Try loosening the nut on the underside of the valve slightly try to turn it. You may need to tighten the nut again when done.

Natural gas has a chemical called Mercaptan the human nose can detect this at ~1 part per billion so probably not that. Excess carbon dioxide the stuff you exhale can cause your symptoms and newer tightly sealed homes can allow the carbon dioxide to build up. You may have make up air on your furnace a small amount drawn in from outside. Because of dirty air ...

There are combined CO/NG detectors, very cheap. The best NG detector is your nose. Your air filter will not filter either of these gases, they will pass through. If you have an electrostatic air filter it might set NG aflame .... that would certainly alert you to it. The stuff in your air filter could be grey, black, brown, white ... it really depends ...

The feed through a foundation or wall in my state requires a listed flanged pipe. I don’t know what the coating is but there is a coating to prevent corrosion from contact with cement products. The flange prevents movement of the earth causing a failure inside the home but I live in a seismic zone so movement is a possibility. Would I go back and update an ...

Sounds like extra charge. There is normally little movement and little of no force pushing the pipe against the mortar. Presumably the gas line is buried and experiences only small temperature changes to cause longitudinal movement movement ( radial movement would be essentially zero). Putting foam rubber insulation on the exposed pipe is bad. Rain wets it ...

The capillary is the small regulating tube if you cut it with side cutters it may partially seal keep this side of the system on the high side so you don’t loose all the oil. If the cap tube is on the low side it will spray oil at what ever pressure It is charged to. If it partially is sealed and a slow release this helps prevent the loss of the oil that a ...

Venting a flammable gas may be safe as long as there are no sources of ignition in the area and the gas has time to dissipate. Kind of like having a propane or LP gas cylinder filled once the cylinder is full they vent the gas between the pipe and fill valve. Outside away from ignition sources this is considered safe so I would expect the same to be true ...
