Our Blue Flame Natural Gas 30,000 BTU Stove Smokes the wall above it all the way to the ceiling and keeps the wall very hot, this is the second one we have tried, has anyone else had this problem?

It comes from the factor ready to use PROPANE, if you are using natural gas, then it needs to be re-jetted or orifices changed for the proper gas.

Hi Hilary. I'm Roger. There are several different kinds of smoke detectors that detect a fire in different ways and all look basically the same. My knowledge is a few years out of date now but I think the technology has stayed the same. There are some that look for the density of the air passing through them (Smoke). We had trouble with this type in large commercial buildings that had large quantities of dusty air passing over them when mounted in the ductwork. There are others that detect the high carbon content of the air produced in a fire. Others detect the higher than normal temperatures. And the last one I know of, detects ionization of the air. The first three above are self explanatory. Ionization of a flame is a little more complicated but just be aware of it. It applies when higher temperatures than it is set for are present. In general, all of these things rise to the highest point in the room. The ceilings above your stair wells is a good place for a detector. In the kitchen, on the ceiling above a door away from ovens and toasters may be a good location if your kitchen doesn't get really hot when you cook and bake. On the ceilings of the living, dining and bedrooms rooms. Look at the literature that came with your detectors or look it up on line. Most detectors use several of these technologies combined and always give recommendations for locating them. Consider the first three things above when choosing a location for the detector. And, of course, the detector may be set too sensitive for the area it is in and goes off under a condition that is normal in your home. Try switching it with another one in the house and that may help. It could be just plain too sensitive period and can't be used at all. Be aware of how air moves through your home under normal conditions and place them accordingly. In a fire, normal air flow is overcome by the heat pushing air much faster than normal and will quickly hit areas on a ceiling that might normally be a relatively dead spot. Good luck with this. I hope it has helped. Roger

Hayward pool heater smoke

Is it smoke? Could it be steam?
If so, condensation "Rain in the inside of your new heater". This is a real problem & needs to be checked out by a Certified Heater Technical service man. Preferrably, not the one who installed.

Does the vaporizer help fight against smoke and second hand smoke??

No, it only humidifies (puts moisture) in the room air. As a matter of fact. that much humidity, the cigarette smoke may stain the walls and ceiling.

Can the burner inlet air be adjusted on a coleman DFAA066BBTA oil fired furnace ? if so how do i set it ?

Sure can. To do it properly, you should perform a smoke test after each adjustment. This requires a special tool. This may be why noone has answered your question yet. There is a band on the left side of the burner that can be opened to allow more air in. The flame should be bright orange/yellow. And again, perform a smoke test after you adjust it.

I turned my propane fireplace on and it set my smoke alarm off. We have lived here for three years and never had this problem before. Please advise.

check to see if the flame is pure blue. if not you have incomplete combustion letting CO or CO2 into the room. The flame will look yellow if this is the case. An orange flame indicates dust and dirt around the burner assembly. If it is yellow, the should be 1-2 set screws on the back of the burner assembly that will let you adjust the primary air being mixed with the propane.Adjust until you get blue flame and tighten set screws.

We bought new Dimplex baseboard heaters when we re-did all of our rooms and the new heaters are leaving black marks (like smoke damage) on the wall above the heaters. Our walls are ruined

Stop burning candles! Yes, believe it or not the black is smoke from candles which is deposited there by/because of air flow. How did I know you burn candles? Been in the HVAC business a long time and that is the only thing I've ever seen cause it!

Smoke or vapor coming from new h400fdn hayward pool heater.

Not at all uncommon. New heaters have to glaze over the file tile in the burner chamber and will often smoke and smell during the first week or so of operation.

Using a mirror, check to see that your flames are about 4" proud of the burner tubes when running. As long as they are and the color is a nice blue with little to no yellow/orange color, the heater is fine.
