Product Overview

Monitron – Compact, easy to install for new or “standby” installations
Monitron combines the availability and dependability of electricity with the
comfort and performance of conventional hydronic heating using baseboard,
radiant or cast-iron radiators.
Monitron as a replacement unit: Works with virtually any existing
hot water hydronic radiation system. Although rated in kilowatts, it is
also clearly identified by BTU output.
Monitron as a standby unit: Particularly suitable for commercial
and industrial facilities, or office buildings which can’t risk down-time
with their existing heating equipment. If oil or gas is temporarily unavail-
able, the owner easily switches the heating system to the electric boiler.
Monitron as a primary heating unit offers:
• The convenience of electricity and the comfort of hydronics.
• No chimney required.
• Competitive pricing with electric baseboard systems.
• Simple zoning by zone valves.
Monitron by Slant/Fin is the electronic-age boiler designed to save
energy for new or existing heating systems.
America’s Best - Built Electric Boiler
• One piece cast-iron heat exchanger.
• Built in air eliminator.
• Internal baffles improve heat transfer.

NORMAL OPERATIONS
When the thermostat calls for heat, the circulator turns on and the first
electric heater bank is energized. At preset 30-second intervals, the other
heater banks automatically energize. The circulator continues operating
until the room thermostat is satisfied. A flow switch supplied by Slant/Fin
or others is required. It prevents the elements from being energized
unless the circulator is operating. This avoids element burnout.
* All models except EH-8 and EH-10
OPTIONAL MILD-WEATHER OPERATION
Mild-weather energy savings are made possible through the use of
circuit breakers on the breaker panel. This permits the owner to man-
ually switch off one or more of the elements. Then, when just a mod-
erate amount of heat is needed, all the elements are not energized,
cycling is reduced, and overheating is diminished. This energy-saving
feature is standard on Monitron models EH-12-S through EH-40-S.
