Pilot and Burner Flame CAUTION Check pilot flame and burner flame periodically to ensure proper operation. 1-PilotFlame --Pilot flame must surround the end of flame sensor for proper operation of pilot safety circuit. See figure 7. PILOT FLAME (Side View) BURNER PILOT GAS LINE ELECTRODE (G20E & G20X) FIGURE 7 FLAME SENSOR 2-BurnerFlame--Start burner and allow to operate for a few minutes to establish normal burning conditions. Check burner flame by observation. Flame should be predominantly blue in color, strong in appearance and should rise directly from the burner ports in the heat exchanger. Check to see that flame is burning from all continuous ribbon ports and that flame does not impinge on the sides of the heat exchanger. See figure 8.
