How to install?
Natural gas is comprised of methane gas that is lighter than air. In case of gas leakage; gas rises towards ceiling and accumulates in areas near ceiling. Therefore, for natural gas, the detector shall be located in a position of 30cm under the ceiling and 1.5-4 meter(s) away from gas supply.
LPG is comprised of mixture of propane and butane that is heavier than air. In case of gas leakage, LPG falls down to ground. Therefore, for LPG, the detector shall be located in a position of 30 cm above the floor and 1.5-4 meter(s) away from gas supply.

I recently purchased the YK-818 55 Natural Gas Detector Leak Alarm Sensor and I am very impressed with its performance. The device has a sleek design and is easy to install. It is equipped with a digital display that accurately shows the concentration of natural gas in the air, and the voice prompt feature is a great addition that provides added safety.The strobe light warning is also very effective and provides a visual alert in case of a gas leak. The device has a wide range of detection for butane and methane gases and it is very sensitive, providing timely alerts to potential hazards.The YK-818 55 Natural Gas Detector Leak Alarm Sensor is an excellent investment for anyone who wants to ensure the safety of their home or workplace. It is a reliable device that has exceeded my expectations and I highly recommend it to anyone looking for a high-quality gas leak detector.

I got this because I have propane gas logs. I have an old house so I wanted to be sure I had a good alarm if/when needed.This one plugs in and the 6 page manual tells you exactly where to mount it for natural gas or LPG. It’s mounted 30 cm (11.8 inches) from the ceiling (natural gas) or 30 cm from the floor for propane. It comes with screws for a permanent mount and also a double sided sticky pad. The warm up is 3 minutes, so you will know that it’s working. Audible prompts let you know what stage it’s in. It is a loud alarm and flashes a bright red when the Test button is pressed. The same red flash that would indicate a gas leak. Otherwise, there is a green light on the front that lets you know it’s on. I feel comfortable that I have this as an alarm to ‘smell’ the gas if I’m not aware of it.

Propane is used for cooking, central heat, a hearth stove and four emergency gas lamps in my home so several gas detectors are a necessity. This gas detector has several good features:1. Voice prompt in English, press the test button during the setup period and it switches to Chinese, press again and it’s back to English.2. 6 feet of power cord means that there’s sufficient length in most installations to mount near the ceiling for natural gas or near the floor for propane. The detector is not mounted directly on the receptacle and therefore does not block the second outlet of a duplex receptacle.3. A detachable mounting plate makes mounting easier as the screw(s) can be installed right through the plate before attaching the detector. Double stick tape along with screws and drywall anchors are supplied.4. Battery backup (battery not included, user needs to provide a 9 volt battery) is a great feature as gas use continues during power failures and additional gas appliances are sometimes brought online during these periods. It’s very important to have a battery backup for this reason.The only drawbacks that I’ve seen so far are that the service life (typically 3 to 5 years) is not specified in the documentation and the sticker on the back had to be peeled back a little to access the battery compartment.

Getting up there in years, I seem to be becoming more safety minded than during my younger years. Although we of course have smoke detectors in our house and due to having a gas fired furnace and hot water heater, we also have carbon monoxide detectors. Recently I decided to also install this combustible gas sensor/alarm. In my rush to order, I missed the fact that this detector needs to be plugged in to a 110V outlet as well as needing a 9V battery. I had thought it was only battery operated like some of my smoke detectors. As I plan to install this in my basement utility room where the furnace and hot water heater is (i.e., all my NG appliances), I’ll need to add another outlet in, but that’s not a big deal. The sensor/alarm seems to be well constructed. The provided written instructions don’t even mention the 9V battery at all. I assume that it is for backup during electric outages as I plugged the sensor/alarm in and ran a test. Without the battery, everything lit up and it began its warmup cycle. I then used the test button and the alarm sounded as it should. I would say that it could be a little louder so people could hear if from anywhere in the house, but I guess at night when everything else is quiet, this may work okay. Some of my home security cameras also monitor for alarm sounds, so I will make sure that at least one of them will hear the gas alarm and notify me wherever I am.

This is a simple detector for combustible gases. This unit comes with a standard 110 volt cable so it does have to be plugged in at all times, but it does have a 9V battery backup. Installation depends on what kind of gas you are looking to detect. The instructions say to mount it high up for lighter than air gases like Natural Gas or lower to the floor for heavier than air gases like propane. I plugged it in and it has a voice announcement that it’s warming up. There is a 3 minute count down and then it loudly announces that it’s all ready. You can press the test button on the front to test the siren which seemed adequate. Since I wanted to see if it would detect a combustible gas, I put the detector inside my gas grill and turned on a few burners without lighting them. I watched for about a minute as the number on the display go from 0 to 1, then it kept climbing until the alarm went off. Moving the detector away from the gas immediately turned off the alarm. It certainly makes a lot of noise but I didn’t think it was quite as loud as my smoke detectors. Something to keep in mind.So it will detect propane. I plan to permanently install it near my gas appliances in the basement. The kit came with a mounting bracket, screws with a couple of plastic wall anchors, and a piece of double stick foam in case you can’t use the screws. The cord is about 6 feet long so it will have to be somewhere relatively close to an existing outlet.

When you get your gas direct from the ground from a gas well, your gas is not odorized like “city gas” This at times makes it hard to know when you have a leak. This alarm gives me a piece of mind knowing it can detect the gas even if I can’t always smell it.I tested it out by leaving my stove on without a flame and within a short time it alarmed. Long before the level of gas would have been a danger.This is the perfect product for those that live with natural gas without the odor additive.

This device is a must-have if you have gas lines. I need to get myself another one, Unfortunately, I didn’t get to enjoy it for long, since it seems that it magically disappears from my counter. I got people who came in and out repairing a faucet and pest control. Anyhow, while last in my possession, I can tell you that I learn to appreciate it. Having one of these can make a difference in people’s safety. Especially in the wintertime. Please get one of these devices if you have children living with you. Gas is another silent killer.Is small like your phone’s length but thicker. Works with a battery 9V battery, yes, that is not very convenient. I wish it was rechargeable, so no more batteries will end up in the landfill.It is small but is super loud if the alarm goes off. The device itself seems to be good quality and seems to function properly without any problems for the time I have had it. It comes with instructions. This is an excellent value money-wise. This little device will make an excellent gift for any occasion, especially for housewarming parties. I guess for travel too, you may never know nowadays the things you hear in the news.As I said, a must-have. I highly recommend it!

So far, the gas sensor has been working without issues. I bought this particular gas sensor because of the battery (9v) backup. I did test it with a butane? (fireplace/grill igniter) gas source and it did go off. It currently resides at the top of our gas furnace closet.
