(polypropylene) or
AL29-4C (UL 1738/UL
C 636) system
The boiler is not supplied with the fi ttings
needed for separate vent and combustion
air systems. A special kit must be ordered
to connect the boiler to separate vent and
combustion air systems. Figure 45 shows
fi tting “A” that can freely turn 360 degrees
for optimum installation versatility.
Pipes or elbows connected directly to
the boiler, must be mechanically secure.
Follow these instructions (make reference
to fi gure 46):
1. prepare the two collars “G” with springs
“E” and “F”;
2. insert the collars “L” in hole “M”;
3. insert pipe “N” inside fi tting “A”
4. tight the two collars “O” in a manner to
mechanically secure pipe “N” to fi tting
“A”,
DO NOT FORCE.

Horizontal vent sections must always
be pitched by at least 1/4 in/ft (21
mm/m) towards the boiler. Horizontal
combustion air sections must always
be pitched away from the boiler by at
least 1/4 in/ft (21 mm/m) to prevent
rain from entering the boiler. The vent
and combustion air intake systems can
be extended up to 300 ft. Each 90°
elbow has is equivalent to 5 ft (1,5m),
of straight pipe. Each 45° elbow has is
equivalent to 2.5 ft (0.75 m), of straight
pipe.
