Air Shutter adjustment for Flame Guard® (L.P.-30T only)

Important: On initial startup, condensation is normal. If unit is condensating, wait until it has stopped condensating before inspecting burner flames for proper operation. With the water heater on and the burner lit, inspect the burner flames through the viewport and compare them to the drawings in figure

18.A properly operating burner should produce a soft blue flame. Blue tips with yellow inner cones are satisfactory. The tips of the flame may have a slight yellow tint. The flame should not be all yellow or have a sharp blue-orange color. If the flames are not satisfactory then it may be necessary to adjust the air shutter. If you lack the necessary skills to perform the adjustment properly you should not proceed, but get help from a qualified service technician.

1.Remove the manifold assembly using the instructions on page 21.

2.Remove the two screws securing the burner to the manifold assembly, then separate the burner from the manifold assembly (see figure 29).

3.While holding the burner, loosen the air shutter set screw, and rotate the air shutter to adjust air flow to burner (See figure 30). Rotating the shutter to allow more air to the burner sharpens the flame, while restricting the airflow softens the flame. Once adjusted, tighten the set screw.

4.Using the instructions on page 23 replace the manifold door assembly.

5.Verify proper operation of the water heater. If further adjustments are needed repeat process beginning with step #1 above.
