Recently had an M55i installed in our new home. Picked this over the Harman. Installer did a test burn, which went great. My question is regarding the damper slider. The manual doesn’t say which direction you use to open/close.
So if I pull the damper out (left), does that give or reduce air flow.
Thanks
