The overheat discharge valve incorporated in the heating system will
open the cold water feed at a flow temperature of approx. 95°C
.
* The values shown represent the mean over a combustion period. These values apply
under test conditions at nominal heat output, burning approx. 2.9 kg dry beech wood
per
hour
.
** Higher draughts should be reduced to less than 30 Pa by appropriate measures, such as a
secondary air device or air regulator.
