3.1 Matching pressure-jet oil or gas
burners for cast iron boiler units
To make engineering and installation easier, the cast iron
boilers are available as units. For the Logano GE315
series as a unit version, the Logatop VM pressure-jet gas
premix burner is available.

Fig. 21 Logatop VM gas premix burner
Fully automatic modulating gas premix burner for natural
gas E and LL, with variable speed combustion air fan,
equipped as standard with dual solenoid valve and digital
burner control unit with diagnostic display.
At the factory, the burner is fitted to the burner door,
preset and tested at operating temperature, making it
ready for immediate operation.
No additional silencing measures are required due to the
low sound emissions from the pressure-jet gas premix
burner, so it is ideal for residential buildings.

General requirements

The pressure-jet oil burners must be type-tested in
accordance with the requirements of DIN-EN 267; the
pressure-jet gas burners in accordance with DIN-EN 676.
Observe the requirements for oil and gas combustion
equipment, as well as the applicable guidelines and
regulations.
When combining a boiler with a burner, check whether
the burner manufacturer's requirements with regard to the
combustion chamber geometry are fulfilled for the
selected boiler.
3.3

Information on burner selection

The burner must reliably overcome the boiler pressure
drop on the hot gas side. With gas combustion, ensure
that the local gas network can provide the required supply
pressure for the burner.
The burner head is equipped subject to the burner
manufacturer's stipulations.
To select the optimum boiler/burner
combination, you can also contact your local
Buderus sales office.
