Figure 10 – Cascaded Boilers – Space Heating
FIGURE NOTES:
1. This drawing is meant to demonstrate system piping concept only.
2. Install a minimum of 12 diameters of straight pipe upstream of all circulators.
3. Install a minimum of 6 diameters of straight pipe up and downstream of all closely spaced tees.
4. Piping shown is Primary/Secondary.
5. The minimum pipe size for connecting a Mod Con boiler is 3” for both the 1000 and 1700 models. See Multiple Boiler Manifold Piping chart, Figure 6
in this manual, when sizing and installing a multiple boiler system.
6. System flow (Secondary Loop) must be greater than the boiler’s Primary Loop flow.
7. Installations must comply with all local codes.
8. System sensor must be placed as shown in drawing.
