Solution#2 : The lack of adequate draft may be due to 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. If the adjustment of
the draft regulator does not increase the chimney draft, go to solutions #3 to #6.
Solution #3: 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.
Solutions #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.
WHY IS THERE ODORS OR OCCASIONAL SMOKING PROBLEMS?
Possible causes and solutions :
1- The room where the stove is located is under a negative pressure effect.
Solution #1: If this situation occurs when you light-up the stove, it is probably due to the fact that the
chimney is very cold. Start your stove by pouring approximately 2 onzes (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: Check if this situation occurs when air-moving devices are working (range hood, heat
exchanger, bathroom fan, etc.). If so, make sure you turn those systems off when you operate the stove. If
this is not possible, you will need to install a permanent fresh air intake near to stove in order to replace the
air that is sucked out of the house by your ventilation systems. The fresh air intake should be install at a
distance of 6 to 12 inches from the stove.
