Pipe Identification
4.0 Installation
4.1
1. It is essential that the pipes supplied are identified
correctly & joined and connected accordingly (Fig. 4):
• Pipe A - DHW Upper Pipe
• Pipe B1 - DHW Lower Pipe (see table 1 for boiler
• Pipe B2 - DHW Lower Pipe (see table 1 for boiler
C
• Pipe C - Mains In Upper Pipe
• Pipe D - Mains In Lower Pipe
2. Pipes A & C connect to the Assure FGHR unit.
Pipe B1 or B2 connects to the cold water inlet.
Pipe D connects to mains cold water.
3. Before soldering Pipe A to B1 or B2 and Pipe C to D
ensure that the nuts are fitted to A and C.
4. Note the identifying indentations in Pipes C & D - Pipe
A must not be connected to Pipe D. Pipes B1 & B2 are
identified by a label.
D
5. Ensure that the horizontal legs of Pipes A & B1 or B2 are
offset slightly as illustrated (when viewed from above)
before soldering (Fig. 5).
6. An offset of 3° ensures that Pipe B1 or B2 will connect
correctly to the cold inlet tap and allow Pipe A to clear
the boiler adaptor.
