Important: maximum linear length 3 mt. after the flue elbow;
for every 45° flue elbow consider 0.5mt less;
for every 90° flue elbow consider 1 .Omt less.
The Extension Kit for RSM20/FB id.n° R3501693 consists of:
- Imt. air intake pipe 0100mm. (see n°8 in the enclosed drawing).

- Sealing washer 0100mm. (6) with fixing clamp (10).
On Request:
-R3566490 90° elbow 0100mm/60mm without test points;
-R3566445 45° elbow 0100mm/60nim without test points.
PREPARATION
1 )Remove the elbow (4) after having loosened the respective fixing clamp (10), then remove the standard
concentric flue kit Imt. long.
2)Fit the ORs (3) and sealing washers (2) to the flue elbow (4), and then fit the elbow onto the fancsocket (1)
on the top of the boiler.
3)Drill a hole 110mm of diameter through an outer wall, in line with the flue bend (4) (see also the dimensions
in the Boiler Installation Instructions).
INSTALLATION
l)Properly position the centralising springs (9); insert the flue pipe extensions 060mm (7) one into the other
and then into the standard flue pipe (5).
Shorten, if necessary, always from the plain end of the pipe.
2)Position the sealing washer for pipe junction 0100mm (10) on one end of each air pipe extension
0100mm (8).
3)Fit the air pipe extensions (8) one to the other; properly position the sealing washer (6) on each pipe
junction and tighten it by means of the specific clamp (10).
In case of shortening, cut the air intake pipe of the same length as the flue pipe.
4)Fit the extended flue pipe into the extended air pipe.
5)Fil the wall finishing washer (11) onto the end of the assembled concentric duct.
6)Insert the extended duct into the hole through the wall; make the air pipe slide a little, then fit the flue pipe
into the concentric flue elbow (4).
7)Approach the extended air duct to the flue elbow; properly position the sealing washer (6) and then fix the air
duct to the elbow by means of the fixing clamp (10).
8)Properly finish the internal wall face by means of the wall finishing washer (11).
