For heat recovery ventilators (HRV) and energy recovery ventila‐ tors (ERV) the average hourly ventilation capacity must be determined in consideration of any reduction of exhaust or out outdoor air intake, or both, for defrost or other equipment cycling. Continuous ventilation ‐ A minimum of 50 percent of the total ventilation rate, but not less than 40 cfm, shall be provided, on a con‐ tinuous rate average for each one‐hour period. The portion of the mechanical ventilation system intended to be continuous may have automatic cycling controls providing the average flow rate for each hour is met. 16411 ABERDEEN ST NE,HAM LAKE, MN 55304 2 Section B Ventilation Method (Choose either balanced or exhaust) Balanced, HRV (Heat Recovery Ventilator) or ERV (Energy Recov‐ ery Ventilator) – cfm of unit in low must not exceed continuous venti‐ lation rating by more than 100%. Exhaust only (Continuous fan rating in cfm) Low cfm: High cfm: Continuous fan rating in cfm (capacity must not exceed continuous ventilation rating by more than 100%) Directions ‐ Choose the method of ventilation, balanced or exhaust only. Balanced ventilation systems are typically HRV or ERV’s. Enter the low and high cfm amounts. Low cfm air flow must be equal to or greater than the required continuous ventilation rate and less than 100% greater than the continuous rate. (For instance, if the low cfm is 40 cfm, the ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of each hour. Section C Ventilation Fan Description Location Continuous Intermittent Directions ‐ The ventilation fan schedule should describe what the fan is for, the location, cfm, and whether it is used for continuous or intermittent ventilation. The fan that is chose for continuous ventilation must be equal to or greater than the low cfm air rating and less than 100% greater than the continuous rate. (For instance, if the low cfm is 40 cfm, the continuous ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of each hour. Section D Ventilation Controls Directions ‐ Describe operation and control of the continuous and intermittent ventilation. There should be adequate detail for plan reviewers and inspectors to verify design and installation compliance. Related trades also need adequate detail for placement of controls and proper operation of the building ventilation. If exhaust fans are used for building ventilation, describe the operation and location of any controls, indicators and legends. If an ERV or HRV is to be installed, describe how it will be installed. If it will be connected and interfaced with the air handling equipment, please describe such connections as detailed in the manufactures’ installation instructions. If the installation instructions require or recommend the equipment to be interlocked with the air handling equipment for proper operation, such interconnection shall be made and described. 3 Section E Make‐up air Passive (determined from calculations from Table 501.3.1) Powered (determined from calculations from Table 501.3.1) Interlocked with exhaust device (determined from calculation from Table 501.3.1) Other, describe: Location of duct or system ventilation make‐up air: Determined from make‐up air opening table Cfm Size and type (round, rectangular, flex or rigid) Directions ‐ In order to determine the makeup air, Table 501.3.1 must be filled out (see below). For most new installations, column A will be appropriate, however, if atmospherically vented appliances or solid fuel appliances are installed, use the appropriate column. For existing dwellings, see IMC 501.3.3. Please note, if the makeup air quantity is negative, no additional makeup air will be re‐ quired for ventilation, if the value is positive refer to Table 501.3.2 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 make‐up air supply must be installed per IMC 501.3.2.3.

Section F Combustion Not required per mechanical code (No atmospheric or power vented appliances) Passive (see IFGC Appendix E, Worksheet E‐1) Size and type Other, describe: 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. Section F calculations follow on the next 2 pages. 5 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. For new construction, 4b of step 4 is required to be filled out. 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 combustion appliance information. Furnace/Boiler: Draft Hood Fan Assisted Direct Vent Input: ______________________Btu/hr or Power Vent Water Heater: Draft Hood Fan Assisted Direct Vent Input: ______________________Btu/hr or 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 L x W x H L W H 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. (DO NOT COUNT DIRECT VENT APPLIANCES) 4a. Standard Method Total Btu/hr input of all combustion appliances Input: Btu/hr Use Standard Method column in Table E‐1 to find Total Required TRV: ft3 Volume (TRV) 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 (DO NOT COUNT DIRECT VENT APPLIANCES) Total Btu/hr input of all fan‐assisted and power vent appliances Input: Btu/hr Use Fan‐Assisted Appliances column in Table E‐1 to find RVFA: ft3 Required Volume Fan Assisted (RVFA) Total Btu/hr input of all Natural draft appliances Input: Btu/hr Use Natural draft Appliances column in Table E‐1 to find RVNFA: ft3 Required Volume Natural draft appliances (RVNDA) Total Required Volume (TRV) = RVFA + RVNDA 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. 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 = 1 ‐ __________________=__________________ 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 Input: Btu/hr (EXCEPT DIRECT VENT) Combustion Air Opening Area (CAOA): Total Btu/hr divided by 3000 Btu/hr per in2 CAOA =___________________/ 3000 Btu/hr per in2 =_____________________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 √ Minimum CAOA = in. diameter go up one inch in size if using flex duct 1 If desired, ACH can be determined using ASHRAE calculation or blower door test.
