Is a vent kit for a square 12 x 12 flue tile available?
By Tyler M. - Fireplace Specialist on November 5, 2012
Answer:While the top collarplate piece for this vent kit is rectangular in shape, it will indeed work for your 12" x 12" square flue.

We are trying to find a gas insert solution for our fireplace. It is complicated by the fact that we are on the bottom floor of a 5 story brownstone. Our chimney height is approximately 60 feet. Do you have a solution for this?
By Collin C. - NFI Master Hearth Professional on November 25, 2013
Answer:Unfortunately, we do not carry a vented insert that uses a venting system that can exceed a height of 40 feet. Any greater run would cause issue with the cooling of flue gases and operational issues. Your best options would be to use a vent free insert or if possible, use a conventional direct vent fireplace within the opening and terminate the vent horizontally.

I have a 6 inch thimble going though my wall of the hearth to an 8 inch flue. Will this kit work for me?
By Collin C. - NFI Master Hearth Professional on September 16, 2013
Answer:This vent kit is actually designed to vent a direct vent fireplace insert directly through a damper opening and into a fireplace flue from the bottom. It cannot be used to vent through a thimble.

Can I get this kit with a round chimney cap? I believe it is 10"-12" diameter. I need to order the insert, the vent kit, the surround and the bottom piece right away. However, my firebox opening is 4 3/4" higher than the hearth. Will the recommended "Empire Surround Bottom Cover - For SC336BL and S336BL Surrounds" fill the 5 3/4" gap under the insert and firebox? I really need the info on the chimney cap to complete the entire order.

What is the material of this vent piping? Stainless? What if you need extra footage for a tall chimney, do you sell extra vent pipe?
By Collin C. - NFI Master Hearth Professional on June 25, 2012
The liners contained in this vent kit are constructed of aluminum, as this is the standard material used for gas applications.
There is indeed a vent extension kit, which can be used to add extra height to the standard kit. This item can be seen here
The kit will contain the needed couplers and clamps to link the liners together and form a tight connection.

Can I pack unfaced fiberglass insulation around the two 3" pipes near the damper area to stop cold air from coming down the chimney?
By eFireplaceStore on December 5, 2014
Answer:You can and this is the recommended way to seal the fireplace from the cold air intrusion you are experiencing.

I am buying DV 35 in - 33 in. I have existing pipe with 1 outlet. Do I need a vent for outside fresh air also?
By Collin C. - NFI Master Hearth Professional on February 17, 2014
Answer:You can indeed use any existing 3 inch flex vent for the exhaust outlet on the insert. A short section of 3 inch flex must be routed to the first clay flue tile of the chimney for combustion air. The flex liner for intake air does not need to run all the way to the termination, however the area around the liners should be sealed with fiberglass insulation to prevent the unit from pulling air from the room and past the insert surround.
