Test all gas piping and connections

for leaks after installation or servicing. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

2.Connect POL fitting on hose/regulator assembly to propane tank(s). Turn POL fitting counterclockwise into threads on tank. Tighten firmly using 7/8" wrench.

IMPORTANT: Position regulator so that hose leaving the regulator is in a horizontal position (See Figure 4). This places the regulator vent in the proper position to protect it from the weather.
