In Reply to: CB EXCESS AIR posted by ROY REYES on December 03, 2008 at 09:41:02:
: I have two Cleaver Brooks CB200-200 with about 120% excess air, my customer requirements are 40% or below, the only way I could achieve this was with more gas and less air but by this time the flame was way too rich and sooting up.
: Any ideas on how to fix this? Maybe bad shelf gasket? or rear door gasket?
: any information will be greatly appreciated.
