INSTALLATION INSTRUCTIONS

Safety

Barometric dampers should only be connected to non­positive pressure appliances. Non-positive pressure
appliances include gas, oil, and solid fuel appliances.
Barometric Dampers shall be installed in the same room as
the appliance it is serving.

Warning:
Install barometric dampers in accordance with
local and national codes which may include ANSI
Z223.1 (NFPA 54), NFPA 31, NFPA 211

If a flue gas silencer is used, the barometric damper

should be
installed downstream as there may be positive pressure in
the connector pipe upstream of the silencer.

Installation

Insert the barometric damper into the connector tee with the
control wheel in the vertical axis. Now adjust the barometric
damper carefully with an air level (fig. 2, axis of control wheel
horizontal, frame and control wheel vertical). Now fasten the
barometric damper by tightening the clamping screw (fig. 1).

Refer to manufacturer’s instruction for the required draft for
the appliance

. If the barometric damper is placed within 3 feet of

the appliance outlet, the typical draft setting would be between

-0.02”-0.08” wc.

Not following these instructions may prevent the barometric
damper from operating properly. This may disrupt the
combustion process of the appliance.

Start-Up (functional test)

After installing and setting the ba rometric draught regulator
verify the blade moves easily on the bearings. To do this, pull
the control wheel down manually and let it go to verify that
the blade swings back into position.

After setting the draught

the draft setting

If the draught regulator is installed properly and set per
appliance manufacturers requirements, it will run
flawlessly increasing efficiency and reducing standby
losses in firing systems.

Setting the Nominal Value (required draft)

The default setting for the KW Barometric Draft Regulator is the
highest setting. The required draft for the fireplace is set by
turning the control wheel (fig. 3). The measure "a" in inches

corresponds to the draft in inches WC. After setting the control

wheel, it should be locked in position. Turn the locking nut
clockwise to unlock the control wheel (fig. 1).

Maintenance

The KW Barometric Dampers require virtually no maintenance.
Check on a regular basis to ensure dust does not accumulate
on the bearing. If necessary (before the heating period begins),
the bearings can be lubricated with a

Do not lubricate or grease the bearings excessively since
this only increases the build-up of sediments.
