Hello,
First time poster here and am not sure if this is the right place so if not please move my post to the correct forum.
My question is this: can I install a vent hood over my stove if the pipe that I am going to use also exhausts the gases from the water heater? Or am I asking for a fire to break out? The house was made in 40 and there is a large(2′) that originally exhausted the gases from the stove and the water heater.
I just want the oils from cooking to go up and out and not on the walls where I have to tsp/simple green them a lot.
Thank you,
Mike

Could you explain the "large 2' " that originally exhausted the "gases" from the stove and water heater. That is not usual.
Sure, in a case where there is a chimney that had a flue for a wood stove-there might have been a water heater run in that same chimney (but in a different flue)...........but 1940 wouldn't necessarily be the right vintage.
We lived in a farmhouse that had a common chimney (can't remember if there were 2 flues or not) and through that ran from the oil heater in the basement and it also had an opening in the chimney for a wood stove in the LR as well as an opening in the kitchen that had a wood cookstove.. Not sure of the vintage of the house-might have been a late 30's or 40's.
But the easy answer now would be no-too much chance of the carbon monoxide from the water heater entering the kitchen.
Are there separate flues if this is a masonry chimney?
Perhaps a picture and we can figure a couple alternatives.
I have never seen a 2-foot-wide metal flue. Even a 2-foot-wide (on the inside) brick chimney would be unusual -- a more typical dimension is 8 inches or so.
It may be that what you have is two separate flues in a common stack. This would be more usual for a house of that era.
In any event, I have trouble believing that it would be "code" to have the water heater and range hood feeding the same flue. When the fan was turned on it would blow out the flame in the water heater, which is not good.
If there are separate flues internally it MIGHT be OK, but a 73-year-old metal flue is suspect in any event and at the very least needs to be inspected before you do anything.
Is the underfloor heater still connected to this conglomeration?
Maybe it is multiple flues in one common stack like you suggest. The underfloor heat was disconnected years ago-thankfully. Here is what it looks like in the attic. If it is multiple pipes then I should be ok in the fire danger area right? When I have this installed-I won't be doing it-I will have to have the pipe looked at like you suggest.
