Burnham Series 2B manual Instructions to PUT the Boiler in Operation, Yellow LED Flame Codes

e.Reconnect pilot tubing and check pipe and fittings from meter to combination Gas

Valve for leaks using soap solution or other approved method.

2.Electronic Ignition Models (Suffix I):

a.Turn "ON" electric switch serving boiler.

b.Open Manual Shut-off Valve upstream of Combination Gas Valve.

c.Loosen or remove Inlet Pressure Tap Plug in Combination Gas Valve and when purging is complete, tighten or replace plug. See Figure 19.

d.Check pipe and fittings from meter to

Combination Gas Valve using soap solution or other approved methods.

CAUTION

e.Test gas piping and connections between Combination Gas Valve and manifold, orifices, and pilot piping for leaks after boiler is operating. Use soap solution or other approved method.

3. INSTRUCTIONS TO PUT THE BOILER IN OPERATION.

A.See Figure 20 for electronic ignition (EI). Electronic Ignition Modules with LED indicators. Table 5 cross-references the ignition module terminal designations to the ignition terminal numbers in the wiring ladder diagrams. The yellow

LED indicates the status of the flame, see Table 6.

The green LED indicates the status of the system, see Table 7. See Figure 21 for LED locations. See Figure 28 for Troubleshooting Guide.
