Vent To Empty Garage Overnight


Recommended Posts

OK I'm bisque firing in a temp studio in a garage. As such the vent is not perm installed but floor mounted and the hose is running to the outside under a partially opened garage door. Since its cold out I want to just pull the hose in and shut the garage door and let it vent the heat directly in the garage so the room stays warm and will be easier to work in tomorrow morning at 6. Is there a hazard to the rest of the house doing this? The temp is passing 1100 now.

It's not good. I suppose it depends on how tightly sealed the garage is from the house, but the garage is going to fill up with fumes. If you left a car running in the garage would you be confident that the exhaust wouldn't get into the house? The other issue is that you're going to be pumping all the particulate matter from the kiln fumes into your garage. Ideally you need to set it up properly so that the fumes are vented outside.

yeah figured it wasn't worth the risk since I wasn't sure.

The vent is floor mounted and the hose does goes completely outside and extends several feet around the corner of the house. It just goes under the slightly raised garage door.

There's nothing unsafe about that is there?

Don't own the house and using garage temp so drilling a hole in brick wall to perm mount not possible.

Moving to perm studio in few months and will wall mount the vent then.

In my old studio I have always just left the vent running until I unload and figured it helped the cooling a bit. Since we do have some low 20 degree days coming up in this temporary garage I figured I'd pull the hose in at about 1500 when everything is burned off so I can shut the garage door and put the heater back on. 

 

Nothing wrong with that plan is there?

Assuming the vent hose is 4" maybe you can buy some 2x6 the same length of the garage door minus 4" , drop the door onto the 2x6 and stick the vent outside through the side. Then stuff something along the top to the door to close that off.

 

Or buy two pieces of 2x6 so you can place the hose somewhere in the middle.

 

Or buy a 2x6 the length of the door and use a circle cutter to cut a hole big enough to pop the hose through.

I don't know how often you fire but since your are moving I wouldn't invest a lot of money in a temporary fix.  If you do happen to have a board laying around that it about the width of the garage door you could cut a hole in it  and have the door rest on it.  Run your vent hose through the hole and tape around it.  Denice

I raise my garage door 4 inches for the vent duct and I put some old comforters that I duck taped together all down the rest of the garage opening. This keeps some of the radiant heat in the garage but lets out all the fumes and particles. I find it works well. In the summer I just leave the 4 inches open as I don't want the radiant heat.

My kiln is in the garage, and when bisquing I don't bother with opening a door since the roll-up door is not a snug fit. When glazing I roll the door up a few inches (enough for the cats to get under, but not the dog) and open the side door a bit to allow air flow. I'm in CA so I'm not as cold as some of you, but the other day it was quite cold but I wanted some studio time, so I turned the kiln on low and left the lid open long enough to take the chill off so I could get some work done.

I need to get my spare propane tank filled and drag out my sunflower heater!
