SYSTEM TEST PROCEDURE
1. With the power re-established, block the chimney or vent pipe down stream of
the switch.
2. Adjust the thermostat to call for heat.
3. Once the heating system has started the blocked vent switch should shut down
the burner with 10 minutes or sooner.
4. Once the system has cooled, the blocked vent switch can manually be reset.
5. This procedure should be tested a second time.
6. After testing the blocked vent switch the chimney should be cleared of
obstruction and the heating system tested on a long run cycle.
7. If the block vent switch shuts down the system check to ensure there is enough
draft in the chimney and venting pipes.
