I have a 30 gal. Electric H/W heat in my kitchen that I want to remove. I want to install a gas water heater in the utility room between the gas furnace and gas dryer,and plan to vent it via a 45 deg. T throught the furnace flue. There isnt much room to raise it off the concrete floor because of the large chamber over the furnace. My qustions are: 1. Do I need to elevate it? 2. Is an intake vent nescesary? 3. Can the exhaust vent to the furance flue?

First, I am not a plumber. The home I bought had the gas water heater installed with the vent joining the gas furnace flue. We had a carbon monoxide problem and determined that the water heater could not vent properly when the forced air furnace was venting, therefore the water heater exhaust overflowed and could not go up the vent pipe. I dicussed it with my plumber at work (restaurant business) and eventually installed an in-line fan above the water heater before it gets to the T. I also changed the angle of the T so that the flow is smoother. The fan kicks on when the fan of the furnace comes on, problem solved. Be careful of this as it seemed to be the only solution.

Robert, Thanks for telling me about that. I thought it would be more of a venturi effect like a carburator. Do you need an input vent?
