8.2 Unitary Heater Requirements

CTHN unitary heaters are typically shipped as a burner package, fan assembly and a tube and accessory package. The tube and accessory packages contain enough tube, reflector and hanging parts for one unitary CTHN heater. Elbows, u-tubes, controls, and any other parts must be purchased separately.

Table 5: Unitary Heater Design Requirements

See Page 14, Figure 13 for a general overview of a CTHN unitary heater. CTHN unitary heaters are controlled by thermostat.

Table 5 summarizes the design requirements for a CTHN unitary heater.
