WARNING:
TO REDUCE THE RISK OF FIRE, ELECTRICAL
SHOCK OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:
A. Use this unit only in the manner intended by the
manufacturer. If you have any questions, contact the
manufacturer.
B. Before servicing or cleaning unit, switch power off
at the service panel and lock service panel to prevent
power from being switched on accidentally. If the
service panel cannot be locked, fasten a tag or
prominent warning label to the panel.
For general ventilating use only. Do not use to
exhaust hazardous or explosive materials or vapors.
Structural framing, installation work and electrical
wiring must be done by qualified person(s). In
accordance with all applicable codes and standards
including fire-rated construction.
Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent back drafting.
Follow the heating equipment manufacturer’s
guideline and safety standards such as those pub-
lished by the National Fire Protection Association
(NFPA), and the American Society for Heating,
Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
Local codes vary. Installation electrical connections
and grounding must comply with applicable codes. In
the absence of local codes, the vent should be
installed in accordance with National Electrical Code
ANSI/NFPA 70-1990 or latest edition.

REQUIRED ACCESSORIES
This book provides step by step instructions to install the
Monogram ZV850 ceiling mounted hood for recirculat-
ing operation.
• One of the following accessory kits is required for non-
vented ceiling mounted installations of model ZV850.
Choose the correct kit according to ceiling heights:
ZXR858 – For 8 ft. ceiling height.
ZXR859 – For 9 ft. ceiling height
ZXR8510 – For 10 ft. ceiling height.
• Order the required accessory at the same time as the
vent hood and have on site before installation.
• Each kit includes decorative duct covers, a support
frame, air deflector and charcoal filters.
PRODUCT DIMENSIONS
The vent hood must be installed 24” min. and 30” max.
above the cooking surface. 25-1/2” is recommended for
best performance and to insure that the duct cover
meets the ceiling. The cooking surface should be at least
36” above the floor. Installation will be easier if the vent
hood is installed before the cooktop and countertop is
installed.

* The distance between the cooking surface and the bottom of the
hood must be at least 24” and up to 30” The 25-1/2” recommended
installation height, above the standard 36” countertop, will insure
duct cover fit to the ceiling.

POWER SUPPLY
IMPORTANT - (Please read carefully)
WARNING:
FOR PERSONAL SAFETY, THIS APPLIANCE MUST
BE PROPERLY GROUNDED.
Remove house fuse or open circuit breaker before
beginning installation.
Do not use an extension cord or adapter plug with
this appliance. Follow National electrical codes or
prevailing local codes and ordinances.
Electrical supply
This vent hood must be supplied with 120V, 60Hz,
and connected to an individual, properly grounded
branch circuit, and protected by a 15 or 20 amp
circuit breaker or time delay fuse.
• Wiring must be 2 wire with ground.
• If the electrical supply does not meet the above
requirements, call a licensed electrician before
proceeding.
• Route house wiring in the ceiling, as close to the
installation location as possible. Allow an addi-
tional 3 feet length from ceiling joists to reach the
junction box on the hood.
• Connect the wiring to the house wiring in accor-
dance with local codes.
Grounding instructions
The grounding conductor must be connected to a
ground metal, permanent wiring system, or an
equipment-grounding terminal or lead on the hood.
WARNING: The improper connection of
the equipment-grounding conductor can result in a
risk of electric shock. Check with a qualified electri-
cian or service representative if you are in doubt
whether the appliance is properly grounded.

– The framing should be spaced 8-5/8" on the sides and 7-5/8" at
the front from centerline to centerline to accept mounting
screws in the vent support frame.
Note: The cross framing must be spaced 8-3/4" on the side from
centerline to centerline in order to accept the hood mounting
screws.
INSTALL CEILING
SUPPORT STRUCTURE
• At the hood location, install 2 x 4 cross framing
between ceiling joists as shown.
• The 2 x 4 cross framing can be installed standing or
flat. See illustration.

Joist
• The cross framing must be level in all directions.
Check with a spirit level and adjust if necessary.
MPORTANT: The ceiling structure must be capable of supporting
the weight of the hood (approximately 100 pounds) and any
inadvertent user contact loads. It is recommended that the hood
support frame be supported by a minimum of 2 x 4 cross framing.
Finish the Ceiling
Once the ceiling is finished mark the location of the
ceiling joist and cross framing.
• Check to be sure that ceiling is level, use shims if
necessary.
• Arrange cross framing in the ceiling to suit the
existing structure. See examples.
– Secure each 2 x 4 block with at least four (4), #10
wood screws, 3” long (minimum size screws, not
supplied). Use 8 wood screws total for the two
supports.
• The cross framing must be accurately aligned to
assure correct positioning of the hood.
1MOUNT TEMPLATE
• Align the template with the marks on the ceiling
and tape in place.
– Be sure the template is oriented correctly, with the
front of the hood.
• Use a plumb to check to be sure the mounting
holes will provide parallel alignment with the
countertop below.
• Center punch all hole
locations.
• Drill pilot holes in the 4 screw
locations. Use a 5/32” bit and
drill approximately 1-1/2”
deep.
• Cut wire access hole
approximately 1" dia.

3INSTALL LOWER SUPPORT
FRAME
• Insert lower support frame (from required acces-
sory ZXR858, ZXR859 or ZXR8510) into the upper
support frame and loosely secure with 8 screws and
washers (4 on the front and 4 on the back sides).
• Adjust the lower support frame up or down to the
desired height above the countertop. Tighten
screws.
2INSTALL UPPER SUPPORT FRAME
• Install the plastic upper duct connector to the
upper support frame by inserting from the bottom
and snapping into the opening of the air deflector
(already installed).
• Secure the upper support frame to the ceiling joists
and/or cross framing with the 4 screws provided.
For maximum rigidity and strength, the screws must
be driven into the center of the joists and/or cross
framing.
• Check to be sure the support frame is level,
vertically and horizontally.
Important: Again, check to be sure the support is
level in both directions. There is no way to level the
hood after the hood is secured to the frame.

– Subtract 1-3/4" for hood insertion into the bottom
of the frame.
• Cut the 6" dia. duct to the required length.
4SECURE WIRING
• Route house wiring through the ceiling hole and
pull a length to reach the hood junction box,
approximately 6” below the support.
Note: The top and bottom of the duct are external
(female) connections. The bottom end should be
flared slightly, to facilitate installation of the hood.
• Install duct up through support frames onto the top
duct connector. Push duct up until it is 1-3/4" from
the bottom of support frame flange. See illustration.
