Problem: Smoke from the fire chamber is puffing back through the draft control.
• Furnace is not connected to
return air and is drawing smoke
fumes from the flue.
• Connect to return air duct system. Or room may be too airtight, refer
to “Location and Installation” section on page 3.
Possible Causes:
Remedies:
• Excessively long run of stove
pipe from furnace to flue.
• Relocate the furnace so the horizontal run does not exceed 5 feet
and has a 2 inch rise per foot.
• The run should not contain more than 2 elbows.
• Replace with a larger flue providing a minimum of 50 square
inches but not more than 100 square inches of draft area. If the
flue is within these specifications, check the draft with a draft gage
(manometer). Your flue should provide a minimum of .04 water
column inches and a maximum of .08 water column inches.
• Too many elbows.
• Insufficient flue size.

chamber.
Possible Causes:

“CLOSED” position.
• Insufficient natural draft or an
obstruction in the flue system.
• See #6 and #9.
• Fire chamber filled to capacity
with unburned fuel.
