(A)
General
1.
The user should read these instructions thoroughly before attempting to operate
the Hotbox CO
2
Generator and ensure there is no unauthorised interference with
the appliance by persons not competent to do so.
2.
Ensure that adequate ventilation is provided for the generator, since inadequate
ventilation will mean incomplete combustion, resulting in unburnt or partially
burnt gases. This is particularly important in areas where more than 1000ppm of
CO
2
is being used.
NOTE: UNBURNT GAS CAN BE TOXIC TO PLANTS
THE GENERATOR NEEDS A CONTINUOUS SUPPLY OF OXYGEN TO
ENSURE THAT ALL GAS IS COMPLETELY BURNT.
The ventilation you provide (minimum 3sq.in – 10cm
2
) should be installed in such
a way to ensure that the fresh air with its supply of oxygen can easily reach the
burner. This is particularly necessary in a polythene tunnel where the generator
can be several feet from the doors where the only natural ventilation exists.
One method of providing the required fresh air is to install a 3”(15cm) diameter
plastic pipe (or similar) from the outside to the base of the generator and allow for
the exhaust of burnt gas by fitting a piece of Rokolene or similar material in or
above the doors at the end of the greenhouse (3sq.in – 10cm
2
)
3.
Ensure the Hotbox CO2 Generator is fixed in a stable position, ideally on a solid
base such as a paving slab.
4.
Check that there is no combustable material in the area above or around the
generator. Remember that the heater casing becomes hot when in use.
