Condor DraftMaster SF Series

Fireplace Anti Downdraft Cowls

Condor DraftMaster SF Series

(solid fuel)

anti downdraft cowl for wood and gas heaters

making your fireplace perform better

Developed for masonry chimneys and steel flue configurations

for

slow combustion stoves

and open fireplaces

Features

  • eliminates downdraft
  • improves updraft
  • improves heat output and fuel efficiency
  • introduces appropriate back pressure
  • minimizes excessive heat loss
  • eliminates carbon build up
  • non contamination in water harvesting

Since 1983 Condor has a 100% success rate in solving wood heater problems arising from inclement weather conditions and incorrect installations.

The Condor DraftMaster SF (cowl), a motionless multi venturi unit, not requiring directional accommodation, was developed to arrest downdraft potential in wood heaters and fireplaces.

The Condor DraftMaster SF consists of conical sections suspended in series so as to form a multi-venturi configuration, with it’s revolutionary split cap, which is performance enhanced when using the natural air currents (wind), arising from pressure differentials.

The Condor DraftMaster SF multi venturi terminal (cowl) is undoubtedly the most efficient solid fuel discharge terminal in the world today.

The DraftMaster SF unit is available with a custom transition to suit existing installation and configurations.

Dimensions for anti downdraft cowl

The SF Condor Terminal was initially designed to arrest downdraft in fireplaces and slow combustion stoves. Ongoing development has now produced a unit that improves the general performance as follows,

  • better up draft
  • downdraft potential is redirected
  • carbon buildup is minimised
  • roof staining by resin drip is eliminated
  • non contamination when water harvesting.
  • smoke shelf in fireplace is non essential.
  • establishing appropriate back pressure
  • elevation of stack height to 900mm above roofline. ('A' frame structures excepted)

The SF Condor Draftmaster Terminal (Cowl) has excellent discharge characteristics and the adherence of carbon and resinous materials does not occur as with conventional flue caps and cowls.

The Condor DraftMaster SF terminal (cowl) is manufactured in Stainless Steel and Polyester resin coated.

 

The Condor DraftMaster SF terminal (cowl) is also of exceptional benefit to slow combustion stoves with their small diameter flues. The slow burning cycle promotes the likelihood of carbon and resin deposits in the flue section.

Important Note:

The Condor DraftMaster SF terminal (cowl) will not resurrect a bad installation or a poorly designed fireplace.

Maximum discharge size of steel flue is determined by outer casing size encapsulating inner active.
Venting between casing and active at top end is not recommended.

Discharge Size of Chimney is determined by the measurement of the diagonal corners of the opening at the top.

Correct choice ensures optimum performance.
