Table 501.4.2 Makeup Air Opening Sizing Table for New and Existing Dwelling Units IFGC Appendix E, Worksheet E-1 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.
