Measuring And Adjusting The Draft - Drolet YUKON Instructions Manual

MEASURING AND ADJUSTING THE DRAFT

• Your stove operates with a natural draft, created by the ascension of combustion gases in the chimney.
This movement creates a suction effect in the stove and forces ambient air to pass through the perforations
in the burner. That air is needed for combustion.
• To make sure the stove will function properly, it is essential that a draft reading be taken. The draft is
measured in inches of water column using a manometer. Your qualified technician should have this tool.
• The minimum draft requirement is 0,05 INWC. This is indicated on page one of the manual. The draft has
to be attained when the oil flow control knob is set at position #1.
• The draft can be taken using the hole located on the stove's cooking surface, or using the opening on the
draft regulator (usually plugged by a rubber cap). The hole on the cooking surface is the best area.
IMPORTANT : ALWAYS MEASURE THE DRAFT WITH ALL AIR-MOVING EQUIPMENT OPERATING
(RANGE HOOD, BATHROOM FAN, AIR EXCHANGER, DRYER, ETC.)
ref. : standard CAN/CSA B-139 art. 4.1.5.
DRAFT REGULATOR
• An excessive draft is just as bad as one that is
too low.
• The regulator at the back of the stove controls
the draft if it becomes excessive.
• If the draft exceeds 0.08 INWC, the draft
regulator needs to be adjusted.
To adjust the draft regulator, you have to screw or
unscrew the counterweight located on the regulator.
If the regulator is open, it lowers the draft. If it is
closed, it increases it.
THE ONLY RIGHT WAY OF MEASURING THE DRAFT IS BY USING A MANOMETER THAT GIVES A
READING IN INCHES OF WATER COLUMN. ANY OTHER METHOD (CANDLE, MATCHES, ETC.) ARE
UNRELIABLE.
INSTALLATION OF YOUR STOVE SHALL BE IN ACCORDANCE WITH THE CAN/CSA B-139
(INSTALLATION CODE FOR OIL-BURNING EQUIPMENT) IN CANADA AND THE NFPA 31 STANDARD
(NATIONAL FIRE PROTECTION ASSOCIATION STANDARD FOR OIL-BURNING EQUIPMENT) IN THE
UNITED STATES.
THE INSTALLATION SHOULD BE PERFORMED BY A QUALIFIED TECHNICIAN, MEMBER OF A
RECOGNIZED ASSOCIATION IN YOUR AREA.
