must not exceed the value
Pmax quoted in Table 3.3.
3.3 EVOMAX CASCADE FLUE SYSTEM DATA 3.4 DESIGN PROCEDURE
1. Determine the required total heat output. (Htot) [maximum
of 6 boilers per system].
2. Determine the required minimum heat output.
3. From Table 3.3 select the Evomax models required.
4. Using Figure 3.5 read the Combustion Products Flow Rate
(Qmax) at the Total System Capacity (Htot).
5. Record the information in Table 3.6
6. Calculate the maximum permissible ue length at
conditions Qmax & Pmax.
L = [a – (c + d)] / b (Table 3.6)
