A method to adjust and focus heat effects inside a glass tempering furnace on different structural elements and an air space and parts of the air space, in which method the glass (1) to be tempered travels on a conveyor of horizontal rollers (4) through the furnace and the glass sheet is heated by means of heating elements (2, 3) placed on the upper and the lower side of the glass sheet. By intern convection started in the furnace lower part in the final stage of the heating cycle the heat effect from the furnace lower part heat elements (3) on rollers (4), carrying the glass sheet, is deducted, circulation of air in the lower part is stopped when a new cold replacement glass sheet has reached a temperature of approximately 100 DEG C and by means of adjustable blasters of circulation air (8) in the furnace upper part the hot air motion and the heat effect on glass sheet (1) is adjusted and intensified in the final stage of the heating cycle when the glass temperature exceeds 400 DEG C.
