I just replaced a 14 year water heater with a new one. The vent on
the old is a 6" 90 degree pipe with an interior heavy metal pipe.
This pipe was fastened directly to the old tank top and vented through
the wall. The new tank has a 4 leg cone-shaped metal support which I
cannot get the old vent to fit properly. The tank is very close to an
exterior wall. The new tank is a GE Rheem and the guy at Home Depot
said that in a month this model will be replaced with one with a
motorized forced air vent, but that does not do me any good right now.
The owners manual on the water tank does not describe the proper
venting configuration. Taking the old pipe to a metal worker to have
it resized is my only option? Is there a web site that
shows/describes the safe and proper way to vent a gas water heater?
I think you have a problem.
The new heater has a "draft hood" or "draft diverter" and is
intended for venting into a chimney (or tall flue pipe).
It will not work properly merely venting out a side wall.
shows some pics.
Lots of GOOGLE hits:
Thanks to all that responded. I cut the vent tube to fit the new
heater, secured it with sheet metal screws and installed a CO detector
nearby. I tested the input draft area with a burning stick of
incense to see that the smoke enters the vent tube.
Might I suggest that you get another CO unit..
and put it where you are normally, and install it at the correct height, and
location...if this units in the basement, a CO detector wont do you much
good down there.
