It is important to know how to use a propane patio heater gas regulator heater if are looking to keep warm in the cold winter. Matthew Griffith, prevention section chief of the Montreal fire department, said that consumers should choose products that have safety certifications.
The patio heater should be properly connected and there should be no combustible material nearby.
Pressure Regulator
Gas regulators are mechanical appliances we use in our vehicles and homes every day without giving them a second thought. Their invention made 135 years ago changed the way propane and natural gas are used for heating, cooking and welding with oxyfuel. There are a number of variations in regulator design, however their primary function is the identical. The regulator is based on an element that senses pressure, usually a fabric-reinforced dialythm, to regulate a valve plug's location and limit the flow of gas powered patio heater.
The diaphragm is linked to the valve stem with a rod that runs down through the set spring, through the diaphragm and into the valve. This mechanism senses the gas pressure in the house or pipeline and adjusts the valve plug's position to match the demand. As the gas consumption in the home decreases as does the pressure between regulator and house. This causes the diaphragm to decrease in size, and then it pushes the valve plug closer to the orifice, limiting the flow. As the gas demand increases in the home, the valve opens more, thereby increasing the flow.
The valve plug stays closed until the demand for the house decreases. The valve then opens to increase the flow. This process, also known as"sizing," is the primary operation of the regulator.
As the valve opens, a pressure is built up in the main chamber of the regulator, which is attached to the outlet port of the hose via venturi tubes (see picture). This pressure can be adjusted by turning the handle or screw located on the outside regulator. When the screw is rotated counterclockwise it increases the pressure. If it is turned clockwise, it decreases the pressure.
When choosing a regulator for pressure be aware that the maximum and minimum nominal pressure is set by commercial standards, not the pressure of the gas in the supply line. The regulator must be compatible with the hose you use. Find a hose that is labeled as whistle-free, with various sizes of rings to prevent resonant sound from accumulating along the length of the hose.
Thermocouple
Thermocouples operate on the idea that two different metals in contact at each end produce a voltage even if they are at different temperatures. They are used to measure the temperature difference between two points in a system and convert this information into an electrical signal that can be read by a thermocouple meter or other instrument. Thermocouples have several advantages over more common sensors, such as thermistors for instance, the ability to measure extremely high temperatures and operate in harsh environments.
A pair of dissimilar metals are connected to one end of the sensor, forming the measuring (aka hot) junction, while the other end is maintained at a set temperature, known as the reference (aka cold) junction. Thermocouples produce small voltages, however, they're passive devices that don't require power to function. The voltage generated is proportional the temperature difference between the measuring junction and the reference junction. Thermocouple manufacturers as well as metrology standards organizations such as NIST provide tables of reference for the function E (T) displaystyle scriptstyle e(T) For each type of thermocouple.
There are three primary types of thermocouple junctions: an exposed, grounded and welded wire. The exposed style of junction extends out of the protective sheath, and has the fastest response. A grounded thermocouple is recommended for measurements in corrosive environments. A welded-wire thermocouple is physically separated from the sheath with mgO powder. This prevents gas or moisture from leaking into the sheath and causing errors.
A thermocouple that is welded has the added benefit of being more resistant to vibration. It is recommended to use in harsh environments and at pressures of up to 3000 psi. A thermocouple that is damaged is usually caused by a lack in polarity. If the sheath does not appear to be properly polarized, the two ends of the thermocouple have different voltages at the measurement junction that could lead to an incorrect reading and Gas Patio Heater Regulator end up damaging the instrument. A sensor that isn't properly calibrated or placed in the right place can cause a malfunctioning thermocouple.
Thermostat
Gas patio heaters unlike electric heaters which are wired to the wall are portable and are powered by natural gas or propane. Thermostats regulate the flow energy into these cylinders to ensure that they do not overflow, yet still provide heat when needed. The thermostat senses the temperature of air passing over it. The thermostat also determines if the room is cooling down to a comfortable level and shuts off the heating.
The most popular type of thermostat is one that is digital. It utilizes a microcontroller in order to convert a changing electrical resistivity into the temperature measurement. It is able to perform this more accurately than the older mercury switch thermostats, which used a mercury coil with three wires inside that moved based on temperature. This allowed the thermostat to tilt a switch made of mercury that was connected to an electrical circuit to the air conditioner or heater by turning it off and on.
Mechanical thermostats are another kind. The thermostat is opened when the wax inside the small cylinder begins to melt, which is approximately 180 degrees F. (Different thermostats have different opening temperatures). When the wax is hot, a rod attached to the thermostat opens the valve. As the room cools down, the wax contracts and the rod is pushed into the cylinder to close the valve.
You can set thermostats to change the temperature at various times during the daytime. This allows you to save energy by setting your heating to come on and off during times of work or sleeping, instead of being constantly on. You can also set the thermostat to turn on earlier so that your home will be at a comfortable temperature when you arrive back from school or work. Thermostats usually come with a feature known as the heat anticipator, which prevents the heating system from turning on too early. This is because different parts of the home often attain the temperature set 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 gas in the burner chamber. It's essential to know how to safely to relight the pilot light in case it ever fails.
A pilot light produces small flames that are heated by the thermocouple. This thermocouple generates electricity, and keeps the gas flame patio heater valve open. If the pilot flame goes out, the thermocouple cools and ceases to produce electricity, closing the gas valve. Pilot lights are used in the majority of propane and natural appliances, such as water heaters, fireplaces, barbecues, grills, furnaces and hot tubs.
To relight a pilot, you must first turn off the gas at the appliance. Then you need to remove any doors or panels that could be blocking getting to the pilot light. Follow the instructions on the front of the light to open the pilot light tube. After you've re-lit your pilot light, return the gas valve knob to the "on" position.
Safety is the primary reason to keep a pilot light lit. If you accidentally shut off the pilot light, gas constantly venting from the tube can build up in your home until the spark or static electricity sparks the gas, Gas Patio Heater Regulator causing an explosive explosion. Pilot tubes are designed to contain a built-in cutoff valve that can keep this from happening.
A constantly burning pilot light is not only dangerous however, it also consumes energy. A pilot light burns between $7 and $18 worth of gasoline per month, according to various studies. This waste of fuel also puts more strain on the air conditioning system during summer use. Another issue with a pilot light is that it can attract spiders, which can spin webs that can clog pilot tubes. A constant flame can emit small amounts of the compound Mercaptan, which is the cause of the smell of rotten eggs that is common in natural gas. If you're ever concerned about these issues, consider purchasing a gas fireplace with a remote control or replacing your fireplace with a more efficient and modern model.
