D. Prepare to check operation.

1. Obtain gas heating value (in Btu per cubic foot) from gas supplier.

2. Connect manometer to pressure tap on gas valve. See Figure 12.

3. For natural gas fired boiler, temporarily turn off all other gas-fired appliances.

E. Follow Operating Instructions to place boiler in operation. See Figure 17.

F. Sequence of Operation. See Figure 14. If boiler fails to operate properly, see Troubleshooting Tree on pages 17-18.

G. Check gas piping and connections between Gas Valve and Manifold, Orifices and Pilot Tubing. Use soap solution or other approved method. See Figure 13.

H. Check pilot burner flame. See Figure 15. Flame should be steady, medium hard blue enveloping 3/8 to ½ inch of sensing probe.

I.Check main burner flame. See Figure 16. Flame should

have clearly defined inner cone with no yellow tipping. Orange-yellow streaks should not be confused with true yellow tipping.
