Control the temperature

The draft door and the cap

The draft door lets air in, the cap lets it out. From the manual.

1. Do not let it overshoot for a low cook: coming down from very hot takes a long time.
2. Once at temperature, close the draft door to about 1 to 2 cm.
3. Fine-tune with the slide on the cap.
4. Open either vent for more air and more heat; close them to bring it down.
5. Adjust the vents in gloves or with tongs: they get very hot.

The manual gives a usable range of 80 to 400 °C. Monolith publishes no table of vent positions against temperature.

The Guru port and kill plug

• Every Junior Pro 2.0 has the port low on the left of the base (catalogue 2021; the drawing asks for 165 mm free beside it for the fan). Without a fan, keep the kill plug (221034) in it, or air leaks in.
• With a fan, Monolith's 2019 FAQ (written before the Pro 2.0) closes the top vent to about ¾, starts with a small fire and keeps the lid shut at the start.
