HEATER OPERATION WITHOUT PEOPLE IN THE ROOM

Ensure that sufficient air is available via windows and doors for complete

combustion. The heated volume (m

)/ heat output (kW) ratio must be at least

10:1, and personnel should not stay permanently in the heated room.

HEATER OPERATION WITH PEOPLE REMAINING IN THE ROOM

If people are to remain in the room for any length of time, the heated volume

) /heat output (kW) must be at least 30:1. Air circulation must be ensured

through windows and doors or permanent openings near the floor and

ceilings, whose total open area (m

) is at least 0.003 times the total heat

output (kW).

OPERATION

In normal operation, operating the ON/OFF switch will illuminate the red LED

and the green and orange warning lights. After two minutes, when the fuel

warming operation is completed, the orange warning light and the red LED

go out and the motor starts.

The following table shows the main operating phases.

1. Check that there is diesel in the fuel tank.

2. Switch the ON/OFF switch to ON.

• The green and orange LEDs will light up for the duration of the pre-heating

time.

followed by a ‘pre-purge’ time of about 30 seconds.
