Ascent EK1T smells like raw diesel

Budgie

A clarification and update: We have called the installer four times to come and fix this. We've had several regular service appointments. Each time they come to fix this, they say they can't find anything. We have sent two additional emails which have been ignored!

Our two year old Ascent smells like raw diesel when the chimney is cold. The smell is coming from the air shutter. I believe it's set at the factory setting- I'm assuming the mark on the yellow label of the air band is the percentage. Ours is about where the mark is on the attached screenshot from the manual. Our chimney liner is 5" which is recommended. What could be causing this smell? Could it be the nozzle? If the nozzle size is correct, are there are other issues with the nozzle that could cause this?

EK hangs out on this forum so someone from their will probably post. Have you had the equipment serviced?

I hope you have had it serviced at least once since installation. If you have, what has your service provider suggested? Since the smell is from the air shutter the first thing I would do is check the condition of the burner nozzle and the oil pump seal.

This isn't DIY. Call your EK service provider. Today.

Like the fine gentlemen stated, like all heating equipment annual service and a tune up are needed to keep the equipment running safely and efficiently. That being said, Theres an air box cover designed to keep burner noise to a minimum and this chamber is usually piped to the exterior of the home to use outside air for combustion. This would be for efficiency. If this is the case, you should not have any air exchange into the basement or room in which the equipment is installed.

My recommendation would be to run the equipment with the air box cover in place as it was designed, hopefully the fresh air inlet is installed and call your service provider for an annual tune up and cleaning

@Roger from EK sometimes posts here. He's been very helpful to us.

@Budgie , where are you located?

Roger

Thank you for your posts. I saw that @Robertw was already responding so I only checked back now. It sounds like back drafting, so the system should be professionally serviced and inspected and likely have outside air connected and isolated with the air box. As Rob indicated, @Budgie , please call us if you are having issues contacting your installing and servicing contractor as we can help. (908) 735-2066.
