Step 2: Calculate the volume of the Combustion Appliance Space (CAS) containing combustion appliances.
The CAS includes all spaces connected to one another by code compliant openings. CAS volume:,N t3
Step 3: Determine air Changes per Hour (ACH)i
Default ACH values have been incorporated into Table E-1 for use with Method 4b (KAIR Method). If the year of construction

Step 4: Determine Required Volume for Combustion Aa.

Use Standard Method column in Table E-1 to find Total Required Volume (TRV) TRV: $d00 ft3
If CAS Volume (from Step 2) is greater than TRV then no outdoor openings are needed.
If CAS Volume (from Step 2) is less than TRV then go to STEP 5.

lfC olume (from Step 2) is greater than TRV then no outdoor openings are needed.
CAS Volume from St 2 is less than TRV then go to STEP 5.
Step 5: Calculate the ratio of available interior volume to the total required volume,
Ratio = CAS Volume from St 2 divided by TRVfrom Step4a or Step 4b Rabb = / -
Step 6: Calculate Reduction Factor (RF).
RF =1 minus Ratio RF =1 - -
