FITTING THE OPTIONAL

ADD-IN BOILER

The boiler replaces the rear firebrick.

Before fitting the boiler, remove the front fence, the throat plate and the rear firebrick. Knock out the knock-outs for the boiler tappings in the back of the firebox.

Remove the back nuts and washers supplied with the boiler and fit the boiler into the appliance. Place the fibre washers over the tappings on the outside of the appliance and fit the two backnuts, ensuring that the boiler is held tightly against the rear inside face of the appliance and that the top edge of the boiler is level or runs uphill to the flow tapping.

Gaps between the boiler and the firebricks should be filled with fire cement.

Connect the boiler to the heating system ensuring that the flow pipe rises continuously from the boilerto the open vent. Fill the system with water and check for leaks.

CONNECTIONS TO FLUES

There are several ways of connecting the stove to the flue. These are illustrated in Figs. 4 to 7.

If the optional vertical rear flue connector is used then the chimney may be swept through the appliance.

Horizontal lengths of flue must be kept to a minimum and should not be more than 150mm (6 inches) long. The sealing face of the flue collar must be coated with fire cement before fixing to the body of the stove using the two screws provided. The blanking plate must be removed, sealed with fire cement and refitted, care being taken to ensure that the fold on the clamping plate is in line with the lugs on the firebox as shown in Fig. 8. Ensure that the clamping plate does not prevent the throat plate from seating correctly. All flue connections must be well sealed.

SOOT DOORS

It is possible to pass a 16 inch diameter sweeps brush through the appliance but in most back outlet installations it will be necessary to have a soot door to enable the chimney to be swept. The optional vertical rear flue connector does allow the
