Can you vent a gas hot water heater out the side of the house?
All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion. Atmospherically venting gas water heaters is the most common type of venting option used. The vents go directly through an outside wall, and can also bring in combustion air to the gas burner.
How much does it cost to replace a water heater vent?

Do I need a chimney liner for gas water heater?
For optimal use and safety, a liner is needed when installing a new heating system, furnace, boiler, or water heater. Local codes and the International Fuel Gas Code require proper venting and chimney liners for flue gasses to be vented into the outdoor atmosphere.
What happens if you don’t vent a gas water heater?
That is, the average water heater still burns fuel—be it natural gas, oil, or propane—and that fuel burning releases byproducts like carbon monoxide. Without proper ventilation of the noxious gases created by combustion, modern water heating would be a dangerous proposition.
Can you vent a hot water heater into a chimney?
When venting a gas water heater to a chimney, be aware that holes in the chimney can prevent a good draw on the water heater, causing downdrafts and presenting the risk of carbon monoxide poisoning. To avert this problem, you can vent the water heater to the largest hole in the chimney and cap the remaining holes.
How do you vent a water heater through a chimney?
- Install an increaser in the largest hole in the chimney.
- Install smoke caps in the smaller holes and seal them with furnace cement.
- Install an increaser on the flue base on the water heater.
- Install the 90-degree elbows on the two increasers, and then rotate the elbows so that they’re aligned with one another.

Can you power vent into chimney?
But longer heat exchangers produce draft resistance and they lower the temperature of the exhaust gases relative to atmospheric temperature. To enable proper venting, an inducer fan is built into the system. The fan, however, does not exert positive pressure into the flue pipe.
Can you vent into chimney?
Two or more appliances could vent into an exterior chimney, but design conditions must be appropriate along with appliance fuel input. Additionally, one of the appliances must have a draft diverter (natural draft system). Some single appliances can vent into interior chimneys.
