HOT Water System, Boiler | Rayburn 212SFW, 200SFW specification

Minimum clearance to combustible materials 150mm.

Fig. 1

The cooker fully meets the requirements of BS: 1252 and is fully approved by the HETAS Ltd Approval Scheme.

Air for combustion within the firebox and the rate of burning is determined by the manually operated spinwheel control on the ashpit door and flue damper.

With normal usage in 24 hours continuous burning the Rayburn Cookmaster Plus 212SFW has an approximate output of 100 gallons of hot water. To provide 2 or 3 hot baths at intervals and normal household requirements, the following conditions must be fulfiled:-

HOT WATER SYSTEM

Rayburn Cookmaster Plus 212SFW - It is recommended that a 140 litre (30 galls) indirect hot water storage cylinder of the double feed type, (e.g. manufactured by Albion Cylinders) complying with BS 1566 Part 1: DF Type 8 should be lagged and fixed vertically as near as possible to the cooker.

The maximum water pressure is 1.75 bar.

The water capacity of the boiler is 7 litres.

The 28mm minimum diameter primary flow and return pipes must not exceed 10m in length and pipes longer than 5m must be lagged.

Ensure that the flow pipe has an open vent and rises continuously from the boiler to the cylinder to ensure good gravity circulation.

The water draw-off pipes to the taps must be dead-leg connection from the vent/expansion pipe.

A towel rail of not more than 0.5m2 heating surface may be heated providing the flow and return pipes are not more than 5m each in length, and provided the cylinder

and towel rail are lagged. When the hot water storage cylinder is very closely coupled to the boiler, a towel rail is advisable as a heat leak, and lagging should not be applied. A radiator is not recommended.

To obtain the boiler outputs the fire must be idled overnight, and daytime cooking take place.

All installations must be fitted with a drain tap at the lowest point of the system.

IMPORTANT NOTE: THESE INSTRUCTIONS MUST BE STRICTLY OBSERVED. IF THEY ARE DISREGARDED (E.G. AN UNLAGGED OR OVER- SIZE CYLINDER), CONSUMPTION OF FUEL MAY BE EXCESSIVE, AND THE COOKER DAMAGED BY OVERFIRING.

In some circumstances it may be possible to overheat the appliance and the water inside will boil. This will be evident by the sound of a knocking noise coming from the appliance and pipes around the house. If this occurs close off all air controls and manually start the central heating pump if fitted. Opening the oven doors and hotplate covers will help to release heat from the appliance. Be aware that steam and boiling water will be expended from any open vent from the heating system probably in the roof space at the expansion tank.

THE BOILER

Rayburn Cookmaster Plus 212SFW - Unscrew the sheet metal cover plate on the side of the cooker and remove the insulating material from behind it.

Joint the flow and return connections to the boiler, replace the insulating material and screw on the cover plate and collar.

The boiler is now ready for connection to the hot water cylinder.
