If you're planning on cozying inside the cold winter air with a propane garden patio heater gas heater, it's crucial to know how to properly use the appliance. Matthew Griffith, prevention section chief of the Montreal fire department, said shoppers should choose items that have safety certifications.
It's also essential to ensure that there are no nearby combustible objects and that the patio heater is properly attached.
Pressure Regulator
gas patio heater regulators are a simple mechanical devices that we drive by daily in our cars and at home without giving them a second thought. Their invention, which took place 135 years ago, has changed the way propane and natural gas fire patio heater are utilized for cooking, heating and oxy-fuel welding. The basic purpose of regulators is the same, but there are numerous variations. The regulator uses a pressure sensing element typically a fabric-reinforced diaphragm, to control the position of the valve plug, and to limit the flow of gas.
The diaphragm is connected to the stem of the valve by rods that run through the diaphragm and set spring, then into the valve. The gas pressure coming from the pipeline or from the house is detected by this mechanism, and it adjusts the position of the valve plug to align it to the demand from the house. As the consumption of gas in the home decreases, so does the pressure between the regulator and the house. This causes the diaphragm of the regulator to deflate downward, and it moves the valve plug closer to the orifice, restricting the flow. As the demand for gas in the house grows, the valve opens further, increasing the flow of gas.
The valve plug is closed until the demand Gas Patio Heater Regulator for the house decreases. This opens the valve to increase the flow. This process, referred to as sizing, is the fundamental operation of the regulator.
When the valve is opened 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 the adjustment of a handle or screw located on the exterior of the regulator. When the screw is rotated counterclockwise it increases the pressure. If it is turned clockwise, it decreases the pressure.
When selecting a pressure regulator, remember that the minimum and maximum nominal pressures are determined by commercial standards, not the pressure at the supply line. The regulator must also be compatible with the hose you choose to use. Make sure you choose a hose that is whistle-free. It should have alternating rings of different sizes. This will prevent resonance noises from forming across the length.
Thermocouple
Thermocouples operate on the premise that different types of metals in contact with each other at their ends can produce an electric current, even when they are at very varying temperatures. They are used to identify temperature differences between points in the circuit and convert that information into an electronic signal that can be read by thermocouple gauges or any other instrument. Thermocouples offer a number of advantages over more common sensors, such as thermistors which include the ability to detect extremely high temperatures and operate in harsh environments.
The measuring (or hot) junction is created by connecting two dissimilar metals at one end, and the other end, known as the reference (or cold) junction, is maintained at an unchanging temperature. Thermocouples create small voltages but they are passive devices that don't need power to work. The voltage produced is proportional to the difference in temperature between the measuring and reference junctions. The thermocouple manufacturers and organizations that provide metrology standards, for example NIST offer reference tables for the function E (T). Displaystyle scriptstyle e(T) For each particular type of thermocouple.
There are three types of thermocouple connections: exposed grounded and welding. The exposed type of junction is a bit higher than the protective sheath and provides the fastest response time. A thermocouple grounded is recommended for measurements in corrosive environments. A thermocouple that is welded is physically isolated from the sheath by using mgO powder. This stops moisture or gas from penetrating and causing errors.
A thermocouple welded to a wire offers the added benefit of being more resistant to vibration. It is recommended for use in harsh environments, and with pressures up to 3000 psi. When a thermocouple is damaged, it is usually caused by a lack of polarity. If the sheath hasn't been polarized, Gas Patio Heater Regulator both ends of the thermocouple may have different voltages at their measurement junction. This could result in an inaccurate reading or even damage to the instrument. A sensor that is not properly calibrated or installed could cause a malfunctioning thermocouple.
Thermostat
Gas garden patio heater gas heaters in contrast to electric heaters that are hardwired to the wall they are portable and are powered by natural gas or propane. Thermostats regulate flow of energy into these cylinders in order to ensure that they don't overflow, yet still provide heat when needed. The thermostat achieves this by measuring the temperature of air that is passing through it. The thermostat also can tell whether the room is at a temperature that is comfortable and shuts off the heating.
Digital thermostats are the most popular. It uses a microcontroller to convert a fluctuating electrical resistance into an indication of temperature. It is able to perform this more accurately than previous mercury switch thermostats that employed an mercury coil with three wires in it that would change according to temperature. This allowed it to tilt a mercury switch that was connected to the electrical circuit of a heater or air conditioning unit, and turn it on or off.
Mechanical thermostats are another type. The thermostat is activated when the wax in a small cylinder starts to melt, which is around 180 degrees F. (Different thermostats have different opening temperatures). A rod that connects to the valve presses into the wax and opens the valve when it's hot. As the room cools the wax expands and the rod is pulled into the cylinder, closing the valve.
You can set thermostats to change the temperature at various times during the day. This lets you reduce energy consumption by setting your heating to go off and on during times of work or asleep, instead of being constantly on. You can also set your thermostat to come on earlier so that you will arrive home to an appropriate temperature. Thermostats are also usually equipped with an option called the heat anticipator that stops the heater from switching on too soon. This is due to the fact that different areas of the house typically reach the set temperature before the thermostat itself does.
Pilot Light
While many modern heating and home systems have eliminated pilot lights older furnaces and homes still rely on these devices to light gas in the chamber for burning. If the pilot light is ever extinguished, it's important to know how to re-light it safely.
A pilot light creates tiny flames that heat a thermocouple. The thermocouple generates electricity, and keeps the gas valve open. If the pilot flame goes out the thermocouple cools and ceases to produce electricity, thus closing the gas valve. Pilot lights are utilized on the majority of natural gas and propane appliances, such as water heaters.
Relighting a pilot light requires first that you shut off the gas valve in the appliance. Then you need to remove any doors or panels that may hinder getting to the pilot light. Follow the instructions on the front of the unit to open the tube for the pilot light. Once you've reopened the pilot switch, turn the knob on the gas valve to "on".
The main reason for leaving a pilot light on is to ensure safety. If you accidentally extinguish the pilot light, the gas constantly venting from the tube can build up in your home until a spark or static electricity ignites the gas and causes an explosive explosion. To avoid this, pilot tubes are equipped with a built in cutoff valve.
A constant burning pilot light is not only dangerous but also wastes energy. Different studies have proven that a pilot lamp can consume between $7 and $18 worth of gas per month. This wasted fuel is a bigger burden on the air conditioner during summer. Another concern with the pilot light is that it could attract spiders, which could spin webs that clog the pilot tubes. Additionally, a flame that is constant could release trace amounts the mercaptan compound that causes the rotten egg odor found in natural gas. If you're concerned about these problems, consider getting a remote control gas fire or replacing your old fireplace with a new, efficient model.
