2Alpha CombiMax Remote Location
The Alpha CombiMax has been designed to fit onto the left hand side
of an Alpha 240/280 boiler. However, it is now possible (using a
CombiMax 350 or 600 produced after February 1999, i.e. from Serial
No. A906) to install it up to a distance of 1 metre from the boiler in the
positions shown in Fig. 1.
The pipework between the boiler and CombiMax must be kept as
short as possible and be no more than 1 metres in length, with the
number of bends kept to a minimum.
Notes: 1. A CombiMax produced before February 1999, i.e. before
Serial No. A906 must not be fitted remote from the boiler.
2. A CombiMax fitted remote has no casing.

2.5 Filling Loop
With the CombiMax in a remote location from the boiler, the filling loop facility supplied with the boiler cannot be used
as designed. The filling loop should be discarded and its connections on the cold mains inlet valve (CombiMax) and
heating return valve (boiler) sealed, using ½" BSP threaded caps (not applicable to Alpha 240X). See Fig. 4.
2.6 Connecting Pipework
The boiler and CombiMax must be connected together as shown in Fig. 4, using 15 mm pipework. The pipework
supplied with the CombiMax can be utilised to provide the connections at the boiler and CombiMax.
2.7 Electrical Supply
Connect the electrical supply cable directly to the CombiMax terminal block as described in the CombiMax
instructions, ensuring the cable is secured with the clamping bush supplied.
The cable supplied fitted for connection to the boiler will be too short and therefore must be removed from the CombiMax
terminal block terminals 1, 2 and . A longer length cable to the same specification stated in the CombiMax instructions
must then be used to connect the electrical supply to the boiler terminal block from the CombiMax.
Note: Connect this electrical supply to the boiler as described in the boiler instructions.
