7. SYSTEMS INCORPORATING 90 O ELBOWS AND 180 O ELBOWS
The STSp-WP 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 FLUE VENTING in
SECTION 11 (page 14).
Both the 90 o and 180 o elbows are shipped as
a kit, with one coupler kit and two end plate
hangers to close off the reflector ends
around the elbow(s). Reflectors must be
secured with four screws to each of the end
plate hangers, SEE FIGURE 3, (page 7) and
FIGURE 6 (page 8).
On Models STSp-WP 200, 175 a minimum of 30´ of straight
radiant tube and on Models STSp-WP 155, 130 and 110, a
minimum of 20´ of straight radiant tube must be connected
to the burner before any turns are made. On Models STSp-
WP 80, and 60, a minimum of 10´ of straight radiant tube
must be connected to burner before any turns are made.
