IDEAL INDUSTRIES HE12, HE24, HE18 General Boiler Water Connections, Rear Flue only, Side Flue only

GENERAL

1 BOILER WATER CONNECTIONS

The boiler flow and return pipes are supplied fitted to the boiler ready for top connection

Notes.

a.For the heating loads in excess of 60,000 Btu/h, 28mm (1") flow and return pipes should be used to and from the boiler.

b.This appliance is NOT suitable for use with a direct hot water cylinder.

2 BOILER CLEARANCES all dimensions in mm (in.)

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

aProvided that the flue hole is cut accurately, e.g. with a core drill, the flue can be installed from inside the building where wall thicknesses do not exceed 600mm (24"). Where the space into which the boiler is going to be installed is less than the length of flue required the flue must be fitted from the outside.

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.

REAR FLUE ONLY

MIN. Top clearance required = 145 mm (5 3/4")

Front clearance

The minimum front clearance when built in to a cupboard is 5mm (1/4") from the cupboard door but 450mm (17 3/4") overall clearance is still required, with the cupboard door open, to allow for servicing.

N.B. The boiler will not fit into a standard depth wall unit. In

order for it to do so the plastic fascia should be removed. See Frame 41.

*Bottom clearance

after installation can be reduced to 5mm in an adequately ventilated enclosed cupboard. However, 100mm must be available for servicing.
