5 - COMBUSTION AIR AND VENT PIPING
5.6 Coaxial Venting Instructions
Maximum equivalent flue lengths for Coaxial venting are:
Coaxial Elbows - Equivalent length
4"/2" [100 mm/60 mm]
45°
1.64 ft. [0.5 m]
90°
3.28 ft. [1.0 m]
5” / 3” [128 mm/80 mm]
45°
1.64 ft. [0.5 m]
90°
3.28 ft. [1.0 m]
Coaxial Termination - Equivalent length 3 ft (0.9m)
NOTE: Coaxial venting can run horizontal or vertical.
•
Connect flue elbow to top of boiler and adjust direction of
elbow to desired orientation (rear, right or left).
• Measure distance from outside wall face to elbow, this
dimension will be known as 'X", add distance "Y" + 2" (60
mm) to "X" this is the total dimension of the vents or use
venting manufacturers instructions. See Figure 5-2.
• Mark dimension from above on outer aluminum intake
vent. Measure length of waste material, and transfer
dimension to inner grey flue pipe.
•
Remove waste from both vents (flue and air). Verify cut
ends are square and free from burrs. Insert flue back into
intake air vent and pass them through hole in wall.
• Check all measurements before cutting. Clearance to
combustible materials is zero when using coaxial vent
system.
• After installing venting use calibrated analyzer to verify
there is no recirculation of combustion.
• Ensure horizontal termination with fresh air slots on the
bottom.
WARNING
Asphyxiation hazard. Before securing the screws
ensure the pipe has been pushed in a minimum of
1-3/4" (45 mm) into the gasketed end of the other
pipe. Failure to follow these instructions could result in
death or serious injury.
