Jacket assembly
1. Fit cast iron hinges(143) used for carrying front door onto front
section using 2 M8x30 setscrews (142) for each hinge.
Before assembly of front door (131), first decide the side of hinging
(for LH or RH opening). Screw hinge pins (141) into threaded holes.
Screw a M16 nut (49) onto each hinge pin as shown in figure below

Hang the front door on M16 nuts. Position the front door up or
downwards by losening or tightening the M16 nuts.
2. There are two types of retarders. One is the second pass retarder (95) or (99) and the
other is the third pass retarder (for 4,5,6,7 sections) (97). Second pass retarders consist
of two stainless steel bladed modules (95 and 99). The modules are combined together
according to following table for preparing second pass retarders. Retarders are placed into
second and third flue gas passages of boiler as shown in following pictures:
In case of light or medium fuel-oil firing, the second pass retarders should not be used,
and input to boiler should be slightly reduced to values given in technical informations.

setscrews(136) and 10.5 washers(137).
