B) Position the side panels (pos. 3 and 4) with the lower bend
inside the L-shaped profile at the base of the boiler body and
hook the upper part to plate junction profiles.
To determine which is the right side and which is the left side,

at the base.
Fit the panel board to the upper panel (pos. 10).
Fit the upper panel (pos. 10), complete with panel board, to

line, to the burner and to any pumps, etc.
Close the cover of the electric control board.
Guide the burner plug through the side plate (pos. 11) on
the preferred side and secure the cable with the cable gland
supplied.
Fasten the plates (pos. 11) to the sides of the casing.
Secure the electric cables coming out from the rear of the
boiler with the cable clamps, tightening them moderately.
E) Fit the upper longitudinal panels (pos. 12 and 13) to the
