UNPACKING and ASSEMBLY
To safeguard against damage in transit, MOL modulating burners may be supplied in partly assembled
form in one of three alternative modes:
Mode 1: The complete burner unit fully assembled.
Mode 2: Burner body complete with control panel. Combustion head hinged extension and flame tube
assembly.
To assemble the burner:
Assembly of the burner can be completed after fitting the hinged extension/flame tube
assembly to the appliance.
Alternatively, fit the extension/flame tube assembly to the burner body using the four nuts and
washers provided.
The pumping unit is supplied as a separate component to modes 1 and 2 and is inclusive of flexible pipes
to make all the necessary oil connections.
Mode 3: On request, MOL modulating burners can be supplied in a fully assembled compact
configuration. These burners include the oil pumping and conditioning unit mounted beneath
the burner body and are pre-piped, requiring only the connection of fuel and electrical
supplies to complete the installation. The suitability for installation of compact modulating
burners should be referred to the appliance manufacturer as the addition of the oil pumping
unit adds extra weight to the appliance frontplate.
