CSIA EVALUATION TEST ANSWERS AND QUESTIONS
SET A+
✔✔What is "pyrolysis"? - ✔✔The chemical alteration of wood as a result of the
application of heat
✔✔Perfect combustion results in: - ✔✔Only Co2 and water vapor
✔✔Creosote formation: - ✔✔Tar fog or droplets of liquids condense in the venting
system
✔✔Residence time - ✔✔length of time smoke remains in the chimney
✔✔Magnetic thermometers only display about __% of actual flue temp - ✔✔50%
✔✔Creosote should be removed because... - ✔✔Fire risk,
corrosive to steel, connectors, and mortar
✔✔Why should flashing be embedded in mortar? - ✔✔prevent leaks
✔✔Baffle location and purpose? - ✔✔Located between the firebox and flue collar.
Purpose is to complete better combustion
✔✔What does the barometric draft regulator do? - ✔✔Prevents excessive draft
✔✔Smoke chamber height SHALL NOT be greater than the ______ ______ of the
fireplace fire chamber. - ✔✔Inside width
✔✔Combustion needs... - ✔✔Heat, Oxygen, and Fuel
✔✔Nominal dimensions can vary by how much? - ✔✔Nominal dimensions vary by 1/2"
✔✔What is combustion? - ✔✔The rapid oxidation of fuel producing heat and light.
, ✔✔Parging the smoke chamber improves FLOW by... - ✔✔Reducing turbulence, and
eliminating corbeling
✔✔Connector dampers should not block greater than ___% of the connector when
closed. - ✔✔80%
✔✔Heat reclaimer / extractor - ✔✔Fits inline with connector, and is NOT to be used with
wood burning
✔✔What inspection level determines if a wall pass-through is installed properly? -
✔✔Level 2
✔✔Hearth stove should only be connected to... - ✔✔A properly built masonry fireplace
✔✔What problems are created when mortar joints between flue tiles are not smoothed?
- ✔✔May create turbulence and increased residence time of exhaust.
✔✔3 Positive aspects of Cast-in-Place liners - ✔✔1. adds structural integrity to chimney
2. resists corrosive deposits
3. able to support any fuel or appliance when sized properly
✔✔What never to do to a blocked passage in a chimney? - ✔✔Never pound from above
with a weight. (Might block so bad opening a wall is necessary to remove buildup)
✔✔True or false: A flat wire brush is hardest to reverse because of size and thickness
of bristles. - ✔✔True
✔✔1st choice of brush for oil passage flues and why? - ✔✔Polypropylene (plastic)
because they do not corrode or degrade from corossive deposits
✔✔The best brush to remove glaze in the flue? - ✔✔A chain brush / rotary
✔✔Main purpose of a vacuum - ✔✔To collect dust
✔✔Two purposes of a ridge hook - ✔✔1. Keep footing of slippery / fragile roofs
2. Allow acces on steep roofs
✔✔Why use an aluminum ladder? - ✔✔Lighter and less expensive over fiberglass
✔✔Respirator protects from what 4 things... - ✔✔gases, dust, vapors, disease from
animals
