1. Product information
1.1 Function
Use The exodraft model RS chimney fan is a chimney top mounted ventilator that is designed to provide large ue
gas volume capacities. It is designed and intended for use with residential gas or oil red central space heating
systems, for volume water heating or for combination space heating/volume water heating. It is also suitable for
use with gas-red replaces, stoves, BBQ’s or residential pizza ovens.
This product is developed to prevent draft problems from occurring by creating a mechanical draft in venting
systems and thereby also increasing the capacity and eciency of a venting system.
The use of the RS Chimney Fan is not restricted to any type of chimney, because the fan creates a negative
pressure (below atmospheric) in the chimney or vent.
Code compliance Installations must conform to requirements of the authority having jurisdiction.
All electrical wiring must be in accordance with the requirements of authority having jurisdiction.
Listing The RS is tested and listed to UL Standard 378, Standard for Draft Equipment. The fan is manufactured at an
ISO9001 certied plant and bears the European CE compliance label.
The chimney fan must be interlocked with the connected appliance(s) to insure proper combustions and to
avoid ue gas spillage.
1.2 Shipping
The packing list (attached to one of the packages) clearly lists all items in the shipment and each package has a label showing the
contents. Check the list against all materials on the job site for completeness.
NOTE: All single phase fans are shipped with a capacitor and junction box connected via conduit. The

2.2 Planning ahead
1. Observe proper combustion air requirements.
2. Provide a rm support system for the chimney fan.
3. Determine the type of system involved.
4. Observe proper safety measures are taken to assure safe use of the wood burning appliances
Combustion air requirements:
Provisions for combustion air must be in accordance with applicable local codes.
If the heating system is installed in an unconned space, adequate air will be available via normal inltration.
If the heating system in installed in a conned space, (a space with a volume less than 50 cubic feet per 1,000 Btu/hr of input for all
fuel burning equipment) or building construction is unusually tight, adequate air for combustion must be provided by two openings: one
located about 6”below the ceiling, the other about 6” above the oor.
Each opening must have a minimum free area as follows:
1. One square inch per 4,000 Btu/hr of input when communicating directly with the outside or through a vertical duct.
2. One square inch per 2,000 Btu/hr when communication through horizontal ducts to the outside.
3. One square inch per 1,000 Btu/hr when ventilation air is provided by openings in doors, etc. to adjoining spaces having adequate
inltration.
CAUTION
Adequate fresh air must be provided for combustion; otherwise, improper operation and
inadequate venting of deadly ue gases may result.
Support system for the exodraft chimney fan
Prior to installation of the chimney fan, it must be assured the chimney can safely carry the weight of the chimney fan.
A steel chimney should be well supported at the roof penetration point. If the chimney extends more than 20’ above the roof, the
chimney and the fan should be secured by wires attached on the chimney and on the roof at 2 to 3 dierent points.
Brick chimneys usually do not need any kind of support to carry the weight of the chimney fan.
System type
Direct connect oil or gas appliances (no draft hood) normally do not require any mechanical draft adjustment. However, if there are long
horizontal breechings and far between the appliances, it is a good idea to install mechanical vent dampers, so adjustments of the draft
can be easily made.
Draft hood systems could generally speaking have vent dampers installed. The vent dampers are used to balance the system and assure
that only a minimum of dilution air is pulled through the draft hoods.
Safety devices
Local codes usually require installation of safety devices, when mechanical draft is provided in an oil or gas fueled system.
Make sure a dierential pressure switch (proven draft switch) is installed to assure that no appliance will re unless there is a proven draft.

3. Mechanical installation
3.1 Transport safety device
If a transport safety device is present, remove it from the vane and make sure that
the vane can revolve without hindrance.
RS 14/16: Before mounting, the transport safety device on the hinges must be
removed.
3.2 Single fan on steel chimney
Step 1: Prepare fan location
yIf a stack cap is already installed, it must be removed. The steel chimney
adapter (SCA) slides right into the chimney, where the long collar engagement
ensures safe anchoring. If necessary, the adapter can be secured by means of
long self-tapping stainless steel screws into the side of the collar through the
chimney wall.
NOTE: If the steel chimney is air cooled, a special adapter
for such chimney must be used.
yMeasure the inside diameter of the ue and cut a corresponding hole in the
center of the ber mat. If the ue is so big that the throat in the adapter has
been reduced to t the throat of the fan, the hole in the ber mat should
correspond to the throat.
Step 2: Preparation of fan
yLocate the installation brackets in the grooves on the underside of the fan
base, using the bolts and nuts supplied to secure the brackets. Note that the
bolts shall be installed from the bottom side in the two inner holes.
yAdjust the nal position of the installation brackets ensuring that there is a
small gap between the brackets and the ue wall/adapter throat. Tighten the
nuts. If the brackets touch the ue wall, it may create some vibration noise.
Step 3: Attaching the fan
yThe exodraft chimney fan is now ready for installation on the top of the
chimney. Place the ber mat on the top of the adapter, and place the fan on
top of the mat. High temperature silicone can be applied on the side of the
mat, but is not required. It can also be painted. It is not necessary to bolt the
fan to the chimney.
CAUTION
Under conditions with extremely strong winds
surrounding the top of the chimney, the chimney fan must be secured by steel wires supplied with
the fan.
6
3000270 RS gas and oil 20210818 - international

3.3 Single fan on brick chimney
Step 1: Prepare fan location
yThe installation procedure is the same whether the ue is round or square. If a
clay tile ue liner is installed, it might stick up a few inches. Cut it back so it is
ush with or no more than 1/2‘‘ above the chimney crown.
yMeasure the inside diameter of the ue, cut a corresponding hole in the ber
mat leaving a minimum distance of 3/4”to any side of the ber mat.
Step 2: Preparation of fan
yLocate the installation brackets in the grooves on the underside of the fan base
using the bolts and nuts supplied to secure the brackets. Note that the bolts
shall be installed from the bottom side in the two inner holes.
yAdjust the nal position of the brackets ensuring that there is clearance
between the brackets and the ue wall. If the brackets touch the wall, it may
generate some vibration noise.
Step 3: Attaching the fan
yThe chimney fan is now ready for installation on the top of the chimney. Place
ber mat on the top of the chimney, and place the fan on top of the mat. High
temperature silicone can be applied on the side of the mat, but is not required.
It can also be painted. It is not necessary to bolt the fan to the chimney.
Caution
Under conditions with extremely strong winds surrounding
the top of the chimney, the chimney fan must be secured by
steel wires supplied with the fan.
7
3000270 RS gas and oil 20210818 - international

3.4 Multiple fans on steel chimney
yIf two or more chimney fans are required to create sucient draft, installation
procedures are the same as for single fan installation on a steel chimney. The
only dierence is that the fans are sitting next to each other on the top of the
chimney. A special adapter plate is required.
yWhen installing multiple fans, it is extremely important that the fans are of
the same model and size, and they must be controlled in tandem by one (1)
motor speed control.
3.5 Multiple fans on a brick chimney – Oversized ue
yIf two or more fans are required to create sucient draft, a special adapter
plate is required. The adapter plate should be made of stainless steel (14 GA
or thicker), depending on the size and the fan models used.
yThe two holes in the plate should match the throat diameter of the fan
model used and the distance from center to center should be at least equal
to the fan width (dimension Bin 2.1. Dimensional Data).
yThe adapter should be sealed with silicone and bolted onto the top. When
installing multiple fans, it is extremely important that the fans are of the
same model and size, and they must be controlled in tandem by one (1)
motor speed control.
yA similar approach should be taken if the ue size exceeds the fan base
dimensions. The adapter plate should be sized so it covers the ue and
secured. A hole should be cut in the center of the plate and the fan mounted
centered over the hole.
3.6 Installation for high temperatures
yif the fan is used for applications where the ue gas temperatures exceed
400 °F at the ue exit, and does not exceed 650 °F, dilution bolts must be
used.
yDilution bolts will cause cool air to dilute the warm ue gas, by lifting the fan
and leaving space so the cool air can get in under the fan base.
yThe dilution bolts should be installed in the outer holes in the fan base.
yThe dilution bolts are adjustable and should be adjusted so the ue gas
temperature does not exceed 400 °F when discharged through the fan. When
using dilution bolts the fan’s actual capacity is reduced and a stronger model
may be required. The ber mat is not required when using dilution bolts.
8
3000270 RS gas and oil 20210818 - international

3.7 Wall mounting of chimney fan
yWhen mounting the chimney fan on a wall, the installation instructions for
installation on a steel chimney should be followed. Use of the adapter SCA can
make the installation easier, but is not a requirement.
yTo ease installation, detach the fan base by removing the bolts holding the hinges
together. Center the fan base over the outlet and bolt the base onto the wall with
the hinges pointing upwards.
yAfter mounting the base securely, attach the fan motor housing by reassembling
the fan hinges. Seal with silicone all around the ber mat to prevent rain from
entering the ue.
3.8 Installation of Proven Draft Switch (PDS)
yA safety system must be interlocked with the appliance(s). The safety system could
utilize a Proven Draft Switch, a thermal switch or a ow switch. The device must be
interlocked with the heating appliance so it shuts down in case of insucient draft,
fan failure or power failure. Please refer to the PDS Installation Manual if this control
is used.
yFor more information on alternative safety systems, please contact exodraft a/s.
yThe gure shows the location of the probe for the PDS. Location is important to
make sure there is enough pressure or draft available for the switch to work.
NOTE
A safety device that prevents the heating appliance operation, in case of a power failure or
inadequate draft situation, must be installed.

5. Start-up and conguration
5.1 System testing
Before any adjustments are made to the system, follow these procedures:
1. Turn the exodraft chimney fan ON and make sure that it is operating. Increase and decrease the speed of the fan by adjusting
the fan speed control to make sure it is operating properly.
2. Turn the fan OFF and make sure the pressure switch opens, so the power to the circuit, it controls, is disconnected.
DANGER
Check other heating appliances (water heater, furnace, replace etc.) for proper operation while
the chimney fan is operating. Make sure no ue gases are spilling out as this can lead to carbon
monoxide poisoning.
5.2 Adjusting the chimney fan speed
yStart up all appliances. Use the fan speed control to set the speed of the chimney fan so no back pressure is experienced
anywhere in the system. Check the system for ue gas spillage. Mark this setting on the fan speed control cover.
5.3 Adjusting the Proven Draft Switch setting
yRemove the snap-on cover from the conduit enclosure by loosening its retaining screw. Turn the slotted Adjustment Screw
clockwise to raise the set point pressure and counter clockwise to lower the set point.
ySet the adjustment to its lowest position. With all appliances operating, reduce the speed of the fan to the set point, where the
appliance(s) starts to spill ue gas. Increase the speed of the fan gradually to the point where there is no more spillage. Raise the
switch’s set point so it opens. Return the fan speed to the original setting marked on the cover.
yThe system is now adjusted so the ue gas spillage will disconnect the heating appliance(s).
yThe procedure described here may not cover all Proven Draft Switches, so please review the Installation Manual for the switch
being used.

6. Maintenance and troubleshooting
6.1 Prior to cleaning
Remove buttery nut or screw from each hinge prior to cleaning if still attached.
6.2 Care and cleaning
The exodraft Chimney Fan is designed for prolonged use. The fan should be
inspected at least once a year when the chimney is inspected. Fuel residues and
other deposits should be removed from the fan blades and the bottom of the motor
housing.
The top of the fan is hinged and can be opened in order to ease the cleaning.
The run capacitor is considered a wear part and will need to be replaced depending
on usage.
WARNING
Do not open the motor housing unless power to the chimney fan has
been disconnected.
6.3 Chimney cleaning intervals
It is extremely important to keep the chimney ue clean from products of combustion and deposits. Soot can cause a chimney re.
Cleaning intervals depend on the use of the appliance. The more the appliance is used, the more often the chimney ue needs
cleaning. As there are no rm guidelines for cleaning intervals, have the chimney inspected on a regular basis (every quarter or so) to
determine what the interval should be. Then follow this interval.
No matter how much it is used, a chimney ue should be cleaned and inspected at least once every year.
Note
The chimney should be cleaned by a trained professional.
Remove Butterfly Nut or
Screw from each Hinge
