How To Replace Safe-T-Alert RV Propane Gas Detector?

Propane gas detectors are crucial safety devices in RVs and trailers. The explosive gas can leak from appliances and fittings and lead to dangerous accumulation inside the living space. Long-term inhalation exposure poses serious health risks. These detectors alert occupants to hazardous concentrations of propane to allow quick evacuation and ventilation. Carbon monoxide (CO) is another silent killer. Faulty combustion from appliances like furnaces, generators, and stoves produces this poisonous gas. Prolonged exposure causes debilitating symptoms and even death. Combination propane and CO detectors provide comprehensive monitoring.

Replacing aging or malfunctioning units ensures continuous protection. Most detectors have limited 5-7 year lifespans. Technological improvements warrant upgrading older models as well. This guide covers the necessary steps for installing new detectors in your RV or trailer. Simply put, you need to identify and replace an old RV gas detector, prepare wiring and power down, remove the old unit safely, install and mount the replacement properly, restore power and test the alarm, and perform regular checks to verify functionality.

Spotting the Issue

Flashing LED lights and beeping signals indicate a detector requires replacement. Consult the user manual for your specific model. Generally, repeated short beeps every 30-60 seconds signify low battery or end of operational life. A continuous solid tone means a dangerous gas level is detected.

Pressing the test button triggers the alarm. If no sound occurs, the detector likely malfunctioned. However, silence does not guarantee functionality. Only by controlling gas levels during a test can you verify working alert systems.

Ready for Replacement

Propane and CO detectors come in various shapes and sizes. RV manufacturers also relocated units over the years. Carefully note the existing detector’s dimensions, wiring, and mounting location. This ensures an optimal new fit. Purchase well before the expiration date.

Common hand tools like screwdrivers, wire strippers, voltmeter, and wire nuts suffice for most installs. A Dremel rotary tool allows for enlarging or modifying openings precisely. Always wear eye protection.

Shut off propane at the tank and cylinder connection before beginning. Open doors and windows to ventilate the interior space. Consider temporary CO monitoring as some generators emit the gas when running.

Taking Out the Old Detector

Access the detector’s rear wiring by unscrewing the mounting screws or sliding out the unit. Do not cut wires until ready for replacement! Label wires as positive and negative. Note any specific color coding.

Disconnect wires safely using wire cutters or needle nose pliers. Twist copper ends together to prevent fraying. If reusing existing wiring, install crimp connectors to adapt to new unit terminals.

Carefully pry the detector free using a flat screwdriver. Clean dust and debris from the mounting area. Cover openings to prevent contamination until the new installation.

Setting Up the New Replacement

Choose a location that allows easy access for testing while avoiding kitchen areas with excessive grease. Ensure suitable wire length to reach terminals. Placement near windows improves ventilation.

Carefully cut an opening for the new detector using the proper size hole saw bit for the Dremel. Allow a 1/8″ gap all around. Prevent debris from falling into wall void. Mounting to exterior walls provides optimum airflow.

Strip 1/4″ insulation from replacement wires. Attach the source or positive wire (typically red) to the detector’s right terminal. The negative or ground wire connects to the left. Secure with clamping wire nuts and insulated crimp connectors.

Insert the detector and fasten the mounting screws. Do not over-tighten. Restore power and propane supply. Verify the green operational light flashes and test alarm sounds. Slide the outer decorative cover into place if equipped.

Apply the manufacturer expiration sticker with the new five or seven-year replacement date. Note this in your appliance records also. Perform monthly tests to ensure proper functioning.

Prioritize Safety First

Follow the manufacturer’s instructions if the alarm sounds. Evacuate the RV immediately and shut off propane valves until the source is found and resolved. Proper detector operation saves lives.

Only use soap and water when cleaning the outer housing. Cleaners and solvents can damage sensors. Avoid painting over detectors. Always replace units past their operational life.

Installing a new propane and CO detector keeps your RV safe for remote camping and road-tripping. Following proper procedures and testing ensures your system provides alerts when you need them most.

Troubleshooting Common Issues

Even when carefully installed, problems can arise with RV gas detectors. Here are some troubleshooting tips for common situations –

Unit fails to power on: Check wiring connections, test with a voltmeter, and inspect fuses/breakers. Ensure propane is on.

No audible alarm during testing: Gently clean contacts with alcohol. Test 9v battery if applicable. Locate the built-in horn.

Frequent false alarms: Ensure the mounting location avoids cooking gases, smoke, and cleaners. Check propane lines for leaks. May need sensitivity adjustment.

Green operational light not flashing: Reset by removing power for 30 seconds. If persists, the unit is likely defective.

Beeping with no obvious issue: Replace the battery if present. Check propane levels. May be time for replacement.

Loose mounting: Tighten screws being careful not to damage plastic housing. Use washers if needed for stability.

If problems persist after troubleshooting, replacement may be necessary for reliability. Only functioning detectors provide adequate protection.
