Economizer is an accessory of boiler that recovers the waste heat from the flue gas blown out of the boiler. Thus it actually "economizes" the operational cost or in other words, improves the efficiency of fuel utilisation in the boiler. The temperature of the flue gases ( the mixture of burnt fuel & air ) depends up on the steam pressure ( temperature more precisely ). Higher the steam pressure generated, the higher is the flue gas temperature. Economizer is a heat exchanger which exchanges heat between water ( which is fed in to the boiler ) & the flue gas. It means it increases the temperature of the feed water using the otherwise wasted heat of the flue gas. So the water entering the boiler has higher temperature compared to the one without this economizer. This higher temperature of water requires less amount of heat to generate steam so the operation becomes "economical". Similarly the economizer can also work to heat up the air entering the boiler through the flue gas heat, instead of heating the water.
Tramp Air is air that leaks in through faulty gaskets on clean out covers, doors, between boiler sections and around burner mounting flanges. Air that infiltrates into the heating appliance other than designed by the manufacture can be classified as tramp air; that dilutes flue gas temperatures. The composition of the flue gases is also diluted by tramp air. This retards the technicians ability to accurately monitor and control combustion conditions. Tramp air results in reduced efficiency.
Indiana has a long history with tobacco, particularly as a significant agricultural crop. In the 19th century, the state emerged as a leading producer of both flue-cured and burley tobacco, benefiting from its fertile soil and favorable climate. The tobacco industry contributed to the state's economy, providing jobs and supporting local farmers. However, health concerns and changing regulations have since led to a decline in tobacco cultivation and consumption in Indiana, reflecting broader national trends.
Any chimney should terminate at least 600mm above the ridge height. This is a minimum to comply with building regs. This is measured to the top of the pot. If the terminal is coming out of the "slope" of the roof and not the ridge, then at least 2.3m measured horizontally from the roof surface. These are to meet the minimum requrement of building control but in reality can differ with each installation. Things like neighbouring buildings, tall trees and locallity can all affect the working of the chimney, as can the internal size of the flueway and where it is located on the house itself. If the chimney is internally built, there is good insulation from the building itself to keep the flue gasses warm. If the chimney is on a gable end with only 4" of brickwork between it and the outside, then the movement of the flue gases will be slower due to them cooilng down. I would like to say that you should be confident in the advice given by getting a tradesperson that has the relevant certificates to do the job in question. but you would be better contacting the governing body in question (HETAS or GASafe for example) and getting the list of recommended installers.

The White House fire in 1929 was caused by a defective flue in a fire place chimney.
A FLUE is a chimney or vent. IE A flue was fitted to my central heating unit.
the blindness was caused by a serouis flue no one knew what the flue was called its the flue or a dezeez
A homophone for "flue" is "flew."
Jason Von Flue's birth name is Jason Lee Von Flue.
The flue is the actual pipe or chimney where the damper is the mechanism that opens and closes the flue
Chimney flue = Arubá (ארובה)
Jason Von Flue is 6'.
To determine if the chimney flue is open, shine a flashlight up the chimney and look for light coming through the flue. If you see light, the flue is open. If not, it may be closed.
flu (meaning sickness) flue (as in fireplace flue or vent)
Many types of flue dusts exist.
