3. Push in the knob, turn counterclockwise to PILOT, hold it and click the piezo until the pilot lights
4. Hold a few seconds then release; repeat if the pilot drops
5. Turn to ON with the burner switch on; main burner lights in under 4 seconds

Rock wool and first burn tips

Majestic · DVBL7 series

Getting a good flame picture on a new install.

4. Burn the first 10 hours with the blower off and windows open for the burn-off smell
