Basic Operation

WARNING

CAUTION

Service on this boiler should be undertaken only by trained and skilled personnel from a
qualified service agency.

Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the
electrical supply to the pump. Instead, shut off the gas supply at a location external to the
appliance.

Do not use this boiler if any part has been under water. Immediately call a qualified service
agency to inspect the boiler and to replace any part of the control system and any gas control
which has been under water.

A. General: This appliance is a sealed combustion, condensing water boiler and is equipped with

controls for proper operation. All controls must be maintained in proper working order. Contact a
qualified service agency to provide annual maintenance as specified in the Installation, Operation
and Maintenance Manual.

B. The following diagram shows the safety controls and device locations on the appliance. If any one of

these controls or devices are activated, contact a qualified service person immediately. Do not try to

correct the problem without contacting a qualified service person.

1. Primary Safety Control: The primary safety control monitors all limit controls and will prevent
the appliance from operating if a limit has been exceeded. This device also monitors blower
speed and temperature to assure safe operation of the appliance.

2. High Vent Temperature Limit: This device interrupts appliance operation if the vent
temperature exceeds the maximum allowable temperature of the vent material. The control
display module will display “HIGH STACK TEMPERATURE” if this device is activated.

3. High Temperature Limit: This device automatically interrupts boiler operation if the supply
water temperature exceeds 210°degrees Fahrenheit. The primary safety control will not allow
the unit to restart until the reset button is depressed on the display module. The control will
display ”OVERHEAT LIMIT OPEN” if the device is activated.

4. Flame Sensor: The flame sensor monitors the flame and communicates with the primary
safety control to interrupt the gas flow to the appliance if no flame is present. The primary
safety control will lock out if the flame sensor malfunctions producing a false flame signal.
The control will display “IGNITION ERROR, “ “FLAME FAILURE,” or “FALSE FLAME
DETECTED” if this device is activated.

5. Safety Relief Valve: This valve protects the boiler from excessive pressure. This device can
discharge a large amount of hot water and should be piped to discharge near the floor and
away from contact with people. The discharge should be piped near a floor drain if possible.

6. Gas Valve: This valve interrupts the gas flow if no power is present from the primary safety
control.

7. Condensate Float Switch: This device automatically interrupts boiler operation if there is a
blockage in the condensate drain system. The control display module will display “BLOCKED
CONDENSATE DRAIN” if the device is activated.
