How to install a gas alarm on a boat
Installing a gas alarm on a boat is a sensible precaution to protect against leaking vapours from butane, propane and petrol supplies – all of which are heavier than air and can collect in large quantities unnoticed.
Because of this, it’s important to get your gas alarm installation right. In this guide we’ll look at some of the most crucial elements to get right when installing a gas alarm on a boat.
Always shut off the power supply before beginning installation.
Locate the gas alarm’s power supply on the boat’s master switch circuit, to ensure it is always turned on when the vessel’s power is on.
Position the main unit where it is protected from bad weather, but where the ventilation holes are open to good air flow.
You should ensure you can see the status LEDs and test the audible alarm to make certain that it cannot be missed.
Because the hazardous vapours involved in boat gas leaks are heavier than air, it is essential to position the gas sensors as low down as possible.
Place them close to gas appliances for faster detection in the event of a leak, either just above the floor or under the floorboards.
Make sure the gas sensors will stay dry at all times and consider access in the future in case the sensors need to be serviced or replaced.
Follow the wiring diagram supplied with your gas alarm. There are connectors for the power supply, one or more gas sensors, and the solenoid shut-off valve to interrupt the gas supply if a leak is detected.
Once installation is complete and all the units are securely wall-mounted using the fixing holes, it’s time for the first power-on and self-test.
Your gas alarm should cycle through testing its LEDs and alarm sounder. The sounder will usually stop after about 30 seconds, and if it does not, this could be an indication that the alarm has already been triggered.
After the initial self-test, which may take several minutes after the audible alarm stops, you should be left with a green LED to indicate power on and situation nominal – giving you peace of mind that your vessel is protected against any gas leaks now and in the future.
