Installation Procedure
Take maximum advantage of the building upper
structure, beams, joists, purlins, etc., from which to
suspend the heater. There is no unique sequence for
installation of the tubing. On-site observation will usually
reveal a logical sequence. Begin the installation at the
most critical dimension. This could save time. Watch for
swinging doors, overhead cranes, car lifts etc. Reflectors
and tubing can be installed as you move along. Carefully
adjust system pitch at each position to level the heater.
Pitch down one-half inch in 20 feet (away from burner).
DON'T Pressure test the gas line using high pressure (greater
than ½ PSIG) without closing the high-pressure shutoff
cocks. Failure to do so will result in damage to the
burners.
FIGURE 2: Ener-Radiant XL Overview
Assemble the heater components as shown in Figures 2A, 2B, 2C, 2D, 2E, 2F and 2G. Optional reflector configurations are shown in (Figure
1). Install appropriated suspension hardware, beam clamps, chain or rod at predetermined locations. Adjustment of chain length will provide
uniform pitch.
10' 2-1/2"
Turbulator Assembly
Enerco normally ships Ener-Radiant heaters with
turbulators assembled into appropriate tubes.
Where Field Changes Occur
Turbulator Sections and Adapter are available in
sections and must be assembled before installation
(See Figure 3 for details). The number of sections
required is indicated.
Burner Housing
Must always be
installed horizontally.
Reflectors
Alternate overlap as shown
on overview. Length of
reflector and amount of
overlap is indicated.
Enerco | enerRadiant® XL Series Heater
Familiarize yourself with local and national
DO
codes.
Develop a planned procedure which will conserve material
and labor on the job.
Check to see that all material and equipment is on the job
before starting installation.
Allow for thermal expansion of the hot tube.
Install the gas connector only as shown in instructions (see
Figure 14 on page 17).
Have slip joints where required between reflectors to keep
them from buckling or coming apart.
Provide 1 sq. inch of free air opening to each 1,000 BTU/hr.
of heater input (but not less than 100 sq. inches) in enclosed
spaces. One opening should be within 12 inches of the top
and one within 12 inches of the bottom of the enclosure.
