APPROVED CATEGORY III Venting Method
In North America (Canada and the USA) the SPECIAL VENTING method, as detail below, is approved as a
Category III venting system for Calcana installations where venting is required.
The venting system is to be provided by the installer. The use of readily available, single wall venting materials
with a thickness no less than 26 gauge is to be used.
If 26 gauge “C
-
vent” or galvanized “stove pipe” i
s selected,
each joint will need to be sealed with high temperature silicone as prescribed below, as well as the connection
will require a minimum of three (3) #8 sheet metal or self tapping screws to be used in a pattern such that each
screw is installed at a distance that is equal between the number of fasteners selected. If material other than
the aforementioned is employed, connect sections of material in such a fashion that each connection is secure
and sealed.
A minimum 36” (91 cm) length of 3”
(7.62 cm) (CAL-40A, 50A or CAL-75A) or
4” (10 cm)
(for all
models) single wall material, with a thickness no less than 26 gauge is to be installed at the exhaust end of
heater. This length can include elbows. If a portion of venting is to pass through a wall, installer can continue
the single wall vent as long as a combustible wall thimble is used to provide adequate clearance to
combustibles, or “B
-vent (and related accessories) can be used. If a portion of venting is to pass through a roof,
installer to use “B
-
vent” (and related accessories) for these
sections. Use approved chimney cap for vertical
installations and approved high wind terminal, as described below in subsection B and C for HORIZONTAL
VENTING. Installer is to adequately support vent system to prevent sagging in a manner that is in accordance
with codes for the area.
Installer is to make sure all flue joints are sealed. Use only suitable products equal to General Electric RTV106
or
Permatex 81160 High-Temp Red RTV,
Red High Temperature Silicone Adhesive Sealant (not supplied). Apply
a
minimum of ¼ “ x ¼” (6.35mm x 6.35 mm) bead
of silicone to each joint, and to each seam. The bead should
be applied to venting material with a smaller diameter as compared to the larger opening of the mating
material or in some instances, clamp, in such a fashion that when the joint is secured, the silicone is squeezed
between the two materials to form a sealed connection. Apply additional silicone if needed to accomplish a
sealed joint or seam.
Follow the silicone manufacturer’s instructions for curing, a
nd after the material has cured, the installer is to
perform a leak test on the venting system. A soap and water solution test, on the venting installed inside the
occupied space, can be used.
If seamed, 26 gauge “C
-
vent” material is used, seal
seam(s) with RTV high
temperature silicone. Once the installer is satisfied that the venting system is sealed, the heater can be placed
in permanent operation.
