Thanks, Shane. Good points you've added too!
I know that plexi and Lexan can be expensive if purchased new but but small, scrap pieces can often be found and then cut to size with a jigsaw.
About the "heater hot spots" that I failed to add - yes this is very important... another reason to get a safety guard. The rockwork can also interfere with filter intakes. Care must be taken in both of these instances.
Obviously, there is a lot of other info that could be included to, but then, it'd be a book rather than a beginner article.
Any other input is very welcome!!
BTW, my wife helped me with the grammar.
