If a third-party actuator is used, a connection kit is available for some popular options.
Operationally, the actuator must control the valve in the same manner, and be able to
provide the same ignition point. Either 4-20mA control or an adjustable shaft is required.
If the air is controlled by VFD, the motor will operate between 60Hz at high fire and 15Hz at
low fire. 15Hz is the minimum frequency that the motor should be run at. In certain
applications, such as those operating under pressure, it may be necessary to increase the
low fire frequency to satisfy the air pressure switch.
To operate the burner under vacuum may require the air pressure switch to be connected as
a differential. Proper burner operation may also require the use of a characterized valve or
regulator capable of sensing a differential pressure, instead of the standard NFPA or ratio
regulated manifolds. For burners intended to be fired into high suction, the combustion
blower may need to be fitted with a larger motor or replaced with a higher pressure blower.
In applications with vacuum, consult Hauck.
Operating the burner under positive chamber pressure may require the air pressure switch
to be reset to assure flow through the burner, or connected as a differential. Proper burner
operation may also require the use of a limiting adjustable orifice and metering orifice in
addition to the standard NFPA or ratio regulated manifolds. High chamber pressure may
require boost air or the specification of a different combustion blower. In applications with
positive pressure, consult Hauck.
Applications that have a 50 Hz supply voltage, should select the VFD option for the ability to
fire at the rated high-fire capacity. Applications with a 50 Hz supply voltage that do not use
a VFD will have a de-rated burner capacity and require different burner settings.
A manual air valve handle may be used to control the air flow to the burner. In a fuel-only
control application, the manual handle has the ability to be fixed, and may be the desired
method of air control.
2. Fuel
Manifolds
See additional literature instructions for the specific operation and setup for the fuel manifold
included on the package. If no fuel manifold was ordered, operate according to the codes
and requirements pertaining to the application.
3. Burner Control System
See additional literature instructions for the specific operation and setup for the control
system included on the package. If no control system was ordered, operate according to the
codes and requirements pertaining to the application.
NOTE
The use of a third-party actuator without a Hauck BCS may require
additional electronic components to be installed and wired by the
customer.
