My enviro M55 will not hold a consistent flame. It has the blowtorch flame. Have reduced the combustion air trim and attempted to check the damper but have not been able to find the solution to the damper. I see the screw head for the damper area but it looks like a fixed metal plate above it and the little area on the side panel that a hole should be is not punched out. No way to change the damper setting. It does have the fresh air unit installed. Could this be drawing in too much air? Barely heats our small living room even when cranked up to 5. It is a 2011 model. The video is the flame with stove set on 4, pellet trim feed on 5 and combustion air on 1. Not sure how to proceed any longer

Is the stove on a thermostat?
What mode is it running in
Manual.
Hi/Low
On/off
 
Is it am m55 FS Steel
FS Cast or an insert?
 
The damper slide plate is held by a 3/8 bolt
It has to be loosened in order to slide the plate.
If the damper does not move it has to be removed
and cleaned also the area where it is located.
The easiest way to clean is with the combustion blower removed.
The grooves that the damper slid in have to be clean I
use a thin-bladed screwdriver to scrape clean.
Here is a film clip of what the flame should look like
