I open the chimney, open the air intake. I use dry newspaper: 4 sheets crumpled into balls. I put small sticks of wood on top, and smallish sticks on top of that.

The security light will blink when either door, hatch, or hood is opened and will continue blinking until it is closed. Check all 4 switches for proper operation. If the bad switch is disconnected it should turn off the light. If the security light is on constantly instead of blinking that is to let you know that the alarm system is activated and should turn off after a few minutes.
The world record for not blinking is 32 hours or so.
