Vitocrossal 300, CT3 Series Installation
Please observe the minimum clearances starting on page 8.
The boiler itself is mounted on a boiler pad.
This boiler pad should be placed on a concrete or
equivalent foundation. A recommended foundation size
for each boiler model can be found on page 29. The
minimum height should not be less than 4 in. (100 mm).
1. Remove wooden shipping blocks from boiler base.
2. Remove the 4 leveling bolts from boiler skid and
insert in the boiler skid. It is recommended to place
a flat piece of steel plate under each floor leveling
bolt for better weight distribution and adjustment,
and to compensate for an uneven floor.
3. By adjusting the floor leveling bolts and, if necessary,
adding a heavier steel plate, most of an uneven floor
can be properly corrected.
