TO REDUCE THE RISK OF FIRE,
ELECTRICAL SHOCK OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit in the manner intended by the manu-
facturer. If you have questions, contact the manufac-
turer at the address or telephone number listed at
the front of the manual.
2. Before servicing or cleaning the unit, switch o
at service panel and lock service panel to prevent
power from being switched on accidentally.
3. Installation work and electrical wiring must be done
by a qualied person(s) in accordance with appli-
cable codes and standards.
4. Sucient air is needed for proper combustion and
exhausting of gases through the ue (chimney) of
the fuel burning equipment to prevent backdraft-
ing. Follow the cooking equipment manufacturer’s
guidelines and safety standards and the local au-
thorities safety standards in the country in which the
grease fan is installed.
5. This unit must be grounded.
TO REDUCE THE RISK OF INJURY TO
PERSONS IN THE EVENT OF A CHIMNEY
FIRE, OBSERVE THE FOLLOWING:
1. Immediately close all dampers and/or air entrance
openings to the cooking appliance. This includes
doors.
2. Alert your building inhabitants about possible
danger.
3. Inspect your cooking appliance and chimney sur-
roundings for possible re. If in doubt, alert your re
department.
4. Do not continue to use your appliance until it and
your chimney have been thoroughly inspected.
Overheating can cause metal parts to expand,
buckle and crack. If you are not certain, have a certi-
ed chimney sweep disassemble all parts so they
can be inspected and cleaned.
5. Do not use salt or water on the re in the cooking
appliance. Salt is corrosive and water will cause a
dangerous steam explosion. You might be able to
control the re by using ashes, sand or baking soda,
since baking soda is an ingredient used for dry
chemical re extinguishers.
6. After a chimney re, when it is safe to do so, check
internal locations such as an attic and under the
roof and keep watching for two or three hours.
There may be delayed smoldering and subsequent
ignition, even if the re inside the chimney has been
controlled.
TO REDUCE THE RISK OF A CHIMNEY FIRE:
1. Keep chimney and grease fan clean.
2. Always turn ON fan when using the cooking appli-
ance.
3. Do not leave cooking appliance unattended when
in use.

3. Mechanical installation
3.1 Positioning
Considered a mechanical draft system, there are much dierent code requirements than for a gravity venting system or
grease ducts used with gas or solid fuel applications. As a general rule, the mechanical draft system must be installed min.
3 feet away from any forced air inlet located within 10 feet, and min. 4 feet away from any door or window. For complete
information, consult exodraft or your local building codes.
Adequate fresh air must be provided for combustion; otherwise, improper operation and
inadequate venting of deadly ue gases may result.
If you are installing the fan on an existing chimney system or grease duct, you must clean the
chimney or duct prior to installation.
Always use a certied chimney sweep to clean the chimney, duct and grease fan.
3.2 Installation on steel duct
yInsert the steel chimney adapter into the chimney where the long collar engagement ensures safe anchoring (see
Fig. 2). If necessary, the adapter can be secured by means of long self-tapping stainless steel screws into the side of
collar through the chimney wall. Do not obstruct the ow.
yTurn the exodraft fan upside-down and lay a bead of hi-temp silicon on the base close to the outer edge (not
shown).
yRemove the transport securing device (if present) holding the motor shaft and impeller in place.
yPlace the fan on the adapter with the fan inlet centered over the chimney outlet.
yOpen the fan and secure the fan onto the adapter, through the pre-drilled holes in the bottom, with lag bolts or
self-tapping sheet metal screws, one at each corner.
ySeal around the fan base to make sure it is watertight and no water can slip in between the fan and the adapter. Do
not block the 4 drain holes.

3001361 GSV009-016 Grease fan 20210824 - international

3.3 Installation on roof curb
If the fan is installed on a roof curb, the curb will do the same as the adapter.
Follow the instructions under 3.2
3.4 Installation on side wall
yMake sure the vent terminates ush with the wall. Insert the steel chimney adapter and secure it safely to the wall.
Seal around the edges of the adapter ange.
yMark the locations of the wall anchors and predrill holes for them.
yTurn the fan upside-down and lay a bead of hi-temp silicone on the base close to the outer edge (not shown).
yOpen the fan and secure the fan onto the adapter with wall anchors, through the pre-drilled holes in the bottom.
Make sure the conduit is located on one of the sides. Never on the upside or downside.
ySeal around the fan base to make sure it is watertight and no water can slip in between the fan and the adapter. Do
not block the 4 drain holes.
3.5 High temperature applications
yIf the fan is used for applications that exceed its temperature rating, dilution bolts must be used.
yInstall the dilution bolts in the outer holes of the fan base.
yAdjust the height of the dilution gap by adjusting the dilution bolts, so the temperature of the exhaust going
through the fan does not exceed the fan’s temperature rating.
yBe aware the dilution bolts will have a negative impact on the fan’s actual capacity and a stronger fan model may
be required. For more information, please refer to the installation manual a accompanying the dilution bolts.

4. Electrical installation
4.1 Electrical requirements
Power requirements are dependent on the fan size and can be found on page 6.
DANGER
Turn o electrical power before servicing. Contact with live electric components can cause shock
or death.
NOTICE
If any of the original wire supplied with the system must be replaced, use similar wire of the same
temperature rating. Otherwise, insulation may melt or degrade, exposing bare wire.
4.2 Wiring diagram
The connection diagram below shows how the exodraft fan is connected to the fan speed control and the power source

5. Start-up and conguration
5.1 System testing
yCheck the line voltage with the motor nameplate rating.
yDetermine if the axial vane is running free and has not been subject to misalignment in shipping or installation.
yTurn the exodraft grease fan ON and make sure that it is operating. Adjust the fan speed control to make sure it is
operating properly.
Prior to using a cooking appliance, make sure that sucient air needed for proper combustion
and exhausting of gases from oil/gas-red appliances, like water heaters, furnaces and boilers, is
provided.
yWith the fan ON, check that other heating appliances (furnace, water heater, etc.) are operating safely without spill-
age (spillage is the escape of ue gases from the relief opening of the draft hood of an atmospheric appliance). On
start-up, a little spillage is normal, but it must stop after a couple of minutes.
ySpillage can be detected by introducing smoke into the ue products ahead of the draft hood or by observing if
the ame of a match goes out when it is held at the edge of the draft hood relief opening (See Fig. 5).

5.2 Testing pizza oven operation
Most pizza ovens consist of a dome with a front opening that can be closed with a cast iron door. Above the opening, a
hood connected to the ue assures smoke and odors are collected and removed safely (see Fig. 6).
Place a few logs in the back of the dome and set the fan at high/full speed. Light the re. Turn on all exhaust fans (range
hoods, etc.) and make sure that there is no spillage from the hood into the room. When the re has caught on, reduce the
speed of the grease fan to a point where it still removes the ue gases safely. Mark this setting on the fan speed control
cover, as this will be the operating position/speed of the grease fan.

3001361 GSV009-016 Grease fan 20210824 - international

5.3 Adjusting fan speed
Start all heating appliances connected to the chimney fan installed. Set the fan speed control to the speed where no spill-
age is experienced anywhere in the system.
5.4 Operation of pizza ovens
Prior to starting a re, set the fan at high/full speed and start the re following the oven manufacturer’s instructions or, in
the absence of such instructions, follow normal instructions on burning a re in a replace or stove.
After the re catches on, after 3-5 minutes, reduce the speed of the grease fan to a level where it safely removes the ue
gases and a perfect ame can be maintained.
When adding wood to the re, it may be necessary to increase the fan speed for a short period of time.
Do not over-re the pizza oven. Small deposits of creosote could be ignited and start a small
chimney re which could cause the chimney ue to reach a hazardous temperature.

3001361 GSV009-016 Grease fan 20210824 - international

6. Maintenance and troubleshooting
6.1 Care and cleaning
The exodraft grease fan is designed for prolonged use. The fan should be inspected at least once a year when the chim-
ney is inspected. Deposits should be removed from the fan blades or the impeller and the bottom of the motor housing.
The run capacitor is considered a wear part and will need to be replaced depending on usage.
Fig. 7
The top of the fan is hinged and can be opened in order to ease the cleaning.
Do not open the motor housing unless power to the grease fan has been disconnected.
6.2 Chimney cleaning intervals
The need for chimney and chimney fan maintenance depends on how the cooking appliance is operated.
Pizza ovens and BBQ’s need a great deal of chimney and chimney fan maintenance. These appliances produce dense
smoke consisting of creosote and grease if it is loaded for long durations or overnight res.
6.3 Creosote formation and need for removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form
creosote. The creosote vapors condense in the relatively cool chimney ue of a slow-burning re. As a result, creosote
residue accumulates on the ue lining. When ignited, this creosote makes an extremely hot re.
Creosote causes many problems. Some are visible, while others are not. It can make trouble if:
yIt runs down outside the pipe to damage the nish on the metal.
yIt drips out of joints, damaging oors or furnishings.
yIt plugs up the chimney causing poor combustion, smoking, soiling walls and indoor pollution.
yIt catches re in the chimney to cause possible chimney damage and damage to the building.
6.4 Inspection schedule
The chimney and the chimney fan should be inspected at least every 2 weeks for the rst couple of months to determine
at what rate the creosote builds up. If creosote has accumulated, it should be removed to reduce the risk of a chimney re.
Evaluation of chimney systems installed in commercial restaurants serving a wood-red cooking
appliance indicates a build-up of 1/8-1/4”of creosote for every 4 cords of wood burned. This can
be used as a guideline, but each application is dierent.
As a guideline, a chimney and grease fan serving a commercial wood-red cooking appliance should be cleaned at least
once a month, unless the use has proven this to be more than adequate.
Most chimney manufacturers require, if you see deposits more than 1/16”thick, clean all chimney parts mechanically. This
means using brushes, scraping or equivalent.
12
3001361 GSV009-016 Grease fan 20210824 - international

Do not start a chimney re as a means to clean the chimney!
With only slight deposits, try a hot re to see if the black deposits fall down the chimney. You can hear the sound
of falling deposits when the temperature conditions are right. Afterwards, reinspect the chimney and the inside of the
oven for deposits.
Do not use chemical cleaners, they may corrode the inside of the chimney.
They may or may not prevent or remove the creosote. When they are used together with a hot re, it is probably the re
that is doing the work.
Depending on the rate of build-up, as you learn what is going on in the chimney, you can adjust your cleaning schedule.
If you have doubts about your ability to clean the chimney, or if the deposits are very heavy and hard to
remove, do not try to burn them o. Call a professional, certied chimney sweep.
It does not matter how careful you are loading fuel, selecting wood or controlling draft, you should always observe the
above precautions with any solid-fuel burning cooking appliance.
6.5 Chimney res and what to do about them
No chimney or chimney fan is intended or designed for use as a combustion or re chamber. It is very easy to overre a
wood burning oven with kindling, scrap, lumber, brush or any fast burning fuel. This can produce ames and high tem-
peratures all the way up the chimney and may cause chimney fan damage.
The creosote may be burning inside the chimney. If you can see ames coming out of the top, you are either over ring or
there is a chimney re.
If the re in your cooking appliance/chimney has gotten out of control, or if you suspect a chimney re for any reason,
follow these steps:
1. Immediately close all dampers and/or air entrance openings to the cooking appliance. This includes doors.
2. Alert your patrons to the possible dangers.
3. Inspect your cooking appliance and chimney surroundings for possible re. If in doubt, alert your re department.
4. Do not continue to use your cooking appliance until it and your grease fan have been thoroughly inspected. Over-
heating can cause metal parts to expand, buckle and crack. If you are not certain, have a certied chimney profes-
sional disassemble all parts so they can be inspected and replaced, if necessary.
5. Do not use salt or water on the re in the cooking appliance. Salt is corrosive and water will cause a dangerous
steam explosion. You might be able to control the re by using ashes, sand or baking soda, since baking soda is an
ingredient used for dry chemical re extinguishers.
6. After a chimney re, when it is safe to do so, check internal locations such as an attic and under the roof and keep
watching for two or three hours. There may be delayed smoldering and subsequent ignition, even if the re inside
the chimney has been controlled.
