Fig. 4.1 Distances during installation (dimensions in mm)
The combination of units must be installed on a flat
vertical wall which is large enough for the shift load
storage tank with mounted combi boiler, including the
required minimum clearances and space allowances for
installation. The required minimum clearances during
installation can be taken from Fig. 4.1.
The minimum clearances and installation clearances are
shown on the installation template. They are:
– 5 mm on each side of the unit combination
– 180 mm underneath the unit combination
– 165 mm above the boiler if using a flue pipe of 100 mm
outside diameter
– 246 mm above the boiler if using a flue pipe of 125 mm
outside diameter
– 500 mm in front of the unit combination to permit
easy access for service work.
Please note that, under the unit combination, there
should be adequate space to position the drain pipes via
a drain funnel. The drain must be visible!
Note!

If the boiler is to be installed in a timber framed
building, it sohuld be fitted in accordance with
IGE/UP/7/1998 „Guide for gas installations in
timber framed dwellings".
