Critical Considerations
Ener-Radiant XL is a suspended heater. Therefore, its stability, flexibility, and safety are very
important. Before starting installation, be sure the system can meet the following requirements.
•
Maintain specified clearances to combustibles, and safe distance from heat-sensitive
material, equipment and work stations.
•
Provide a suspension with vertical length of chain or swinging rod which has at least 2
inches of horizontal travel for each burner in a straight run. Be sure the suspension system
is sufficiently flexible to accommodate thermal expansion which occurs as the system
heats up (see Figure 5).
•
Provide access to burners for servicing, preferable on both sides, above and behind for
burner removal.
•
Provide a minimum of 18 inches of clearances between burners and building walls.
(Always observe minimum clearances to combustibles).
•
Be sure the heater has a downward pitch of one-half inch per 20 feet away from the burner.
•
Provide signs in storage areas to specify maximum stacking height to maintain required
clearances to combustibles.
•
Plan location supports (see Figure 2). Locate a support near all elbows.
Installation Procedure
Take maximum advantage of the building upper structure, beams, joist, 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)
•
Pressure test the gas line using high pressure (greater than 1/2 PSIG) without closing the
high pressure shut-off cocks. Failure to do so will result in damage to the burners.
•
Familiarize yourself with local and national 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 18).
•
Have slip joints where required between reflectors 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 within 12 inches of the bottom of the enclosure.
