Manually opening vent damper

In event of vent damper failure:

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.
1.  Move damper service switch to

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 actua-

tor. Boiler will fire. Verify that damper service switch is in Hold Damper

Open position (Figure ).

.

Replace actua-

tor immediately. If vent damper is left in open position, boiler will not

operate at published efficiencies.

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 actua-

tor immediately. If vent damper is left in open position, boiler will not

operate at published efficiencies.

Before troubleshooting

1.  Have a voltmeter that can check 10 VAC,  VAC,

and a continuity tester.

.  Check for 10 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.

 Burner  access  panel  must  be  in  posi-

tion  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  ex-

cept  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 opera-

tion.

 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.
