Operating Instructions and Owner’s Manual
Enerco | Heatstar ER2STG Tube Series Heater
Vent Adapter
Used to attach the heat
exchanger tubing to vent pipe.
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.
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 14 on page 16).
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.
Burner Housing
Must always be
installed horizontally.
Tube and Reflector Hanger
Install immediately after first
coupling.
Turbulator
Enerco Group, Inc. normally ships Ener-Radiant heaters with
turbulators assembled into appropriate tubes.
Tube and Reflector Hanger
Suspend system from these hangers.
Minimum two (2) required per tube.
Reflectors
Alternate overlap as shown
on overview. Length of
reflector and amount of
overlap is indicated.
10' 2=1/2"
ALUMINIZED
Heat Exchange Tubes
Supplied in 10 ft. lengths.
Tube Coupling Assembly
Coupling should be oriented with
slide bar on top, and all couplings
should “point” in the same direction.
Assemble the heater components as shown in Figures 2a, 2b, 2c, 2d, 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
