Once connections are made, check for gas leaks at all joints.

Apply some gas leak detection solution to all gas fittings.

Bubbles are a sign of a leak. A combustible gas detector may

also be used to detect for leaks.

DANGER:

Explosion hazard!

▶ If you detect a gas leak, shut off the gas and ventilate the

room (open windows, doors). Tighten appropriate fittings

to stop leak. Turn the gas on and check again with a gas leak

detection solution. Never test for gas leaks using a match or

flame.
