MOUNTING THE 2-STAGE RIELLO BURNER:

It is necessary that the insulation gasket be placed between the mounting plate and the burner flange. The insulating gasket has six holes, which, if necessary, can be modified as shown. (see figure 14-1)

Figure 14-1: Burner gasket and mounting Figure 14-2: Burner fixing and hinge assembly

Verify that the installed burner is lightly leaned towards the button. (See figure 14-1) The burner is designed to allow entry of the flexible oil-lines on either side of the burner.
