**) Minimum recommended stand-by output during intermittent operation during which the fire can be
maintained. In order to maintain the fire outside of the heating season there must always, as a minimum,
be a hot water tank as well as 1-2 radiators connected (open)..
***) These are the minimum smoke temperatures which are achieved by means of the approval with the
above mentioned 24-hour operation at minimum output. This smoke temperature is too low for ordinary
operation, with ordinary chimneys. We consider a smoke temperature of 100°C as being the absolute
minimum for ordinary chimneys. We have therefore built-in an alarm on the smoke temperature at 100°C.
This means that if the smoke temperature has been below 100°C for half an hour the boiler will stop. This
alarm function also ensures against continuing to feed fuel into the boiler, if the fire has gone out
