Maintenance - RBI SPECTRUM Series Installation & Operation Manual

Avoid placing the thermostat in areas that will not
provide an accurate measurement of the room
temperature. Locating the thermostat behind a door, in
an alcove, close to a source of thermal radiation or in a
drafty area will cause poor or sporadic heating.
For a thermostat that employs an adjustable heat
anticipator, adjust the anticipator to match the current
measured in the thermostat circuit. An increased
anticipator setting may be necessary if the unit cycles
frequently. If the room temperature over-shoots the
thermostat setting, reduce the anticipator setting.
Operating Control
The preferred control setting for potable hot water is
130˚F, 54˚C. The operating control should be set to the
lowest setting that will satisfy the consumer's needs.
WARNING: Setting the thermostat or operating
control too high can result in scalding resulting
in severe personal injury!
High Limit (Aquastat)
The high limit is located in the top control area of the
boiler/water heater. A remote capillary bulb is run to a
well on the outlet side of the supply header.
The water heater high limit should be set a minimum of
20°F, 11°C higher than the operating control. Refer to
the HOT WATER SUPPLY section for the proper supply
water temperature.
Flow Switch
A fl ow switch is provided in the water outlet piping to
prevent the boiler/water heater from firing without
adequate water fl ow through the heat exchanger.

MAINTENANCE

WARNING: Disconnect electrical power and close
the manual gas shut off valve before performing
maintenance or severe personal injury may
result!
WARNING: Improper installation, adjustment,
alteration, service or maintenance can cause
property damage, personal injury, exposure to
hazardous materials or loss of life. Installation and
