Max.spread
A heat exchanger protective functionisintegratedintotheCGB-75/100. This prevents
stressesinthematerialbylimitingthemaximumtemperaturedifferentialbetweenow
and return. The output is restricted at 28 K and above. If 38 K is nevertheless reached, the
burnershutsdownbrieywithoutafaultmessage.Thischaracteristicmustbetakeninto
account when selecting the components (e.g. pumps, heat exchangers and cylinders).

rounded by combustion air and meet higher requirements
for gas tightness.
2)
For type B23, B33 the combustion air is drawn from the
installationroom(openuegascombustionequipment).
3)
In Switzerland, observe the G1 gas guidelines!
For type C, combustion air is drawn through a sealed system
from the outside (room sealed combustion equipment).
