of
the boiler, comprises an open ended grommet.
IMPORTANT
The grommet is designed for 15 mm Ø copper pipe.
If possible, preassemble and solder the pipework before
Installing.
If this is not possible the soldering must be more than
100 mm away from the grommet. Make sure the grommet
is not damaged by the heat.
Install the condensate pipe as follows:
1. Make sure that the 15 mm Ø copper
pipe is cut perpendicular to the pipe.
2. Make sure that the pipe is not damaged,
and clean and free from burs.
3. Using pliers put the clip over the
grommet. Continue to hold the clip open.
Note. Do not release the clip until step 5 (see below).
4. Push the copper pipe into the grommet (minimum of
15 mm). Make sure that the pipe is parallel with the
grommet.
5. Below the stop mark on the grommet open the pliers to
release the clip.
6. Make sure that the clip and pipe are attached correctly.
7. Make sure that the PRV discharge pipe is correctly
attached. Make sure that the angle of the pipe run is
sufficient to remove discharged water.
WARNING:
Make
sure that the water or
steam (from the boiler)
is discharged safely.
Hot water or steam is
dangerous and can cause
serious injury, and damage
to electrical systems.
A purpose made
PRV drain pipe is
provided with the
boiler to allow safe
discharge through a
wall to the outside of
the building. This is
particularly relevant to
'high rise' installations
but can be used for all
installations.
Wiring should be 3 core PVC insulated cable, not less than
0.75 mm 2 (24 x 0.2 mm), and to BS 6500 Table 16.
Connection must be made in a way that allows complete
isolation of the electrical supply. The means of isolation
must be accessible to the user after installation.
