Information regarding the connection sets
The dimensioned drawing shows example fittings for upward connec-
tion and connection to the left/right, for installation on finished walls.
For the dimensions of the individual connection sets, see the technical
guide.
If using connection sets (for downward connection) with a preinstalla-
tion bracket for installation on finished walls, maintain a wall clearance
of
≥
70 mm.
The adjustable feet give all height measurements a tolerance of
+15 mm.
Side clearance for service work
For burner service, use the cleaning set available as an accessory.
The burner holder supplied as part of this set enables an optimum
service position to be achieved for the burner. In addition, a side clear-
ance of 300 mm (on the left or right) next to the Vitoladens 333-F is
recommended.
Variable speed heating circuit pump in the Vitoladens 333-F
The integral circulation pump is a high efficiency DC pump (corre-
sponding to energy label A) with more than 50% less power consump-
tion than conventional pumps.
The pump speed and consequently the pump rate is regulated subject
to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default speed via
an internal data BUS to the circulation pump.
Individually match the minimum and maximum speed plus the speed
for reduced mode to the existing heating system using the control unit
codes.
The minimum pump rate is selected in coding address "E7". The max-
imum pump rate is selected in coding address "E6". The setting ranges
of these codes are limited by boiler-specific parameters.
