C13/C13X installation type
KC 12 - KR 12 - KRB 12
• Minimum permissible length of horizontal coaxial pipes is 1 meter.
•
Maximum permissible length of Ø100/60 mm horizontal coaxial pipes is 9 meters, first curve included.
•
Maximum permissible length of Ø 125/80 mm horizontal coaxial pipes is 30 meters including the first elbow connected to the boiler.
• For each additional 1 meter of straight pipe maximum permissible length is to be reduced by 1 meter.
• For each additional 90° elbow, maximum permissible length is to be reduced by 1 meter.
• For each additional 45° elbow, maximum permissible length is to be reduced by 0.5 meter.
• The wall terminal reduces maximum permissible length by 1.5 meters.
• The air intake duct is to be tilted down by 1% toward its exit, in order to avoid rain water to enter it.
•
The flow resistance of the first elbow shall not be taken into account to calculate maximum permissible length.
