Equation 11-1
(0.02 x square feet of conditioned space)+[15 x(number of bedrooms+1)]=Total ventilation rate(cfm)
Total ventilation—The mechanical ventilation system shall provide sufficient outdoor air to equal the total ventilation rate
average,for each one-hour period according to the above table or equation. For heat recovery ventilators(HRV)and energy
recovery ventilators(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 continuous 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.
Section B
Ventilation Method
(Choose either balanced or exhaust only)
Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Recovery ❑ Exhaust only
Ventilator)—cfm of unit in low must not exceed continuous Continuous fan rating in cfm
ventilation ratingby more than 100%.
Low cfm: GO High cfm: oo Continuous fan rating in cfm(capacity must not exceed
J 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 airflow 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 Schedule
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
(Describe operation and control of the continuous and intermittent ventilation)
HRV balanced on low speed to 50cfm
HRV balanced on high speed to 1 00c
Directions-Describe the operation of the ventilation system.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.

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.
Section F calculations follow on the next 2 pages.
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: 44000
raft Hood Dan Assisted ✓krect Vent Input: Btu/hr or Power Vent
Water Heater: 40000
raft Hood F✓ Fan Assisted Direct Vent Input: Btu/hr or Power Vent
Electric per energy certificate
Step 2:Calculate the volume of the Combustion Appliance Space(CAS)containing combustion appliances.
252
The CAS includes all spaces connected to one another by code compliant openings. CAS volume: ft3
LxWxH ®L 7]WE]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: 40000 Btu/hr
Use Fan-Assisted Appliances column in Table E-1 to find RVFA: 3000 ft,
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= 3000 _+ 0 3000 TRV ft
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= 252 / 3000 = 0.08
Step 6:Calculate Reduction Factor(RF).
RF=1min us Ratio RF=1- 0.08 - 0.92
Step 7:Calculate single outdoor opening as if all combustion air is from outside. 40000
Total Btu/hr input of all Combustion Appliances in the same CAS Input: Btu/hr
(EXCEPT DIRECT VENT)
Combustion Air Opening Area(CAOA): 1 3.33
Total Btu/hr di vid ed by 3000 Btu/hr per int CAOA= 40000 /3000 Btu/hr per int= int
Step 8:Calculate Minimum CAOA.
Minimum CAOA=CAOA multiplied by RF Minimum CAOA= 13.33 x 0.92 = 12.21 int
Step 9:Calculate Combustion Air Opening Diameter(CAOD)
CAOD=1.13 multiplied by the square root of Minimum CAOA CAOD=1.13 V Minimum CAOA= 3.95 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.Follow procedures in Section
