What is a Quality Control (QC) Inspection
an internal process of a weatherization agency focusing on the final
inspection.
What is a Quality Assurance inspection
a third party inspection that is usually employed by the state or DOE
How should CO be measured in an oven
at steady state, with an open window or while operating the exhaust hood.
When should ambient CO levels be monitored
upon entering the CAZ and during the testing of all combustion appliances
How long should you allow spillage before failing the appliance
60 seconds of spillage
At what ambient level ppm should you immediately stop testing
35 ppm
,What three things do you need to know to calculate the Base Ventilation
Requirement.
The total occupied square footage, the number of occupants (no pets), and
the number of bedrooms (then add 1)
The first step of 3 to calculating the BVR (Base Ventilation Requirement)
requires how many cfm per 100 sq. ft.?
1 cfm per 100 sq. ft. (divide total occupied square ft. by 100)
The second step of 3 to calculating the BVR (Base Ventilation Requirement)
is...
Determining which number of bedrooms+1 or number of occupants is higher,
then multiply by 7.5 cfm
The third step of 3 steps of determining the BVR (Base Ventilation
Requirement) is...
add the cfm's of step 1 & 2 together to calculate the total BVR (Base
Ventilation Requirement)
Find the BVR (Base Ventilation Requirement) of a 1452 sq. ft. home, with 3
people, 2 bedrooms.
37.02 cfm
, Find the BVR (Base Ventilation Requirement) of a 2050 sq. ft. home, with 4
people, 5 bedrooms.
65.5 cfm
Find the BVR (Base Ventilation Requirement) of a 1000 sq. ft. home, with 4
people, 3 bedrooms.
40 cfm
Find the BVR (Base Ventilation Requirement) of a 1000 sq. ft. home, with 3
people, 2 bedrooms.
32.5 cfm
How much ventilation is needed for a kitchen exhaust fan?
100 cfm
How much ventilation (cfm) is needed for a bathroom exhaust fan?
