The DM2000 is only used for measuring flue draught. As chimney draught is a negative pressure it has to be measured on the negative connection of the DM2000 to get a positive result (e.g 20 PA draught – under pressure). The instructions for use are printed on the reverse side of the unit.

In operation when the unit is turned on, there is a rubber hose connected to the negative probe on the unit. A stainless steel probe is connected to the rubber hose. The stainless steel probe is inserted into the appliance where the flue draught is to be measured in a pre-warmed flue. The readings should be recorded during a commissioning process and comply with manufacturers requirements for draught. Further invstigation will be required where excessive or inadequate draught is measured.
