LEAK TESTING
Risk of burning or fire.
Serious burns to the skin or damage to property.
Do not use an open flame to check for leaks.
Leak testing before start-up, check the product connections for leaks.
1. Close all shut-off fittings on the gas appliance.
2. Slowly open the gas vapour or the gas cylinder valve(s).
3. Spray all connections with a foam producing substance according to EN 14291
(e.g. leak spray, item no. 02 601 00).
4. Bubbles will form in the foam producing substance if there are any leaks.
If more bubbles form, re-tighten the connections (see ASSEMBLY). If you cannot stop the
leaks, you must not use the product.
START-UP
After the product has been ASSEMBLED and LEAK TESTING has been carried out
successfully, it is immediately ready for operation.
If you open the gas vapour or the gas cylinder valve too quickly, this can result in
a short-term pressure increase that triggers the over-pressure safety device S2SR.
OPERATION
The product requires no operation while it is running.
