1.0 DESIGN1.3 SYSTEM DETAILSHeating SystemMethod of connecting two BoilerMates to one heat source.If the primary flow and return pipework continuously rises from the boiler to theBoilerMate the recommended method for connecting two BoilerMates to one heatsource is to fit the BoilerMates as normal but to provide a single check valve on thebranch immediately after each primary pump.The heating and hot water from each appliance must serve separate zones/bathroomswithin the property.The electrical supplies from each appliance to the boiler will need twinning so thatthe boiler will operate on a call from either/both appliances.Both primary pumps and the primary pipework sizes should be checked to ensurethat they are adequate for the system that has been installed.If the primary pipework dips or the boiler is located above the BoilerMatea single F & E cistern with a cold feed and open vent piped to the cisternshould be used.This arrangement is not suitable for BoilerMate appliances fitted with Switch.If it is proposed to use this arrangement please advise Gledhill at the time of order,Gledhill will then supply a suitable vent assembly for fitting on the safety/open ventconnection and a blank for the cold feed connection of each BoilerMate 2000, inlieu of the F & E cistern normally provided.If the boiler is a long way from the BoilerMate the resistance should be checkedto ensure the pumps cannot produce a negative pressure in the BoilerMateappliance.The single F & E cistern will need to be provided, (by the installer) and be suitablefor the size of the total system installed.For further details please ring the Gledhill Technical helpline.Page 16
