Pressure regulators, rubber tubes and clips
CHECK that tubing is completely over the nozzles at each end of the
tubing and that it is held firmly in place by tube clips (See fig.9).
Check the expiry date and state of the rubber tube regularly. If it is
past its expiry date or has been damaged, replace it with one which
complies with the current regulations. Avoid bending or constricting
the rubber tube when the pressure regulator is connected to the gas
cylinder. This heater must be used with an approved Low Pressure
Regulator which complies with SAB S1237.
The regulator is required to reduce the pressure of the gas in the cylinder from about 700
kPa to about 2,8 kpa to operate the radiant - the heating panels).
Ventilation
USE ONLY IN A WELL VENTILATED ROOM
Adequate ventilation must be provided in rooms in which the heater is used. This ensures
removal of the products of combustion and allows the entry of replacement air. The fol-
lowing table shows the smallest size of room suitable for each heat setting and the dimen-
sions of the aperture which must be provided equally divided between high and low level,
according with the maximum, medium or minimum power.
Safety guard
The guard is to prevent risk of fire and no part of it should be permanently removed.
It does not give full protection for young children or the infirm.
