This is system#_L_of_L—systems altered in this house. Copies to: Homeowner, HERS Rater, and Building Department Duct Leakage test Results Lif duct testing is required per CF-1 R-ALT form Step 1-Pre test:Leakage of the s tem before any alterations. This test is optional and is only used for the 60%reduction option 1 Pre-test leakage: CFM25 2 1 Line 1 x 0.4= t for 60%reduction Step 2-Determine Total System Fan Flow: Use any of these methods.Use values for equipment after alterations. 3 Cooling: Condenser tonnage: 3 tons x 400 CFM/ton= I ILOrJ JCFM 4 Heating: Furnace output: Btuh x.0217 CFM/Btuh= FM 5 Measured:(refer to ACM Manual Appendix RE,section 4.1)= JCFM 6 Measurement method: ❑flow hood ❑ plenum pressure matching ❑flow grid 7 Totals stem fan flow value to be used: FM may use highest of lines 3,4,or 5. Step 3-Determine Targets: Ba Total System fan flow(line 7 from above)x 0.06= FM25=6%leakage target(new duct systems) Bb Total System fan flow(line 7 from above)x 0.15= FM25=15%leakage target 9 Total S stem fan flow line 7 from above x 0.10= FM25=10%leakage to o to et I tep 4-Alterations:Must be consistent with the CFA R form. 10 ❑ Seal all new connections with approved materials. 11 ❑ No newly constructed portions of the system can have unducted building cavities to convey tem a 12 ❑ If adding or replacing more than 40 feet of duct,insulate new ducts per package D for that mate zone Step 5-Final Leakage(regular duct leakage test,for 15%total and 60%reduction) I , 13 leakage= I ICFM25 refer to 2005 ACM appendix RC,Sections RC 4. .1 4a ❑ if line 13 is less than line 8a house passes the 6%leakage requirement,Go to Ste 9. 4b ❑ If line 13 is less than line 8b house passes the 15%leakage requirernent.Go to Step 9. 15 ❑ If line 13 is less than line 2 house passes the 60%reduction requirement continue. / 16 ❑ If either of lines 14a,14b or 15 are checked,HERS verification is required. Sampling can be u 17 ❑ Ilf line 15 is checked,but not 14a or 14b,Smoke Test and Visual Inspection of Accessible Duct S ling is regw Step 6-Leakage to Outside: Similar to a regular duct blaster test but the house is pressurized to 25 pascals ait'lke same time. 18 leakage= I ICFM25 refer to 2005 ACM appendix RC,Sections RC 4.3.3 19 ❑ If line 18 is less than line 9 house passes the 10%leakage to outside requirement 20 ❑ If line 19 passes,HERS verification is required. Sampling can be used. Step 7-If the house does not pass any of lines 14,15 or 19. 21 ❑ ISmoke Test and Visual Inspection of Accessible Duct Sealing is required. See Step 8. 22 ❑ linstall required label per ACM Appendix RC,Sections RC.4.3.5. Step 8-Smoke Test and Visual Verification See 2005 Residential ACM Appendix RC Sections RC 4.3.5-7 23 ❑ Perform smoke test per ACM Appendix RC Sections RC 4.3.6. 24 ❑ Perform Visual Inspection and repair of excessively damaged ducts per ACM Appendix RC,Sections RC 4.3.7. 25 ❑ Seal r isle-boots to surrounding material per ACM Appendix RC,Sections RC 4.3.7. HERS Verification 26 ❑ If line 14 is checked. 15%leakage to be verified by HERS rater. Sampling is allowed. 27 ❑ If line 15 is checked. 60%leakage reduction to be verified by HERS rater(post test only)AND Smoke Test and Visual Verification to be performed by HERS Rater. Sampling is allowed. 28 ❑ If line 19 is checked. 10%leakage to outside to be verified by HERS rater. Sampling is allowed. 29 ❑ If none of lines 14,15 or 19 are checked Smoke Test and fix all accessable leakes. No sampling allowed. Sampling-Onl if house passes on lines 14,15 or 19. 30 ❑ 1.)Homeowner chooses to be put into a group of homes for random third party HERS sampling. 12.)Homeowner,installer and rater must sign the three-party agreement. 3.)All above tests must be completed by the installer or their representative,not the thins party rater. No Sampling-House does not pass by lines 14,15 or 19;OR homeowner chooses not to be part of a sample group 31 ❑ 1.)House to be tested by a third party HERS rater selected by installer. 2.)Homeowner,installer and rater must sign the three-party agreement. 3.)All above tests may be completed by the installer or their representative,and then verified by a third party rater. OR all above tests may be performed solely by the third party rater. 32 ❑ 1.)House to be tested by third party HERS rater selected by homeowner. 2.)All above tests may be completed by the installer or their representative,and then verified by a third party rater. OR,all above tests may be performed solely by the third party rater.
