Page 7: Oil Burner Technology
Filter Internal Pump Filter OMNI’s patented burner technology improves the efficiency of the oil burn process by continuous stabilization of the oil viscosity. Optimum atomization (spray) is accomplished by precisely pre-heating the oil and air prior to introduction to the combustion chamber. - Page 8 When you increase or decrease the fuel to the burner, you will notice the flame length will increase or decrease. Adjust flame length so flame is just slightly less than halfway down main combustion chamber tube. OMNI by EconoHeat Page 8...
