I wouldn't put this in the wall of shame. Other than the unsleeved oil line, these old Aero's worked fine. Bock's were the same. They can make more hot water than a family can use.
A draft hood (or gap as you put it) serves a completely different purpose than a barometric. According to ASHRAE a draft hood isolates the appliance from the flue allowing combustion to take place without venting action. Since it disconnects the appliance, draft and air through the burner is completely uncontrolled. Draft hoods are designed for a specific set of conditions, which are; a vent of not more than 5 ft in height with 1 or 2 elbows. How often do those conditions get met in the field???
A barometric or draft regulator on the other hand allows for a consistent amount of air through the burner that does not change with changing conditions. Those of us who test for CO find draft hoods spilling quite often, either with higher than normal or lower than normal flue draft pressure. They are not safe under all conditions! A draft regulator is the only way to fix them. A spill switch added to the bottom of a double swing barometric will shut down the burner if the flue gets blocked.
I work on quite a few oil burners but have only seen 2 oil fired water heaters. Most of them got changed to electric it seems.
up here in CT i have worked on so many to oil fired water heaters the pain in the butt part is to clean them when there is no room for your brush
I cleaned 2 today, we have tons of em' up here in Patriots country!
"I don't know why it be like it is, but it do"
hey, that's cool! you can stick a power burner on ANYTHING!!!!LOLOL!!
never seen one.....but we don't have much oil down here.
I'll admit I'm kinda new I've only been an HVAC tech for 5 years, while I've worked on a lot of oil burners (only a couple oil water heaters though) and always have a barometric on oil burners. But never never even heard of one on a natural gas natural draft water heater. Would it help on that has a vent that should work well but doesn't, for example one 90 elbow and say 3 ft horizontal then into an flex aluminum chimney liner, say 2 story house?
might not have been code when it was installed in my area its grandfatherd untill you replace the line tank or valves
that we do
so if you have a gas water heater and you have a long flue run take off the natural draft hood and put on a barometric damper would be best i i thought that was so wind would not come down and blow out your pilot
