Caution
Check combustion room insulation after burner removal.
After removing the burner the combustion room insulation must be
checked for the correct position and increased wear. None of the
panels should have slipped and caused large gaps. If in doubt, re­
place the insulation.
1. Check the combustion room insulation to make sure it is in the cor­
rect position; if the insulation is torn, tipped forward or has large
gaps, it must be replaced.
