GENERAL

1 BOILER WATER CONNECTIONS

This appliance in NOT suitable for use in a direct hot water system or for gravity circulation.

2 BOILER CLEARANCES

The following minimum clearances must be maintained for operation and servicing.

Additional space will be required for installation, depending upon site conditions.

Side and Rear Flue

a.Provided that the flue hole is cut accurately, e.g. with a core drill, the flue can be installed from inside the building.

Installation from inside ONLY

b.If a core boring tool is to be used inside the building; the space in which the boiler is to be installed must be at least wide enough to accommodate the tool.

Front clearance: 450mm (17 3/4") from the front of the boiler casing.

Minimum front clearance when built behind a concealed panel is 5mm (1/4") provided that the top and bottom of the casing is not enclosed and the side clearance is 40mm (2") at both sides.
