4- The carburetor's filter is clogged, which reduces the oil flow.
Solution : Clean the carburetor's filter. Start by closing all taps. Remove the two screws on the small
silver plate on the side of the carburetor. Then, remove the rubber joint and the nylon filter. Clean the filter
with hot water. Put everything back into place.
5- The chimney draft is too weak or too strong.
Solution #1: In the case of a chimney draft that is too weak, the problem may simply be caused by a lack
of heat inside the chimney as a result of an inadequate lighting procedure. Start the fire by pouring 2 onces
(50ml) of fire-lighting gel into the burner. Do not turn the oil on right away (leave the oil flow control knob at
zero). The burning gel will allow the chimney to heat up until it reaches a temperature that will generate an
adequate draft. When the burning gel's intensity starts to diminish, turn the oil flow control knob to position
#1. Increase the oil flow by one position every 10 minutes until you reach the desired intensity.
Solution #2 : A draft that is too strong or too weak may be the result of an improper adjustment of the
draft regulator located at the back of the stove. The draft regulator should have been adjusted by a
qualified technician when the stove was installed. If this has not been done, have a qualified technician
take a draft reading and adjust the draft regulator. Your qualified technician must use a manometer to
obtain a draft reading. During this procedure, the oil flow control knob must be set at position #1 and all air-
moving equipment inside the house (range hood, heat exchanger, bathroom fan, etc.) must be in operation.
The reading on the manometer must correspond to the minimum prescribed draft indicated on the
certification plate located at the back of the stove. The prescribed draft is set at 0,05 INWC for most oil
stoves.
Solution #3 : If the chimney draft remains too weak, Your stove may be located in an area where the
volume of oxygen is not sufficient to allow for a complete combustion. If there is a window in the room
where the stove is located, open it by at least 2 inches. If this solves the problem, it may indicate that your
house is over-insulated or the room is too small. Without an additional supply of oxygen, your stove will not
function normally. The ideal solution is to install a permanent fresh air intake located at a distance of 6 to
12 inches from the stove.
Solution #4 : Your exhaust system may be toot short. In order to obtain a sufficient draft, your exhaust
system must have a minimum height. A minimum height of 15 feet (from the connector at the back of the
stove to the chimney cap outside the house) will be adequate in most cases. HOWEVER: remember that
longer is not always better. An exhaust system that is excessively high may be difficult to pre-heat and
control. If your exhaust system is too short, add some chimney sections.
Solution #5: Your exhaust system may be too tortuous or may not have the minimum slope required to
allow for a proper draft. Your exhaust system should never have more than two 90
the horizontal sections of your exhaust system should be as short as possible (maximum 8') and must have
a minimum upward slope of ¼" per foot.
Solution #6: Your chimney may be oversized. The effect of an oversized chimney is generally the
reduction of the temperatures inside the chimney, due to the larger volume that needs to be heated. This
weakens the chimney draft. Our oil stoves are tested to be installed on a chimney with an interior diameter
of 5 inches (127mm). If you do not have a 5" chimney, you can insert a stainless steel liner inside the
existing chimney in order to reduce its interior diameter to 5 inches.
temperatures higher, therefore increasing the chimney draft.
Solution #7: In the case of excessive draft, it is possible to install a second draft regulator located within
the first 18 inches on the stove connector. Your dealer will be able to supply the appropriate part.
