SCOTTY SS – INSTRUCTION MANUAL
Scotty SS Nov-05 13
Connect only to a flue or chimney capable of maintaining a negative draft of .05” w.c. at
all times and conditions.
WARNING: If this setting is exceeded it could cause a solid fuel fire to burn out of
control.
We recommend that the KERR SCOTTY SS Wood Furnace be connected to its own
chimney. However, two or more fuel-fired appliances, other than fireplaces, wood
stoves or incinerators, may be connected to the same chimney.
The National Standard of Canada, Installation Code for Solid-Fuel-Burning Appliances
and Equipment, CSA-B365-01 clause 5.2.9 states that:
Two or more appliances shall not be connected to the same chimney flue unless:
a. The appliances are located on the same story;
b. A negative pressure is maintained at the flue collar of each appliance;
c. Each appliance is provided with a means to control the rate of flow of air
or flue gases through the appliance combustion and heat exchanger
chambers. Where limitations on flue pressure (draft) are contained in the
manufacturer’s instructions, such means shall be capable of maintaining
at the flue collar, the pressure specified by the appliance manufacture;
NOTE : For the purpose of this Clause, draft controls include ash pit air
control dampers, dampers or draft slides wherever located, over-fire and
flue pipe key dampers, and check draft controls located on or in the flue
pipe.
d. The flue pipes of the appliances are connected to a manifold as close to
the chimney as practicable or directly to the chimney in the following
order:
(i) If only solid fuel is used, the flue pipe from the smallest appliance shall
be on top (downstream);
(ii) If different fuels are used as permitted in Clause 5.2.7 CSA-B365-01,
the oil flue pipe shall be on top (downstream); and the solid fuel flue
pipe on the bottom (upstream); and
e. The chimney flue is capable of venting the flue gas by natural draft when
all appliances not interlocked to prevent simultaneous firing are firing at
their maximum rate at the same time.
When installing a wood-burning appliance to an existing chimney carefully inspect entire
chimney for the presence of old inlet holes, which may be improperly covered by metal
caps or other unacceptable means. Fill any openings with brick and mortar to ensure
no hazardous openings exist.
