Your propane regulator controls the strength and flow of propane vapor in your residential or commercial propane systems and appliances. It plays an important role in making your appliances, including grills, heaters, stoves and ovens, operate safely and at optimal performance. Propane gas naturally flows at a high pressure. The regulator monitors and reduces the gas to the consistent, low pressure required for safe usage. Since propane gas is dangerous, regularly check your regulator and immediately replace if it is not working correctly.
Things You'll Need
- Flat-head screwdriver
- Propane regulator
- Dish soap
- Tank hood or dome
Pull on the work gloves and turn the knob on top of the propane tank clockwise to the "off" position. Tighten the tank pressure knob to confirm no gas is flowing to the appliance or system. If the tank is connected to a grill, flip on and off one or more of the burners to empty any residual propane gas inside the lines.
Turn the old regulator to left, using the pliers, to loosen and remove it from the regulator connection on the propane tank.
Remove the other end of the regulator from the appliance's propane hose or line by turning it to the left with the wrench. Put the old regulator aside.
Remove the regulator safety from the new regulator with a flat-head screwdriver.
Twist the thermostat on the new regulator one full rotation to the right. Make sure the thermostat is tightly secured.
Put the regulator on the propane tank regulator connection and tighten to the right with the wrench.
Turn the regulator vent downward and confirm it is a minimum of 3 feet from any building opening, if necessary. Pointing the vent downward prevents dirt and other debris from getting inside and causing problems with your regulator.
Carefully turn the propane tank on. Check for leaks. You might hear a hissing noise or smell gas if there is a leak. Mix a small amount of water and dish soap in a bowl. Brush the mixture on the regulator connection at the tank. If bubbles form, there is a leak. Turn off the propane tank, tighten the connection and repeat until resolved.
Place the tank hood or dome over the propane regulator to protect it from damage. Regulator damage can result in a propane leak, causing injury to you and others around you.
