. Plug damper harness receptacle into damper harness plug. Bypassing (jumpering) vent damper will cause flue products such as carbon monoxide to escape into the house. This will cause severe personal injury or death. After boiler has operated once, if either end of the harness is disconnected, the system safety shutdown will occur. The boiler will not operate until harness is reconnected. Effikal damper — Damper hold open switch must be in“Automatic Operation” position for system to operate properly. Part Number 550-110-032/0607 1 EG-30 thru 75 Series 4 and PEG-30 thru 65 Series 4 Checkout procedure 1. See pages 1 -18 for “Lighting Instructions”. . Raise room thermostat to call for heat. Damper actuator will slowly open damper. . When damper is fully open, main gas valve will open and main burners will ignite. Damper must be fully open before main burners light. If damper does not fully open, flue products will escape into house, causing severe personal injury or death. . Lower thermostat setting. Main burner flames will go out, then damper will close. . Repeat steps 1 through several times to verify operation. . Return thermostat to normal setting. Room thermostat anticipator settings Water without tankless heater — 0.40 amps Water with tankless heater — 0.20 amps Steam — Select based on gas valve and damper. See table below. 1 Part Number 550-110-032/0607 Standing Pilot Boilers — Control Supplement Lighting instructions — Robertshaw 7200 Part Number 550-110-032/0607 1 EG-30 thru 75 Series 4 and PEG-30 thru 65 Series 4 Lighting instructions — Honeywell VR8200/VR8300 Natural gas boilers only 1 Part Number 550-110-032/0607 Standing Pilot Boilers — Control Supplement Lighting instructions — Honeywell VR8200/VR8300 Propane boilers only Part Number 550-110-032/0607 1 EG-30 thru 75 Series 4 and PEG-30 thru 65 Series 4 Lighting instructions — Robertshaw 7000ERHC Part Number 550-110-032/0607 Standing Pilot Boilers — Control Supplement Troubleshooting Burner access panel must be in position during boiler operation to prevent momentary flame rollout on ignition of main flame. Severe personal injury or substantial property damage will result. Never jumper (bypass) any device except for momentary testing as outlined in Troubleshooting Charts. Substantial property damage and/or severe personal injury could occur. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.See vent damper manufacturer’s instructions packed with vent damper for additional information. Failure to comply could result in severe personal injury, death or substantial property damage. Before troubleshooting 1. Have a voltmeter that can check 1 0 VAC, VAC, and a continuity tester. . Check for 1 0 VAC (minimum 10 to maximum 1 ) to boiler. . Be sure pilot is lit. See “Lighting instructions” on pages 1 -18 for details. . Make sure thermostat is calling for heat and contacts (including appropriate zone controls) are closed. Check for VAC between thermostat wire nuts and ground. In event of vent damper failure: Effikal vent damper If troubleshooting chart recommends replacing actuator and actuator is not immediately available, damper blade can be fixed in an open position to allow boiler operation. Manually turning blade can cause actuator damage. Follow these instructions only in case of no heat or damper actuator malfunction. 1. Move damper service switch to Hold Damper Open position.Apply call for heat to boiler. Damper blade should then rotate to open position and boiler will fire. . If step 1 does not open damper, manually rotate damper blade to open position using wrench or pliers on flat shaft between damper and actuator. Boiler will fire.Verify that damper service switch is in Hold Damper Open position (Figure ). . Do not leave vent damper permanently in this position. Replace actuator immediately. If vent damper is left in open position, boiler will not operate at published efficiencies. Johnson Controls vent damper If troubleshooting chart recommends replacing actuator and actuator is not immediately available, damper blade can be fixed in an open position to allow boiler operation. Follow these instructions only in case of no heat or damper actuator malfunction. See Figure . 1. Turn off power to boiler. Failure to turn off power to boiler can result in severe personal injury, death or substantial property damage. . Refer to vent damper manufacturer’s instructions for procedure to fix vent damper in open position. . Turn on power to boiler. . Using wrench or pliers on flat shaft section, manually rotate damper blade until green light turns on. Boiler will fire (Figure ). . Do not leave vent damper permanently in this position. Replace actuator immediately. If vent damper is left in open position, boiler will not operate at published efficiencies.
