Does a power vent water heater condensate?

Condensation, due to its acidic characteristics, is something to avoid in power vent water heaters, and most of the time, is the result of a piping configuration and environmental conditions. Most typical installations of gas water heater do not require any special methods for condensate disposal.

Can a power vent water heater Backdraft?

Because of their unique construction, power vent water heaters are virtually impossible to backdraft. That means the risk for carbon monoxide problems caused by your water heater is significantly lower with a power vent water heater in place.

How do you troubleshoot a power vent water heater?

Try to check your gas supply pressure and manifold pressure. The gas control may be set too low. Take a look at your thermostat to see if the water temperature setting of your heater is not set too low. Try adjusting it to see if that solves the problem.

How do I stop my water heater from Backdrafting?

The simplest way to prevent backdrafting is to provide a source of replacement air (also called combustion air) for your furnace, water heater and fireplace to replace the air that flows up the chimney with the exhaust fumes (Fig. C).

How far can you run a direct vent water heater?

This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents. PVC is fine. As Jason mentioned, plastic (PVC or ABS) is ok to use as a venting material on powervented hot water heaters.

What are power vent water heaters?

A power vent water heater is vented horizontally and vents exhaust through a horizontal pipe that leads out your home. An added fan/blower pushes the exhaust gases through this pipe. Extra power is required to power the blower, and this power source is separate from powering your water heater.

What is the difference between a direct vent and power vent water heater?

The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent. A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe.

Why is my hot water heater not venting properly?

The main reasons for backdrafting at the water heater are the poor vent installation and obstructions found in the vent pipe. This problem affects mainly the atmospheric gas type water heaters that use natural convection to remove the combustion products, known as exhaust gases.

How far can you vent a power vent water heater?

Power-vented natural gas water heaters use an electric fan or blower to push or pull combustion gases to the outdoors. This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents. PVC is fine.

How do you reset a power vent water heater?

Manual reset is accomplished by first, turning off power to the water heater for 10 seconds.
Restore the power to the water heater.
Within 10 seconds of restoring power, press the two temperature adjust buttons simultaneously until the left (green) “Vacation” LED begins to blink (approx.

How do you stop Backdraft?

Try opening a window near the fireplace to increase airflow into the home before opening the fireplace door. The area will be exposed to more air, allowing for less to be immediately taken through the chimney. Also, consider using a fan or turning on exhaust fans to troubleshoot this problem.

Can a water heater be vented out a sidewall?

Venting. All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion. The vents go directly through an outside wall, and can also bring in combustion air to the gas burner.

Where does condensation go from a power vent heater?

Power Vent and Power Direct Vent heaters are equipped with the condensate drain, so the water vapor from the exhaust gases will roll down the PVC vent pipe and through the drain port out. The recommendation is to get a condensate drain kit for convenient draining, and metal drain pans to protect the room where the heater is installed.

What are the clearance requirements for direct venting?

In a table below we provide a complete list of required clearance distances between the air intake or combustion gas exhaust vents for direct vented heating appliances. The exhaust vent terminal shall be located at least 3-feet above any forced air inlet located within 10-feet.

How does a heating appliance vent work in a building?

The heating appliance vents directly out through a building side wall, powered by natural draft provided by the heating equipment, typically using a single wall metal flue or chimney or a B-vent.

How does direct exhaust venting work in a boiler?

Direct exhaust venting draws combustion air from the utility room or boiler room around the heating appliance and vents appliance exhaust out through a building sidewall or through the roof using an approved or listed B-vent, metal chimney, or similar materials.

What causes condensation in a power vent water heater?

Condensation, due to its acidic characteristics, is something to avoid in power vent water heaters, and most of the time is the result of a piping configuration and environmental conditions.

How does a power vent water heater work?

Instead, both systems typically expel exhaust through a pipe that runs outside through an exterior wall. The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent.

How does direct venting affect a heating appliance?

In the direct vented system, flue gases are not cooled in a chimney. Heat that is typically lost in the chimney can be extracted in the heating appliance, dropping the gross stack temperature to 300°F-350°F. This raises the steady-state efficiency.

What’s the difference between a vent and Direct vent water heater?
