There’s a vent hose that comes off the battery box. Mane sure that the connection putty where the hose goes trough the plastic battery box and where the hose hooks up to the exterior vent assembly is pliable, complete and sealing. If hose has hose clamps make sure they are tight. Check the vent to make sure it’s clear.
All easy enough to do on our 21 at least.
