Sizing Liner Cap

[oskar470]

The new Regency I2450 insert is installed and working good but I feel there is no enough draft. The installer checked my liner and said it is good so I kept the old 6" liner and cap

I remember about 15 years ago the liner cleaners told me that my cap was too small and suggested to replace with a larger one and I agreed but when the time came to light the fireplace I had a huge draft and so I switched back the old cap. So I conclude the cap controls the draft

My old insert had a firebox size 2.9 cu.ft and the new 2.3 cu.ft. Are any rules how to select the size of a new cap?

Thanks

Have the installer adjust the flue deflector plate or replace it with one that permits a little more clearance. The dealer should have multiple sizes for this purpose.

This is internal, above the baffle.

Yes I understand that it's internal

To adjust the deflector or replace it do we have to remove the insert?
Thank you

No. It can stay in place. The two front tubes and the baffle need to be removed. Look at page 23 of the manual for the steps.

Yes I now see page 23 and the schematic explains all of it. If I can't get a technician I may do it myself
The schematic says to make sure the deflector is pushed UP as far as possible, tight to the top of firebox
Perhaps that's my problem, its not pushed up as much.
Many thanks
