The chimney serves two purposes:
1. Provide “draft” to the furnace for the continuous supply of fresh air into the appliance making
proper combustion possible.
2. Exhaust smoke and combustion gases resulting from the burning biomass fuel.
Important Vent Installation Requirements
The minimum distance between the top of the furnace and a combustible ceiling surface must be 2”.
The connection from the chimney to the furnace must be made with a 6” black pipe.
The minimum distance between the connection pipe and a combustible wall surface must be 18”.
Do not use more than two elbows in the connection between the furnace and the chimney.
Horizontal elements of the connection pipe should have a minimum rise of ¼” per foot of run to allow
condensation to flow back into the furnace.
Listed Chimney
Use a listed type HT pre-fab. Material of the chimney connector should be made with a minimum 24
gauge black or blued steel. A listed chimney must be rated for solid fuel burning appliance, comply
with NFPA Standard 211, and all applicable building codes. Consult a qualified furnace installer and/or
the local building inspector to be sure the chimney and connections comply.
Masonry Chimney
Use a low heat masonry chimney. Material of the chimney connector should be made with a minimum
24 gauge black or blued steel. An existing lined masonry chimney must be clean and inspected. All
connections to the chimney must comply with NFPA Standard 211 and all applicable building codes.
Consult a local building inspector and/or a qualified furnace installer to be sure the chimney and
connections are safe and compliant.
Formation of Creosote and the Need for Removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-
burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote
makes an extremely hot fire. The chimney connector and chimney should be inspected at least twice
monthly during the heating season to determine if a creosote buildup has occurred.
Check daily for creosote buildup until experience shows how often cleaning is necessary.
Be aware that the hotter the fire, the less creosote is deposited, and that weekly cleaning may be
necessary in mild weather, even though monthly cleaning may be enough in the coldest months. A
small intense fire is preferable to a large smoldering fire to reduce the amount of creosote deposition.
If creosote has accumulated it should be removed to reduce the risk of a chimney fire.
Have a clearly understood plan to handle a chimney fire.
