We reserve the right to make changes to dimensions and construction 14 Edition 10.07.2015

6.5.2. Boiler base

If the floor of the boiler room is moist or loose, a sufficiently high boiler base must be provided. Moisture does not

go well with electrical equipment!

Otherwise, no base is needed for the unit.

6.5.3. Boiler support

It is possible to mount the boiler on vibration dampers (available as option) to reduce noise transmission caused

by vibrations.

VG 350-450 274 mm

VG 500-600 346 mm

Dimensions and positioning of the vibration dampers

(further dimensions see chapter 4.3)

When the condensing unit has been placed correctly, the vibration dampers are put underneath it. To do this, the

unit is lifted by approx. 5 cm on one side using a hoisting device. Next, half of the vibration damper elements are

placed underneath, and the elements must lie flush with the base frame at the front. In addition, make sure that

the elements are flush with the inner side of the base frame. The unit can now be carefully lowered onto the

elements. The remaining vibration dampers are now placed underneath the opposite side of the unit in the same

way.

Afterwards, you can start installing the connection tubes on the water and flue gas side.

Attention! Once the unit is filled up, it will come down by further 2-3 mm.

6.6. Installing the unit

The unit is only allowed to be installed by authorised specialist personnel. Such personnel are familiar with the

unit and know the special aspects relating to its installation.

Each module (burner, gas line, fan, casing, boiler control panel, etc.) is supplied with its own installation

instructions. We recommend that you keep them together with these instructions. Some of these instruction

documents are also required for startup, subsequent operation and maintenance (gas compact unit, control

panel, governor, ignition electrode, O

sensor).

The boiler casing may only be assembled after the boiler has been completely connected and the heating

installation has been finished. Otherwise, there is a risk of damage.
