Maintenance - RBI Spectrum series Installation And Operation Instructions Manual

Operating Control
Per DOE mandate, the operating control incorporates an automatic
means (thermal purge) of adjusting the boiler water temperature
for hot water heating. 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.
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 flow switch is provided in the water outlet piping to prevent the
boiler/water heater from firing without adequate water flow through
the heat exchanger.

MAINTENANCE

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

Servicing, inspection and adjustment must be done by
a trained technician in accordance with all applicable
local and national codes. Improper servicing or
adjustment can damage the boiler/water heater!
The ceramic combustion chamber contains crystalline
silica. Wear a tightly fitted dust mask when removing
the burners or heat exchanger to prevent inhalation
of airborn fibers. Crystalline silica fibers have been
identified as carcinogenic, or possibly carcinogenic
when inhaled.
The boiler/water heater should be cleaned and inspected once a
year and before each heating season. Make sure that the burners
and ignition components are free from dust, soot, dirt, corrosion
or other deposits that would impair the boiler' s performance. Refer
to page 24 for component identification.
Improper burner servicing can result in premature
burner failure voiding the warranty!
Burner Drawer & Burner Removal
1. Close the manual shutoff valves in the gas supply lines and turn
off electrical power to the boiler/water heater.
2. Disconnect the gas train from the gas supply piping at the ground
joint union.
3. Remove the flame roll-out shield.
4. Remove the two screws that attach the burner drawer to the
base panel, Figure 12.
5. Disconnect the electrical wires going to the gas valve and burner
drawer.
6. On intermittent pilot models disconnect the ignition cable from
