Can I connect this to my old vent hole at the chimney or should I seal the old hole and make a new one?

For the Rheem 8.4 GPM Natural Gas Mid Efficiency Indoor Tankless Gas Water Heater
Asked by: Gggggggggggg
The tankless water heater your mentioned should be using the 3" x 5" stainless steel concentric venting for the entire venting run, from where it meets the top of the water heater all the way to where it exits the building with either the horizontal or vertical termination kit.

how far is a water heater terminal vent be from a window. My water heater is outside

The gas company came and said it has to be 3 feet away. Is that right
Asked by: Wallawalla1
In the US we require the termination to be at least 12" from a window or door that may be opened. In Canada the minimum clearance is 36". Your local code may require a greater clearance.

If i vent the heater with a 90 degree elbow directly into a brick chiminey do i need anything other than the 90 degree elbow for optimal efficency?

The chiminey was the way the old water heater was vented and is also the way a oil burner / baseboard heating system is vented.
Asked by: John
If you are looking to put the 3x5 venting through the existing venting you should be fine. if you are looking to attach the 3x5 TO the existing venting, you will run into problems. For a better understanding on the venting and any further technical questions about this, please contact our support line at 866-720-2076

Rated 4 out of 5 by from made to work with the rheem water heater Good instructions - easy assembly - works well - happy with this vent pipe.

Rated 5 out of 5 by from Perfect for the job I didn't do the install myself. However this part seemed to go without a hitch. The installer popped a hole through the sill and caulked it off. We were done. Seems to be good quality. From what I've heard<read> from other installs, an absolute must!

Rated 5 out of 5 by from works like a charm Our water heater was not heating because it wasn't vented properly. We installed this piece and now the water is nice and warm like it needs to be. Since we installed this part, the water heater has not shut down once. Before we did it, the water heater would shut down 3 and 4 times during a shwer! If you are having vent problesm with your tankless water heater, use this!
