WARM AIR HEATER SERIES RAPID
*Equivalent length for wide radius elbows.
** The loss refers to one meter of pipe. When you specify the code, indicate the length in cm instead of xxx.

Guidelines to Component Selection
The following table lists pressure drops of more commonly used
terminals and piping.
If the terminal is not directly connected to the heater and a
distance is to be covered, check that diameters of terminals,
extensions and elbows are correct.
Refer to the table below to assess pressure drops for each
component according to the heater model that was chosen.
Sum pressure drops of each component and make sure the
result does not exceed the available value for the heater to
use. If an air intake pipe is used, sum its pressure drop to that
of flue outlet.
If the result is higher, use pipes with larger diameter and check
again the sum. A pressure drop higher than the pressure avai-
lable on flue system would reduce the thermal power output
of the heater.
Note:
The figures in the following pages show examples of
venting and air intake piping built using standard kits. The ta-
ble below shows maximum lengths of layouts that can be built
between the unit and the terminal. If elbows are included in the
layout, the equivalent length of each elbow must be deducted
from the available length.
