If you're planning on cozying with the cold outside with a propane patio 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 look for products that are safe to use.
The garden patio heater gas heater must be securely attached and there should be no fire-prone material in the vicinity.
Pressure Regulator
Gas regulators are essentially mechanical appliances that we use in our cars and homes every day without giving them a second glance. Their invention, 135 years ago, has changed the way propane and natural gas are used for heating, cooking, and welding with oxy-fuel. There are a variety of variations in regulator design, however their fundamental purpose is the same. The regulator uses an element that senses pressure, typically a fabric-reinforced dialythm, to regulate a valve plug's location and limit the flow of gas.
The diaphragm is connected to the valve stem with rods that run down through the set spring, over the diaphragm and into the valve. The pressure of black gas patio heater coming from the house or the pipeline is detected by this mechanism, and it adjusts the position of the valve plug to align it with 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. This causes the diaphragm to decrease in size, and then it moves the valve plug closer to the orifice, limiting the flow. As the gas demand increases in the home, the valve opens more, increasing the flow.
When the valve plug is shut, it is held in place by the set spring force until the demand of the house decreases, which opens the valve further to increase flow. This process is referred to as sizing and it is the primary function of the regulator.
As the valve opens, a pressure is built up in the main chamber of the regulator, which is connected to the port for hose outlet with the venturi tube (see image). This pressure is controlled by adjusting a screw or handle located 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 selecting a pressure regulator make sure to keep in mind that the minimum and maximum nominal pressures are established by commercial standards, and not the pressure at the supply line. The regulator should be compatible with the hose you are using. Choose a hose which is labeled as whistle-free, with various sizes of rings to prevent resonant sounds from building up throughout the hose.
Thermocouple
Thermocouples are based on the idea that metals of different composition when in contact at their ends can produce an electric current, even when they are at wildly different temperatures. They are used to detect temperatures that differ between points of a circuit and convert that data into an electronic signal that can be read by thermocouple gauges or any other instrument. Thermocouples are superior to other sensors, like thermostors. They are able to measure extremely high temperatures and operate in corrosive environments.
A pair of different metals is connected to one end of the sensor to form the measuring (aka hot) junction, and the other end is kept at a fixed temperature, known as the reference (aka cold) junction. Thermocouples are passive devices, meaning they do not require power to operate. The voltage produced is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers and metrology standards organizations such as NIST provide reference tables of the function E (T) displaystyle scriptstyle e(T) for each specific thermocouple type.
There are three main types of thermocouple junctions: an exposed, grounded and wire that is welded. The exposed style of junction protrudes from the protective sheath and provides the fastest response. For measurements in corrosive conditions, a grounded thermocouple should be utilized. A welded wire thermocouple is physically isolated from the sheath with mgO powder to stop the penetration of moisture or gas heater for outdoor patio that could cause errors.
The welded wire thermocouple has the additional benefit of being more vibration resistant. It is recommended to use in harsh environments and at pressures of up to 3000 psi. If a thermocouple becomes damaged, it's usually caused by a lack in the polarity. If the sheath isn't polarized, the two ends of the thermocouple will have unequal voltages at the measurement junction that could lead to an incorrect reading and cause damage to the instrument. A sensor that isn't properly calibrated or installed can also result in a malfunctioning thermocouple.
Thermostat
Gas patio heaters unlike electric heaters which are wired to the wall, are portable and run on natural gas or propane. The thermostats regulate the flow energy to these cylinders, so that they don't overflow, but they still provide heat when required. The thermostat detects the temperature of the air that passes over it. The thermostat also determines if the room has cooled down to a comfortable temperature and shuts off the heating.
The most popular type of thermostat is one that is digital. It utilizes a microcontroller that converts a changing electrical resistance into a reading of temperature. It can do this more accurately than the older mercury switch thermostats which used a coil of mercury with three wires in it that would move depending on the temperature. This allowed the thermostat to tilt a switch made of mercury that was connected to an electrical circuit that was used to power the air conditioner or heater by turning it off and on.
Another type of thermostat is one that is mechanical. The thermostat is opened when the wax contained in a small cylinder starts to melt, which is around 180 degrees F. (Different thermostats have different opening temperatures). When the wax is hot, a rod connected to the thermostat opens the valve. As the room cools, the wax contracts and the rod gets pulled back into the cylinder, shutting the valve.
You can also program thermostats to alter the temperature at different times during the daytime. You can save energy by setting your heating to switch off and on when you are working, or sleeping, instead of having it on all the time. You can also set your thermostat to come on sooner to ensure that you arrive home to an appropriate temperature. Thermostats often include a feature called a heat anticipator that prevents the heating system from turning on too early. This is because some parts of the home are at the desired temperature prior to the thermostat has even been set.
Pilot Light
Many newer heating systems, Gas Patio Heater Regulator homes and furnaces have eliminated entirely with pilot lights. However older homes still rely on them to ignite gas in the burner chamber. If the pilot light ever shut off, it's crucial to know how to light it in a safe manner.
A pilot light creates a small flame which heats the thermocouple. This thermocouple generates electricity and keeps the gas valve open. When the pilot flame goes off, the thermocouple cools down and ceases to produce electricity, thereby closing the valve. Pilot lights are utilized on a majority of natural gas and propane appliances, including water heaters.
To relight a pilot light, you must first shut off the gas on the appliance. You must then remove any panels or doors that might be blocking access to the pilot light. Locate the pilot light tube and follow the steps on the back of the appliance for opening it. Once you've switched off the pilot then turn the knob of the gas valve back to "on".
The primary reason to keep the pilot light on is for safety reasons. If you accidentally shut off the pilot light, the gas that is constantly escaping from the tube could accumulate in your house until the spark or static electricity sparks the gas, causing an explosive explosion. To avoid this, pilot tubes are equipped with an integrated cutoff valve.
A pilot light that is constantly burning is not just hazardous however, it also consumes energy. The pilot light consumes between $7 and $18 worth of gas every month, based on various studies. This wasted fuel also places a heavier load on the air cooling system in summer. A pilot light can also attract spiders which can spin webs and block the pilot tubes. A constant flame could release tiny amounts of the chemical Mercaptan that is responsible for the smell of rotten eggs that is common in natural gas. If you're ever concerned about these issues, think about purchasing a gas fire with a remote control or replacing your fireplace with a more efficient and modern-day model.
