Question about Goodman GMS90703BXA Heater

1 Answer

Where does the Oxygen for combustion come from- Indoor or outdoor?

Is there a separate feeder tube that feeds oxygen from outside for combustion or does the speace heater take indoor oxygen for conbustion?

I live in an apartment in Buffalo and I think I got a Goodman natural gas heater with model number U-18L.

I've been having a little shortness of breath that is concerning me. I would appreciate your answer.

Where does the Oxygen for combustion come from- In - condensing_furnace_diagram.png

Gas heater normally get air for combustion from the outside as seen in this diagram.

Hope this helps...and hope you feel better soon!

Why does my gas fired AGA produce very sooty deposits on the outside wall with a fan assisted short flue


Soot indicates incomplete combustion. This can be dangerous because in addition to the soot, you are probably also getting carbon monoxide. Can you increase the amount of oxygen?

Is the monitor 422 heater considered a direct vent wall heater


Yes, the Monitor 422 heater is direct vent type.

You must install the supplied double-walled vent tube between the heater and outdoors. Failure to properly install the vent tube will quickly deplete oxygen from the space it is operating in. That is a potentially deadly situation.

The pipe is special. The inner pipe is for hot exhaust gasses to be sent outside and the outer walled pipe is for fresh combustion air to be brought into the heater. This set up is why the heater does not create drafts in the home.

Can anyone tell me why my direct vent fireplace flame looks like its in a wind storm. The pilot blows out as a rexult


Looks like too much yellow in the flame. That is normally caused by the mixing control on the gas feed tube being too closed. Trace the tube from the burner .....back toward the gas feed line....until you find the slip ring that controls the amount of oxygen that is mixed with the gas. Open is a small amount and light it. You should see a bit more blue color. If that does not work, continue to vary the adjustment until the flame burns correctly. The pilot should never blow out unless the outside air feed is too large. You can try blocking it a small amount to see if the smaller amount of outside air corrects the problem.

My rinai gas heater is not reallly lighting up though gas flow seems alright


Gas also requires oxygen to burn, perhaps there is an issue in an air feeder or mixing valve some where in your piping or if there is an inlet for air ensure that it is not obstructed. Using any combustion device in a confined space can be problematic for health reasons and the combustion process due to a finite oxygen supply. I hope this helps your investigation.

Idles rough and low intermittently. Stalls occaisionally. Error code P1137 pulled off of the computer. 2001 Alero, 2.4L Automatic trans


P1137 is HO2S Bank 1 Sensor 2 Lean Or Low Voltage. Oxygen sensor is reading a "lean condition". This code probably is stored from the rough and low idling. So it sounds like you maybe having other issues causing this P1137 code to come up. For lean conditions read this:
1. Vacuum leaks - check for failed or loose vacuum lines, leaking intake gaskets, intake air tubes loose or any other source of un-metered air leaks (leaks after the Mass Air Flow Sensor)
2. Restricted fuel filter or bent/pinched fuel system lines
3. Incorrect input from other sensors, such as the Mass Air Flow Sensor/cam or crank sensors, which may not always drop a separate code
4. Engine misfire ? Yes I know this one may seem weird. You might think that if there is a misfire then you will have all that unburned fuel and it should read rich; right? Well the O2 sensors read only oxygen content in the exhaust, so if you have all that unburned fuel from incomplete combustion then, you guessed it, you also have all that unburned oxygen. High O2 content in exhaust equals a lean reading!

What are the causes for NXo reading


A high NOx reading can be caused by any conditions that make the engine run lean. Vacuum leaks will dilute the fuel/air mixture with excess air leading to lean running. Lean mixtures lead to high combustion temperatures which produce NOx.

A malfunctioning EGR valve will not recirculate enough exhaust gas to keep combustion temperatures in check. The primary purpose of this valve is to lower NOx emissions are high RPM. It does this by delivering some low oxygen content gas back into the intake stream to dilute the incoming mixture. By decreasing the oxygen, combustion temps are lowered.

By the same logic, a misfire can cause high NOx. If the fuel/air mixture is not burned, excess oxygen in the exhaust (catalytic feed gas) will cause a dramatic decrease in catalytic converter efficiency in reducing NOx

Dose the buick park avenue use a map sensor or a mass air flow sensor. or are they the same thing


They are different types of sensors, but in your car the MAP (manifold absolute pressure) sensor, along with the BAROmetric sensor are used to estimate the required fuel flow through the throttle body injectors. These sensors measure pressures inside and outside the engine to estimate airflow. You do not have a MAF sensor. These are more common in later vehices with mulit-port fuel injection. A MAF sensor actually measures the airflow into the engine using a hot wire anemometer. You are correct in believing the sensors serve the same purpose, that is to calculate the fuel flow required for stoichiametric combustion. The oxygen sensor also feeds back to the computer to further refine the fuel charge by measuring oxygen in the combustion products. If excess oxygen is detected, the fuel charge is increased. This is known as closed-loop operation. Closed loop operation is not started until the engine is at operating temperature. If you have more questions, please let me know. I have pasted the location of the MAP sensor below. The sensor is mounted to the air cleaner, but it has a vacuum hose that leads to the throttle body, which is where the pressure must be measured.

PO174 HOW TO CLEAR THE CODE


P0174 is SYSTEM LEAN BANK 2. If you do not have any rough running or missfires. Check for any vacumm hoses that may be damaged or loose. Any code that is set on OBDII has to be cleared with code reader. If you have any rough running or mussfires, check fuel injectors for proper operation. If this helps, please rate.
