Smoke Troubleshooting Checklist
For Outdoor Furnaces
I. Installation Issues (Improper Smoke Dispersal)
A.
Chimney height relative to nearest downwind neighbor
1.
If located 50 feet or less to any residence not served by the furnace, it is
recommended that the stack be at least 2 feet higher than the eave line of
that residence.
2. If located more than 50 feet but no more than 100 feet to any residence, it
is recommended that the stack be at least 75% of the height of the eave
line of that residence, plus an additional 2 feet.
3. If located more than 100 feet but no more than 150 feet to any residence, it
is recommended that the stack be at least 50% of the eave line of that
residence, plus an additional 2 feet.
4. If located more than 150 feet but no more than 200 feet to any residence, it
is recommended that the stack be at least 25% of the height of the eave
line of that residence, plus an additional 2 feet.
B. Furnace located in sheltered area; insufficient wind to disperse smoke.
C. Furnace sizing. Similar to other heating appliances, furnace should be
properly sized based on the estimated heat loss of the served structure.
II. Fueling Issues
A.
Burning less than optimal wood
1. Moisture content: Optimal moisture content should be between 20%
and 30% (seasoned wood)
2. Species: Hardwoods generally tend to burn cleaner than softwoods
3. Size: Larger pieces of wood tend to burn cleaner than smaller pieces
B. Burning less than optimal fuel loads
1. Loading: Firebox should be loaded based on outdoor temperature,
anticipated heat load requirements and the manufacturer’s instructions.
Do not overload the chamber.
2. Charging intervals: Firebox should be charged regularly at the intervals
specified by the manufacturer’s instructions. Optimally, the firebox will
be charged “hot,” i.e., the fire will not go out between chargings.
C. Burning improper fuels
1. Only burn fuels approved by the manufacturer
2. Do not use volatile starters (such as lighter fuels, gasoline, chemicals)
unless approved by the manufacturer
3. Do not burn the following:
a. Trash or household garbage
b. Plastics
