Oil Burners Test 2
Barometric - correct answer-sole purpose is to control over-fire draft (regulates chimney draft
pressure)
Bleed oil burner - correct answer-start gun, jumper f and f, with bleeder hose attached leave
open till air and froth is gone, then close bleeder
BTU input and output - correct answer-Give GPH- 1.0 gph x 140,000 btu= input
input x efficiency= output
Cad Cell - correct answer-new confirms by light safer- 14-45 seconds to prove flame
Choke - correct answer-located at the end of the tube, increases air velocity and establishes
low pressure right in front of nozzle
cloud point - correct answer-temperature at which wax crystals form
Combustion characteristics - correct answer-process of burning- viscosity, pour point, cloud
point, flash point
Constant transformer - correct answer-electrodes spark continuously, ign trans doesn't turn
off
Draft levels - correct answer-too high- letting too many btu's in chimney stack rather than the
heat exchanger
too low- incomplete combustion will and form soot
flash point - correct answer-temperature at which vapors escaping from the surface of the oil
can be momentarily ignited
Ignition Transformers - correct answer-two types constant and intermittent
intermittent - correct answer-light when call for heat (2 relays) only operates when burner is
started
primary 120 V
secondary 10,000 V
Net stack calculated - correct answer-insert temp probe into vent pipe before barometric in
the flue (400-800) then subtract room temp from it
new oil burner specs - correct answer-above 5/16
apart 5/32
in front of 1/16
Number 2 fuel oil characteristics - correct answer-140,000 btu/gal
