Appendix B 7150 Overfill Valve in Tank Shut off Level Worksheet Important: This is meant to be supplemental worksheet and nota substitute to following the installation manual instructions. All length measurements are in inches. Piease contact the Authority Having Jurisdic- ticm (AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off capacity in your region, as well as take into account other considerations such as extreme tank tilt. Take the following measurements with the valve in- stalled in the tank Distance from the 71 SO inlet tube flange to the can lug In the 71 SO body (see figures), upper tube length. Note: the Upper Tube Length must be at least 16" to in- clude the protective bend In the tube. (D)= Distance from the 71 SO inlet tube flange to the top and bottom of lower tube, valve length. (W)= (U) _ Distance from the 7150 inlet tube flange to the bottom of the tank. Note: If a tank bottom protector is present It may be necessary to add this thickness to dimension (OPW 6111 & 61 TP models add 0.6") (8)= From the tank calibration chart provided by tank manu- facturer find the dipstick number M which corresponds to the 100% volume.

If the overfill valve is set above the allowable shut-off percent- age the overfill wive must be removed and replaced. For reference 40 CFR part 280 Subpart B Section 280.20 pwrfill valves should be set to a maximum of 959L Appendix C HOW TO LOCATE THE POSITION OF THE 7150 FOR COMPLETE SHUT-OFF AT A GIVEN TANK CAPACITY Note: This Appendix only applies when AHl require- ments call for complete shut-off at a given tank capacity. See page 4 for standard measurements. The length of the upper tube and the placement of the 7150 valve body determine the shutoff point The sat, ple calculation below will provide for complete shut-off at 95%. In all cases, the upper tube length must be a minimum of 6-1/2' plus the length of the dser pipe. All length measurements are in Inches. INSTRUCTIONS 1. Find the tank capacity(in gallons) from the tank call- bration chart provided by the tank manufacturer. 2. Calculate 95% of capacity. 3. Locate the 95%volume num bar onthe tankcalibra- tion chart. 4. Find the dipstick number (X) which corresponds to the 95% tank volume. And, find the dipstick number (Y) which corresponds to the 100% volume. S. Subtract the dipstick number (X)from the tank diam- eter M to find the upper tube reference number (Z). m-W=(n 6. Add 1.5" to (Z) to find the upper tube depth E (Z)+15'=E 7. Is E less than 6-1/2'7 NO Upper tube length is E plus the distance from the top of the Face Seal Adaptor Installed on the riser pipe to the Inside, top lip of the storage tank (A). Upper Tube Length = E + (A) For testable models only, ending In T: Upper Tube Length - E + (A) -1-1l2" YES Upper tube length is 6.1/2" plus the riser pipe measurement (A). Upper Tube Length = 6.1/2" + (A) For testable models only, ending in "T Upper Tuba R Length = 6-i"+(A) - 1-1/2 NOTE: You must find the actual tank capacity num- ber that correlates to the 6-1/2" + (A) depth for the station records. This number may also be used or the purposes of calibrating an electronic tank level system. EXAMPLE 1. For an Owens-Corning Model G-3 Fiberglass' Tank Calibration Chart: Tank Capacity -10,000 gal. nominal 9,403 gal. NOTE: Use actual capacity only R,xr Rqp seeFaw SalAdaga 2. 95% of actual tank capacity = 0.95 x 9403 gal. _ 8933 gal. 3. The closest number which is less than 8933 gal. Is 8910 gal. Choosing the closest number less than 95% of actual ca patty ensures that complete shutoff will occur when the tank Is no more than 9S% full. 4. The callbration chart reading of 8910 gal. mde- sponds to a dipstick measurement of 82". 5. Dipstick number (X) = 82" Tank diameter M = 92" (Y)-(X)=(Z) (92"-82'=10") (Z) =10" 6. (Z)+15'=E (10"+15'=1151 E = 115" 7. Is 11.5" less than 6.1/2'7 NO Measure the distance from the top of the FSA-400 Face Seal Adaptor installed on the riser pipe to the Inside, top lip of the storage tank and obtain measurement (A). Upper tube length = E+ (A) For testable models only, ending Upper Tube Length = E + IA) - 1-1 /2" 2. To determine lower tube distance from tank bottom to bottom of cut: Subtract valve length (W) from distance to tank bottom (B) W)=(B)-(W)= Note. Lower tube clearance must meet tank manufac- turer requirements and all AHJ, local, state, and national codes. Typical clearance Is about 4". If lower tube clean, ance is not met valve must be removed and adjusted to meet these requirements. 3. To determine lower tube distance from tank bottom to top of cut: Subtract valve length (U) from distance to tank bottom (8) (T) _ (B) - (U) _ Note: Lower tube distance from tank bottom to top of cut must meet all AHJ, local, state, and national codes. For reference per 40 LFR 63 subpart CCCCCC / NESHAP the lower tube can be no more than 6" from the bottom of the tank If lower tube distance is not met valve must be removed and adjusted to meet these requirements. 4. To determine float alignment: Looking Into upper tube (see figure) the float should be aligned along the length of the tank Iffloatisnot aligned properly adjustments need to be made.

All length measurements are in inches. Please contact the Authority Having Jurisdic- tion (AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off capacity in your region, as well as take into account other considerations such as extreme tank tilt. Take the following measurements with the valve in- stalled in the tank: Distance from the 71 SO Inlet tube flange to the cast lug in the 71 SO body (see figures), upper tube length. Note: the Upper Tube Length must beat least 16" to In- clude the protective bend in the tube. (D) _ Distance from the 71 SO Inlet tube flange to the top and bottom of lower tube, valve length. (W)= (U) _ Distance from the 7150 Inlet tube flange to the bottom of the tank Note: If a tank bottom protector is present it may be necessary to add this thickness to dimension (OPW 6111 & 61 TP models add 0.6") (B)= From the tank calibration chart provldad by tank manu- facturer find the dipstick number M which corresponds to the 100% volume.
