Gas Patio Heater Regulator
It's crucial to know how to use propane patio outdoor gas heater heater if need to stay warm during the cold winter. Matthew Griffith, chief of the prevention department of Montreal's Fire Department says that shoppers should be looking for products that have safety certifications.
It's also important to ensure that there are no nearby combustible objects and that the patio heater is properly connected.
Pressure Regulator
Gas regulators are simple mechanical appliances that we use in our cars and homes every day without giving them a second glance. Their invention, first introduced 135 years ago, has revolutionized how natural gas and propane are used for heating, cooking and oxyfuel welding. There are a variety of variations in the design of regulators, however their primary purpose is the same. The regulator utilizes a pressure sensing element which is usually a fabric reinforced diaphragm, which controls the position of a valve plug and limit the flow of gas.
The diaphragm connects to the stem of the valve using rods that go through the set spring, through the diaphragm and into the valve. The pressure of gas coming from the pipeline or the house is detected by this mechanism and it adjusts position of the valve plug to align it to the demand from the house. As the use of gas in the house decreases the pressure between the regulator and the house reduces as well. The diaphragm is deflated downward and the valve plug moves closer to the orifice to restrict flow. As the demand for gas in the house increases the valve expands and increases the flow of gas.
When the valve plug is shut, it is held in position by the spring force until the house's demand decreases, which opens the valve further to increase the flow. This process, referred to as sizing, is the fundamental operation of the regulator.
When the valve is opened the pressure builds up in the main chamber, which is connected to the outlet port of the hose via venturi tubes. The pressure can be regulated by turning the screw or handle on the outside of the regulator. When the screw is rotated counterclockwise it increases the pressure. When it is rotated clockwise it decreases the pressure.
When you are choosing a regulator for your pressure, remember that the maximum and minimal nominal pressures are established by commercial gas patio heaters standards and NOT the pressure at the supply line. The regulator must be compatible with the hose you are using. Look for a hose labeled whistle-free. It should have alternating rings of different sizes. This will stop resonance noises from forming throughout the length.
Thermocouple
Thermocouples operate on the premise that different types of metals in contact at their ends can generate the voltage even if they are at wildly different temperatures. They are used to determine temperatures that differ between points of the circuit and transform that data into an electronic signal that can be read by thermocouple gauges or any other instrument. Thermocouples possess several advantages over more common sensors such as thermistors, for instance, the ability to measure very high-temperatures and to operate in corrosive environments.
The measuring (or hot) junction is formed by connecting two metals with different properties at one end, while at the other, the reference (or cold) junction, is maintained at an unchanging temperature. Thermocouples create small voltages however, they're passive devices that don't need power to perform their functions. The voltage generated is proportional to the temperature difference between the reference and measuring junctions. Manufacturers of thermocouples and organizations that provide metrology standards, like NIST offer reference tables for the function E (T). displaystyle scriptstyle e(T) for each specific thermocouple type.
There are three kinds of thermocouple junctions: an exposed, grounded and weld wire. The exposed style of junction is a bit higher than the protective sheath and provides the fastest response time. A thermocouple that is grounded is recommended for testing in corrosive environments. A thermocouple welded-wire is physically isolated from its sheath using mgO powder. This stops moisture or gas from penetrating and causing problems.
A welded wire thermocouple also comes with the added benefit of being more resistant to vibration. It is recommended to use in harsh environments and at pressures up to 3000 psi. A thermocouple that is damaged is usually the result of the lack of polarity. If the sheath does not appear to be polarized, the two ends of the thermocouple be in a state of discordant voltages at the measurement junction that could lead to an incorrect reading and cause damage to the instrument. A faulty thermocouple can also be caused by a poorly calibrated or installed sensor.
Thermostat
Gas patio heaters in contrast to electric heaters that are hardwired to the wall, are portable and operate on propane or natural gas. Thermostats regulate the flow of energy into these cylinders in order to ensure that they do not overflow but still provide heat when needed. The thermostat senses the temperature of the air passing over it. The thermostat also detects when the room is cooling down to a comfortable level and shuts off the heating.
Digital thermostats are the most popular. It utilizes a microcontroller in order to convert an electrical resistance into a temperature reading. It is able to accomplish this much more accurately than earlier mercury switch thermostats which used a mercury coil with three wires that moved according to the temperature. This allowed it to tilt the mercury switch connected to the electrical circuit of a heater or air conditioning unit, and turn it on or off.
A mechanical thermostat is a different kind. The thermostat is opened when the wax in the small cylinder begins to melt, which is about 180 degrees F. (Different thermostats have different opening temperatures). A rod connected to the valve then presses into this wax and opens the valve when it's hot. As the room cools down, the wax contracts and the rod is pulled into the cylinder to close the valve.
You can also program thermostats to alter the temperature at various times during the daytime. You can reduce energy usage by programming your heating system to switch off and on when you are at work, or sleeping, instead of having it running all the time. You can also set your thermostat to come on sooner to ensure that you arrive home to a comfortable temperature. Thermostats often include a feature called a heat anticipator that prevents the heater from coming on too early. This is because parts of the home often attain the temperature set before the thermostat itself.
Pilot Light
Many newer heating systems, homes, and furnaces have done away completely of pilot lights. However, older homes still use them to ignite gas in the burner chamber. If the pilot light is ever shut off, it's crucial to know how to light it safely.
A pilot light creates tiny flames that heat the thermocouple. The thermocouple produces electricity and keeps the gas valve open. When the pilot flame stops the thermocouple cools and stops producing electricity, thereby closing the valve. Pilot lights are found in a wide range of propane patio gas- and natural gas-powered appliances, including fireplaces, water heaters furnaces, ranges, barbecues and hot tubs.
To relight a pilot, you first need to shut off the gas at the appliance. You must then remove any panels or doors that might be blocking access to the pilot light. Find the pilot light tube and carefully follow the procedure printed on the back of the appliance to open it. After you've re-lit your pilot light, turn the knob on the gas valve to the "on" position.
Safety is the main reason for leaving the pilot light on. If you accidentally extinguish the pilot light, the gas constantly venting from the tube could build up in your home until a spark or static electricity ignites the gas and causes an explosive explosion. To avoid this, pilot tubes have an integrated cutoff valve.
A constant burning pilot light is not just dangerous however, it also consumes energy. Various studies have shown that a pilot light can burn between $7 and $18 worth of gas per month. This fuel is wasted and creates a greater burden on the air conditioner during the summer. Pilot lights can attract spiders which can spin webs and clog up the pilot tubes. Additionally, a flame that is constant can release trace amounts of the mercaptan compound, which creates the rotten egg smell that is present in natural gas. If you're ever worried about these issues, you should consider purchasing a remote-controlled gas fireplace or replacing your old fireplace with a more modern, efficient model.
