(1) The sizes shown allow for the unvented store expansion vessel to be fitted above the appliance in the case of the 180 and
210 models, but assume that the optional primary sealed system kit will be fitted elsewhere. The dimensions for the 240
model assume both the unvented store and primary expansion vessels will be fitted elsewhere due to the height of the
appliance itself. Clear access 650 deep will be required in front of the whole of the appliance for future maintenance.
(2) Supplied loose - To be fitted by installer in a suitably accessible location.
(3) Temperature is automatically controlled by the controller sensors S1/S2.
(4) Not adjustable - Manual reset type.
(5) Temperature is automatically controlled by the controller sensor therefore should not be set lower than 65
