Valve system uses a 24 VAC powered hot surface pilot gas igniter to ignite the pilot gas. A pilot gas burner ignites the main gas in both instances. Valve system is self-contained, thus eliminating the need for a separately mounted ignition source.

How do you adjust the pilot pressure on a gas valve?
To reduce pilot pressure, turn the pilot adjust screw clockwise. It is not recommended to adjust the screw beyond the limits that it can handle.
What happens if furnace gas pressure is too low?
Low pressure leads to rough ignition and overall poor combustion. The amount of wear and tear on your engine can be accelerated by overfiring the heat exchanger, which can be caused by high pressure. If your furnace is running at a lower pressure than it should be, you should check the pressure gauge to make sure it is not reading too low. If the gauge is reading low, then you need to increase the furnace pressure.
You can do this by turning the ignition switch to the “on” position, and then turning it back to “off”. If you do not see a change in pressure when the switch is turned off, it means that the temperature of the gas is too high.
This can be caused by a number of things, but the most common cause is a faulty thermostat, which can cause the heater to run too hot or too cold depending on how much pressure is being applied to it. Another cause of a high or low temperature is the type of furnace you are using. Some furnaces are designed to operate at higher temperatures than others.
Can I adjust the pilot light flame?
If the pilot flame is too small, you can adjust it by turning the pilot adjustment screw on the valve control. If you can’t get the screw to turn, then you’ll have to adjust the flame by hand. To do this, turn the control screw clockwise and then counterclockwise until you reach the desired flame size. You may need to use a pair of pliers or a small flat-head screwdriver to hold it in place.
Once you’ve reached the size you want, tighten the screws until they are tight and secure. Once your flame has been adjusted to the correct size, it’s time to tighten up the valves. The valve adjustment screws are located on either side of the throttle body. Tighten them all the way down, but don’t overdo it. Too much pressure will cause the engine to overheat, which can lead to engine damage.
How do I adjust the flame on my furnace?
To adjust the height of the pilot flame, turn the flame adjustment screw until the flame is from 1 1/2 to 2 inches (3.8 to 5.1 centimeters) high. If the control has an adjustment screw, it is located near the gas valve on the pilot assembly. Adjustment screws are located on both the left and right side of each pilot.
Adjustment screw #1 is the same as the one used to adjust pilot #2, but it is not necessary to turn it until you are sure that you have reached the correct height. If you do not have a screwdriver handy, you can use a small flat-head screw driver (not included) to loosen and tighten the adjustment screws. Be careful not to over-tighten the screws, as this can cause the fuel to leak from the tank and cause a fire.
Can a pilot light be too high?
So, if your pilot light flame also tends to be too high, ensure that your fireplace doesn’t have a button to bring the flame up or downward. It will reduce the fire if it is turned clockwise while it will increase the heat if it is turned the opposite way.
What happens if gas pressure is too high?
It’s just as bad for your furnace if it has high gas pressure. It greatly increases the risk of furnace overheating. All manner of internal components may become damaged when this happens. If you have a furnace that has been running for a long time, it may be time to replace it with a new one. This is especially true if it’s been in use for more than a few years.
What should your gas pressure be?
The natural gas pressure in the building gas piping between the gas meter and the appliance regulator needs to be at least 0.25 psi to operate correctly. If you have a gas pressure meter, you can use it to measure the pressure in your home. If you don’t have one, check with your local gas company to see if they can provide you with a pressure gauge.
How do I increase the pressure on my gas furnace?
Use a flathead screwdriver to turn the screw. While rotating it counterclockwise reduces the pressure, it raises it. If your furnace only has one pressure valve, you can remove the manometer and replace it with a pressure relief valve.
If you have two or more pressure valves, make sure they are all the same size, and that they all have a small hole in the bottom to allow gas to flow through them. This will help prevent gas from leaking out of one valve and into the other.
