INSTALLATION

This heater makes use of an industrial
cylinder (9kg ALVA cylinder recommended)
with a 5/8" BSP thread; horizontall exit valve.
The Bullnose regulator supplied with the
heater tightens to the left hand side
(anti-clockwise). (Figure A)
If you have bought a new gas cylinder, the
cylinder needs to be purged (emptied out),
before it's first use. If it is not purged of air,
the heater will not work properly.
This should happen at the gas filling station
when you fill up the cylinder.
Always check this with your gas supplier.
