water heater vent connector question

0 votes
When they replaced our chimney liner  and re-connected the water heater flue they came up out it the water heater 4 inches then over laterally 21 inches then down 14 inches to a slight rise to connect with the furnance flue then the chimney. Is this ok? Probably not the best but the height of the water heater was the problem.

Hi Ronlary,

smiley I'm not sure if I can follow your water heater's vent connector as far as up and down sections go, however, when you look at the entire assembly, there should be no part of it between the WH draft hood, furnace connector joint, and the chimney flue that has a negative slope.

There must be at least(!) a 1/4" rise per each linear foot of the run towards the chimney, the vent connector can never run down.

Let me know if you have more questions, just click "comment" below.
