IOTA DLS-55

[Howard O. Truitt]

In my 1986 PT 40 the compartment that held the old battery boilers is
vented on the top, the side wall next to the engine and the rear wall
next to the batteries.
There was a 20 year accumalation of dust, dirt and oily grime in the
compartment. Do I need to seal off all ventilation outlets before
installing the two IOTA'S or do they need some ventilation.
