Why the Oasis gas heater does not light and goes out

Imagine this: it’s a chilly winter’s evening, and you can’t wait to curl up with your Oasis gas heater in your house. To your dismay, though, it won’t light up correctly, leaving you in the dark. It’s annoying, isn’t it? You’re not alone if this situation has happened to you. A non-lighting Oasis gas heater is a common problem that many homeowners face with their gas heaters. Let’s investigate the potential causes of this and look into potential fixes.

First and foremost, it’s critical to comprehend the workings of a gas heater. The Oasis model and other gas heaters depend on the combustion of fuel (usually natural gas or propane) and ignition to generate heat. Gas enters the combustion chamber of your heater when it is turned on, mixing with air. The gas-air mixture is then ignited by a spark or pilot light, producing the heat that warms your house. However, your heater may not light at all or may extinguish quickly after lighting if any part of this process fails, such as an ignition system that isn’t working properly or an inadequate gas flow.

An ignition system problem is a common cause of an Oasis gas heater that won’t light. The pilot light, also known as the igniter, and the thermocouple are two of the parts that make up the ignition system. The pilot light may not light or stay lit for a variety of reasons, such as a dirty or broken part, incorrect positioning, or insufficient gas flow. Similar to this, a broken thermocouple—a safety mechanism that determines whether the pilot light is lit—may result in the gas supply cutting off, which would keep the heater from continuing to burn.

Your Oasis gas heater’s upkeep and cleanliness are additional factors to take into account. Like any appliance, gas heaters need to be maintained on a regular basis to function at their best. Dust, dirt, and other debris can build up in the heater’s burner assembly, air vents, and other important components over time, preventing airflow and hindering ignition. In addition, problems with ignition and general efficiency can result from skipping regular maintenance chores like cleaning the pilot light or replacing air filters.

Moreover, the issue of an Oasis gas heater that won’t light can also be caused by outside variables like inadequate ventilation or low gas pressure. Poor combustion brought on by inadequate ventilation may cause the pilot light to flicker or go out. Similar to this, if the gas supply to your house is erratic or inconsistent, your heater might find it difficult to keep a steady flame, which could result in frequent shutdowns.

In conclusion, diagnosing and resolving the root causes of a non-lighting Oasis gas heater necessitates a methodical approach. You can reduce your chance of an ignition failure and continue to have heat during the winter by being aware of the basic operations of your heater, giving it routine maintenance, making sure the gas supply and ventilation are adequate, and maintaining basic understanding of how it operates.

In our exploration of the common issue with Oasis gas heaters failing to ignite and staying lit, several factors emerge as potential culprits. Firstly, improper gas flow or pressure could be at fault, hindering the combustion process. Secondly, a malfunctioning thermocouple, which senses heat and maintains the gas valve open, might be failing to do its job effectively. Additionally, a clogged pilot light or burner assembly could obstruct the flow of gas, leading to ignition failures. Furthermore, issues with the ignition system itself, such as a faulty igniter or control module, could prevent the heater from lighting up consistently. Lastly, inadequate ventilation or a lack of proper air circulation around the heater could also contribute to ignition problems. Understanding these potential causes can guide troubleshooting efforts and help restore efficient operation to Oasis gas heaters.

Peculiarities of Oasis gas boilers operation

The kitchen or another non-residential room with heating is where the water heater is situated. The installation is completed in compliance with the gasification project and the technical requirements of the gas supply company.

It is guaranteed to fulfill the subsequent requirements:

• The burner shall be connected to a smoke exhaust system having the necessary geometric size and draught to enable it to burn steadily;
• it is not allowed to place an open fire or powerful sources of heat energy in front of the column;
• before starting the installation, the owner of the premises must obtain all permits and technical conditions from the gas service for the installation of the equipment;
• installation, adjustment and start-up of the column should be carried out by certified organizations and representatives of the gas supply company in order to avoid problems with obtaining permission to use the column and with the warranty obligations of the manufacturer;
• the unit should be installed on a brick or concrete wall covered with non-combustible materials, the protective layer should extend around the perimeter of the housing by at least 15 cm;
• the column is fixed on the factory-made brackets supplied in the kit.

Crucial! Every control and shut-off fitting in the gas and water pipelines needs to be conveniently located.

Main causes of malfunctions and methods of their elimination

Depending on proper selection, installation, and operating conditions, all gas equipment used to heat water will eventually break down. Water heaters are no different. One of the most frequent malfunctions is when the gas heater Oasis lights up and shuts off. There are various causes for this, so it’s important to know what to look for in each situation.

When a potentially dangerous sign of a malfunction appears, like when the unit smells like gas when it first starts up, you should quickly turn off the tap in front of the heater, ventilate the space, and call a gas service representative.

Kindly take note! Oasis has distinct technical features, so it will be important to follow its plan before getting rid of it.

Incorrect pipe connection

When the device is installed incorrectly and the hot and cold water inputs and outputs are mixed up, it can lead to malfunctions such as gas flow water heater Oasis malfunctions. Oasis units function by connecting the cold water spigot to a water block that has a mechanism installed to change the liquid flow’s pressure and speed. In addition, a water drainage unit and safety valve are included for overpressure relief and repair purposes.

The copper heat exchanger, which is the next significant node in the medium’s movement and is situated above the collector, is made up of a ribbed pipe that is curved. Heat from the flue gas exhaust is captured by the design and is transferred to the flowing water through the water unit. The diverter spigot allows the heated water’s output to reach the water tap. In order to prevent the unit from overheating, a temperature sensor is mounted on the spigot. Consequently, there won’t be any water circulation if the water medium’s inlet and outlet are mixed up.

Powerful extraction

When the discharge is determined by the height of the chimney and the air is drawn from the room where the heater is located, this failure is particularly hazardous for devices that operate with open fire chambers through natural circulation. When a powerful exhaust system is installed in the house across from the gas heater, the exhaust hood draws in the flue gases from the furnace space instead of them entering the atmosphere through the chimney.

More details! A decrease in discharge, the flame moving away from the burner, the activation of the flame sensor, and an emergency shutdown result from this. Until the exhaust units are turned off, it cannot turn on. It is not permitted to connect them when the Oasis equipment is operating in order to avoid this kind of failure.

The chimney channel is clogged

When the gas heater Oasis fails to ignite due to a lack of draught, the cause is typically soot buildup in the heat exchanger and smoke ventilation system, clogging the fin tubes. A sensor measures this, and if the results are low, the gas supply to the appliance is cut off as part of a safety feature.

The heater won’t catch fire in these circumstances. Draughts are simple to check; just hold a lit candle near the ventilation system to see if the flames move toward the channel. If not, cleaning the gas ducts and interior heating surfaces of soot deposits will be required.

Poor ventilation in the space may be the next reason for a bad draft. These days, plastic windows are "not friendly with ventilation" in many apartments; the unit only functions in these rooms when the window is open. It will be essential to install a specific supply valve to guarantee adequate air circulation in the room in order to prevent this kind of failure.

Low water or gas pressure in the system

It is not uncommon for the water assembly to operate incorrectly. This is a result of the unit’s design. The pressure increases as heated water enters, acting to bend the diaphragm and transfer pressure to the gas valve stem. As it moves and exerts pressure on the spring valve, the control module’s power supply is turned on.

More details! It is evident that the device will not turn on if this system malfunctions. There may be multiple causes of failure due to the intricate workings of the water unit. Since the water unit and gas module are one single construction, they are disassembled together.

The diaphragm, also known as the "frog," stretches during operation and results in similar equipment failures. It needs to be replaced because of this deformation because it prevents the equipment from turning off. You can perform the easy task of repair with your own hands. This unit is tiny, and only four screws need to be unscrewed in order to obtain the "frog."

Clogging of the heat exchanger

In the event that the column displays any of the following failure indicators, boiler repair will be necessary:

• low heating water pressure at the unit outlet;
• low water temperature from the unit;
• Noise during the operation of the column.

Scale on the tubular heat exchanger’s interior surfaces and soot deposits between the plates outside act as insulation and obstruct heat transfer from the flue gases to the heated medium, making them the most likely causes of these failures.

The heat exchanger needs to be taken out in order to be cleaned. To get rid of soot and dust, it is first thoroughly cleaned with a powerful water jet directed from the outside. To achieve a deeper clean, immerse the boiler in a dishwashing detergent solution for an hour. Afterwards, use a stiff brush and repeat the cleaning process under a cold water stream.

Strong water pressure is used to clean the interior surface in the opposite direction of the water flow. In the event that the scale cannot be entirely eliminated, the heater’s internal cavity will need to be filled with a unique solution that the manufacturer has recommended in the operating manual.

Many recommend washing with a 40–45 degree Celsius heated solution of citric acid, 100 g per liter of water. Feeding the solution into the inner area is required until foam begins to emerge from the other side. The inner surface should be completely rinsed with water pressure after the solution has been in the cavity for at least 15 to 20 minutes. Once the cleaning process is complete, put the thermal circuit back together before opening the gas valve and lighting the heater.

Dead batteries

When the batteries are just not usable, the most common failure is the absence of spark in the gas heater. However, users also have a great deal of trouble with this case. Battery-powered electric ignition columns generate spark. The flow sensor signals them to start when the hot water tap is opened. They generate current, which lights the igniter and ignites the gas entering the unit.

Weak batteries are unable to produce the required amperage, which prevents the gas from igniting and produces no spark. When the ignition system malfunctions in devices that use batteries for ignition, the charging elements are examined first and, if needed, replaced with new ones.

Flow mixing

In unadjusted heating modes, hot water must be cooled down if it emerges at a temperature higher than 55 degrees Celsius. The user simultaneously opens the faucet’s cold water tap, which causes the water supply system’s pressure to drop. In low-mode systems, this could result in the speaker cutting out entirely.

Because of the hardness salts Ca and Na in the water, which lower flow rates and overheat ribbed pipes, causing fistulas to form and water to leak into the interior of the column, this temperature of heated water also intensifies the processes of scale formation in the internal heating surfaces of the water heater.

More details! It is essential to use the regulator to set the heating limit temperature to no more than 50 C in order to avoid these kinds of temperature fluctuations.

Your Oasis gas heater can be annoying and worrisome if it won’t light or keeps going out. This problem could be caused by a number of variables, from straightforward problems to more complicated ones.

First, make sure there is an adequate supply of gas and that the gas valve is fully open. A partially closed valve may occasionally obstruct the gas flow, preventing the heater from lighting up correctly. Verify that the gas tank is not empty and look for any obstructions in the gas supply.

Check the pilot light after that. The pilot light may need to be adjusted or cleaned if it is flickering or not lighting at all. Over time, dirt, dust, or other debris can gather and impede the gas supply to the pilot light. Make sure the pilot light is properly positioned in relation to the burner and give it a thorough cleaning.

Check the thermocouple as well, which is a safety feature that detects whether the pilot light is on. As a safety measure, the thermocouple may cut off the gas supply to the heater if it is broken or positioned incorrectly. Make sure the thermocouple is properly positioned in relation to the pilot light and is clean.

If the problem still exists after you’ve tried these simple troubleshooting techniques, it can be a sign of a more complicated issue that needs to be looked at by a professional. Problems like a malfunctioning burner assembly, electronic ignition system, or gas valve may require the services of a trained technician.

In conclusion, diagnosing the cause of your Oasis gas heater’s failure to ignite or sporadic lighting entails checking a number of parts, including the pilot light, thermocouple, and gas supply. These steps will help you find and fix common problems so that your heater runs safely and effectively.
