Installation Guide for Danfoss SSM Stainless Steel Manifold

Quick guide from the manual

This document provides essential dimensional data and flow balancing information for the Danfoss SSM Stainless Steel Manifold. It is intended for professional installers setting up underfloor heating systems. The guide focuses on determining the correct manifold length based on the number of circuits and configuring flow settings according to pipe dimensions and circuit lengths.

Dimensional data

The SSM Stainless Steel Manifold is available in various configurations ranging from 2+2 to 12+12 circuits. The total length (L1) of the manifold depends on the number of circuits installed. Ensure you have sufficient space for the installation based on the following dimensions:

• 2+2 circuits: 190 mm
• 3+3 circuits: 240 mm
• 4+4 circuits: 290 mm
• 5+5 circuits: 340 mm
• 6+6 circuits: 390 mm
• 7+7 circuits: 440 mm
• 8+8 circuits: 490 mm
• 9+9 circuits: 540 mm
• 10+10 circuits: 590 mm
• 11+11 circuits: 640 mm
• 12+12 circuits: 690 mm

System configuration and balancing

To ensure efficient operation of the underfloor heating system, the flow must be balanced based on the specific pipe diameter and the length of each heating circuit. The manual provides reference tables for two common pipe sizes:

• 16 x 2 mm pipes: Use the corresponding table to find the flow setting based on circuit length (10m to 100m).
• 20 x 2 mm pipes: Use the corresponding table to find the flow setting based on circuit length (10m to 120m).

Locate the intersection of your circuit length and pipe diameter in the provided tables to determine the required setting for the manifold flow meter.
