When a gas furnace ignites and is under full-fire why does the fan not come on immediately?
The fan delay is designed to allow the heat exchanger to warm up before the fan blows air into the ducts. This helps increase efficiency and prevents cool air from being circulated initially. Once the heat exchanger reaches the set temperature, the fan will turn on to distribute warm air throughout the home.

How does a furnance work?
The BurnerThe heart of a gas furnace is the burner. Most gas furnaces have two or more burners controlled by a thermostat. When the temperature in the house falls below a certain level, gas begins to flow and an electronic ignition system ignites it. This hot, combusted gas rises past a heat exchanger and out through a vent that leads to the outside of the house. Air CirculationA motor in the gas furnace pulls in air from an exchange -- a large flat grill in the floor, ceiling, or wall of a house. That air flows through ducts into the plenum of the furnace. The plenum is on the opposite side of the heat exchanger from the burner. Heat from the combusted natural gas warms the air as it passes by. The warm air is then taken back into the house through ducts that run to vents. Many houses have vents in every room. MaintenanceModern gas furnaces are very efficient when their first installed, but that efficiency can rapidly decline. New furnaces often come with flimsy air filters which break down quickly. If the filters are not replaced, dirt gets into the air ducts. Ducts can also pull apart at their joints, leaving leaks. This decreases the efficiency of the whole system, because hot air can leak out under the house. Fortunately, most duct leaks can be fixed with simple HVAC tape. One of the most common problems in older furnaces is dirty burners. As grime accumulates over time, the burner becomes less efficient. It produces less heat and doesn't completely burn the gas, resulting in a colder house and higher heating bills. Fortunately, many burners can be cleaned with nothing but a wire brush.
Is striking a match an example of heat produced by friction?
yes. because when two objects rub together it produces heat and friction, im pretty sure. A: I would respectively disagree with the answer given above and say "no." Matches use a compound chemical that ignites under minimal friction, but this friction is not relative to the heat produced (in fact the first attempts were unsuccessful, as not enough heat was produced to ignite the substance). In my humble opinion the match is only an example under the broadest of terms.
If you touch a hot stove what happens?
If you touch a hot stove, you will likely experience burning pain due to the heat. This happens because the high temperature of the stove causes damage to your skin cells, resulting in a burn. It is important to immediately remove your hand from the stove, run it under cold water, and seek medical attention if the burn is severe.
What is the advantage of a standing pilot for a furnace located under a house?
A standing pilot light provides a continuous small flame that is used to ignite the main burner when the thermostat calls for heat. This ensures reliable ignition, making it suitable for locations with potential airflow issues or where electricity supply may be unreliable. Additionally, a standing pilot system can provide heat during power outages when other ignition systems reliant on electricity may not function.
How much is the letter e you are now viewing under the scanner magnified under the LPO under the HPO?
The letter "e" is magnified twice under the LPO and twice again under the HPO, resulting in a total magnification of four times under both lenses.
How can I prevent water from accumulating under my furnace?
To prevent water from accumulating under your furnace, ensure proper drainage by checking and clearing any blockages in the condensate line, maintaining a level surface for the furnace, and installing a condensate pump if necessary. Regularly inspect and maintain your furnace to prevent leaks and water damage.

Is the furnace covered by homeowners insurance?
Yes a furnace is covered property under a homeowners insurance policy. However, the key to whether the policy will pay for damage is the cause of the damage. This is always the key to coverage.
How is iron refined?
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie

Does a Viscount serve directly under an Earl?
In the British nobility, a viscount is ranked immediately above a baron and immediately below an earl. I doubt whether a viscount would "serve under an earl" as you put it.
