3.6 Electrical Supply

A permanent 230 V, 50 Hz, 1 Ø is required on

models 15 to 30 and 400 V, 50 Hz, 3 Ø and neutral

required on models 40 to 100 (special version MGB

and MOB 040 and 050 models are available as belt

drive). The heater also requires suitable energy

controls in accordance with Page 27, Section 9.

ON/OFF control, temperature control, time control,

and frost protection are available as a remote

control, which needs to be site wired for proper

operation of the heater. Alternatively, any remote

energy controls may be used which must be wired in

accordance with Page 28, Section 9.3 through Page

39, Section 9.14.

3.7 Flue

Choose heater siting to allow for the proper location

of the flue. Each heater must be fitted with an

individual and correctly sized sealed flue system.

See Page 17, Section 6.

No other appliance may be connected to the flue.

For room sealed installation, the air intake must be

the same size sealed system and the flue/air intake

must terminate at an approved concentric wall or

roof terminal.
