Regency allows 6" and 5.5" as well as any liner with equivalent volume.

5.5" might be ok. Is this a basement or 1st floor install?
1st floor

@bholler - yes, I read that and was just wondering if there is an advantage to one size or the other. In theory 5.5" should be a bit cheaper than 6" (less material) but is there an advantage to having a 6" I'm not aware of? 20% more volume in the flu - less resistance, etc? I know a few people in this thread have had draft issues and just want to make sure I'm not missing something.

5.5 costs more than 6

Hi,

I recently had an Hi500/Ci2700 installed and just began to use it a couple of days ago.

I'm only getting a 4 hour burn time. That is from the time the stove is packed, the bypass is closed and the damper is set to 0%, it's only 4 hours before the cat time drops back below 500 and there is little left in the stove.

Does this seem right? Here is the timeline and details.

Equipment

Regency Ci2700/Hi500
chimney dimensions 18 feet by 6 inches
chimney location: interior
1/4 inch foil blank kit (I guess this wraps the liner?)


Fuel: 1.5 to 2.5 year seasoned hardwood (oak, maple, cherry, black birch)

Timeline

t = 0

STARTING STATE
2 inch coal and ash bed
cat temp: 130

Thanks for any info!

That's not too far off from normal. Cat temp 481 after 4 hours isn't horrific. Go inside the firebox, there is a metal hood in the bottom center, closest to the door. Loosen (not remove) the 2 bolts, and see if there is a small metal plate that you can pull up and out. If there is no metal plate at all, you can remove the metal hood to be 100% sure. If you truly don't have the metal plate, then contact your dealer for one. 2600's didn't have it at first, and then later on got them. It reduces the air. I'd say this is worth verifying.

Thanks very much for the advise! I'll check it out.

Hey guys. I have the i2700. What should be my operating temp? What is to hot for these inserts to be working at? I have a Digital thermostat. I just want to make sure I’m operating safely.

Is the digital thermometer on the cat or the flue? If on the cat, the temp range will be from 500º to 1600º. Close the bypass when the cat gets above 500º.
