Gas Patio Heater Regulator
It's crucial to know how to use propane patio heater gas regulator heater if you need to stay warm during the cold weather. Matthew Griffith, prevention section chief of Montreal's fire department, said that consumers should look for items that have safety certifications.
The patio heater should be properly connected and there shouldn't be any materials that could ignite nearby.
Pressure Regulator
Gas regulators are essentially mechanical devices that we use in our cars and homes every day without giving them a second thought. Their invention created 135 years ago, changed the way natural gas and propane gas patio heater are used for cooking, heating and oxyfuel welding. The basic role of regulators is exactly similar, but there are many variations. The regulator utilizes a pressure sensing element typically a fabric-reinforced diaphragm, which controls the position of a valve plug and limit the flow of gas patio fires.
The diaphragm is connected to the stem of the valve using rods that go down through the set spring, up through the diaphragm and into the valve. The gas pressure from the pipeline or from the house is sensed by this mechanism and it adjusts position of the valve plug to match it to the demand of the house. As the gas consumption in the home decreases as does the pressure between the regulator and the house. The diaphragm expands downwards and the valve plug moves closer to the orifice in order to limit flow. As the demand for gas increases in the home the valve will open more, thereby increasing the flow.
The valve plug is closed until the demand for the house decreases. The valve then opens to increase the flow. This process is referred to as size and is the primary function of the regulator.
When the valve is opened it creates pressure up in the main chamber of the regulator, which is attached to the port for hose outlet via the venturi tube (see picture). The pressure is controlled by changing the screw or handle located on the exterior of the regulator. When the screw is turned counterclockwise it increases and decreases the pressure. When it is turned clockwise it lowers the pressure.
When choosing a regulator for pressure be aware that the maximum and minimum nominal pressure is set by commercial standards, not the pressure of the gas in the supply line. The regulator should also be compatible with the hose you use. Find a hose that is labeled as whistle-free, with various sizes of rings to prevent resonant sounds from accumulating throughout the hose.
Thermocouple
Thermocouples are based upon the idea that two different metals that are in contact at one end generate a voltage potential, even when they are at different temperatures. They are used to determine the temperature differences between different points in the circuit and convert that data into an electronic signal that can be read by thermocouple gauges or another instrument. Thermocouples have several advantages over conventional sensors like thermistors, including the ability to measure extremely high temperatures and to function in harsh environments.
A pair of metals that are dissimilar are connected at one end of the sensor to create the measuring (aka hot) junction, and the other is kept at a fixed temperature, also known as the reference (aka cold) junction. Thermocouples are passive devices which means that they don't require power to operate. The voltage generated is proportional to the difference in temperature between the reference and measuring junctions. The thermocouple manufacturers and organizations that provide metrology standards, such as NIST, provide reference tables for the function E (T). Displaystyle scriptstyle e(T) for each type of thermocouple.
There are three kinds of thermocouple connections: exposed grounded and welding. The type of junction that is exposed protrudes from the protective sheath and has the fastest response. For measurements in corrosive environments, a grounded thermocouple should be used. A thermocouple that is welded is physically isolated from its sheath with mgO powder. This prevents gas or moisture from leaking into the sheath and causing error.
A welded wire thermocouple also comes with the added benefit of being more resistant to vibration. It is recommended for use in harsh environments and at pressures as high as 3000 psi. A thermocouple that is damaged is usually due to an insufficient polarity. If the sheath hasn't been polarized, both ends of the thermocouple may have different voltages at their measurement junction. This could result in an incorrect reading or damage the instrument. A sensor that isn't properly calibrated or placed in the right place can also cause a faulty thermocouple.
Thermostat
Unlike electric heaters which have to be wired directly into the wall gas patio heater gas heaters are portable and utilize propane or natural gas cylinders as fuel. Thermostats regulate the flow of energy into these cylinders to ensure that they don't overflow, yet still provide warmth when required. The thermostat accomplishes this by sensing the temperature of the air that flows over it. The thermostat also determines if the room has cooled down to a comfortable temperature and switches the heating off.
Digital thermostats are the most popular. It utilizes a microcontroller in order to convert a fluctuating electrical resistance into the temperature measurement. It is able to do this more accurately than the older mercury switch thermostats that used a mercury coil with three wires that would move based on temperature. This allowed the thermostat to tilt a mercury switch that was connected to an electrical circuit for a heater or air conditioner by turning it off and on.
A mechanical thermostat is a different type. The thermostat is activated when the wax inside a small cylinder starts to melt, which is approximately 180 degrees F. (Different thermostats have different opening temperatures). A rod connected to the valve is then pressed into this wax and opens the valve when it's hot. As the room cools down the wax expands and the rod is pushed into the cylinder, closing the valve.
There are also thermostats that can be programmed to change at different times of the day. You can save energy by programming your heating to switch off and on when you are working, or asleep, instead of being always on. You can also set the thermostat to turn on earlier, so that your home will be a comfortable temperature when you arrive back from work or school. Thermostats are also usually equipped with an element called the heat anticipator that prevents the heater from turning off too early. This is because different parts of the house often reach the set temperature before the thermostat does.
Pilot Light
Although many modern heating and home systems have eliminated pilot lights older furnaces and homes still use these devices to light gas in the chamber for burning. If the pilot light ever extinguished, it's important to know how to light it safely.
A pilot light generates a small flame which heats the thermocouple. The thermocouple generates electricity, and keeps the gas valve open. If the pilot flame dies the thermocouple cools and ceases to produce electricity, thus closing the gas valve. Pilot lights are found in the majority of propane and natural appliances, including fireplaces, water heaters barbecues, grills, furnaces and hot tubs.
To relight the pilot, you first need to shut off the garden gas patio heater at the appliance. The next step is to remove any panels or doors that may be blocking the access to the pilot light. Find the pilot light tube and follow the procedure printed on the front of the appliance to open it. After you've re-lit your pilot light, return the knob on the gas valve to the "on" position.
The main reason for leaving a pilot light on is to ensure safety. If you accidentally extinguish the pilot light, gas that is constantly venting out of the tube could accumulate in your home until an electric spark or static charge ignites the gas and causes an explosive explosion. The tubes designed for pilots include an inbuilt cutoff valve to stop this from happening.
A constant burning pilot light is not only dangerous, but it also wastes energy. The pilot light consumes between $7 and $18 worth of gas every month, based on numerous studies. The wasted fuel also puts an additional burden on the air conditioning system during summer use. Another issue with a pilot light is that it could attract spiders, which could create webs that block the pilot tubes. Also, a constant flame can release trace amounts of the compound mercaptan, which causes the rotten egg odor found in natural gas. If you're ever concerned about these issues, think about purchasing a gas fireplace with a remote control or replacing an old fireplace with a more effective, modern design.
