Tiny gas burner in tiny fireplace with big unlined chimney: Bad idea or OK?

[joann5]

My latest idea for installing gas-flame ambience into my tiny fireplaces is as follows:

Use a small burner (12" single pipe burner pan unit) with appropriate safety pilot and fake coals and vermiculite.
I figure this wouldn't put out any more heat or water than a stove burner (??)

My chimney is unlined brick (flue interior dimensions 14" x 6"). How bad would putting something like a stove burner under an unlined flue? And running it only for a few hours at a time a few days a week a few months a year?

This is neither massive amounts of heat in the flue nor massive amounts of water vapor. Still bad? or OK?

I would say to ask the manufacture what they reccomend.

Thanks, I'll do that.

Code allows for up to 3 times the size but the unit may preform poorly...ergo contact the maker of that unit to see what they say.
Good luck.

Don't see how that's any different from folks who put gas logs in their masonry FPs. Done around here a lot including in older FPs w/ unlined chims. Never heard of any problems unless the install is not done correctly, or the chimney is not sound to begin with (eg. cracked through).

Good luck.

Peace,
