The Metos OEM pizza ovens are supplied with a heat storing cooking plate made of re-
fractory bricks, the oven is insulated with evaporated rock wool. The oven is fitted with
protected heating elements. Temperature can be thermostatically adjusted between 0-400
ºC. Top and bottom heat independently adjustable. The oven chamber is fitted with light-
ing and an exhaust chimney. All models (except MF2) supplied with glass windows and
door handles with thermal insulation. Oven front of stainless steel. Frame and stand of
powder coated steel. The ovens are stackable.

To switch on the chamber light, turn the internal light switch. We suggest not to keep the
light on at all times, use it when you chek the baking only. This will increase the lamp
duration.

Don’t undervalue the the importance to use the chimney; in fact if you keep the discharge
valve closed while you cook pizza, you will see the steams going out from the oven door.
Further more the upper heating element action will be remarkably slowed down by the
steam: Pizza will burn on the base and will not bee cooked on the top. If you connect the
chimney direct to a mechanical aspirator it will collect too much heat from the oven com-
promising the performance: Pizza will be too dry and burnt on the base. Therefore it is
very important to connect the chimney with a good draught flue or under a suction hood.
