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 air-wash control is fully open and take a flue draught reading immediately.
Ideally, the flue draught readings should range between 1mm wg and 2.5wg .Any readings
significantly outside this range may indicate the need for remedial action.
Note:
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, 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 firing rate and one at maximum
firing rate.
Flue Stabilizer
A flue stabilizer can be fitted to reduce the draught through the stove if the flue draught is too high.
The flue stabilizer should be:
•
fitted in the same room as the stove
•
The same size as the flue pipe
•
fitted no closer than 700mm to the flue outlet of the appliance.
