GAS CONNECTION
LEAK TESTING
GENERAL
EN
Although all gas connections on your Hestan appliance 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. Immediately check if the smell of gas is detected. Leak testing of the appliance shall be
conducted according to these instructions:
BEFORE 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 and flex hose by using a spray bottle or a brush.
TO TEST
•
Make sure all control knobs are in the "OFF" position.
•
Apply the soap solution to all fittings and flex hose.
•
Turn the gas supply on.
•
Check all connections from the supply line up to regulator connection at the rear of the
appliance.
•
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 appliance.
•
Do not use the appliance until all connections have been checked and do not leak.
TESTING APPLIANCE REGULATOR
When checking appliance regulator function, make certain that the correct pressure is supplied to
the regulator. For natural gas supply, 6 - 14 inches W.C. [1.49 - 3.48 kPa]. If converted to LP gas, 11
- 14 inches W.C. [2.43 - 3.48 kPa].
To pressure test the regulator, select one of the side burners and connect to the orifice port, as
follows:
PRESSURE TEST PROCEDURE
1) Remove grate and burner cap (A).
2) Remove gas spreader (B).
3) Temporarily remove the orifice (C).
Note - for the 36" unit's stacked burner, you will use the center (simmer) orifice, and set the
knob to SIM so that the main orifice does not flow.
4) Connect the pressure test gauge into the port that you removed the orifice from. (M6 x 0.75)
