3.2 The Hamworthy Heating Ltd pipe work kit is designed to provide a complete primary circuit system for two and three
high stacked modules. Multiple stacked units can be connected together to provide large output arrays. See the following
pages for the size and number of modules that can be connected together. There is no pipe work kit option for single
boilers modules. The basic kit consists of a flow and return manifold to which can be fitted a combined low loss header
and dirt air separator, blanking flanges and a secondary manifold for three heating circuits.
•
The flow and return manifold is supplied with matched primary circuit pumps, isolating valves, gas manifold,
condensate drain and boiler safety relief valves. An automatic air vents is fitted to the top of the flow header and
the vertical flow and return manifold have connection points for flushing the system, plus drain and air bleed valves.
Flexible hoses connect the manifold to the flow and return ports on the boilers. Non return valves on the pump
supply prevent reverse flow through non firing modules.
•
The combined low loss header and dirt air separator has an adjustable support stand, sensor pockets in the flow
and return ports to control the mixed flow temperature, automatic air vent and drain valve for sludge removal. The
low loss header can be fitted to either the side of the flow and return pipe kit using the flanged pipes supplied.
•
Blanking flanges for the flow and return headers are provide with connection points for system safety relief valve in
the top flange and for an expansion vessel and/ or pressurisation unit in the lower flange.
•
The secondary circuit manifold allows for up to three separate heating circuits to be connected to the low loss
header. Fixing bolts and gaskets are provided with the manifold.
