KNIPE City Engineer JOHN V. GILLESPIE Chief of Police RICHARD T. HARE City Treasurer SUBJECT: Chimney Terminations at Pardee Construction Background On April 3, 1991 the City Council heard public comment on the chimney terminations at Pardee's development area. Untested "shrouds" have recently been removed from many of these homes. This removal improves the safety of the terminations but alters the appearance of the homes. Council directed staff to report on the extent of the repairs necessary to restore the appearance of the homes. Discussion One point of clarification must be made. A "shroud" is a sheetmetal skirt that is added to the chimney to hide the normal spark arrester. Many of these "shrouds" were made to imitate the appearance of a fully tested and listed.substitute spark ar- rester. There is a difference between a "shroud" that hides an unattractive spark arrester and the.spark'arrester itself. More decorative spark arresters have been available for some time. The requirements for their installation vary from manufacturer to manufacturer. In the case of Pardee Construction, the installa- tions consisted of a fully tested spark arrester hidden behind a "shroud ". The chimneys were made safe by removing the "shroud ". The question now is whether to replace an unattractive spark ar- rester with a more decorative one. 700 FArv._,r'r A­r., O'Arv�rnark (-,lifnrnia Q1091 an5i 5291-6864 In accordance with Council's request, the Building Official spoke with Mr. David Geduld at Pardee Construction on Friday April 5, 1991. He indicated that he would write a letter memorializing our conversation. He also indicated that he in- tends to make himself available to answer Council's questions at this meeting. This memorandum will insure that the information communicated by Mr. Geduld will be passed along in a timely man- ner. Mr. Geduld provides the following information: Models used include :O 1. Tempco Model TFC 2. Tempco Model TFC 3. Marco Model 36CF 4. Heatilator Model 5. Heatilator Model 6. Heatilator Model 39 With Model 200 Glass Doors 39 With Model 175 Glass Doors HD36A ST36A ST 376 Nobody manufactures a "shroud" which has been tested and listed to conceal the spark arrester. These manufacturers do test and list various styles of spark arresters. In order to in- stall a more decorative spark arrester the following work must be done: 1. Remove the existing spark arrester 2. Remove the sheet metal flashing that covers the top of the chimney chase. 3. Modify the chimney with an appropriate chimney adapter kit and chimney sections. 4. Remanufacture or replace the flashing to increase the opening size and rain collar to fit the adapter. 5. Replace the flashing. G. Install a new spark arrester. 7. Paint and repair collateral damage to roof. Staff has spoken with Deford's Fireplace who are in the process of making similar repairs in certain UWC tracts. They indicate that task number four above is required for some manufacturers and is not required for others. They indicate that no remanufacture of the flashing would typically be needed for Tempco fireplaces. They have not had to replace flashings in the UWC tracts. Recommendation Receive and file and provide any further direction to staff.
