Enerco ERXL-80 Manuale Utente

Enerco | enerRadiant® XL Series Heater

Operating Instructions and Owner’s Manual

•  When installed over hoists, minimum 

clearances to combustibles must be main-
tained from the uppermost point on the 
hoist.

 

Electrical:   The heater must be electrically grounded in 

accordance with the National Electrical Code, 
ANSI / NFPA-70 – latest revision. Wiring must 
conform to the most current National Electrical 
Code, local ordinances, and any special 
diagrams furnished.

 

Venting:   The venting must be installed in accordance 

with NFPA-54 / ANSI Z223.1 – latest revision, 
National Fuel Gas Code. Partial information 
with regard to this code is provided in 
(Section 5) of this installation manual with 
regard to size and configurations for venting 
arrangements.

•  Any portion of flue pipe passing through 

a combustible wall must be dual insulated 
or have an approved thimble. Refer to 
ANSI-Z223.1 – latest revision.

Locations:   Where there is the possibility of exposure to 

combustible airborne material or vapor, consult 
the local Fire Marshal, the fire insurance 
carrier or other authorities for approval of the 
proposed installation.

 

  Ener-Radiant ERXL 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 combus-

tibles, and safe distance from the 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 on page 15).

•  Provide access to burners for servicing, 

preferable on both sides, above and be-
hind the burner for removal.

•  Provide a minimum of 18 inches of clear-

ance 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 ?). 

Locate a support near all elbows.

 

  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.

 

DO  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 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.
