E. An equivalent length of 100 feet of round smooth metal duct is assumed. Subtract 40 feet for the exterior hood and ten feet for each 90-degree
elbow to determine the remaining length of straight duct allowable.
F. If flexible duct is used, increase the duct diameter by one inch. Flexible duct shall be stretched with minimal sags.
G. Barometric dampers are prohibited in passive makeup air openings when any atmospherically vented appliance is installed.
H. Powered makeup air shall be electrically interlocked with the largest exhaust system.

Residential Combustion Air Calculation Method
(for Furnace, Boiler, and/or Water Heater in the Same Space)
Step 1: Complete vented combution appliace information:
Furnace/Boiler:
Draft Hood Fan Assisted Direct Vent Input: Btu/hr
(Not fan Assisted) & Power Vent
Water Heater:
Draft Hood Fan Assisted Direct Vent Input: Btu/hr
( Not fan Assisted) & Power Vent
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: ft3
Step 3: Determine air Changes per Hour (ACH)1
Default ACH values have been incorporated into Table E-1 for use with Method 4b (KAIR Method). If the year of construction
or ACH is not known, use method 4a (Standard Method).
Step 4: Determine Required Volume for Combustion Air.
4a. Standard Method
Total Btu/hr input of all combustion appliances (DO NOT COUNT DIRECT VENT APPLIANCES) Input: Btu/hr
Use Standard Method column in Table E-1 to find Total Required Volume (TRV) TRV: 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.
4b. Known Air Infiltration Rate (KAIR) Method
Total Btu/hr input of all fan-assisted and power vent appliances
(DO NOT COUNT DIRECT VENT APPLIANCES) Input: Btu/hr
Use Fan-Assisted Appliances column in Table E-1 to find
Required Volume Fan Assisted (RVFA) RVFA: ft3
Total Btu/hr input of all non-fan-assisted appliances Input: Btu/hr
Use Non-Fan-Assisted Appliances column in Table E-1 to find
Required Volume Non-Fan-Assisted (RVNFA) RVNFA: ft3
Total Required Volume (TRV) = RVFA + RVNFA TRV = + = 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.
Step 5: Calculate the ratio of available interior volume to the total required volume.
Ratio = CAS Volume (from Step 2) divided by TRV (from Step 4a or Step 4b) Ratio =
Step 6: Calculate Reduction Factor (RF).
RF = 1 minus Ratio RF = - =
Step 7: Calculate single outdoor opening as if all combustion air is from outside.
Total Btu/hr input of all Combustion Appliances in the same CAS (EXCEPT DIRECT VENT) Input: Btu/hr
Combustion Air Opening Area (CAOA):
Total Btu/hr divided by 3000 Btu/hr per in2 / Btu/hr per in
2 = in2
Step 8: Calculate Minimum CAOA.
Minimum CAOA = CAOA multiplied by RF Minimum CAOA = x = in2
Step 9: Calculate Combustion Air Opening Diameter (CAOD)
CAOD = 1.13 multiplied by the square root of Minimum CAOA CAOD = 1.13 x Minimum CAOA = in
1If desired, ACH can be determined using ASHRAE calculation or blower door test. Follow procedures in Section 304.
CAOA =
