1. Check the chimney draft. With a good fire burning, the
chimney should supply .06 " updraft.
2. Check draft controls for proper operation.
3. Check the chimney and be sure it is clean.
4. Chimney may be too low. Increase the height. Make sure
the chimney is structurally sound.
5. Add more air to the room. Your home may be so airtight
that not enough oxygen is reaching the fire.

7. Check the insert wings to be certain that there is an air
tight seal between the wings and the fireplace front.
8. Check the ashes. Ash pan and ash compartment may be
overloaded with ashes.
9. Check your chimney for down drafts. This is caused by
air currents being deflected down the chimney from higher
objects, such as trees, buildings and hills. This problem
can usually be corrected with an open-vented chimney
cap.
10. Make sure the chimney clean-out door is tightly closed
and sealed.
11. If other fuel burning devices are connected to the chimney,
they may be causing draft problems. This must be
corrected by your heating contractor.
3.4 ChImNEY dETAIlS
Chimney Liners - Most of the customer inquiries received
are problems caused by poor, or in some cases, excessive
draft. A result of poor draft could be creosote, back-puffing,
and smoky firebox when loading. Indications of excessive
draft are burning too much fuel and high stack temperatures.
The most common cause of poor draft is an improperly sized
flue liner. We recommend that the chimney liner's inside
dimensions be at least as large as the appliance's collar size.

G. Elbow Restrictions - The flue pipe is connected to the
chimney with too many elbows, reducing the draft the
chimney can provide.
H. Multiple Venting - No more than one device shall vent into
the same chimney flue.
