Operating instructions

I. Check pilot burner ame and main burner ames
through observation port.
1. Check pilot ame. Refer to Table 11 for appropriate
pilot detail.
2. Adjust thermostat to highest setting.
3. Check main burner ames. See Figure 52. Flame
should have clearly dened inner cones with no
yellow tipping. Orange-yellow streaks caused
by dust should not be confused with true yellow
tipping.
Yellow-tipping indicates lack of primary air.
Improper burner alignment on Main Burner Orice
will also affect primary air injection. Adjust primary
air as follows:
