| | |
| | CODES IN EFFECT: |
| | FBC FG- FLORIDA FUEL GAS CODE SIXTH EDITION 2017 |
| | FBC EX- FLORIDA EXISTING BUILDING CODE SIXTH EDITION |
| | 2017 |
| | FS- FLORIDA STATUTES |
| | FAC- FLORIDA ADMINISTRATIVE CODE |
| | WPB- WEST PALM BEACH AMENDMENTS TO THE FBC SIXTH |
| | EDITION 2017 |
| | |
| | PLAN REVIEW RESULTS: DENIED. |
| | |
| | 1) IN RESPONSE TO THE 3RD REVIEW COMMENTS PRINTED |
| | BELOW, THE DESIGN ENGINEER FOR THE SYSTEM SUBMITTED A |
| | LETTER AND ADDITIONAL EXHAUST DUCT SPECIFICATIONS |
| | THROUGH EMAIL, BUT THOSE DOCUMENTS WERE NOT UPLOADED |
| | INTO THE PROJECT DOX SYSTEM FOR REVIEW. I HAVE ALSO |
| | BEEN ADVISED THROUGH EMAIL THAT MORE DOCUMENTS HAVE YET |
| | TO BE SUBMITTED. PLEASE PROVIDE A COMPLETE SUBMITTAL |
| | PACKAGE FOR THE COFFEE ROASTERS AND COMBUSTION AIR AND |
| | EXHAUST VENTILATION SYSTEMS. THE CURRENT SUBMITTAL |
| | PACKAGE UPLOADED FOR IN THIS REVIEW CYCLE DOES NOT |
| | INCLUDE THE MANUFACTURER'S SPECIFICATIONS FOR THE |
| | PROBAT G90- SECTION 623.1 FBC FG. |
| | |
| | 2) SHEET M.3.2: PROBAT RECOMMENDATIONS PRINTED ON THE |
| | SHEET IDENTIFY THE VENT SYSTEM AS A CHIMNEY. PLEASE SEE |
| | SECTION 202 DEFINITIONS FBC FG- A CHIMNEY IS DEFINED AS |
| | PRIMARILY A VERTICAL STRUCTURE. THE EXHAUST VENT SYSTEM |
| | SHOWN ON THE PLAN IS PRIMARILY A HORIZONTAL STRUCTURE. |
| | AS NOTED IN THE 3RD REVIEW COMMENTS BELOW THE SYSTEM |
| | DESIGN DOES NOT APPEAR TO MEET THE "STRAIGHT OUT" |
| | REQUIREMENT AND IN FACT, IS TRAVELING THROUGH AN AREA |
| | THAT WILL BE OCCUPIED BY B0TH THE PUBLIC AND OTHER |
| | EMPLOYEES. PROBAT RECOMMENDATIONS SPECIFCALLY STATE |
| | THAT WHEN USING A SINGLE WALL DUCT, THE ROASTER AREA |
| | CANNOT BE ACCESSED BY ANYONE OTHER THAN THE OPERATOR. |
| | BASED ON THESE RECOMMENDATIONS IT APPEARS THAT USE OF |
| | THE SINGLE WALL DUCT SYSTEM SHOULD BE ALSO CONFINED TO |
| | THE ROASTER AREA. PLEASE NOTE THE RECOMMENDATIONS DO |
| | NOT HAVE THE SAME LIMITATION OF USE FOR THE DOUBLE WALL |
| | DUCT. |
| | |
| | 3) WITH RESPECT TO THE COMBUSTION AIR/MAKEUP AIR BEING |
| | SUPPLIED MECHANICALLY USING AHU-4, PLEASE ADDRESS THESE |
| | CODE FBC FG REQUIRMENTS: |
| | |
| | A) SECTION 304.9: PROVIDE THE COMBUSTION AIR |
| | CALCULATIONS USING .35 CFMS PER 1000 BTUH TOTAL INPUT |
| | RATING OF THE ROASTERS. |
| | |
| | B) SECTION 304.9.1: EXHAUST FANS ARE SHOWN WHICH |
| | REQUIRE MAKE UP AIR TO REPLACE THE EXHAUSTED AIR. THE |
| | EXHAUST FAN CFM CAPACITIES HAVE NOT BEEN PROVIDED AND |
| | MAKEUP AIR NOT CALCULATED. |
| | |
| | C) SECTION 304.9.2: THE ROASTERS SHALL BE INTERLOCKED |
| | WITH THE SOURCE OF THE AIR TO PREVENT GAS BURNER |
| | OPERATION WHEN THE MECHANICAL AIR SUPPLY SYSTEM IS NOT |
| | IN OPERATION. PLEASE SHOW THE INTERLOCK SYSTEM BETWEEN |
| | THE ROASTERS AND AHU-4. IT IS ALSO IMPORTANT TO REVIEW |
| | THE FBC-MECHANICAL CODE- 2017 IN REGARD TO AIR |
| | BALANCING AND RECIRCULATION RESTRICTION OF AIR FROM THE |
| | ROASTER AREA TO OTHER OCCUPIED AREAS. |
| | |
| | 3RD REVIEW |
| | SHEET M3.2: THERE APPEAR TO BE CONFLICTS BETWEEN THE |
| | PROBAT AND NORDFAB SPECIFICATIONS. THE PROBAT VENTING |
| | RECOMMENDATIONS ON THE NEW PLAN SHEET IDENTIFY THE |
| | ROASTERS AS CLASS III APPLIANCES WITH POSITIVE PRESSURE |
| | VENTING. PLEASE CLARIFY IF CLASS III IS INTENDED TO |
| | MEAN CATEGORY III AS DEFINED IN THE SECTION 202 FBC FG. |
| | |
| | PROBAT RECOMMENDS: |
| | A) POSITIVE PRESSURE VENT SYSTEM. (THE VENT DIAGRAM |
| | DOES INDICATE "POSITIVE PRESSURE" USING EXHAUST FANS AT |
| | THE APPLIANCES). |
| | B) TYPE G DUCTWORK WITH THE TEMPERATURE NOT TO EXCEED |
| | 450 DEGREES F IN THE DUCTWORK. |
| | C) THE SINGLE OR DOUBLE DUCT SHOULD GO "STRAIGHT OUT" |
| | THE WALL. |
| | D) DUCT JOINTS SHALL BE SEALED. |
| | CHECKING DUCT COMPATIBILITY FOR ITEMS A, B, C, & D, THE |
| | NORDFAB SPECS INDICATE: |
| | A) USED UNDER VARIOUS "NEGATIVE STATIC PRESSURES" |
| | B) NOT IDENTIFIED AS TYPE G, AND COMPLETE PROBAT SPECS |
| | HAVE NOT BEEN SUBMITTED SO OPERATING EQUIPMENT AND DUCT |
| | TEMPERATURES ARE NOT KNOWN. |
| | C) THE VENT DIAGRAM INDICATES INDIVIDUAL EXHAUST RISERS |
| | CONNECTING TO A LARGE HORIZONTAL MAIN DUCT WHICH IS |
| | TRAVELING THROUGH OTHER AREAS WHICH DOES NOT APPEAR TO |
| | MEET THE "STRAIGHT OUT" REQUIREMENT. |
| | D) THE DUCT AND JOINTS WILL LEAK WHEN SEALED, AND |
| | LEAKAGE RATES HAVE BEEN ESTABLISHED UNDER "NEGATIVE" |
| | PRESSURES TESTING ONLY. |
| | |
| | BASED ON THE URGENCY EXPRESSED TO ME IN EMAILS FROM THE |
| | OWNER, PROMPT RESPONSES TO THE ABOVE ISSUES WOULD BE |
| | VERY HELPFUL. |
| | |
| | WHEN RESUBMITTING, IT IS HELPFUL TO PROVIDE A RESPONSE |
| | LETTER ADDRESSING EACH ITEM ALONG WITH THE CITY |
| | RE-SUBMITTAL FORM. |
