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 14, Figure 13 or See Page 17, Figure 16 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 32, Figure 19 through Page 35, Figure 23 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.
