VENT SYSTEMS
A Harvester must be vented into a non defective, clean, and properly lined masonry chimney or must be
installed using any one of a number of different manufacturer’s factory-built vent pipe product.
If a masonry chimney system is used, it must conform to all local building codes and must be properly lined
with an approved pellet (all fuel) stainless steel liner.
FACTORY-BUILT CHIMNEY
The Harvester can utilize factory-built vent systems from a number of different manufacturers either in
3” or 4” diameter depending on installed lengths. All Harvester vent systems must be Type L or Type
PL rated vent and tested as well as listed to UL Standard 641.
Freestanding clearances are listed in TABLE 2 and must be maintained. If local code allows, these
distances can be reduced when acceptable shielding is provided. Consult a local code authority and
certified installer to ensure that a specific installation meets proper code. The following
recommendations should be adhered to:
a) Do not install damaged parts and do not mix and match manufacturer’s parts.
b) If a vent system must pass through ceilings or walls, make sure all combustible materials and
building installation products are a minimum of 3” away from the vent pipe.
c) When vent systems exit through walls, make sure NFPA rules are followed for distances from
windows and openings.
d) Ensure good workmanship is maintained during vent system installation.
e) Never use a vent system with an inside diameter that is smaller than the Harvester flue outlet.
f) When vent systems pass through a ceiling, use a Firestop/Support assembly.
g) Use 1/4” sheet metal screws to secure locking vent system joints along with RTV and tape.
h) Never penetrate the inner lining of a vent system with any screws.
i) Never install single-wall pipe to a Harvester.
j) Single wall pipe can only be used as a liner in a masonry fireplace.
k) DO NOT connect B-vent pipe with aluminum liners to vent a Harvester.
l) The use of pellet or corn fuel does not eliminate the need for regular inspections and cleaning.
m) Always follow the vent system manufacturer’s installation instructions.
MASONRY BUILT CHIMNEY
Before connecting this Harvester to a specific chimney, be sure to have the chimney inspected by a
chimney professional and cleaned, if necessary. Once cleaned, assuming the masonry chimney is of
larger diameter than required by the Harvester, a full stainless steel liner will need to be installed. This
liner will need to be free from cracks, deterioration, softening, or other damage that may prevent it from
containing the byproducts of combustion.
CAUTION: When installation requires connection from a Harvester flue through a combustible wall
to a masonry chimney a UL Listed wall thimble (wall penetration system) must be utilized. Always
conform to local codes, utilize a professional installer, and ensure a proper vent system be utilized with
a Harvester installation. Country Flame recommends the use of smoke and carbon monoxide detectors
when installing a Harvester.
