Fireplace

The fireplace lever is located on the wall behind the fireplace, next to the study desk.
Press POWER on the remote and a light will appear a few seconds later (about 15 seconds).
Make sure the temperature in the middle of the remote is higher than that at the top of the remote.
The flames will then start.

Firewood is at your disposal for the outdoor fireplace.
You can find the firewood stacked near the hot tub.
