You will need to create a secure soffit structure to mount the Island Vent Hood to
the ceiling. We suggest using
1 1/2 “ by 3 1/2 “ wood cut to fit the installation as
shown in the following pages. The soffit mounting to the top of the Island Vent Hood
will be
10 7/8 “ in length for the DCS-IVH-48 and 10 3/4 “ for the DCS-IVH-36.
These dimensions allow room for a 1/2 drywall duct cover. Do not deviate from
these dimensions when choosing a duct cover as the soffit structure must align with
the mounting holes on the Island Vent Hood. You are limited to a maximum of 1/2
inch on all sides.
NOTE: You will need to determine which type of duct cover will be used before
installation and leave enough space around the soffit for a flush mount between the
duct cover material and the top of the Island Vent Hood.
CAUTION- When installing the ISLAND VENT HOOD directly to the ceiling, adequate
structural supports are CRITICAL to secure the unit. The Island Vent Hood is heavy,
weighing 128 LBS for the DCS-IVH 48 and 94 LBS for the DCS-IVH-36.
NOTE: The soffit height will vary according to the ceiling height.
GENERAL INSTALLATION GUIDELINES:
1) Determine the location for installation.
2) Determine the centerline of the installation.
3) If drywall is installed, cut away enough drywall to expose 2 ceiling joist (1 on
each side of the Hood center line)
4) Create your soffit structure according to ceiling height and attach soffit plates
for DCS-IVH-36 or soffit brackets for DCS-IVH-48 with screws to sides (see the
following pages for soffits and construction).
5) Attach soffit structure to existing ceiling joist.
6) Secure soffit with soffit braces according to model type (see diagrams page 7-
10).
7) Attach Island Vent Hood to soffit with the six 2 inch mounting screws provided.
Once the Island Vent Hood has been mounted in place it will be necessary to install
the electrical service. All electrical work should be done by a qualified electrician and
must conform to all local standards. Refer to the wiring diagram on Pg. 13 for proper
hook-up and grounding.
NOTE: Black=live, White=neutral, Green=ground
Complete the installation by making ductwork connections, testing unit functions,
and installing & finishing drywall.
