Product information
The Exodraft Bypass Damper is used in exhaust systems to control the hot ue gases/process air to the
Basic Plate heat recovery devices.
A Bypass Damper is used primarily for larger boiler systems, industrial processing plants, or commercial
systems. An integrated electric motor opens and closes the damper.
Power supply and start/stop signal come from an external Exodraft panel, and is not a part of the Bypass
Damper.
The Bypass Damper has a safety spring return, causing it to close automatically in case of a power failure.
All parts affected by ue gas are made of stainless steel EN 1.4404.
All exterior parts are made of stainless steel EN 1.4301.
The Bypass Dampers limitations
• The Bypass Damper is not to be used as a draining point in an exhaust system.
• As a rule, the Bypass Damper is only for indoor installation.
Installation outside requires extra shielding.
• Max. temperature 600°C
• Flue gas/process air must be of a quality (particle free) that will not, over time, cause the damper to be
lled with residue that can affect the function of the damper.

Mechanical installation
Exodraft products must always be installed by properly qualied personnel.
These instructions, applicable standards and relevant safety procedures from the manufacturer must be
followed and at the same time the ofcial provisions in force in the country, where the product is installed,
must be observed.
CAUTION! If the Exodraft Bypass Damper is not installed, maintained, and/or operated in compliance with the manufac-
turer’s instructions, conditions may arise which could lead to personal injury or material damage.
Placement and orientation
You must allow for hot surfaces on the Bypass Damper. If Bypass Damper is placed where it is easily acces-
sible, it must Be Aware of hot to avoid inadvertent touch and any risk of inadvertent touch.
The damper motor on the Bypass Damper can be installed on the left or right side.
DANGER! Observe national regulations regarding distance from ammable materials.
If Bypass Damper is placed where it is easily accessible, it must be shielded to avoid inadvertent touch and
any risk of collision.

Connection
• Connection on heat exchangers is 1 1/4” outside thread
• Connection to drain is 1” inside thread
• Connection to measuring points is ½” inside thread
CAUTION! Bypass Damper comes with heat exchangers temporarily mounted for shipping. When installing, the included
gaskets, nuts, and washers must be tted. Tightening the exchanger is done as shown on the illustration below. Nuts are
tightened crosswise to 20 Nm.

When selecting gasket material, keep in mind that the temperature for drains and measuring points can be
the same as the temperature of the ue gas.
We recommend installing a water trap on the drain connection. The water trap should be placed a good
distance from the Bypass Damper to avoid the water evaporating.
DANGER! The safety thermostat must be must be tted on the supply side.
Pressure relief valve must be tted to the water circuit.
See recommended systempressure in section about Maintenance and Troubleshooting.
CAUTION! If the drain is connected to the sewer system, you must ensure that condensate complies with any emission
requirements.
Installation without water connection
If Bypass Damper is installed without water connection, the exchanger must be pulled out and a cover plate
installed (if needed see section about Optional Components).
Tightening of the exchanger cover plate is done as shown in the illustration. Nuts are tightened crosswise
to 20 Nm.
