SECTION 5: HEATER DESCRIPTIONS
5.1 Unitary vs. Multiburner
CTHN-Series burners may be used for unitary
heaters or for multiburner systems.
Unitary heaters consist of a single burner, a single
run of radiant tubing and a single fan assembly. See
Page 17, Figure 15 or See Page 20, Figure 18 for
details.
Multiburner systems consist of more than one burner
and more than one run of radiant tubing. The runs of
radiant tubing are connected together by manifold
tubing. The manifold tubing connects to a single
pump that exhausts the flue gases outdoors. See
Page 36, Figure 21 through Page 39, Figure 25 for
common multiburner system layouts.
Since this manual addresses installation of both
unitary heaters and multiburner systems, pay
close attention to section and figure titles to
verify relevance to unitary heaters or multiburner
systems.
