BICALOR Combination Boiler Assembly Completion
The BICALOR can be fitted with top mounted calorifiers of types
CS 400-9, CS 500-4, CS500-6 and CS 625-8 depending on the
boiler output and the hot water requirement
Assembly of calorifier
-
Fit blank flanges at the top and bottom front
- Fit boiler flow header to the rear at the top and boiler return
header at the bottom
Fit 2 ½” plugs in the boiler return header
-
Place calorifier support on the boiler block
- Place calorifier on support
- Align calorifier

7. 2x½ “ x 150 Long immersion sensor pockets from the
instrument panel are to be fitted into the boiler flow header.
If no circulating pipe has been supplied with the delivery then the
piping must be constructed and made available. In addition, the
non-return valve is to be fitted as per the diagram. The
measurements from the centre of the pipe to the centre of the
boiler (280 mm and 420 mm) must be observed.
Cold Water Pressure Test
The assembled boiler block should be given a water pressure
test of 1.5 times the excess operating pressure. The test excess
pressure, however, must be at least 1 bar higher than the
operating excess pressure.
The highest test excess pressure is as follows:
-
with a normal construction 6 bar
- with a multi-storey construction 8 bar
The hot water secondary side may be tested to 13 bar.
