Generally, the furnace must be at least 90+ efficiency to be able to use PVC pipe. In addition, high efficiency gas furnaces require a condensation pump, to pump excess moisture out of the furnace. If yours has always been venting up a vent pipe, then NO, you can't use PVC pipe.

Hope this helps you.

    Look at the furnace. If the outlet coming from it that exits the combustion gases is made of metal, no you cant. If you can use pvc only if the outlet is made of pvc also. thanks and let me know.

Steve realize plenum needs to cool before shut down but even after cold still does not stop.


Ok - let's back up a little bit.. Do you have a forced hot air furnace? Does it run either oil or natural gas (or liquid propane)? Do you have a chimney or power vent?

Cleaning gas furnance flue


Pull the hose off to the pressure switch, and measure the pressure while in a call for heat with a manometer... check the pressure switch rating & compare. Make sure you don't have any down drafts...a high wind cap might be needed. Also make sure the chimney termination is 2 foot above any pitch that is within 10 feet.

I have a American Standard furnace Freedom 80 Mod# AUD080C936H3 and am looking for a manal or can you tell me how the exauhst is done. Can I use PVC


Hello, The only time pvc is allowed is if the Furnace is 90% or greater in effiecency, the combustion gases are cooler due to the fact that two heat exvhangers are used. One pipe will be you air intake and the other the exhaust and they can be routed through the roof or sidewall. If the Furnace is 80% then you must use double wall vent pipe and have it connected to either a liner in a chimney or routed through a roof but pvc can not be used.

In September 2010, we had a York yp9c120d20mp12c propane furnace installed in our home. Last we we began to notice an odor (slight) when the furnace came on, especially whe the furnace was on high volume....


DON'T SLEEP THERE with that furnace on. You're probably getting carbon monoxide poisoning.

Call your propane service provider and they may send out a tech who's more competent than the contractor's tech.

When the hot water heater is running water leaks from the chimney. the pipe from the heater to the chimney is dry upon removal. about 3 gals. of water leaks from the chimney with two showers.


If I understand correctly, your Bock gas water heater vent is causing water to leak down into chimney.
This is a very serious concern

Water leaking from water heater flue indicates improper venting.
The hot air gasses from water heater combustion contain water vapor, but the gas should vent out of house before condensate forms on pipes.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#flue

The problem might be caused by a power vented furnace that pushes vent air from furnace down into flue pipe for water heater. As a result, the water heater doesn't vent properly.
There could also be a clog.
Light a match under water heater draft hood and see if smoke from match travels instantly upward.

There are two major concerns.
1) If vent is not working, it means that odorless CO gas is entering home instead of venting outdoors.
CO carbon monoxide is deadly poison.
http://en.wikipedia.org/wiki/CO_poisoning
This is a very serious concern
You can buy CO detector after vent is repaired.

2) Water condensate will eventually rust away vent pipes because of acidic content of the combustion vapor. It can be expensive to replace pipes, and pipes with holes pose risk of CO poisoning.

My suggestion is call a qualified plumber ASAP and explain what you observe.
Plumber will want to inspect the vent pipes, and may want to extend water heater vent pipe up further inside chimney so furnace is not pushing air back into water heater vent.
Plumber may also find blockage somewhere in the vent stack or chimney.
Also post on a professional water heater forum like the Tank to double check anything the plumber says to you. These are the pros.

Does drip pan need to cover entire furnace or just coil. I got both answers for repair men.


When you say drip pan are you refering to a pan located under unit in case drain plugs ? If this is what you are talking about and you have a furnace that is 90% efficient or more which will be vented with pvc, it needs to be under the whole furnace as condensate water also comes from furnace when operating and if this drain plugs you will also have water leaking down from furnace. If it is a 80% furnace which will be vented into a chimney then pan needs to be just under a/c

I also deal with soot everywhere. I have propane. We do have a chimney that we vent when using. Still soot.


Soot is a sign of too much gas and not enough air. Have your propane supplier make proper addjustments.

Heat not coming on carrier gas pack code 31


code 31 indicates pressure switch did not close or reopened during the heat cycle....1st thing to check is the inducer motor,,this is a small motor that turns a small blower wheel that draws the exhaust gases through the furnace and blows them into the vent pipe....1st locate the inducer assembly,,most easily identified by the small plastic fan blade that cools the inducer motor as it runs..1st turn off tstat and turn off furnace power switch..then turn on furnace switch,then set tstat to heat,set the temp above room temp by 5 degrees...remove the furnace front cover,locate the inducer motor,,if it isnt turning,but is warm or hot after a minute or so,likely the inducer motor is bad..if it isnt turning and isnt warm after 1 minute,then likely the main control board is bad,,not turning the inducer motor when it should,,,,,if the inducer motor is running,,then the pressure switch isnt closing,, could be a bad pressure switch but more likely there is a problem with the venting...some possible problems that would cause the pressure switch not to close in an 80% eff furnace [metal vent pipe] are: [1] a blockage in the vent pipe,base of chimney,dead bird at the furnace where vent connects to furnace or down inside the inducer assy,accessed by removing vent pipe from furnace....if all clear the chimney could be blocked up inside,,is the draft good when vent is removed from base of chimney?..if furnace is a 90%+ type [pvc plastic vent pipe],,then check the intake pipe at the furnace by removing it where it attaches to top of furnace..is the intake clogged with anything?..then check the intake and exhaust pipes outside for blockages,,including ice/frost/snow at the exhaust pipe outlet..

Goodman Heater Blower Not Coming ON


I am experiencing similar issues..the blower you hear is the vent blower probably..mine does the same..it vents the unburnt gas out of the vent pipe thru the roof. you should be able to run the fan manually from the thermostat to at least check and see of the blower works atl..at least it will let you know if the blower motor is ok..I have had to replace the control board once and I think it is the culprit again..mine is sooooo erratic.
