LEAK TESTING
GENERALGENERAL
Although all gas connections on your Hestan Pizza Oven are leak tested at the factory prior to
shipment, a complete gas tightness check must be performed at the installation site due to possible
movement in shipment, or excessive pressure unknowingly being applied to parts of the unit.
Periodically check the whole system for leaks, or immediately check if the smell of gas is detected.
NOTE: For installations with hard-piped gas supply (not portable LP gas cylinder):
a) The outdoor cooking gas appliance and its individual shut-off valve must be disconnected from the
gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2
psi [3.5 kPa].
b) The outdoor cooking gas appliance must be isolated from the gas supply piping system by closing
its individual manual shut-off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi [3.5 kPa].
BEFORE TESTINGBEFORE TESTING
• Do not smoke while leak testing.
• Never leak test with an open flame.
• Make a soap solution of one part liquid detergent and one part water for leak testing purposes.
• Apply the solution to the gas fittings by using a spray bottle, a brush, or a sponge.
• For LP units, always check with a full LP cylinder.
TO TESTTO TEST
• Make sure the control valve is in the “OFF” position.
• Apply the soap solution described above to all fittings, hoses, etc.
• Turn the gas supply on.
• Check all connections from the supply line, or LP cylinder up to and including the manifold pipe
assembly and all connections to the burner.
• Soap bubbles will appear where a leak is present. If a leak is present, immediately turn off gas
supply, tighten any leaking fittings, turn the gas supply back on, and recheck.
• If you cannot stop a gas leak, turn off the gas supply and call the dealer where you purchased your
Pizza Oven.
• Do not use the Pizza Oven until all connections have been checked and do not leak.
IMPORTANT NOTE - ALWAYS CHECK FOR LEAKS AFTER EVERY LP CYLINDER CHANGE.IMPORTANT NOTE - ALWAYS CHECK FOR LEAKS AFTER EVERY LP CYLINDER CHANGE.
If a leak is present, or if there is evidence of excessive abrasion or wear, or the hose is cut, it must be
replaced before using the appliance. The hose and LP regulator are supplied as a complete assembly
and must be replaced together. Do not attempt to repair or replace the hose itself. Contact your
Hestan dealer for genuine replacement regulator P/N 014309.
Check all gas supply fittings for leaks before each use. It is handy to keep a spray bottle of soapy water
near the shut-off valve of the gas supply line. Spray all the fittings, hoses, etc. Bubbles indicate leaks.
