Hello
I realize this is an old post but had info to add you might want to know.
You can get your coleman focus 5 and 10 heaters repaired .
The coleman focus rebuildt burners are rebuilt on your burner tube assembly you provide from your coleman focus heater.
The rebuild is a 3 layer high temp stainless steel screen to be at least 5 times stronger than a factory burner bulb for crush test so it will take rough handling without falling apart.
Have most of the parts as well so just send an email and ask qestions for a reply.
