Section B <br /> Ventilation Method <br /> (Choose either balanced or exhaust) <br /> ✓[aalanced,HRV(Heat Recovery Ventilator)or ERV(Energy Caxhaust only(Continuous fan rating in cfm) <br /> Recov-ery Ventilator)—cfm of unit in low must not exceed <br /> continuous venti-lation rating by more than 100%. <br /> Low cfm: 6O and 75 High cfm: 20150 Continuous fan rating in cfm(capacity must not exceed <br /> continuous ventilation rating by more than 100%) <br /> Directions -Choose the method of ventilation, balanced or exhaust only. Balanced ventilation systems are typically HRV or <br /> ERV's. Enter the low and high cfm amounts. Low cfm air flow must be equal to or greater than the required continuous <br /> ventilation rate and less than 100%greater than the continuous rate. (For instance, if the low cfm is 40 cfm, the ventilation <br /> fan must not exceed 80 cfm.)Automatic controls may allow the use of a larger fan that is operated a percentage of each <br /> hour. <br /> Section C <br /> Ventilation Fan <br /> Description Location Continuous Intermittent <br /> Directions - The ventilation fan schedule should describe what the fan is for, the location, cfm, and whether it is used for <br /> continuous or intermittent ventilation. The fan that is chose for continuous ventilation must be equal to or greater than the <br /> low cfm air rating and less than 100%greater than the continuous rate. (For instance, if the low cfm is 40 cfm, the <br /> continuous ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a <br /> percentage of each hour. <br /> Section D <br /> Ventilation Controls <br /> Directions -Describe operation and control of the continuous and intermittent ventilation. There should be adequate detail for plan <br /> reviewers and inspectors to verify design and installation compliance. Related trades also need adequate detail for placement of controls <br /> and proper operation of the building ventilation. If exhaust fans are used for building ventilation, describe the operation and location of any <br /> 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 <br /> with the air handling equipment,please describe such connections as detailed in the manufactures'installation instructions. if the <br /> installation instructions require or recommend the equipment to be interlocked with the air handling equipment for proper operation, such <br /> interconnection shall be made and described. <br /> 2 HRV's Tied to the 2 furnaces with wall controls on main and 2nd floor with high and low settings. <br /> 2 <br />
