The STS-p Series radiant tube heater can be
installed in configurations as illustrated in
FIGURE 2. (below) with a maximum of two
90
o or one 180 o elbow per heater. The use of
radiant elbows reduces the total maximum
vent allowable. See SECTION 10 (PAGE

Both the 90 o and 180 o elbows are shipped as a
kit with one coupler and two end plate hangers
to close off the reflector ends each side of the
elbow (s). The Reflectors must be secured
with four screws to each of the end plate
hangers, See FIG 3 (PAGE 7) and FIG: 6
(PAGE 8).

minimum of 30’ of straight radiant
tube must be connected to the burner
before any elbow. On Models 155,130
and 110, a minimum of 20’ of straight
