4.2.14 Installing the Emissions Connection to Central Roof Heating
Measure the point where the emission
pipe opening will be based on the posi-
tion of the unit. Install the special feed
through socket as appropriate for the
space provided. Lead the emission pipe
through the socket and connect it to the
unit. Use the sleeves specially designed
for the opening of the roofing paper in or-
der to insure it is airtight. The emission
line must be level.

Roof Heating
Follow the installation instructions for the respective emissions system!
4.2.15 Connecting the Condensed Water Drain
Lay plastic piping (min. Ø 32 mm or larger that leads to the drain) app. 2 cm under
the condensed water drain connection. Do not place a permanent connection on the
siphon in the boiler as this hinders maintenance.
•
Fill the boiler siphon to avoid flue gases from escaping into the room.
•
The condensed water drain must not be sealed.
•
The emission pipe should have a minimum slope of 3 cm per meter
and a maximum horizontal length of 5 meters.
•
Disposing of condensed water via rain gutters is not permitted.
•
Condensed water lines must be installed according to regulation.
4.2.16 Neutralisation
ATV Bulletin M 251 regulations and state provisions apply! A pH balancing system
can be installed retroactively for the Bruns wall boiler. A neutralization system is re-
quired for boiler capacities exceeding 25 kW. Regional regulations for running con-
densed water into the canalisation system are a deciding factor. Neutralisation gran-
ulates must be checked yearly by the operator and if necessary, renewed.
