PROCEDURE 5—CHECK OUT PROCEDURE AND ADJUSTMENTS
A. Verify Proper Sequence of Operation
The sequence can be followed via the diagnostic indicator lamps on the Integrated Boiler Control (IBC) in Fig. 21 and Table 9. This is the normal
sequence of operation. A more detailed sequence of operation containing potential faults can be found in the service hints section.
NOTE:
DO NOT use stop leak compounds. Leaks in threaded connections in the aluminum boiler sections must be repaired immediately.
Aluminum threads will not seal themselves.
B. Inspect Venting and Air Intake System
Operate the boiler and verify that all vent/air intake connections are gastight and watertight. Repair any leaks immediately.
C. Inspect Condensate Drain
Verify that all connections are watertight, and that condensate flows freely. Repair any leaks immediately.
D. Inspect System Piping
Verify that all connections are watertight. Repair any leaks immediately.
E. Test Ignition System Safety Shutoff Device
1. Turn off manual gas valve.
2. Set thermostat to call for heat.
3. Boiler begins normal sequence of operation.
4. After approximately 40 sec (pre-purge and igniter warm-up period), lamp D illuminates, indicating gas valve is powered.
5. After 6 sec, gas valve closes, lamp D goes out as integrated boiler control senses that flame is not present.
6. To restart system, follow operating instructions under

The following steps and diagram indicate the location of the connection points required to measure the manifold pressure.
The manifold pressure may be measured using a U-tube manometer or a differential pressure gauge (Magnehelic). The diagram shows the
connection of both measuring devices, but only one is required. (See Fig. 22.)
