System Control Check OUT Procedures

1.Adjust the thermostat to call for heat and observe the power venting system for proper operation sequence (Repeat if necessary).

a.Thermostat calls for heat.

b.Relay is energized and venter motor starts.

c.Pressure switch closes and burner starts.

d.Thermostat is satisfied, the burner stops.

e.This starts the post purge cycle.

2.While system is operating disconnect power to the venter motor. This should open the pressure switch contacts and stop burner operation.

TROUBLE SHOOTING HINTS

1.Main burner does not fire when thermostat calls for heat with venter operating.

a.Check pressure switch adjustment.

b.Check wiring connections between pressure switch and burner. c. Check pressure switch for conti-nuity across terminals, during venter operation.

2.Venter does not activate when thermostat calls for heat.

a.Check wiring.

b.Check relay for proper operation.

3.Flue gas odor.

a.Check system draft.

b.Check for negative pressure in building.

c.Check post purge time.

MAINTENANCE

1.Motor: Inspect motor once a year, the motor should rotate freely.

2.Wheel: Inspect venter wheel annually to clear any soot, ash or coating which inhibits either rotation or air flow. Remove all foreign material before operating.

3.Vent System: Inspect all vent pipe connections annually for looseness and for evidence of flue gas leakage. Seal or tighten pipe connections if necessary.
