Min length of power unit structure with deflector connected = 38"
Min length of power unit without deflector = 33"
Max length of power unit structure = (SIU3, SIU4)= 48", (SIU5)=50", and
(SIU8)=47"
Recommended height from cook top to underside of hood = 30" for gas
If vented externally, 6" / 150mm
round ducting must be available for
the hood through the ceiling, in line
with the central vertical axis of the
range hood.

declines all BEFORE STARTING – please read
this entire document and ensure you
are fully conversant with the require-

EXHAUST OUTLET WITH THE 6"
HOLE IN THE CEILING MOUNT
BRACKET.
Use the shortest most direct duct
work route possible. Only use metal
ducting - plastic ducting is generally
u n d e r a n y
not permitted by code. Do not use
flexible metal ducting as the ridges
of the ducting cause severe air
turbulence and will significantly
reduce the efficiency of any hood -
THIS TYPE OF DUCTING WILL
REDUCE EFFICIENCY BY 50%.
Vent hoods may interrupt the proper
flow of exhaust gases from fire-
places, gas furnaces and gas water
