Quadrafire CB1200 FS combustion issues

[planeman125]

Hello, I am having trouble with a CB12000 FS unit.

When I turn the unit on the combustion fan comes on high like normal. After it ignites the fan kicks down to lower RPM and fire is lazy and it does not heat the stove like normal.

I have already replaced the cumb fan and the control board. I think my next move is to turn the control board to #2 and see if the increase helps.

Thoughts or recommendations?

Yep,stove and/or exhaust has a restriction,everything needs cleaned.

Stove has been fully cleaned by an experienced service tech. Checked the gaskets and sealed the clean out door.

Cleaning the stove is 1/3 of the cleaning process.

I assume you're referring to cleaning the venting and the components? All been done.

Then you need to have a stove technician come in and get you up and running

After a stove ignites, it will go to whatever fan speed you have it set on. kap

Turned out to be a combination of cleaning under the pedestal and significant wear of the burn pot gasket.

Glad you figured it out, before it cost you some coin. Stay warm. kap
