Draining the Liquid Gas
WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
- At low temperature there is a risk that not all liquid gas will be removed from the tank during the draining operation.
- Reason: Liquid petroleum gas is a mixture of gases with different boiling points.
- There are various methods of tank drainage:
- Pump out the liquid gas with subsequent controlled burning off of the gas phase.
- Drain the liquid gas with subsequent blow-off of the gas phase.
- Controlled burn of the liquid gas via a torch.
- In all methods, a safety zone must be set up which may vary. The place for erection of the safety zone must be selected so that no gas can penetrate remote buildings, e.g. via open windows and doors. The place must also be easily accessible and well ventilated.
- When draining liquid gas, ensure that the place has a safety zone of at least 10 m (33 ft) radius which may be extended if necessary.
- The safety zone must be marked off in a manner which is clear to everyone. The place must have no recesses or depressions as liquid gas can collect here.
- The draining procedures are to be found under "Engine Controls/Fuel".
