Gas Patio Heater Regulator
It is important to know how to use propane patio heater if want to stay warm in the cold winter. Matthew Griffith, chief of the prevention department at the Montreal Fire Department, says that shoppers should look for products that have safety certifications.
The patio heater must be properly attached and there shouldn't be fire-prone material in the vicinity.
Pressure Regulator
Gas regulators are mechanical appliances that we use in our homes and cars every day without giving them a second thought. Their invention, created 135 years ago, changed the way natural gas heater for outdoor patio and propane are used for cooking, heating and welding with oxyfuel. The basic role of regulators is exactly similar, but there are many variations. The regulator is based on an element that senses pressure, often a fabric-reinforced diaphragm to regulate the position of the valve plug, and to limit the flow of gas.
The diaphragm connects to the stem of the valve by rods that go down through the set spring, over the diaphragm and into the valve. The mechanism is able to detect the gas pressure inside the house or pipeline and adjusts the valve plug's position to match the demand. As the consumption of gas in the house decreases the pressure between the regulator and the house also decreases as well. The diaphragm deflates downward and the valve plug is moved closer to the orifice to limit the flow. As the gas demand increases in the home the valve will open more, thereby increasing the flow.
The valve plug remains closed until the demand for the house decreases. This opens the valve to increase the flow. This process, referred to as"sizing," is the primary operation of the regulator.
As the valve opens it creates pressure in the main chamber, which is connected to the outlet port of the hose by a venturi tube. This pressure is controlled by changing the screw or handle on the outside of the regulator. When the screw is turned counterclockwise it expands and decreases the pressure; when it is turned clockwise, it lowers the pressure.
When selecting a pressure regulator make sure to keep in mind that the maximum and minimum nominal pressures are determined by commercial standards, and not the pressure at the supply line. The regulator must also be compatible with the hose you choose to use. Look for a hose that is marked as whistle-free which will feature alternating rings of different sizes to prevent resonant sounds from accumulating across the length of the hose.
Thermocouple
Thermocouples work on the principle that different metals in contact with each other at their ends can generate an electric current, even when they are at wildly different temperatures. They are used to detect the temperature difference between two points in a system, and transform this information into an electrical signal that can be read by thermocouple meters or any other instrument. Thermocouples are superior to other sensors, like thermistors. They can measure extremely high temperatures and work in harsh environments.
The measuring (or hot) junction is created by connecting two metals with different properties at one end, while at the other, the reference (or cold) junction, is kept at a constant temperature. Thermocouples are passive devices, meaning they don't require power in order to function. The voltage produced is proportional to the difference in temperatures between the reference and measuring junctions. Thermocouple manufacturers and metrology standards organizations such as NIST offer reference tables for the function E (T) displaystyle scriptstyle e(T) For each specific type of thermocouple.
There are three primary types of thermocouple junctions: an exposed, grounded, and welded wire. The exposed type of junction protrudes from the protective sheath, and has the fastest response. A thermocouple that is grounded is recommended for measurements in corrosive environments. A thermocouple that is welded is physically separated from the sheath by using mgO powder. This prevents moisture or gas from penetrating and causing errors.
The thermocouple that is welded also has the added benefit of being more vibration resistant. It is recommended to use in harsh environments and at pressures up to 3000 psi. A thermocouple that is damaged is usually caused by a lack in polarity. If the sheath is not properly polarized, the two ends of the thermocouple will have different voltages at the measurement junction, which can cause an inaccurate reading and possibly end up damaging the instrument. A malfunctioning thermocouple could be caused by an improperly installed or calibrated sensor.
Thermostat

Thermostats regulate the flow of energy into these cylinders to ensure that they do not overflow, yet still provide heat when needed. The thermostat is able to detect the temperature of the air that passes over it. The thermostat also senses when the room is cooling down to a comfortable temperature and turns off the heating.
Digital thermostats are the most popular. It makes use of a microcontroller to convert an electrical resistivity into an indication of temperature. It is able to perform this more accurately than the older mercury switch thermostats that used an mercury coil with three wires inside that would change according to temperature. This allowed it to tilt a mercury switch connected to the electrical circuit of the air conditioning or heater unit, turning it on or off.
A mechanical thermostat is a different type. It's a small cylinder filled with wax that begins to melt at a temperature of perhaps 180 degrees F (different thermostats open at different temperatures). A rod that is connected to the valve is then pressed into the wax and opens the valve when it's hot. As the room cools, the wax expands and the rod gets pulled back into the cylinder, thereby shutting the valve.
You can also program thermostats to alter the temperature at various times during the day. You can reduce energy usage by setting your heating to turn on and off while you're at work or sleeping, instead of being running all the time. You can also set your thermostat to come on sooner so that you can get home to a comfortable temperature. Thermostats often have a feature known as the heat anticipator, which stops the heater from switching off too early. This is because some parts of the house reach the desired temperature prior to the thermostat has even been set.
Pilot Light
Many modern heating systems, homes, and furnaces are no longer completely from pilot lights. However older homes still make use of them to ignite gas in the burner chamber. It is important to know how to safely relight the pilot light if it ever fails.
A pilot light generates tiny flames that heat a thermocouple, which generates electricity and holds the gas valve open. If the pilot flame goes out, the thermocouple cools and ceases to generate electricity, thereby closing the gas valve. Pilot lights are used on a majority of natural gas and propane patio gas appliances, including water heaters.
To light a pilot light, it is necessary first that you shut off the gas valve at the appliance. Then, you have to take out any doors or panels that might be in the way of accessing the pilot light. Locate the pilot light tube and follow the steps on the front of the appliance for opening 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 to keep the pilot light on. If it's accidentally shut off, the gas that is constantly venting out of the pilot light tube can accumulate in your home until sparks from a smoking cigarette or static electricity ignites it and triggers an explosion. To avoid this, the pilot tubes come with a built in cutoff valve.
In addition to the safety issues that a burning pilot light also consumes considerable energy. Numerous studies have revealed that a pilot light can burn between $7 and $18 worth of gas patio heater outdoor every month. This waste of fuel also puts a heavier load on the air conditioning system during summer use. Another concern with the pilot light is that it could attract spiders, which could spin webs that clog the pilot tubes. Finally, a constant flame could release trace amounts the mercaptan compound that produces the rotten egg smell that is found in natural gas. If you're concerned about these issues, you should consider buying a remote controlled gas fireplace or replacing your old fireplace with a new efficient model.
