Water Heater Venting


Recommended Posts

Hi Guys,

Any comments on the venting of this water heater would be appreciated.

Besides sharing a masonry chimney with a wood burning fireplace on the other side and questionable slope it seems a wye connector may be needed to vent it above the boiler. No evidence of back drafting but venting is newly installed.

Thanks again,

The wood burning fireplace venting through an adjacent flue has nothing to do with the venting in this flue. Ignore it.

That set up has several problems.

* Since this is a garage in a cold climate, the vent connectors should all be insulated, double-wall material.

* Either the vent connector before the water heater is oversized or the one after the water heater is undersized. A properly sized vent connector will step up in size where a second appliance joins it.

* Unless that's a really tall chimney, the horizontal portion of the vent connector is too long.

Personally, I think that there's no advantage to a wye vs a tee in this application. The gases are being *sucked* out not *pushed* out. Tees work fine.

Thanks Jim,

The fireplace and gas fired appliances both vent into a single clay lined flue. Two flues were noted at the chimney however, one is abandoned. Photo included below.

Thanks

Then it's wrong. You shouldn't have gas appliances venting into the same flue as a wood-burning appliance unless the equipment is designed that way.

By the way, they must never have built a fire in that fireplace. I've never seen a fireplace flue liner that clean.
