The furnace should have never been installed without combustion air in the first place, is it in the attic, basement, closet? The amount of combustion air depends on the btu's. you can run ,metal ducting to the space. propane is a heavy gas and needs to be installed carefully so gas cannot puddle and fill up a specific application if not installed properly.

This is no doubt due to failure of the "hot surface ignitor". This device lights the main burners for your furnace, and they fail a lot. I strongly recommend the replacement should be done by a technician.

Make sure fan relay is wired correctly (G) wire. Ensure the fan on therm is not on, it should be on Auto or off.

If your furnace is short cycling because it has to keep heating your home, the delay in the control board may be staying on to compensate for the exchangers getting hot. If it heats normally, then put your attention to your thermostat.

Set the heating system on aux heat only. Fan should not be on, if it does stay on after a heating cycle, see if the furnace is heating normally, and reaching temp as desired before the heat comes off. Then check the therm wiring, pull the face of the therm, disconnect green wire (fan) and try the heating again.

Propane turbo heater. After awhile why does it start to burn eyes and nose?


Hi Eric

It sounds like the heater is getting the air in the room so warm that it's making your eyes and nose hurt. That can be from dryness, from heat, or from combustion products.
Depending on the partucular model, you can try to:
  1. Turn the set temperature down.
  2. Turn the turbo fan to a lower setting.
  3. Turn the feed valve from your propane tank to a slower feed. At some point, you should be able to throttle the amount of fuel burning in a period of time to where the heat is more bearable.
  4. If you're smelling fuel, or overt burning petroleum smells, turn the unit off. This is a sign that things aren't burning right.
Last, but probably most important. If you are running a unit like this inside, make sure you have windows open. Please take me seriously here - installed propane furnaces have heat exchangers to pull in fresh air, heat it, and pass that air into your house. A propane heater burning inside your house is burning your inside oxygen and, depending on the flame quality, dumping Carbon Dioxide or, worse, Carbon Monoxide, into your house. You can end up dead pretty quickly, especially from Carbon Monoxide poisoning, and you'll likely be feeling fine right up to the time you pass out. These types of heaters are meant more for outside use, so please, if you absolutely feel you must run it inside, keep windows open and have a fan running. You're playing with your health

Good Luck!

My furnace isn't heating my house. I was wondering if this was because there is a vent from my cold air duct to the outside thus drawing to much cold air into the system. Should this vent be closed in...


If this vent is connected to the return air duct line back to your furnace I would close it off. The only reason that I can see for having a vent to the outside is if you need more combustion air supply.Thank you.

well lets start with the 2" pvc pipe. that is a combustion air intake it does not put air into the room, i hope. this is a 90% furnace and they should have installed it that way. there should be 2 pipes to the outside the other is combustion gases. the dust problem maybe caused by the air return pulling the air to that room. the bedroom normaly does not get the trafic that the rest of the condo does.so it would not have as much dust.

Colman mobile home gas furnace to use in my garage/shop


generally speaking a sealed combustion system is inherently more safe than a system that draws it's combustion air from it's ambient location. however, it cannot be considered 100% safe in a potentially hazardous location. The actual system that would be used in a "code compliant" installation would be a 100% outside air unit.
That being said, you can install this in a garage, the vent that you are referring to (if it is a standard mobile home system) is generally directly above the unit and usually no longer than about five feet. It also requires a listed and labeled termination "cap" If you install 90 degree angles or extend the vent too far you will have issues with condensation in the piping that will cause the pipe/ heat exchanger to fail prematurely.
If the system is a 90+ efficeint unit then the PVC venting is generally allowed to be about 30 feet long, with a 1/4 inch per foot pitch back to the unit for condensation, also the general mfg. instructions allow either 2- 90 degree or 4 45 degree fittings in the line. hope this helps

Honeywell furnace humidifier thermostat & other


sounds like to me you have a condensation pump attached to your hvac system. this can be used to pump water produced during the cooling of your house when in the a/c mode. if you have a typical bypass humidifier, you will have excess water running past the water panel and it must be sent to a drain of some kind. I would imagine the pump is being used to get your bypass water to the drain. another scenario may be that you have a 90% condensing furnace. if your exhaust pipe for the furnace is made out of pcv pipe, it is a condensing gas furnace. it will produce water when it is running. the water if from the combustion gases being condensed in the secondary heat exchanger. this is normal. some condensing gas furnaces will draw combustion air from inside the house and some will have a second pvc pipe that is used to pulll combustion air from the outside of the house. either way, it is not dehumidifying your house. the humidifier should be able to keep up if it is runnng properly. you should have water running out the bottom drain of the humidifier any time the fan on your furnace is running and the humidistat is calling for humidity. if this is not happening, it is not wired properly.

Heater flashes 3 times says it means combustion switch failed to close


Combustion switch is your vent safety.. Check your vents outside for blockage, sometimes the intake pipe will freeze or frost up not allowing the preassure switch(vent safety)to close. putting furnace into a lock out.. you can reset the furnace by turning the power on and off.. if there is no power switch just remove the bottom door and reinstall...
