A. Use this column if there are other than fan-assisted or atmospherically vented gas or oil appliance or if there are no combustion
appliances. (Power vent and direct vent appliances may be used.)
B. Use this column if there is one fan-assisted appliance per venting system. (Appliances other than atmospherically vented appliances
may also be included.)
C. Use this column if there is one atmospherically vented (other than fan-assisted) gas or oil appliance per venting system or one solid
fuel appliance.
D. Use this column if there are multiple atmospherically vented gas or oil appliances using a common vent or if there are
atmospherically vented gas or oil appliances and solid fuel appliances.
Directions - In order to determine the makeup air for ventilation, Table 501.4.1 must be filled out (see below). For most new installations, column A will be
appropriate, however, if kitchen hoods exceed 300 cfm, atmospherically vented appliances or solid fuel appliances are installed, use the appropriate column. Please
note, if the makeup air quantity is negative, no additional makeup air will be required for ventilation, if the value is positive refer to Table 501.4.2 and size the
opening. Transfer the cfm, size of opening and type (round, rectangular, flex or rigid) to the last line of section D. The ventilation make-up air supply must
communicate with the exhaust appliances.
Table 501.4.1, 2015 Minnesota Mechanical Code
PROCEDURE TO DETERMINE MAKEUP AIR QUANITY FOR EXHAUST APPLIANCES IN DWELLING UNITS
(Additional makeup air will be required for combustion appliances, see KAIR method for calculations)
Be advised: 2015 Minnesota Mechanical Code, Section 505.2, Installation of exhaust hood systems capable of exhausting in excess of 400 cfm shall be provide with
makeup air at a rate approximately equal to the exhaust air rate. Such makeup air systems shall be equipped with a means of closure and shall be automatically
controlled to start and operate simultaneously with the exhaust system.

Notes:
A. 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.
B. If flexible duct is used, increase the duct diameter by one inch. Flexible duct shall be stretched with minimal sags. Compressed
duct shall not be accepted.
C. Barometric dampers are prohibited in passive makeup air openings when any atmospherically vented appliance is installed.
D. Powered makeup air shall be electrically interlocked with the largest exhaust system.

Explanation - If no atmospheric or power vented appliances are installed, check the appropriate box, not required. If a power vented or atmospherically vented
appliance installed, use IFGC Appendix E, Worksheet E-1 (see below). Please enter size and type. Combustion air vent supplies must communicate with the
appliance or appliances that require the combustion air.
Not Required
Directions - The Minnesota Fuel Gas Code method to calculate to size of a required combustion air opening, is called the Known Air Infiltration Rate Method (KAIR).
For new construction, 4b of step 4 is required to be filled out. The example assumes a typical 3,000 square foot home with a finished basement that has a
mechanical room that is 10 feet wide by 12 feet long with an 8 foot ceiling. It also assumes installation of a 70,000 btu, 2 pipe condensing furnace; and a 40,000 Btu,
power vented water heater.

Residential Combustion Air Calculation Method

Step 4: Determine Required Volume for Combustion Air.
4a. Standard Method
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.
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).
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
__ Draft Hood (Non- fan assist) __ Fan Assisted & Power Vent __ Direct Vent _X_Electric
Total Btu/hr input of all combustion appliances (DO NOT COUNT DIRECT VENT APPLIANCES)
Use Standard Method column in Table E-1 to find Total Required Volume (TRV)
Step 6: Calculate Reduction Factor (RF).
(DO NOT COUNT DIRECT VENT APPLIANCES)
Use Fan-Assisted Appliances column in Table E-1 to find Required Volume Fan Assisted (RVFA)
Total Btu/hr input of all non-fan-assisted appliances
Use Non-Fan-Assisted Appliances column in Table E-1 to find Required Volume Non-Fan-Assisted (RVNFA)
Total Required Volume (TRV) = RVFA + RVNFA
1 If desired, ACH can be determined using ASHRAE calculation or blower door test. Follow procedures in Section G304
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
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)
Combustion Air Opening Area (CAOA): Total Btu/hr divided by 3000 Btu/hr per in2
Step 8: Calculate Minimum CAOA.
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)
