Why do I have water coming out of my furnace?

Why do I have water coming out of my furnace?

And of course, absorbing more heat takes more time. Enough time, in fact, for those gases to cool down and condense into water before it leaves the furnace. Normally, high-efficiency furnaces drain away condensation via a draining system. But if that water ends up on your floor, that’s a sign that there may be an issue with your furnace.

What does a condensate pump do in a gas furnace?

Some high-efficiency furnaces may use a condensate pump to push condensation toward the proper draining area. A condensate pump is a small white box connected to the PVC drain pipe and pumps water toward drain.

What does it mean when your furnace is leaking condensation?

A leaky humidifier is often misdiagnosed by confused homeowners as a leaking furnace. You’ll need a professional to inspect the humidifier to see what is causing the leak and fix the issue. Unlike conventional furnaces, condensing units are actually designed to produce condensation.

What to do when your gas is shut off?

If your gas is shut off, turn the gas shutoff valves on all gas appliances to the “off” position until the gas service is restored.

Are there unions in the National Fuel Gas code?

I think the National Fuel Gas Code allows unions in accessible locations, but some local codes only allow the union at the appliance. Go with what your inspector will accept.

What kind of Union do you need for a gas line?

Any union in a gas line must have a valve in front of it. Blue stuff might be Megaloc Teflon Thread Sealant. Companion flanges are code approved when dealing with two points of piping where you cannot gain access to the opposite end of piping. best pipe dope for gas is rectorseal yellow. i believe it is #5, softset.

Where does the water come from in a gas furnace?

The drains inside the furnace deliver the water to an internal condensate trap, and that trap attaches to external condensate pipe. The condensing type furnace has another feature that differentiates it from non-condensing furnaces, how it gets combustion air.

What happens to the heat exchanger in a gas furnace?

The secondary heat exchanger reclaims the latent heat of condensation, which occurs when the condensing flue gases containing water vapor change back to liquid water. This is called latent heat of condensation, in which latent or hidden heat is given off when the water vapor turns to water, but remarkably no change of temperature happens.
