So i bought a house a couple years ago and there is this 9 foot tall mantle with beveled mirrors and carnival glass tiles surrounded in tiger oak. Yeah...amazing... it has this BEAUTIFUL brass(i think) insert that is gas fired. the chimney is one of those old fashioned ones that is enourmous in the basement and narrow at the top. though it is sectioned off inside at the base(assuming all the way up as well). i stuck my head in there recently because i had to replace the exhaust venting for my furnace. anyways the insert has its own flu, just a rod you pull and it opens a flap to vent. here are the pics of the fireplace The mantle extends to about 1' from the celing(the celings are 10') the pillars continue on up, i just did not take a pic of it because i have a bunch of stuff up there and was lazy lol the whole things needs a good cleaning but this is the area that concerns me, is there something that sits on top of those ceramic burners? the adjuster underneath takes a square ish key(which i do not have) to adjust the flame, near as i can tell. this is the rod that opens the flu. if anyone knows anything about this insert please share your knowledge. I would really love to light this thing. the gas company has leak tested all the pipes and connections and it looks good.
