Step 3: Determine Air Changes per Hour (ACHY. Default ACH values have been incorporated into Table E- I for use with Method 4b (I( AIR Method). If
the year of construction or ACH is not known, use method 4a (Standard Method).

Use Standard Method column in Table E- lto find Total Required Volume (TRV) put: — Btu/ f t ' TI If CAS Volume (from Step 2) is greater than TRV then no outdoor openings are needed. V: ft
If CAS Volume (from Step 2) is less than TRV then go to STEP 5.

Use Fan - Assisted Appliances column in Table E -1 to find
Required Volume Fan Assisted (RVFA) N
Total But/hr input of all non- fan - assisted appliances N
Use Non- Fan- Assisted Appliances column in Table E -1 to fmd N
Required Volume Non -Fan- Assisted N
Total Required Volume (TRV) = RVFA +RVNFA M

If CAS Volume (from Step 2) is less than TRV then go to STEP 5.
Step 5: Calculate the ratio of available interior volume to the total requir M

Ratio = CAS Volume (from Step 2) divided by TRV (from Step 4a or St
Step 6: Calculate Reduction Factor (RF).
RF= 1 minus Ratio

Combustion Air Opening Area (CAOA):
Total Btu/hr divided by 3000 Btu/hrper
Step 8: Calculate Minimum CAOA.
Minimum CAOA = CAOA multiplied by RF
Step 9: Calculate Combustion Air Opening Diameter (CAOD)
CAOD -1.13 multiplied by the square root of Minimum CAOA
