Wall mounting (Fig. 2/3/4)
There are two ways in which the continuous-flow heater can be mounted
on the wall:
• Using the mounting bolt. Unevenness in the wall up to a depth
of 25 mm can be compensated for.
• Making use of the holes that were drilled for the old heater:
Use the mounting template to establish whether the existing
holes line up properly.
The following describes the installation procedure using the mounting
bolt.
Marking the point for mounting the heater and selecting
the opening for the connecting cable (Fig. A)
WARNING:
Important!
Make sure that the connecting cable is isolated from the mains
electricity supply!

• Place hole 3 in the mounting template over the cold-water inlet.
• Select the most suitable hole through which the connecting cable
is be fed. The connecting cable must pass through one of the six holes
marked 14.... Terminal BZ45Z20M can be used if the cable is fed
into the water heater through one of the bottom holes marked 14a.
• Mark the point 12 at which the mounting bolt is to be inserted.
Fitting the mounting bolt and attaching the pipe connecting pieces
(Fig. B)
Open up the heater (Fig. C)
Punching out the holes at the rear of the heater for the mounting
bolt and the connecting cable
Important: When mounting the appliance, only the holes actually
required should be punched out. Any other holes that are not going
to be used must be sealed watertight.
Inserting the connecting cable (Fig. D)
• Push the grommet 11 over the end of the connecting cable.
NOTICE:
Do not use the grommet for a cable with a cross-section of 16 mm2.
The appliance must then be installed flush with the wall.
WARNING:
Attention!
Without a grommet, the TR1100 18B/ 21B/ 24B is splashproof only
(IP 24).
• Place the heater over the connecting cable.
• Press the grommet into the hole in the rear wall of the heater through
which the cable should be fed. Ensure that the edges of the grommet
are flush with the hole all the way round.
• Fit the heater onto the threaded bushing 8 and secure it in place with
the nut 9.
Compensating for unevenness in the wall (Fig. E)
Water connection (Fig. 5)
• Using the locking screw 15, the water connection can be aligned by
± 10 mm vertically.
• Adapt the bend in the "hot" pipe so that it lines up with the hot-water
outlet. In doing so, make sure that the "cold" elbow connection
is not bent.
WARNING:
Attention!
Ensure that a distance of at least 6 mm is maintained to live parts
of the heater.
• Connect the water outlet and inlet and tighten the securing nut
on the mounting bolt.
Checking for leaks and flushing the heater:
• Turn on the hot-water tap.
• Check that all pipe joints are properly sealed.
