We lr a trtati n with heat calc for 1251 and 12.53 Motherly Avenus,
in your city T t crtic that are cal .tulate are heating 2a 000 BTU's
and cooling is 10,500 1311` 1 ` , the smallest furnace i d a' unit that I have .
^lahle is afurnace with output of 3 and the ac anit is 18500,
meaning that the units according to guide lines exceed the 15% differential
that is allowed,
aritact d Scott who is itlr the date, He suited in sit odors
he one that are c re sing it i s allowable f r the local c :fal to
on the adju::stnrent of the oversized equipment.

Step 1: Complete vented combustion appliance information.
Furnace/Boiler:
❑ Draft Hood E Fan Assisted
(Not fan assisted) & Power Vent
Water Heater:
O Draft Hood rt3 Fan Assisted
(Not fan assisted) & Power Vent
Step 6: Calculate Reduction Factor (RF).
RF 1 minus Ratio
MINNESOTA FUEL GAS CODE
IFGC APPENDIX E (IFGS)
RESIDENTIAL COMBUSTION AIR CALCULATION METHOD
(FOR FURNACE, BOILER, AND WATER HEATER IN THE SAME SPACE)
❑ Direct Vent
❑ Direct 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.
Step 3: Determine Air Changes per Hour (ACH)'. Default ACH values have been incorporated into Table E -I for use with Method 4b (R MR Method). If
the year of construction or ACH is not ]mown, 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)
Use Standard Method column in Table E-1 to find Total Required 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
Total Btu/hr input of all fan - assisted and power vent appliances
(DO NOT COUNT DIRECT VENT APPLIANCES)
Use Fan - Assisted Appliances column in Table E -1 to find
Required Volume Fan Assisted (RVFA)
Total But/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
Total Required Volume (TRV)=RVFA + RVNFA
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)
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
Input: tu/hr
RVF t: hew ft'
Input: s Btu/lit
(RVNFA)RVNF C' ft'
TRV = t! 0C° + 0 l ft'
Ratio = IWO / 6 = 0:406
RF =1- ,e)6 = .1 1 1
CAOA = / ? ' 3000Btu/hr per in'= '1.,C33n''
Step 8: Calculate Minimum CAOA.
Minimum CAOA =CAOA multiplied by RF q' p o�(�
Minimum CAOA = 4 ; s / = �, �
Step 9: Calculate Combustion Air Opening Diameter (CAOD)
CAOD =1.13 multiplied by the square root of Minimum CAOA
CAOD =1.13 ��Iinimum CAOA =
If desired, ACH can be determined using ASHRAE calculation or blower door test. Follow procedures in Section G304.
