ALPHA700
4.0 specification
for Alpha700
5.0 delivery
The three pass heat exchanger is constructed using high carbon content corrosion resistant cast iron
sections with turbo rotational flue passes and polygonal profile combustion chamber.
The assembled body is connected together using biconical nipples and full length tie rods. Gas tight
sealing of the sections, one to another, is achieved using ceramic fibre rope bedded into channels in the
casting faces.
The rear of the combustion chamber includes an anchored ceramic target wall. The combustion
chamber is fully water cooled and is spaced generously above floor level to ensure low boiler house floor
temperatures. The boiler is suitable for a maximum flow temperature of 95°C and a maximum working
pressure of 5.5 bar.
combustion chamber door
The combustion chamber door covers the entire front of the boiler body, providing uncompromised
access to the combustion chamber and horizontal flueways, allowing total front cleaning with the robust
cleaning tools provided. The door is hinged on both left and right hand sides giving freedom of choice for
handed opening without the need to move hinge positions. The door is heavily insulated with dense
ceramic fibre panels which reduces heat loss and thermal inertia.
insulation
The boiler body is insulated on all faces with a dense fibre-backed insulating blanket of 100mm
thickness.
casing
Each boiler is provided with a high quality rigidly attached stove enamelled casing.
control panel
Each boiler is supplied with a fully pre-wired top mounted control pod which incorporates high and low
fire control thermostats, manual reset high limit thermostat, water temperature thermometer, burner
on/off switch, pump on/off switch, high limit thermostat test button, high and low fire hours run counters,
fascia mounted fuse holder and lamps to indicate low fire, high fire, power on, high limit trip and burner
lockout. As an option, volt free contacts may be included to relay status information to a BMS or similar
remote monitoring panels.
