To check for a leak:
1. Make 2-3 oz. leak check solution (one part liquid
dishwashing detergent and three parts water).
2. Apply several drops of solution where regulator
connects to cylinder and to all hose and valve
connections.
3. Make sure all patio heater and light valves are OFF.
4. Turn cylinder valve ON.
If bubbles appear at any connection, there is a
leak.
1. Turn cylinder valve OFF.
2. If leak is at regulator/cylinder valve connection:
Disconnect, reconnect, and perform another leak check.
Apply the soapy solution to all hose and valve connections.
If you continue to see bubbles after several attempts, cylinder
valve is defective and should be returned to cylinder's place
of purchase.
3. If leak is at hose/regulator connection:
This part is defective and you should contact the customer
service department for replacement.
If NO bubbles appear at any connection, the connections are secure.
NOTE:
Whenever gas connections are loosened or removed, you must perform a complete leak test.
WARNING
Perform all leak tests outdoors.
Extinguish all open flames.
NEVER leak test when smoking.
Do not use the heater until all connections have been
leak tested and do not leak.
