WARNING
TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK, OR INJURY TO PERSONS:
1. Use this unit in the manner intended by the Manufacturer. If you have questions or concerns, please
contact Denlar Service at 860-526-9846 or se[email protected].
2. Before servicing the Hood, turn off power at the Main Breaker Panel. Ensure the Breaker is locked-
out/tag-out in accordance with local codes.
3. It is required that installation work and electrical wiring is performed by a qualified person in
accordance with local codes and standards, including fire rated construction codes and standards.
4. Sufficient air flow is needed for proper combustion and exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent back-drafting. Follow the heating and equipment
manufacturer’s guidelines and safety standards such as those published by the National Fire
Protection Agency (NFPA), and the American Society of Heating Refrigeration and Air Conditioning
Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into the wall or ceiling, do not damage electrical wiring or other hidden
utilities.
6. To reduce the risk of fire or electrical shock, do not use the Hood with an additional speed control,
unless provided by the manufacturer.
7. Ducted fans are required to be vented outdoors.
8. To reduce the risk of fire, use metal duct work based on local code and guidelines.
9. Use with approved wiring.
10. The Hood is required to be Grounded.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
1. Never leave surface units unattended. Boilovers cause smoking and greasy spillovers that could
ignite. Heat oils slowly on Low or Medium settings.
2. Ensure the Hood’s Fan is energized when cooking at a High setting or flambéing food (i.e. Crepes
Suzette, Cherries Jubilee, and others).
3. Clean ventilating fans frequently. Do not allow grease to accumulate on the fan filter.
4. Use cookware that is the appropriate size for the surface element.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE:*
1. Smother Flames with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. Be
careful to prevent burns . If the flames do not go out immediately, evacuate and call the fire
department.
2. Do not pick up a flaming pan, this could cause burns to the person.
3. Do not use water, including water clothes or towels; this will cause a violent steam explosion.
4. Use an extinguisher if:
a. It is a K Class Extinguisher.
b. The fire is small and contained in the area it started.
c. The fire department is called.
d. The fire can be extinguished with the persons back facing the exit.

The Hood has two options for mounting. There are four mounting holes in the top and rear of the unit. If
a cabinet is installed above the Hood with top discharge or an inline fan, then a 7” hole is needed in the
cabinet. If a Hood has a Manual Pull Station (MPK), then a 0.85” diameter hole is needed. See Cabinet
Bottom View for the placement of the holes
needed.
There are four knockouts (KO) for the
input and output power. It is
recommended to use the two KO’s on
the right side of the hood, next to the
side cover. This allows the wiring to
be installed in a more efficient
manner.

The Designer Series Hood is equipped with two switches. The Switch on the right is for the two lights in
the Hood. The switch on the left is for the fan
motor. This switch is a three-position rocker switch.
The positions are marked “O”, “I”, and “II”. The “O”
marking keeps the fan motor off. The “I”marking
sets the fan motor to low speed. The “II”marking
sets the fan motor to high speed. If the Hood is
equipped with an inline external fan motor (DS-30-
D-IF) then the fan switch is an ON or OFF switch, there is no speed control.
There is a reset button located on the
Hood, this is to ensure someone is
available to light the igniters if they are
not automatic and prevent an accident. If
the Hood loses power, the reset button is
needed to be pressed again to open the
valve or close the coil of the electrical
disconnect. The reset button is a black
round push button located on the side
cover of the Hood.
If the Hood discharges, the microswitch powering the power disconnect changes states and shuts off
power to the power disconnect. An audible buzzer will sound. To reset the system, a new charged tank
assembly would need to be installed. The Tanks cannot be recharged in the field.
