Heater FAQ's: (continued...)
Q: What effects do separate burner chambers have on a heater?
A: On older heater models all three ceramic panels were mounted on a single
burner chamber. This allowed gas to "drift" to non-burning panels and escape
through it, allowing a slight increase in the gas smell and the wasting of fuel. The
new generation of heaters have 3 independent gas chambers. This prevents the
gas from floating to unused panels and thus reduces gas emission odours.
Q: How long is the heater supposed to burn for?
A: Refer to your instruction manual or technical data sticker on the back of your
heater. It will supply the g/h (grams per hour)consumption. Take the weight of
your gas cylinder e.g. (9kg = 9000g) and divide it by the g/h of your appliance.
The total you get will be the maximum amount of hours the appliance will be
able to burn for. (eg. 9000g / 265g/h = 34hrs at max)
Q: Can a cylinder be overfilled?
A: Yes. Cylinders should only be filled to 80% of the
cylinder capacity. This allows for gas expansion/
vaporization in the remaining 20% space.
If the cylinder is filled to the top, and then warmed, the
liquid will expand and the cylinder can burst open. This
is very dangerous and could cause serious damage and
probable injury. It should therefore be kept away from
extreme heat. Over-filling also causes issues with a gas
appliance not functioning correctly as liquid gas is being
pumped into the regulator, blocking it up.
Q: Can I see if the cylinder is over-filled?
A: The cylinder neck contains information on the weight of the cylinder. The
tare weight (TW) is the weight of an empty cylinder. Add the tare weight to the
capacity of the cylinder (e.g. TW – 9.4 and capacity 9 = 18.4kg) and weigh it. If
it exceeds the total weight, then your unit is over-filled. In such an instance, the
cylinder must be returned to the re-filling station. Users are no longer allowed to
purge the excess gas themselves.
A 9kg ALVA gas cylinder
GAS CYLINDER:
A 9kg ALVA gas cylinder with a 5/8 inch BSP left hand
thread is recommended.
This matches the supplied regulator.
Cylinders must be stored in an upright position, in a well
ventilated and damp free area and out of reach of children.
The cylinder must never be stored where temperatures can
reach or exceed 50'C.
DO NOT store the cylinder near open flames, pilot lights or
any other sources of ignition.
DO NOT SMOKE WHILE HANDLING THE CYLINDER.
