gas cylinder.

Tighten the connection and retry the leak test.

If you are unsure or if you cannot tighten the
connection, place the cylinder outside in a cool,
well-ventilated area and contact ALVA on 086 100

A leak between the heater and cylinder can lead
to a high pressure fire, which is very dangerous
and can result in extensive injury or even death.
