11.2. Remove and clean the burner.
11.2.1. Remove the front cross brace and radiation shield from heater.

to expose the emitter and use a high pressure air hose to blow the ports clean. If this does not clean the holes, remove
the four (4) screws holding the emitter to its mounting ring and remove the emitter so that it can be cleaned both
inside and out with a wire brush and then blown out with a high pressure air hose.
11.4. Inspect the pilot burner and remove any foreign material with a brush or an air hose.
