Range of wall mounted, gas-fired condensing combination boilers providing domestic hot water via a plate heat exchanger and pressurised central heating system incorporating an expansion vessel, pressure relief valve set at 3.0 bar and flow regulators. The inlets to both domestic hot water and primary circuits are controlled via screwdriver operated angled spherical valve. The primary circuit can be filled via a built in CAB device, that has been verified by test (suitable for backflow protection against Fluid Category 3). Primary circuit: Maximum working pressure 2.5 bar. Maximum operating temperature 80°C. Secondary circuit: Maximum working pressure 10.0 bar. Maximum operating temperature 60°C.

Section:

1465 Heaters

Section Subtitle:

Combination boilers and Water Jacketed Tube heaters. Low volume water content. Heat retained in water heaters will cause expansion of water after closure of draw-off taps and valves. Provision for expansion of water must be made to accommodate excess pressure within the system. Particular care is required where check valves are positioned, or loose jumper valves are thought to be upstream of the heater.

WRAS Approval Number:

2402803

Note:

The discharge from the relief outlet port of the CAB device must be made via a type AA, AB or AD air gap, or in accordance with EN 1717. Claims of flow rate are made by the manufacturer and not considered part of the listing.
