[Troy Farmer]

Can you guys tell me what this is and why? also longevity?

Would have to see the spec on the furnace it is new to me have not seen this before. My guess would be to help atomize the fuel as they are after the orifice. Probably constructed out of high temp wire but my thinking would be not to great on longevity

Built in spark arrester.
I guess you looked up the model , and figure it must be a add on.

Make, Model, Age ??? is it an LP unit?

That SS mesh material is on my old style Mr. Heater

Goodman Model#GMH80704BXAC SN#0709086461 2007

[Bob Elliott]

Yeah we see Goodman all the time.
No screens

[Troy Farmer]

I just spoke with my HVAC company he said "when you find out let me know"
he reiterated that why would anyone buy Goodman??

[Bob Elliott]

Seems to be the most popular model right now.
Just spent twenty minutes looking for your answer??????

I find it quite often, always in brand new homes. Never found an HVAC tech who could tell me what it is, or why, but it apparently burns away after a couple of years.

I believe it is intended to reduce Nitrous Oxide emmisions.

A quote from the linked article:

"Flame Inserts
A simple means to reduce flame temperature is to insert a foreign object, such as a solid rod or porous screen, into a blue flame and allow the object to radiate red hot. As part of the heat liberated is transferred by radiation, the flame temperature is reduced and hence the NOx emissions are reduced. The inserts could be made of refractory metals or ceramics."

I think Ralph may be onto something. That is a low Nitrous Oxide emission model according to Goodman.

You are correct

[Greg Veal]

Have you determined if these 'Flame Inserts' are offered/or per Manuf. Specs. or even allowed by Manuf.
I have two (2) Goodman NG Upflow furnaces (1-80%+ and 1-93%+) and have checked my Install./Serv. literature and have found nothing about these options. I'm guessing these won't match up to well engineering specs. I'll be interested to see what some of you find.

I don't believe it is an "option" since out here they come "pre-installed" by the manufacturer, which I guess is why none of the HVAC techs here know what they do. Their speciality is not in determining what everything does, just in installing it and repairing it. Apparently there is no problem with them eventually burning away.

why would anyone want to reduce nitrous oxide emissions????...personally I believe the world would be a much happier place if we had more nitrous oxide.....just my opinion.....jim
