Flanged Immersion Heaters for Liquids and Gases - Hazardous Location

All Bucan flanged immersion heaters incorporate a conservative design approach, use premium quality raw materials

and are made by a highly skilled staff. You can expect top performance and by following these instructions you will

benefit from many years of trouble-free service. Terminal box designations: Hazloc (CSA), NEMA 7 (UL).

Installation:

1. Only qualified personnel are to install industrial electric heating equipment and must meet all national and local

codes.

2. Nameplate data show the applicable CSA/UL Hazardous Location marking and the power connections voltage, phase

and wattage. Check this information against your specifications. Catalogue suffix is "X".

3. This heater also meets the requirements for Class 4 (CSA designation), NEMA 4 (UL designation).

4. You must allow adequate space for thermal expansion of the heating elements.

5. Liquid heaters must be fully immersed when the heater is energized.

a. In the event that your system generates sludge, mount the heater above the sludge level.

b. In the event that scale or other matter may build up on the element surface, clean as required.

6. Gas heaters must have a positive and adequate gas flow over the elements when the heater is energized.

7. Flange mating surface must be clean and free of burrs and surface damage to prevent leaking.

8. Your heater may have a built-in thermostat; this control can be either a pilot duty device or under certain load conditions

be directly connected to carry the full load at the rated voltage.

Operation:

1. Before heater energization, ensure liquid heaters are fully immersed and gas heaters have the required flow rate.

2. Heater sheath materials have maximum recommended operating temperatures; do not exceed the temperatures

shown in Table 1.

3. Sheath material selection depends on the application; check Table 1 for sheath material recommendations.

4. The terminal box also meets the Class 4, NEMA 4 enclosure specifications.

Maintenance:

1. Solutions may create scale and/or sludge build-up on the sheath; frequently inspect and clean as required.

2. Inspect and tighten the electrical connections as required.

3. Look for contamination inside terminal enclosure and seal properly to prevent potential leakage.
