GAS LEAKAGE INSPECTION
After the pipeline connection is done, use a leakage inspection device to carefully check
if there is any leakage at the joints. This is an important step to ensure the quality of
installation. Once a leak is detected, proper action should be taken immediately.
1. For good drainage, the drain hose should be angled downwards.
2. Do not pull on or bend the drain hose or flood its end with water.
3. When the long drainage hose passes through indoor areas, it should be wrapped in
insulation.
