7.0 Installation

INSTALLATION SEQUENCE

There are 4 main elements to the installation of the Baxi Bermuda BBU 15 HE:-

Preparation of pipework & opening

Inserting the flue into the chimney

Siting & fixing the boiler

Fitting the terminal assembly

The sequence in which these are performed may depend upon various factors beyond the scope of these instructions. The above list is intended as a guide based on a typical installation.

It is not necessary to open the firefront pack until the boiler and flue are installed, and the boiler is ready to be commissioned. The firefront pack includes full instructions.

7.1Initial Preparation

1.Remove the outer carton from the boiler pack. Discard the packing pieces and remove the fitting kit.

2.Ensure that the base of the builders opening is clean and level.

3.Complete any pipework installation and routing of electrical cables within the builders opening that may be difficult once the boiler is in place.

7.2Flue System

1.The actual length of flue (as opposed to the vertical distance from the boiler top to the chimney outlet) MUST be established before commencing.

2.The flue must have a minimum vertical height of 3m and have no bends greater than 45°.

NOHORIZONTALRUNSAREPERMITTED!

3.Depending on the actual flue length it may be beneficial to shorten the flue at this point to enable easier handling.

4.Take one of the 60mm lip seals supplied and fit to the first groove in the flue duct. Also fit the 100mm lip seal to the air duct. (Figs. 17 & 18).

NOTE: Talcum powder may be used to ease fitting of the adaptors over the seals. DONOT use oil, grease or soap.

5.Unfasten the clips on the boiler adaptor and insert the end of the flue duct with the seal into the 60mm socket. Ensure the seal is positioned past the clips, then engage the clips over the larger diameter ‘rib’ on the duct (Fig. 19).

6.Repeat the process for the 100mm air duct (Fig. 20)
