Draft Control - Napoleon HYBRID 150 Instructions D'installation Et D'opération

• Closing the doors too quickly after refuelling will reduce the fi rebox temperature and may result in
an unsatisfactory burn.
• As soon as the doors are closed, you may (if glass door is installed) observe a change in the fl ame pattern.
The fl ames will get smaller and lazier because less oxygen is getting into the combustion chamber. The
fl ames, however, are more effi cient. The fl ames will remain lazy but become larger again as soon as the
fi rebricks have been heated thoroughly and the chimney becomes heated and provides a good draft.
• With the doors opened the fi re is wastefully drawing heated room air up the chimney, certainly not
desirable. Always operate with the doors fully closed once the medium sized logs have caught fi re.
• You can now add larger pieces of wood and operate the appliance normally. Once the appliance is
entirely hot, it will burn very effi ciently with little smoke from the chimney. There will be a bed of hot
coals in the fi rebox so you can safely fi ll the fi rebox with wood to the bottom of the secondary air tubes.
Can't get the appliance operating? Use more kindling and paper.
Assuming the chimney and vent are sized correctly and there is suffi cient combustion air, the lack of suffi ciently
dry quantities of small kindling is the problem. Thumb size is a good gauge for small kindling diameter.
Can't get heat out of the appliance? One of two things may have happened. The appliance door may have
been closed prematurely and the appliance itself has not reached optimum temperature.
Re-open the door and/or draft control to re-establish a brisk fi re. The other problem may have been wet wood.
The typical symptom is sizzling wood and moisture being driven from the wood.

DRAFT CONTROL

ALWAYS OPERATE THIS APPLIANCE WITH THE FIRE BOX DOOR CLOSED AND LATCHED EXCEPT
Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local geography, nearby obstructions and other forces.
Adjusting the draft control regulates the temperature. The draft can be adjusted via the thermostat from a low
burn rate with the air control on the low setting to a fast burn rate with the air control on the high setting.
Inadequate draft may cause back-puffi ng into the room and may cause plugging of the chimney. Too much
draft may cause an excessive temperature in the appliance, glowing red appliance parts or an uncontrollable
burn which can all lead to a chimney fi re or a permanent damage to the appliance.
Roll up some newspaper, light it and place it near the appliance fl ue until the chimney begins to draw. When a
fi re is burning, open the door slowly to avoid drawing smoke into the room.
A properly installed Napoleon appliance should not smoke.
If yours does, check the following: Has the chimney had time to
get hot? Are the air intake hoods blocked closed? Is the smoke
passage blocked anywhere in the appliance or chimney? Is the
smoke fl ow impeded by too long a horizontal pipe or too many
bends? Is it a weak draft perhaps caused by a leaky chimney,
a cold outside chimney, too short a chimney, or a chimney too
close to trees or a higher roof?
DURING START-UP AND RE-FUELING.
NOTE
Differences in the chimney height
and draft may lower overall burn
times.
