If you're looking to cozy up in the cold outdoors with a propane patio heater, it's crucial to understand how to use this appliance. Matthew Griffith, prevention section chief of Montreal's fire department, advised that customers should choose items that have safety certifications.
It's also crucial to ensure that there aren't any combustible materials in the vicinity and that the patio heater natural gas heater is properly attached.
Pressure Regulator
Gas regulators are simple mechanical appliances we use in our homes and cars every day without even giving them a second glance. Their invention, created 135 years ago, has revolutionized how propane and natural gas patio heater outdoor are used for heating, cooking and welding with oxyfuel. The basic function of regulators is the same, however there are numerous variations. The regulator is based on an element that senses pressure, typically a fabric-reinforced dialythm, to control a valve's position and restrict the flow of gas.
The diaphragm is linked to the stem of the valve by a rod that runs through the set spring, through the diaphragm and into the valve. The gas pressure coming from the pipeline or from the house is sensed by this mechanism and it adjusts the position of the valve plug to match it with the demand from the house. As the gas consumption in the home decreases, so does the pressure between regulator and house. This causes the diaphragm of the regulator to decrease in size, and then it moves the valve plug closer to the orifice, which limits flow. As the demand for gas grows in the home the valve opens up more, thereby 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 to increase the flow. This process, called sizing, is the fundamental operation of the regulator.
As the valve opens it creates pressure up in the main chamber of the regulator, which is attached to the outlet port of the hose by venturi tubes (see image). The pressure can be adjusted by turning the handle or screw located on the outside of the regulator. When the screw is turned counterclockwise, it moves up and reduces the pressure; when it is turned clockwise it decreases the pressure.
When choosing a pressure regulator, remember that the minimum and maximum nominal pressures are established by commercial standards, and not the pressure at the supply line. The regulator must be compatible with your hose. Find a hose marked whistle-free. It should feature alternating rings that are different sizes. This will stop the resonant sounds from building up along the length.
Thermocouple
Thermocouples work on the principle that different metals when in contact at their ends can generate the voltage even if they are at very varying temperatures. They are used to determine temperatures that differ between points of the circuit and convert that information into an electronic signal that can be read by a thermocouple gauge or other instrument. Thermocouples have several advantages over conventional sensors such as thermistors, including the ability to measure extremely high temperatures and to function in corrosive environments.
A pair of dissimilar metals is joined at one end of the sensor, forming the measuring (aka hot) junction, while the other end is kept at a fixed temperature, known as the reference (aka cold) junction. Thermocouples are passive devices, meaning they don't require power in order to function. The voltage produced is proportional to the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers as well as 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 types of thermocouple connections: exposed, grounded and welding. The exposed style of junction protrudes out of the protective sheath, and provides the fastest response time. For measurements in corrosive conditions, a grounded thermocouple should be utilized. A thermocouple welded to a wire is physically insulated from the sheath with mgO powder to stop the penetration of moisture or gas that could lead to errors.
A welded wire thermocouple also comes with the added benefit of being more resistant to vibration. It is recommended for use in harsh environments, and with pressures of up to 3000 psi. A thermocouple that has been damaged is usually caused by the lack of polarity. If the sheath hasn't been correctly polarized, the two ends of the thermocouple could have different voltages at their junction for measurement. This can lead to an inaccurate reading, or even damage the instrument. A defective thermocouple may result from an incorrectly calibrated or installed sensor.
Thermostat
Gas patio heaters in contrast to electric heaters that are wired to the wall are portable and operate on propane or natural gas. Thermostats regulate the flow of energy into these cylinders to ensure that they don't overflow, yet still provide heat as needed. 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 level and turns off the heating.
The most popular type of thermostat is a digital one. It is controlled by a microcontroller which converts a fluctuating electrical resistance into a reading of temperature. It can do this much more accurately than earlier mercury switch thermostats that used a coil of mercury that had three wires that would move depending on the temperature. This enabled the thermostat to tilt a switch made of mercury that was connected to an electrical circuit to an air conditioner or heater switching it on and off.
A mechanical thermostat is a different type. The thermostat is activated when the wax inside a small cylinder starts to melt, which is around 180 degrees F. (Different thermostats have different opening temperatures). A rod that is connected to the valve presses into this wax and opens the valve when it's hot. As the room cools, the wax contracts and the rod is pushed into the cylinder, closing the valve.
You can also program thermostats to change the temperature at different time of the daytime. This can help you conserve energy by setting your heating to turn off and on when you are working or sleeping, rather than having it on constantly. You can also set your thermostat to come on earlier to ensure that you arrive home to an appropriate temperature. Thermostats are also usually equipped with an element called the heat anticipator that stops the heater from switching on too quickly. This is because different parts of the home often reach the set temperature before the thermostat does.
Pilot Light
Many modern homes, heating systems and furnaces have done away completely from pilot lights. However, older homes still use them to ignite gas in the burner chamber. If the pilot light ever extinguished, it's important to know how to re-light it in a safe manner.
A pilot light creates small flames that warm the thermocouple. This produces electricity and keeps the gas valve open. If the pilot flame dies the thermocouple cools and stops generating electricity, thereby closing the gas valve. Pilot lights are used in the majority of propane and natural appliances, including fireplaces, water heaters barbecues, grills, furnaces and hot tubs.
The process of lighting a pilot light requires that you first turn off the gas valve in the appliance. Then you need to remove any doors or panels that might hinder getting to the pilot light. Follow the directions on the front of the unit to open the pilot light tube. After you've re-lit your pilot light, return the knob on the pyramid gas patio heater valve to the "on" position.
The primary reason to keep a pilot light on is to ensure safety. If it's accidentally turned off the gas constantly venting out of the pilot light tube can build up in your home until a spark from the cigarette lighter or static electricity ignites it and causes an explosion. To prevent this from happening, pilot tubes have a built in cutoff valve.
A pilot light that is constantly burning is not just dangerous, but it also wastes energy. Numerous studies have revealed that a pilot light can consume between $7 and $18 of gas each month. The wasted fuel also puts an additional burden on the air conditioning system during summer use. A pilot light may attract spiders which can spin webs and block the pilot tubes. A constant flame could release tiny amounts of the chemical Mercaptan, which is the cause of the rotten-egg smell in natural gas patio fires. If you're ever worried about these issues, think about purchasing a remote-controlled gas fireplace or replacing your old fireplace with a new, efficient model.
