Note 1: 6” (152mm) diameter single wall, minimum 24 MSG black or blued steel connector pipe with a listed factory-built type HT
chimney suitable for use with solid fuels or a masonry chimney.
Note 2: 6” (152mm) diameter double wall insulated connector pipe with listed factory-built type HT chimney or a masonry chimney.
(Mobile home venting system must be equipped with a rain cap and spark arrestor.) For installations with a preexisting class A
chimney system, a listed stainless steel chimney liner should be installed, or the existing chimney examined by a chimney sweep for
acceptable further use.
Note 3: Alcove specifications: Maximum depth of alcove shall be no more than 48” (1219mm). For additional alcove information
and clearances, refer to clearances to combustibles above.
NOTE: Unit is approved for use with listed double wall air-insulated chimney connector or elbows.
When locating your stove consider safety, convenience, traffic flow, and the fact that the stove will need a chimney and chimney
connector.
FLOOR PROTECTION: Floor protector must be noncombustible material, extending beneath heater and to the front/sides/rear as
indicated.
NOTE: A 3/8” (10mm) minimum thickness tile or equivalent is recommended, but not required.
NFPA 211: Use a noncombustible material with 1” (25mm) ventilated air space to reduce clearances. However, this is not to exceed
50% of Quadra-Fire’s specified clearances.
NOTE: Must follow NFPA 211 spacing and materials to qualify. It is also subject to local jurisdiction.
AVOID FIRE: Maintain the designated clearances to combustibles. Insulation must not touch the chimney. You must maintain the
designated air space clearance around the chimney. This space around a chimney is necessary to allow natural heat removal from the
area. Insulation in this space will cause a heat buildup, which may ignite wood framing.
