If you're planning on cozying up in the cold outdoors with a propane patio heater, it's important to know how to properly make use of this device. Matthew Griffith, prevention section chief of Montreal's fire department, advised that customers should be looking for items that have safety certifications.
The patio heater must be properly connected and there shouldn't be any materials that could ignite nearby.
Pressure Regulator
Gas regulators are simple mechanical appliances we use in our homes and cars every day without even giving them a second thought. Their invention, first introduced 135 years ago, changed the way propane and natural gas are used for cooking, heating and welding using oxyfuel. The fundamental role of regulators is exactly the same, however there are numerous variations. The regulator is based on a pressure sensing element typically a fabric-reinforced diaphragm, to control the position of a valve plug and limit the flow of gas.
The diaphragm is connected to the stem of the valve using rods that go down through the set spring, over the diaphragm, and finally into the valve. The mechanism is able to detect the gas pressure in the home or pipeline and adjusts the position of the valve plug to match the demand. As the gas consumption in the home decreases and the pressure decreases between regulator and house. The diaphragm deflates downward and the valve plug moves closer to the orifice to limit flow. As the demand for gas grows in the home the valve will open more, thereby increasing the flow.
The valve plug remains shut until the demand of the house decreases. This opens the valve to increase the flow. This process, called 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 hose's outlet port via venturi tubes. This pressure is controlled by changing the screw or handle on the outside of the regulator. When the screw is turned counterclockwise it moves up and reduces the pressure. However, when it is turned clockwise it reduces the pressure.
When you are choosing a regulator for your pressure be aware that the maximum and minimum nominal pressures are set by commercial standards, and not the pressure at the supply line. The regulator must be compatible with the hose you are using. Find a hose marked whistle-free. It will have alternating rings of different sizes. This will prevent resonance noises from forming throughout the length.
Thermocouple
Thermocouples work on the principle that different metals in contact with each other at their ends can generate the voltage even if they are at very varying temperatures. They are used to detect the temperature differences between two points in a system and convert this data into an electrical signal that can then be read by a thermocouple meter or other instrument. Thermocouples possess several advantages over more common sensors such as thermistors, which include the ability to detect very high-temperatures and to operate in environments that are corrosive.
The measuring (or hot) junction is formed by joining two metals that are not compatible at one end, and the other end, known as the reference (or cold) junction, is kept at a constant temperature. Thermocouples produce small gas patio heater voltages, however, they are passive devices that do not require power to perform their functions. The voltage produced is proportional to the temperature difference between the measuring junction and the reference junction. Manufacturers of thermocouples as well as organizations that offer metrology standards, like NIST, provide reference tables for the function E (T). displaystyle scriptstyle e(T) For each specific type of thermocouple.
There are three types of thermocouple connections: exposed, grounded and welded. The exposed junction style extends out of the protective sheath and offers the fastest response time. A grounded thermocouple is recommended for testing in corrosive environments. A thermocouple welded to a wire is physically separated from the sheath by mgO powder to prevent penetration of gas or moisture which could cause mistakes.
A thermocouple welded to a wire has the added benefit of being more resistant to vibration. It is recommended to use it in extreme environments with pressures of up to 3000 psi. When a thermocouple is damaged, it's usually caused due to a lack of the polarity. If the sheath does not appear to be polarized, the two ends of the thermocouple will have different voltages at the junction of measurement, which can cause an incorrect reading and Gas Patio Heater Regulator end up damaging the instrument. A malfunctioning thermocouple could be caused by an improperly installed or calibrated sensor.
Thermostat
Contrary to electric heaters, which need to be hardwired into the wall, gas patio heaters are portable and use propane or natural gas cylinders to fuel. The thermostats regulate the flow energy to these cylinders in order they don't spill over, however they can still provide heat when needed. The thermostat accomplishes this by detecting the temperature of the air that flows over it. The thermostat also determines if the room has been cooled to a comfortable temperature and shuts off the heating.
Digital thermostats are among the most commonly used. It uses a microcontroller to convert a fluctuating electrical resistivity into a temperature reading. It is able to perform this task more accurately than the older mercury switch thermostats, which utilized mercury coils with three wires inside that would change according to temperature. This enabled it to tilt the mercury switch connected to the electrical circuit of the air conditioning or heater unit, and turn it off or on.
A mechanical thermostat is a different type. It is a small cylinder filled with wax that starts to melt when it reaches a temperature of perhaps 180 degrees F (different thermostats open at different temperatures). When the wax is hot, a rod connected to the thermostat opens the valve. As the room cools the wax shrinks and the rod is pulled into the cylinder to close the valve.
There are thermostats that can be programmed to change at different times during the day. You can reduce energy usage by programming your heating system to be turned off and on while you're at work or sleeping, instead of having it running all the time. You can also set your thermostat to turn on sooner so that you will arrive home to a comfortable temperature. Thermostats often have an option called the heat anticipateor which prevents the heater from turning off too early. This is because parts of the house often reach the set temperature before the thermostat itself.
Pilot Light
Although many modern heating and home systems have done away with pilot lights older furnaces and homes still use these devices to light the gas in the burner chamber. If the pilot light ever snuffed out, it's vital to know how to light it safely.
A pilot light produces tiny flames that heat a thermocouple. The thermocouple generates 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 utilized on a majority of natural gas patio heater amazon and propane appliances, like water heaters.
Relighting a pilot light requires first that you shut off the gas valve in the appliance. Then, you must remove any doors or panels that could be blocking getting to the pilot light. Find the pilot light tube and Gas Patio Heater Regulator carefully follow the procedure printed on the front of the appliance to open it. After you've lit the pilot light, turn the knob on the gas for patio heater 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 may accumulate in your home until sparks from a cigarette lighter or static electricity ignites it and causes an explosion. Pilot tubes are designed to include a built-in cutoff valve that can keep this from happening.
In addition to the safety issues the burning of a pilot light also consumes a significant amount of energy. The pilot light consumes between $7 to $18 worth of gas every month, based on numerous studies. This wasted fuel also places a heavier load on the air cooling system during summer time. Another concern with pilot lights is that it can attract spiders, who can spin webs that can clog pilot tubes. Also, a constant flame could release trace amounts the mercaptan compound, which produces the rotten egg smell that is present in natural gas. If you are ever concerned about these issues, you should consider purchasing a gas fireplace with a remote control or replacing your fireplace with a more effective, modern design.
