The manufacturer declines all
responsibility in the event of failure
to observe the instructions given
here for installation, maintenance
and suitable operation of the
product. The manufacturer further
declines all responsibility for injury
due to negligence and the warranty
of the unit automatically expires due
to improper maintenance and/or
installation.
BEFORE YOU BEGIN:
It is advisable to test run the
range hood before installation.
1
BEFORE STARTING – please read
this entire document and ensure you
are fully conversant with the require-
ments and limitations. These units
weigh approximately 125lbs and
therefore require a minimum of two
people to install. Remove the filter
from the hood so that it does not get
damaged during installation.

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
25” for electric
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.
This unit must have it’s own duct
w o r k . D o n o t u n d e r a n y
circumstances vent this unit into any
other ductwork or exhaust ducting in
the building.
PLEASE NOTE THAT THE DUCT
OUTLET ON THE TOP OF THE
POWER UNIT IS OFF SET FROM
CENTER AND THEREFORE AN
ADJUSTABLE 6” ROUND BEND
WILL BE REQUIRED TO LINE THE
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
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
