BURNER FLAME

All orificing and pressure setting was done at the factory and, with proper supply pressure, will provide a safe, efficient source of heat. However, if any questions about manifold pressure, have a qualified serviceman check with a manometer, Natural Gas will be 5”, L.P. Gas will be 10” w.c. A proper burner flame (See Figure 7) will produce a reddish-orange flow on the surface of the ceramic burner plaques. If the burner flame has blue streamers or the flame is floating off the surface of the plaques, turn heater off and call a qualified service person. Do not operate heater if all plaques are not glowing. NOTE: There will be approximately ¼” space on the sides and top of the burner that will not glow.
