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.
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 is positioned with fresh air
slots on the bottom.
WARNING
Asphyxiation hazard! Before securing screws
ensure the pipe has been pushed in a minimum
of 1-3/4" (45 mm) into the gasket end of the
other pipe. Failure to follow these instructions
could result in death or serious injury.
