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.
