wall furnace flame recirculation

I have an older double sided gas wall furnace. The local furnace guy wrote up a problem- my wall unit has flame recirculation - what does he mean and how to fix

Does he mean flame roll-out which could be caused by a blocked, damaged or incorrectly installed flue, does the heater have a fan?  could the heat exchanger be cracked ?   which would require replacement of heater

flame recirculation

That has got to be one of the poorest definitions of a problem I have heard?  Sounds like he really doesn't know.  Maybe its flame fibulation?  Or flame resonance?  Don't know what any of those mean either.  Obviously he didn't do a combusion test!

flame ?

What was your complaint that brought the repair guy to you? Flame rectification?

I have no idea what he meant - never heard of such a thing. I think maybe trying to get me to buy new unit.



the unit is pretty old but still works well - no sticky gas valve, no pilot problems, heat exchangers are fine - solid working unit, just old



I had a couple guys from a different furnace shop stop by and they started up unit and ran without incident. they never heard the term either.



i hope it is not an intermittent problem.....I am just trying to follow up in abundance of caution



FYI - it was part of an inspection

Call the company that supplies your gas    In a lot of areas they will check your heater free of charge,  and I always recommend a good CO detector in all rooms

Perhaps the inspector

meant that products of combustion were being "recirculated" back into the room. Was this a home inspector? What did he advise you to do? Did he leave the unit shut off?
