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.

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.

I have a new H400 Hayward poole heater. There is white smoke coming off the top. I thought it would stop after a few minutes however it has not stopped after 45 minutes. The heat transfer is good and it...


Are you sure there is nothing on top of the burners?
It is normal for the heater to burn some smoke because of residual oil on the exchangers, but you would think 45 minutes is plenty of time to burn it off? Try for a little while longer? Maybe it is not smoke? could be steam? Possible of condensation or small leak? What is your water flow like? Is pressure too high, is flow to high or to low? These may need to be checked by a service tech. Because this is a real problem when you get "Rain inside your heater" Possible improper installation?

My harley smokes


all engines do cold. its water vapor and or the hot exhaust, causing the air, to change dew point, (looks like steam)
on the white smoke smells like burned oil , it is, and is slow to dissipate like steam, (see moms tea pot , and steam fast dissipation?)

if it is oil , its most likely bad valve guides and seals, or both.
if a compression leak down test passes, its not rings, (mostly)

Burning smell when running car ? Oil or electrical ?


open the hood and observe the smoke(if any) electrical smell will show a yellowish color with a blue/green/red yellow flame and it moves fast..oil smoke and antifreeze smoke(vapor really) will sort of "steam" off from near the area its leaking from when hot.. brake smell and clutch smell are almost the same since both use like materials for friction..keep an eye on this for potential problems and may need to move the vehicle outside so if it goes up in flame the house wont/grarage whatever//

My mazda 626 has a strong potent smell coming from the exhaust


You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...
