GENERAL INSTALLATION NOTES
1
1. The chimney is intended for use with solid (6’’,7’’,8’’ dia. only) or
liquid and gaseous fuel burning appliances.(all diameters)
Allowable flue gas temperature:
Maximum continuous 540°C (1000°F)
Brief forced firing 760°C (1400°F)
Tested to 1150°C (2100°F) - 30 minutes
2. On wood or coal stove application and in area where the chimney
is completely enclosed, it is required to install Premium shields
(telescopic of flexible) around the chimney and a Radiation shield
connector at the ceiling level.
For venting of gas or oil burning appliances Premium shields are
not required even where the chimney is enclosed.
For factory-built wood burning fireplaces, Premium shields
are usually not required, please follow fireplace installation
instruction.
3. The maximum height of chimney supported by the various supports
are outlined on page 3.
4. The supports described in this booklet should only be used with
Duravent model DURATECH CANADA (DTC), 5", 6", 7", 8" and 10"
factory built chimneys.
5. Size the chimney in accordance with the appliance manufacturer's
instructions.
6. When a firestop (DTC-FS , DTC-ISI or DTC-RSCI) needs to be
installed, it is important to follow the opening dimensions for the
floor openings prescribed in this manual. This way, the holes left
by the folded positioning tab of the firestop will be blocked by the
ceiling.
7. A chimney servicing a fireplace or an incinerator shall not serve any
other appliance.
8. The chimney shall extend at least 3 ft above its point of contact
with the roof and at least 2 ft higher than any wall, roof or adjacent
building within 10 ft of it.
9. The maximum height of unguided chimney above the roof is 5 ft.
10. The clearance between single wall pipe and unprotected combustible
material must not be less than 18" (see national building code and
NFPA 211) except: The distance between the vertical stove pipe and
the ceiling may be less than 18" and will be established by the finish
support.
11. Portions of the chimney which may extend through accessible
spaces shall be enclosed in all cases to avoid personal contact
with the chimney and damage to the chimney. When doing so on
woodstove or coal application, a telescopic or flexible Premium
shield must be installed (see Figure 2). Except for installation in
single and two-story family dwellings, the enclosure must have a
fire resistance rating equal to or greater than that of the floor or
roof assemblies through which they pass.
12. Do not fill the 2" space around the chimney with insulation or any
other material. Insulation placed in this area could cause adjacent
combustibles to overheat.
13. Self tapping screws are not required, but may be used to reinforce
the connection and avoid accidental unlocking of chimney lengths.
