Assembly sequence (Ref. fig. 29)
A) Mount the insulation (pos. 1) of the boiler body and secure
the 2 edges with the elastic straps (pos. 2) supplied in the
accessory box, hooking them to the external fabric part of the
insulation.
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 in the plate cuts.
To determine which is the right side and which is the left side,
refer to the cable gland plates (pos. 11): they must face the
front of the boiler.
C) Fix the middle rear panel (pos. 15) and the top rear panel
(pos. 8) with the specific self-threading screws.
D) Rotate the cover of the panel board frontwards after having
removed the two screws on the side and insert the electric
inlet cables and the outlet probe capillaries through the slots
at the base.
Fix the panel board to the upper panel (pos. 10).
Fit the upper panel pos. 10, complete with panel board, to the
two sides of the casing.
E) Insert into the conduits the bulbs of the instruments
as shown
in Fig. 30 and wire the panel board to the power 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.
F) Fit the upper longitudinal panels (pos. 12 and 13) hooking
them to the sides.
G) Fix the installation and boiler data plate (pos.14) to the side
