SYSTEM CHECK-OUT PROCEDURE
1. Push the reset on the spillage switch. Light the appliance burner in accordance
with manufacturer's instructions. Operate the appliance to determine that the
appliance will operate continuously.
2. Adjust thermostat so the appliance burner is shut off. Allow system to
cool down, then remove the vent pipe connection near the appliance.
3. Block the appliance vent outlet with a noncombustible material.
4. Adjust thermostat control to call for heat. Allow approximately 2 minutes
for the system flue gases to back up and the gas burner to shut off.
5. Push the reset on the spillage switches, then relight appliance and
perform Steps 3 & 4 again.
6. Re-connect vent pipe connection and cycle system 2 to 3 times to ensure
continuous operation.
NOTE: Shutdown of appliance burner should not be more than 10 minutes.
