ADJUSTING THE DRAUGHT
• Your stove operated with natural draught, created by the ascension of combustion gases in the
chimney. This movement creates a siphon effect in the stove and forces ambient air to go in the
burner by the holes in its surround. These orifices let air in for combustion.
• For the unit to function properly, it is essential to check the quality of the draught using a draught
gauge. The draught is usually measured in inches of water column.
• Check the minimum draught required of the unit on page 1. The draught required of the unit on
page 1. The draught mentioned has to be reached rapidly at a minimum settling (position #1).
• Depending on the model, the draught can be taken by the orifice on the cooking surface. The
measure can also be taken by the orifice on the draught regulator usually plugged by a rubber cap.
The orifice on the cooking surface is still the best area.
IMPORTANT : ALWAYS MEASURE THE DRAUGHT WITH ALL VENTILATION EQUIPMENT
INSTALLED IN THE HOUSE (RANGE HOOD, BATHROOM FAN, AIR EXCHANGER, DRYER, ETC
IN OPERATION.) ref. : standard CAN/CSA B-139 art. 4.1.5.
DRAUGHT REGULATOR
• An excessive draught is as bad as a draught
to low.
• The regulator controls the draught when it is
excessive (in high winds for exemple).
• If the draught exceeds 0.08 in of water
column, you will have to adjust the regulator.
• To adjust the draught you have to screw or
unscrew the counterweight on the regulator.
Regulator open lowers the draught regulator
closed increases the draught.

THE ONLY RIGHT WAY OF MEASURING THE DRAUGHT IS TO USE A DRAUGHT GAUGE THAT
GIVES A READING IN INCHES OF WATER COLUMN. ALL OTHER METHOD (CANDLE,
MATCHES, ETC.) ARE UNRELIABLE.
INSTALLATION OF YOUR STOVE HAS TO BE IN ACCORDANCE WITH CAN/CSA B-139
INSTALLATION CODE FOR OIL-BURNING EQUIPMENT IN CANADA AND STANDARD NFPA 31
NATIONAL FIRE PROTECTION ASSOCIATION STANDARD FOR OIL-BURNING EQUIPMENT IN
THE U.S..
THE INSTALLATION SHALL BE MADE BY A QUALIFIED PERSON MEMBER OF THE
CORPORATION IN FORCE IN YOUR AREA.
