Fitting the Boiler
When the boiler is to be used on a system with gravity
D.H.W. it is necessary to disconnect the overheat
thermostat by removing the wire with the black sleeve
and attaching it to the wire with the red sleeve as
shown.
The overheat thermostat is now by-passed and will
allow the appliance to perform satisfactorily on gravity
circulation.
NOTE: Even though the overheat thermostat is not
operational, it must not be removed from the pocket in
the heat exchanger except during servicing.
Lift boiler and engage centrally the back bottom edge
into the hook bracket on the mounting plate.
Rotate the boiler back to the mounting plate to
engage two studs and spring latch.
Fit the two wing nuts. Tighten to compress rear
flue seal.
