Can I get more than a 30 degree offset if I use all of the adjustments?
By Collin C. - NFI Master Hearth Professional on September 20, 2013
Answer:No. 30 degrees will be the maximum attainable offset and is the maximum allowable by code. Any greater offset will cause creosote buildup and possible drafting issues with the unit.

How much rise does this 30 degree elbow get me?
By Brennan W. on April 6, 2015
Answer:This elbow set, by itself, will give you 16 3/8" of rise.

Coming off of the firebox, my pipe will not go through the wall at 90 degrees and may not line up with the vertical old pipe (to be removed) perfectly. Therefore, where the pipe goes through, the soffit would have to be altered. Would the adjustable 30 degree offset help with a vertical alignment issue? (For example: If the pipe is a little off to the side where the old vertical pipe was).
By Collin C. - NFI Master Hearth Professional on September 23, 2013
Answer:The 30 degree offset pair would be the ideal item to use in this scenario. Each offset pair will provide you with approximately 4 inches of offset, but it is possible to add sections of pipe in between the elbows to achieve further offset.

Does this offset separate? I need to offset about 24".
By Collin C. - NFI Master Hearth Professional on June 11, 2013
Answer:This offset elbow kit will indeed separate and can be used in conjunction with a length of pipe between the elbows to achieve different offsets. In order to achieve a 24" offset, a 48" length of pipe will need to be used between the elbows.

Will this 30 degree elbow kit high-temperature double-wall wood-burning chimney work with 8 inch double wall flex liner?
By eFireplaceStore on December 22, 2015
Answer:This offset kit should only be used with the FMI/Superior 8HT chimney pipe system. It is not configured to adapt to flexible venting or any other Class A chimney system.

Can I join a three wall vent pipe with a two wall vent pipe?
By eFireplaceStore on June 2, 2014
Answer:Unfortunately, no. The same Class A chimney pipe must be used from start to finish by code. This is due to the fact that each system is tested and listed to use only the same series of parts. Any conversion could cause a dangerous buildup of heat at the conversion point.

Does this elbow rotate or does it stay in a fixed position?
By eFireplaceStore on October 17, 2014
Answer:These elbows can swivel on their base to change the direction that they are pointing, however the actual 30 degree angle of offset is fixed.

I need to offset my flue 5 or 6 inches to avoid a rafter. Will this offset do the job? Would you have an adapter to transform an 8" X 12" clay tile to a round pipe?
By Collin C. - NFI Master Hearth Professional on September 5, 2012
Answer:This offset could indeed be the item for your needs. However, it is only meant to be used in conjunction with other FMI 8" chimney components.
Do you need to offset a clay flue or metal chimney? We do sell a metal chimney adapter that would allow you to convert a clay flue to metal chimney, at the chimney's termination. This is often used to extend a damaged brick chimney or a chimney through a new, taller roof line.

My old fireplace sat back further than the new one so in order for the chimney pipe to be centered in the shroud cover I would need some sort of an offset
The difference is about 5 inches. Could I use an elbow for this?
By eFireplaceStore on September 23, 2014
Answer:You can indeed, as long as the new fireplace and old fireplace use the same series of chimney pipe. This pair of 30 degree offsets yields 4 1/8 inches of offset when used together. This should be enough to complete your installation. The chimney pipe can make up the additional 7/8 of an inch by leaning it slightly.

How much does the one offset and return provide? All I need is about 2 inches offset.
By Collin C. - NFI Master Hearth Professional on February 28, 2013
Answer:A single pair of 30 degree offsets will shift the pipe by approximately 3 3/4 inches total.

We need to offset the chimney pipe 6". What combination of pipe and 30 degree offsets do we need?
By Tyler M. - Fireplace Specialist on January 9, 2013
If you are using this FMI 8" inner diameter double-wall air-cooled chimney pipe, please see page 9 of
this owner's manual
for the appropriate offset chart. Putting two 30-degree elbows together will create only a 4 3/8" offset, so you will need to put one 12" 8DM pipe length
between these elbows, which will give you a 9 3/4" offset with a 25 1/2" rise.
