2. Installation
2.1 Setting up, levelling
No special foundation plate is required for erecting the
boiler (sufficient supporting capacity for the boiler must
be guaranteed) ­ for operating weight, see chapter 3.
If there are boiler rooms in the domestic domain, vibration
dampers are to be mounted under the boiler plinth rails.
The distance from the wall behind the boiler
must always be sufficient in order to gain ac-
cess to the cleaning opening in the flue gas
col lec tor. It must be possible to swing open
the boiler door with the burner.
Levelling
Align the top edge of the boiler water jacket (boiler lon gi­
tu dinal axis) exactly horizontal.
2.2 Syphon assembly information
When combusting hydrogenous fuels which cool down
below their dew points, the water vapour in the flue gas
condenses. This condensate must be diverted out of the
calorific value heat exchanger or the flue gas system.
The amount of the resulting condensate depends on the
water entry temperature in the heat exchanger, the excess
air in the flue gas and the load of the heat generator.
The following standard values can be assumed for the
resulting amount of condensation (at theoretical 100 %
condensation and consideration of an average humidity):
Natural gas: approx. 0.8 l/m
3
gas
Oil-firing: approx. 0.9 l/litre oil
The flue gas condensate must be introduced into the
public sewer network as prescribed. Neutralisation
equipment might be needed ­ please contact the nearest
Hoval branch.
In particular with oil-firing, the use and suitability of the
neutralisation equipment must be taken into account.
A syphon must be installed directly at the discharge of the
calorific value heat exchanger; it (including the connecting
piping between the heat exchanger and syphon) is to
be designed to be resistant to flue gas temperatures
up to 240 °C and must be filled with water before the
system is commissioned. The height of the syphon must
correspond at least with the flue gas counterpressure
of the heat exchanger (up to about 4 mbar) ­ start­up
pres sure shocks of the burner or possible additional
counterpressure of the flue gas line must also be taken
into account.
The connection cables of the drainage piping must be
made of corrosion­resistant materials such as PVC or
stain less steel.
After a long system standstill, the water level of the syphon
must be checked and refilled with water if necessary.
