ANSWERS GUARANTEE A+
✔✔The pump on a residential gun type oil burner is a blank pump - ✔✔Single stage or
two stage
✔✔The fuel oil enters a orifice of the novel through the - ✔✔Swirl chamber
✔✔The circular direction of the air in the air tube is in blank direction as the fuel oil
motion - ✔✔The opposite
✔✔The ignition transformer steps up the 120 V residential voltage to approximately
blank V. - ✔✔10,000
✔✔The stack switch or relay - ✔✔Has hot contacts that close when the temperature of
the fuel pipe rises
✔✔A cad cell is a safety device that - ✔✔Senses light in the combustion chamber
✔✔A booster pump is often needed when the oil supply tank is blank below the oil
burner - ✔✔15 ft
✔✔An oil deaerator - ✔✔Allows a one pipe oil delivery system to operate as a two pipe
oil delivery system
✔✔A fuel line filter is located between the - ✔✔Supply tank and the pump
✔✔The heat exchanger in a forced air oil fired furnace - ✔✔B- Transfers heat from the
flue gases to the air to be heated and circulated and keep them separate
✔✔The condensing oil furnace achieves part of it higher efficiency because of a blank
exchange - ✔✔B- Latent heat
✔✔Access air is supplied at the burner to ensure that there will be - ✔✔B- Enough
oxygen for complete combustion
✔✔How much access air is typically supply to the system to ensure that complete
combustion occurs - ✔✔50%
✔✔To perform combustion efficiency test a whole must be made - ✔✔B- In the flue on
the furnace side of the draft regulator
, ✔✔The net stack temperature is - ✔✔B- The difference between the flue temperature in
the temperature of the air surrounding the furnace
✔✔And air temperature rise check is performed to determine - ✔✔C- Whether or not the
airflow is correct across the heat exchanger
✔✔Meters flow of fule oil into the chamber - ✔✔Nozzle
✔✔Generates over 10,000 votes needed for spark - ✔✔Ignition transformer

✔✔What color is #2 fuel oil - ✔✔Red
✔✔What material is in a cad cell that allows it to respond to light - ✔✔Camum sulfide
✔✔What is the response that a cad cell makes to change in light - ✔✔Produces more
resistance less light, less resistance more light
✔✔What would the symptoms be of a dirty cad cell - ✔✔Burner wouldn't start
✔✔What would the result of access oil in the combustion chamber be if it were ignited -
✔✔Overfiring
✔✔What would the symptoms of an open cad cell be - ✔✔Burner would not start
✔✔What would cause a cad cell to become dirty - ✔✔Soot
✔✔What is the pressure at which oil burner nozzles are rated - ✔✔100 psi
✔✔Why should fuel oil not be spilled - ✔✔Odor and could start a fire
✔✔What was the size of the pressure tap in the oil pump for the high-pressure gauge -
✔✔1/4, 1/8 depending on the unit
