be removed during installation and replaced by suitable, permanent-
ly tight plugs
. The connections are clearly marked and must not be used
for any other purpose. The integral safety device (safety heat exchanger)
must not be used to heat water. We recommend the use of straight or
angled radiator screw connections for the pipe connections.

2.4. Minimum crosssections for convection air
The minimum cross-sections for the convection air (supply air and
circulating air) in the lining or heat chamber must be executed as follows.

Generally speaking, the Technical Rules of the Tiled Oven and Air
Heating Building Trade (TR-OL 2006) must be followed.
2.5. Bleeding
Two bleed valves are available for bleeding the water heat exchanger. For
the Varia 1V/1Vh H
2
O, only one bleed valve is provided, on the upper heat
exchanger, and on the Varia Ah H
2
O and Varia A-FDh H
2
O the bleed
valve is located at the top left and right. Firstly, the upper bleed valve (in
the area of the flue gas collector) can be used. This requires that a
sufficiently large opening be provided in the lining in the immediate
vicinity. Secondly, the lower bleed valve (in the area of the connections on
the rear) can be accessed through the inspection opening in the combus-
tion chamber and this can be used. After commissioning, the insert must
be bled several times because the heating water emits gases due to the
high temperatures.
For the
Varia 1V H
2
O
, a vent pipe fitted to the rear wall is available (see
Fig. 3).
