DESCRIPTION:

RC draught regulator (acc to DIN 4795 norm) - device that is to be mounted next to the chimney connection, equipped with a damper with an adjustable weight. The weight is to be regulated to achieve and maintain a certain underpressure ratio. After the certain weight is determined and chimney duct is too big, damper opens and lets some air into the duct - lowering underpressure to the level desired. 

Changing the negative pressure settings on the draught regulator is made by screwing the damper balance (with its knob). On this knob there is a scale to set the negative pressure value, and on the label on the damper there is a mark showing the actual value set.

Chimney draught regulator decreases too high pressure in chimney duct, which:

• appears despite correct cross-section of a chimney duct,
• appears if the cross-sectional area of chimney duct is to big; 
• is caused by temporary impact of weather conditions for example strong wind

Device is destined to be mounted: 

• on the connector which connects stove with the chimney
• over the connector
• under the connector

Maximal smoke temperature is 400oC.

USAGE:

• stabilizing and decreasing chimney draught in ventilation, flue and smoke chimney ducts
