Venting a Hotwater Tank

[Anonymous]

I have to move a hotwater tank to a place in my basement that is 11′ from the nearest wall..There is no way to go straight up and the maximum rise possible from the top of the tank to the outside wall is 30″…Is there any other alternatives to getting a direct vent water tank or would they even work in a situation like this ?
Thanks !

The NFPA chimney guides make no mention of a connector offset 11 feet long with a rise of 3 feet for the total chimney affect except to point out that the connector is not in portion to the chimney rise. In other words, you need a direct vent kit for your natural vent water heater or you need a direct vented water heater.

The water heater would work whether you attach it to a chimney or not. Some crazy or ignorant rural installers do that. The combustion gas helps kill any insects in the basement and humidifies the building; but it is a practice that will violate insurance and safety codes that are intended to save your life.

I was pretty sure that I would have to go with a direct vent water heater. My present WH is not direct vent yet is still in great shape.You mentioned a conversion kit to modify my standard vent to a direct vent. Sounds like a money saver to me. Any particular brands to look for or places to find this item ?
Thanks for your help !

Look at electric water heaters instead of an illegal, unsafe natural gas unit.
You may be able to mount a blower on the vent to extend the length of convential venting, but I do not know the particulars.

In an 11 ft. run you need a 2 3/4″ rise on your flue pipe. after exiting the building you will need to run your flue pipe verticle a specified heigth (check your local codes). You will need to use an insulated flue pipe ie: B-Vent (again check your local codes).

Field is one manufacturer of power vent kits for gas appliances. See your local plumbing/heating supplier for the model you need. A local plumber may know what you need.
