is filled with inert gas; and an oxygen-containing-gas supply adjusting step of adjusting the supply of the oxygen-containing gas such that combustion gas obtained after the combustion reaction of the start-up fuel and the oxygen-containing gas becomes the inert gas, which contains little oxygen...
The furnace filter should be replaced or cleaned at the beginning of the heating season and about once a month during periods of continuous use. To check the filter, take it out and hold it up to the light. If it looks clogged, replace it with a new filter of the same type and size...
In case you see that more than just a tip of the flame is yellow, try to adjust the fuel feeds. But if you still see that the flame is of the wrong color, or if you have problems with lighting the furnace, you’d better turn the gas off and call a professional to arrive and ex...
>Trace the gas by using a methane and nitrogen mixture. Use a gas-detection instrument to measure the level of carbon monoxide (CO) that is in the supply air plenum, exhaust flue, or the area around the furnace. Check the pressure in the heat exchanger by using a magnehelic gauge test...
which will re-start the flow of gas to the pilot. Strike up your match or lighter. Depress the reset button, and while it is depressed, hold the match flame near the pilot opening. When the pilot is burning brightly, release the rest button. The furnace will then start, automatically. ...
to freeze. The gas is much colder because there’s not enough of it to fill the coils; the gas over-expands inside the coils, resulting in lower pressure & lower temperature, hence freezing. TheJoule Thomson Effect(highly technical) describes the process. These N style evaporator coils are ...
Step 1:Check the bulb to see if it is burned out. If not, depress the push button on the door switch. Step 2:If the light stays on, clean the switch with a cloth. Then remove the switch from the jamb. Remove retaining screws hidden by a plastic trim piece, pry the switch out of...
1/2 HP motor is the most commonly used motor size in gas furnaces. We can use this information to both calculate how much electricity will a gas furnace spend per month, as well as adequately size a generator needed to power a gas furnace in the event of a power outage: ...
Checking Gas Pressure Now that you know what to do to keep yourself safe, you can gather the tools you need to check the gas pressure: a gas pressure manometer and a flat head screwdriver. First, make sure the gas switch for the fireplace is off. Look for two taps with screws marked ...
