TROUBLESHOOTING

These instructions are primarily intended for the use of qualified personnel specifically trained and experienced in the installation of this type of heating equipment and related system components. Installation and service per- sonnel may be required by some states to be licensed. Persons not qualified shall not attempt to install this equipment nor attempt repairs according to these instructions.

PROBLEM

1)When room thermostat is turned on, boiler does not operate.

CAUSES

1)No power to the boiler.

2)Defective room thermostat or discon- nected wire in thermostat circuit.

3)Defective transformer.

4)Defective pump relay.

5)Defective pump.

SOLUTIONS

1)Check circuit breakers, disconnect switch. Make sure power is on.

2)Check continuity on thermostat and wiring circuit. Replace thermostat, or repair wiring connections.

3)Check secondary voltage. If no 24V, replace transformer.

4)Check relay coil or contacts. Replace as required.

5)Replace pump.

2)When room thermostat is calling for heat, pump is on, but burners will not turn on.

1)For standing pilot models, pilot burner not lighted.

2)If pilot burner will not stay lighted, thermocouple or gas valve may be defective.

3)Gas knob in "Pilot" position. 4)For automatic ignition models,

gas valve knob is in "OFF" position.

5)Vent switch is open.

6)Roll-out switch is open.

7)High limit is open.

8)Fast Response Temperature Sensor probe is defective.

9)Fast Response Temperature sensor board is defective.

1)Light pilot burner. (Follow lighting instructions on rating plate.)

2)Check thermocouple MV generation. If less than 25MV (open circuit), re- place thermocouple. If between 25- 35 MV, replace gas valve.

3)Turn knob to "ON" position. 4)Turn gas knob to "ON". If ignition

module locks out, reset by interrupt- ing power to boiler.

5)Check for blockage of venting system or disconnected vent piping. After problem is corrected push button to reset, or replace single-use type vent

switch.

6)Check for blockage of flue or sooted heat exchanger. After problem is corrected push button to reset or re- place single use type roll-out switch. 7)Setting may be too low. Check water flow and adjust setting to obtain 20-

30°F temperature rise.

8)Red LED on circuit board will be ON to indicate a loose sensor connection or a shorted sensor. Check terminal connectors or replace sensor as re- quired.

NOTE: Red LED will also be ON if sensor temperature exceeds 300°F or drops below - 20°F. It will turn OFF when sensor temperature returns to the proper range. Yellow LED will be ON if temperature exceeds 240°F. It will turn off when sensor temperature falls below 180°F. When either Red or Yel- low LED is ON, boiler will be shut down. 9)Check voltage across output and

common terminals. If no 24V is pres- ent, replace board.
