Open combustion unit

Zone contains open combustion unit

 EPG
This box indicates if the zone contains an open combustion unit. Extra ventilation air is surcharged for such an open combustion unit. Examples of open combustions units are geysers, boilers, gas stoves, or fireplaces which extract air for combustion from the heated calculation zones. Only one combustion unit can be specified per zone.

Type of combustion

 EPG
The type of combustion unit within the heated calculation zone is indicated here. The specific air volume flow required for this combustion unit, and a correction factor for operation time are determined depending on the type of combustion unit.

•      Fireplace

•      Gas stove

•      Oil stove

•      Coal stove

•      Stove, solid fuel other than coal

Nominal load

 EPG
The nominal load of the combustion unit determines the air volume flow required for the combustion unit. The minimum values for nominal load are applied in case the power is not specified or the specified power is too low.
