4.6 Pipework

When the front tappings are used, it is essential that any
pipework of fittings do not project more than shown in diagram
4.5.

When using a rear tapping with Rc (1in BSP) fitting for 28mm od
pipework, it is recommended that a short nipple and an R thread
(BSP) to copper elbow is used. If the pipework is required to
run back to the wall, make sure that it will clear the boiler air duct
and, if working to minimum clearance, does not stick out too far
from the boiler, see diagram 4.6.

Do not route any pipework, water or gas, across the front of the
thermostat pocket, controls or combustion chamber cover.

The gas pipework must be along the right hand side of the boiler.

4.7 Balanced Flue Terminal

(Standard and short flue)

Mark out and cut a hole through the wall where the boiler is to
be installed, to the dimensions shown in diagram 4.7, after
checking that sufficient clearances will be left around the boiler
as described in Section 1.7.

Place the boiler in position. The balanced flue ducting will
project into the prepared hole in the wall.

Make a good seal around the boiler air duct on the inside wall.

Take the balanced flue assembly from its carton and remove the
four screws to release the outer baffle, see diagram 4.8.

Remove the four outer wire guards then pull off the inner baffle
and flue duct assembly.

Place the air duct assembly into the hole in the wall from the
outside, engaging it around the air duct on the boiler and sliding
it until the wall plate contacts the outer wall surface.

Seal the joint in the air ducts with the yellow tape provided. Tape
four pieces into the four inside corners, followed by four along
the joints, overlapping the corner pieces, to make a good seal.
Allow a minimum of 20mm (

in) overlap of ductings.

Cement around the wall plate to make good and weatherproof.

Refit the inner baffle and flue duct assembly, sealing the joint
with the heat resistant semi-transparent tape provided.

Refit wire guards, outer baffle and secure with screws.
