Smoke Loss Into The Kitchen– Cont.
Symptom
The Ventilator is not
exhausting all the
smoke, heat and
grease properly –
Cont.
Table T-5-2-1
Probable Cause
E. Inadequate make-up air
F. Exhaust fan discharge
G. Baffle #1 (Damper) not open to the
operating position (N/A on CG3-UVi-SPC-
FDD, CG3-UVi-SPC-FDT, and CG3-UVi-
SPC-ND).
Corrective Action
1 Make-up air must be supplied for
replacement of air exhausted
through all kitchen exhaust
systems. Refer to page 6-5 for
guidance.
2 A general "rule of thumb" is that
60% of the replacement air should
be fresh, conditioned, (heated or
cooled) air brought into the kitchen
area, with the remaining 40%
allowed to flow into the kitchen
from adjacent areas. Refer to
page 6-5 for guidance.
1 There should be no screen over the
discharge. If one is found, it should
be removed.
2 The direction of discharge should
not be into the prevailing winds or
downward onto the roof. A vertical
discharge is highly recommended.
1 Check outputs # 17 and 18 in the
Command Center for voltage.
Fan On = 0 VAC
Fan Off = 24 VAC
