gas insert vibration

[lati_cz]

I just purchased and installed Empire DVL33IN73N, I followed instructions and did not have any problems installing. When I turn fireplace on, the burner vibrates and the glass get foggy. The vibration lasts several seconds and slowly goes away and the glass gets clear. It burns normally afterwords.
I called manufacturer, they suggested there's not enough air coming in - I checked intake duct it's clear and there are no bends. Any ideas whoa could cause the vibrations?
Thank you Michal

The fogging of the glass is common with gas burning units. The glass is cold & when the moisture in the gas is released by the combustion process, it'll adhere to the glass just like the moisture from a hot shower does to your bathroom mirror.
The vibration is NOT normal. Is the unit sitting securely in place? Can you rock it at all with your hands? It may be that it's not stationary enough until the exhaust liner expands from the heat & pushes the back of the unit down slightly...Just a guess here...

The unit sits cecurely. Only burner vibrates/rattles, not the whole unit.

Hmm. I think I'd shut it down, let it cool & get in there to see what's loose. Maybe something got moved/ loosened druing shipment, or something was not adequately secured during assembly...

their burners a full of some kind of ceramic balls, it may not be anything you can fix.
but a little noise during start up of pilots or burners isn't atypical. if it only lasts a few seconds is it really that annoying?

I was surprised by those vibrations, so I called manufacturer. They told me they never heard of it..... It really rattles!
