Hi guys looking for a bit of advice if anyone has experience on these. It's a powder curing oven with an natural gas Ecoflam burner on it. Was wondering does anyone know how you go about setting the air/gas ratio as this is a direct fired unit with an extract fan which causes more of a pull on the air through air damper of burner and when I open air damper CO is excessive. Any help would be much appreciated.
Cheers
