B. DIAGNOSTIC FLASH CODES

Flashing LED’s provide diagnostic information

WARNING: Only a trained, experienced service technician should perform troubleshooting. Turn off all electric power to the boiler before service

* Control Lockout

To reset the lockout condition: Turn down thermostat or turn power off at disconnect switch for at least 45 seconds, then restore power or set thermostat at desired setting.

Automatic reset: After one hour (1/2 hour for flame failure), control will automatically retry.

SAFETY CHECK

1.Checking for gas leaks:

Using soap solution, check for gas leaks from meter to gas valve including all pipes and fittings, gas valve con- nections, manifold and pilot burner gas line and its fittings. Use liquid soap solution for all gas testing. DO NOT use open flame.

2.High limit control (Aquastat) test:

Set room thermostat high enough for boiler water temper- ature to reach high limit setting. When this temperature is reached, the high limit switch should open. Pilot and main gas valve should close. Inducer starts 15 seconds post- purge period. POWER and TSTAT/CIRC LED’s will stay on.

3.Thermostat test:

Set thermostat setting to low enough to end call for heat. Pilot and main gas valve should close circulator off and inducer will start 15 seconds post-purge. POWER LIMIT and PRESS SWITCH LED’s will stay on during post- purge. After the post-purge period, POWER and LIMIT LED’s stay on.

4.Control safety shutdown test:

With main burners firing (all LED’s on) disconnect igni- tion/sensor cable from boiler control. Gas valve should shut off burners, FLAME LED starts flashing.

5.Pressure switch test:

With burners firing, remove plastic hoses from pressure switch or from aluminum tubing (see Figure 21), gas valve must shut off, PRESS SWITCH LED starts flashing.
