220-240 Vac to 120 Vac, 10 VA minimum stepdown transformer (not provided) must be used to drive the shutter. The transformer is NOT
needed for UV flame sensor models C7061A1020, C7061A1079 and C7061F1003 (combined with R7861-series flame amplifiers), which
have an internal selectable terminal block to connect 230V shutter output from EC7895 models directly.
