Federal airtight 224 acl

[Catfish044]

Have a federal airtight 224 acl , question is when the bypass is engaged should it close Off completely the rear exhaust and everything run up threw cat ? Or is there supposed to be a slight gap or clearance on that bypass gate ? Thanks

I have only been around that model briefly. I'd put money on it needing sealed to force the exhaust completely through the cat.

Close it off completely, open the upper vent two rotations, then close the bottom vent all the way. Use the middle firebox vent to regulate the burn. I have the same stove.

I close the bypass completely , control the burn With the fire box vent , have the cat air open a few turns , my question is with the cook top removed and cat removed does the bypass gate seal off completely to push all exhaust threw cat, I’m getting pretty good cat temp , seems like it takes a while to get cat temp though ? I notice when I have the cook top off and cat removed that bypass gate didn’t seem to fit tight up against back flue area to seal it off completely ?

I don't have that stove but on mine the bypass seals tight. You stick a piece of paper between the bypass and the gasket and should be able to pull the paper out. Mine has a adjustment on it.

Yeah I figured , I have a good 1/4 gap on mine , looks like the bypass door itself is worn out
