CHIMNEY DRAFT
NOTE: A DRAFT READING OF 0.05[12.45] to 0.06[14.94] (Water Column[Pascals]) IS REQUIRED FOR PROPER
BURNING OF THIS APPLIANCE.
Draft is a function of the chimney, NOT THE APPLIANCE — Do not expect the appliance to draw. Smoke spillage
into the house or excess buildup of condensation or creosote in the chimney are warnings that the chimney is
NOT functioning properly. Correct the problem before using the appliance. Following are some possible causes
for improper draft.
1. The connector pipe may be pushed into the chimney too far, stopping the draft.
2. If the chimney is operating too cool, water will condense in the chimney and run back into the appliance.
Creosote formation will be rapid and may block the chimney. Operate the appliance at a fire level high
enough to keep the chimney warm preventing this condensation.
3.
If the fire burns well but sometimes creates excessive smoke or burns slowly, it may be caused by the chimney
top being lower than another part of the house or a nearby tree. The wind blowing over a house or tree falls on
top of the chimney like water over a dam, beating down the smoke. The top of the chimney should be at least
three (3) feet above the roof and be at least two (2) feet higher than any point of the roof within ten (10) feet.
