FLUE DRAUGHT

 

 

The chimney can be checked, before the stove is installed, with a smoke pellet. If the 
chimney doesn't pull the smoke it may suggest the chimney needs attention (see the 
Flue Diagnosis Table, below). 
 

 

This test is only a guide as an apparently poor flue may improve once the 
stove is installed, lit and the flue is warmed. If, once the stove is installed, 
if there is any doubt that the chimney is providing an adequate draught; 
a flue draught reading can be taken with the stove lit. Two flue draught 
readings should be taken, one with the stove at minimum rate and one at 
maximum rate. 

 
MEASUREMENTS 
The flue draught test hole is located on the right hand side of the stove at the back near 
the top see fig. 4.  Remove the screw to allow reading to be taken, replace the screw 
once readings are complete. 
 
MINIMUM 
The stove should be lit and allowed to warm the flue thoroughly. The air controls can 
then be set so that the stove burns on a low setting. Allow the burning rate to become 
steady.  The flue draught reading should now be taken with the primary air intake closed 
and the airwash control fully open. 

 

MAXIMUM 
The primary air intake can now be opened to allow the stove to burn at maximum rate. 
Give the stove some time for the burning rate to become steady and then close the 
primary air intake, make sure the airwash control is fully open and take a flue draught 
reading immediately.  Ideally, the flue draught reading should range between 1mm wg 
(10 Pa) and 2.5mm wg (25 Pa).  Any readings significantly outside this range may 
indicate the need for remedial action. 
 

Low flue draught symptoms:

 

difficult to light and smoke coming into the room.

 

CAUSE 

REMEDY 

Cold chimney 

Line the chimney 

Chimney too short 

Extend the chimney 

Down draught 

Relocate/extend chimney terminal.  Fit an anti-down draught 
cowl 

Chimney diameter too large 

Line the chimney 

Chimney obstruction 

Clear/sweep the chimney 

Restricted air supply 

Check for competing draughts (other chimneys, extractor 
hoods/fans).  Fit an air vent if the room is sealed. 

High flue draught symptoms:

 

fire difficult to control, fuel will not last, stove too hot, stove damage, chimney fire.

 

CAUSE 

REMEDY 

External wind conditions combined with 
chimney terminal 

Fit stabiliser cowl. 
Fit flue draught stabiliser.
