Never start up the gas heater section if the air-handling unit
is stopped, otherwise the hazard of local overheating of the
air-handling unit will occur, which can damage some components
(e.g. drop eliminator).
Gas Heater Section Start-Up
The gas heater is a special gas device which is characterized by a
special activation procedure (commissioning). After completing the
air-handling unit installation, it is necessary to place a separate order
for the gas burner activation with the gas heater manufacturer or
their representative. In addition to the gas burner adjustment, the
interconnection of safety thermostats and the control circuits of
the gas burner and air-handling unit (fans) must be checked during
the gas heater commissioning. A commissioning report, which also
includes settings of the gas heater temperatures and the results of
testing of emergency and safety components, must be drawn up upon
putting the gas heater into operation.
Separate documentation from the combustion chamber manufacturer
is delivered with this section.
