Suck or blow, you're in effect creating a furnace unless you do something about the fire.
If the space was properly designed there should already be ample air entering/exiting the space to support diesel ops. No need to add more. Your local fire department probably has a smoke generator and since they might be the one's putting out the fire (unless you're anchored/moored offshore). You might be able to rent it... Seems to me the safer option is to have automatic or manual dampers that will shutdown the air into the space (in attempt to choke the fire) and have an automatic extinguishing system that, if not enough capacity to completely fill the engineroom, can at least be directed at most likely sources of fire. That will keep you out and safe so you can do the cleanup and be ready for the next fire...

But at this time the powered vent is not actually vented to the outside, but to a large locker that is open to the saloon. So if sucking smoke it would dump the smoke into the locker that spans the deckhouse from side to side at the forward wall of the saloon. It does have two outside doors, one at each end of this long locker that can be easily opened, but the middle of the locker opens without a door into the saloon. I plan to continue the air path to vent continuously to the outside "someday". The primary thought was to have a strong source of fresh air to enable me to get a breath while I am in the engine room (ER). The power vent enters the ER about two feet from the entrance so I could stick my head there, breath more-or-less fresh air while purging the ER, and be able to see whatever is on fire. As further constructions happen I could reverse the air flow. In fact, I did discuss with Jan the wisdom of using a smoke bomb in the ER to test the entire concept sometime soon. What do you think would make a good smoke generator that wouldn't stink up the boat too much? Norm S/V Bandersnatch Lying Julington Creek 30 07.695N 081 38.484W > > > REPLY > Norm a question here.
