General Information
Description
The gas heat section consists of a drum-and-tube heat exchanger, burner, gas train components,
and a control panel for electrical connections. It is an integral part of the entire air-handling system.
An access door is provided for service and maintenance of the burner and gas train components.
The gas heat section must be in a blow-thru position downstream from the supply fan.
Downstream sections must be separated by a blank access section and discharge temperatures
must be controlled so as not to exceed the temperature limits of components in the downstream
sections.
Depending on the heater size, an external vestibule that extends the width of the gas heat section
may be used to house the burner and gas train components (see
Figure 2
). The external vestibule,
if required, ships attached to the gas heat section. Some heaters have gas train components in an
internal vestibule (see
Figure 3
). Refer to
Table 2
for vestibule locations.
