Please follow below procedures for small bubble test.
- Mix a small amount of dish soap into a large container of water;
- Make sure the gas is on;
- Using a cloth or sponge, wipe down the suspected area;
- If you see bubbles forming, that means you have a leak. Please disconnected the gas and check the
condition of the connection. INSTALLATION AND SERVICES MUST BE PERFORMED BY A QUALIFIED
INSTALLER.
Step 5
Safety and Performance Check after NG Conversion:
1. All the distance between electrode needle and burner orifice should be around 3 –5 mm (0.11 –0.19
inch)
2. Check all gas connection with Bubble test (detailed procedures please follow Step 4 –4)
3. Check the regulator gas pressure (4- inch water column for NG)
4. Check the burner BTU for each burner (BTU is not changing after NG Conversion)
5. Check the flame condition (See below picture)
-Visually check the burner flames. They should be blue or slightly yellow.
-Check and clean all burners/ venturi tubes for insects and insect nests. A clogged tube can lead to
fire hazard under the outdoor cooking grill.
