NFI Exam Review
________ ignites at a lower attention - ANS-propane
1 bushel (56 pounds) of premium heating corn provides an energy output of ANS-7600
BTU/lb. 10 foot/2 foot/3 foot rule - ANS-at least three feet higher than the roof opening
at least 2 feet higher horizontally than every other structure within 10 toes of the chimney. 2
sorts of manufacturing facility built fireplaces - ANS-radiating and circulating
3 Ts of performance - ANS-Temperature, turbulence, time
capacity of the vent to keep heat (draft) - ANS-gases cool, grow to be much less buoyant,
lose warmness to chimney partitions, double partitions, or insulated has vents.
Air Inlets (pellet) - ANS-may also terminate at applice and bring room air (may additionally
enlarge to outdoor air source, and might blend room and outside air)
promises number one air to burn pot
promises secondary air for fuel combustion air to fuel ratio is a - ANS-vital aspect in
obtaining most reliable gasoline combustion
Aldehydes - ANS-chemicals that have a robust stinky smell
Aldehydes end result from - ANS-flame impingement and thru the presence of contaminated
air
All vented gas fireplaces MUST have - ANS-an automatic gas ignition machine with safety
shutoff
ANSI - ANS-American National Standards Institute
ANSI Z21.Eleven.2a - ANS-appliances -fireplaces, fireplace inserts, freestanding stoves
required - protection pilot with ODS
regulations - bedroom, rest room, constrained areas, tight construction, max forty,000
BTU/hr output, authority having jurisdiction
options - listed blowers, thermostats
ANSI Z21.60, CSA 2.26 - ANS-home equipment - log units
obstacles: no thermostat alternatives - listed blowers
requirements - protection pilot, running hearth chimney, permanent damper beginning,
fireside screen, cleansing of venting gadget
Ash recepticals - ANS-some sealed (limits air leakage)
some permit controlled quantity of air
ash elimination CRITICAL
- obstructs air intakes - accumulation on blower, heat exchanges, and venting systems
Ash traps - ANS-spaces to seize fly ash
get entry to through panels
ordinary cleaning is critical
- lessen building up on warmth exchangers and vents
ASTM - ANS-American Society for Testing and Materials
Auger system (pellet) - ANS-gasoline feed manage mechanism (precise velocity and
durations, adjusted to length and density of pellets, and allows combustion air changes)
backup emergency heating - ANS-for electricity outages, both a limited area or capacity to
supply primary heat
Bottom feed prevention strategies include: - ANS-excessive temperature restriction switch
or thermistor on auger tube (isolation of auger tube)
, BTU - ANS-British Thermal Unit, The amount of strength had to warmness one pound of
water one degree Fahrenheit
Built-in, high-performance fireplaces, or ANSs, are encased in an insulated metallic
cupboard and feature efficient combustion and convection chambers. Can be enclosed in
close proximity to combustibles
butane lighter temp - ANS-3,2 hundred F
Carbon monoxide is ________ while aldehydes are present - ANS-gift
Carbon monoxide is risky due to the fact (aside from senseless) - ANS-it mixes with blood
and decreases oxygen wearing ability
Cast Iron (fireplace) - ANS-crafted from molds, may be ornamental
Catalyst - ANS-substance that modifies, particularly will increase, the rate of chemical
response with out being fed on in the technique
The problem of keeping a high fuel ignition temperature is conquer by means of the
catalyst-equipped appliance (ANS). Catalyst Equipped Appliances - ANS-catalytic
combustors extensively reduce emissions and creosote formation and feature a better
efficiency score
Catalyst Equipped Appliances typically includes - ANS-ceramic or chrome steel substrate
blanketed with a excessive surface area wash coat and the catalyst usually constructed from
platinum or palladium
Chemical reactions of catalysts - ANS-takes place at a decrease strength degree than
usually essential
Chimney - ANS-premiere performance is carried out whilst vent size fits appliance flue
outlet length
Chimney Chase - ANS-Conceals chimney
Interior location first-class
Insulate (stable to keep away from sagging or contact with chimney, no blown insulation
except covered wall hollow space, and seal gaps around framing)
Fire stops can be required at all ground/ceiling stages
Chase reduce via eaves should no longer be open to attic
Chimney Height - ANS-10 foot/2 foot/3 foot rule
Chimney not only eliminates exhaust but also answerable for - ANS-presenting combustion
air that starts offevolved and sustains the fire
cigarette temp - ANS-500-800 F
circulating layout - ANS-adds function of warmth switch via heated air convection with the
aid of circulating air round the fire chamber and releasing into area to be heated through
grills and louvers
Clean out beginning IRC - ANS-opening within 6" of base of 5 and six" at lowest chimney
commencing
minimum top of 6"
non-flamable cowl
Clean out starting NFPA 211 - ANS-secure, tight ultimate, non-combustible doors and
frames
minimum sixteen" above floor degree or grade
no obstructions within 18"
Clearences - ANS-described area between a warmth producing floor and combustible
material
