Table 1 - Clearances
* Reduced clearances may be available for A, B, C and D dimensions per
NFPA 211 - latest edition, Standard for Chimneys, Fireplaces, Vents and
Solid Fuel-Burning Appliances (in Canada CSA B365 - latest edition). See
section on “Reduction of Appliance Clearance with Specified Forms of
Protection.”
(1) (USA) 16” minimum hearth extension on all stoves and inserts as measured
from the door opening of the unit. (Canada) 18”(450 mm) minimum hearth
extension on all stoves and inserts as measured from the door opening of
the unit. Minimum distance of floor protection to the side = 8” (200 mm).
This is measured from the sides of the door opening in the USA and from
the sides of the insert in Canada.
(2) J = Maximum lintel depth without flue offset or smoke deflector.
(3) If the mantel projection is 8” or less, the ‘A’ mantel clearance may be
reduced to 14”.
NOTES:
• Facing material that projects more than 3/4” (19 mm) from the wall
is considered a mantel or side wall.
