Food Service Technology Center Background The information in this report is based on data generated at the Food Service Technology Center (FSTC). Dedicated to the advancement of the foodservice industry, the FSTC has focused on the development of standard test methods for commercial foodservice equipment since 1987. The primary component of the FSTC is a 10,000 square-foot laboratory equipped with energy monitoring and data acquisition hardware, 60 linear feet of canopy exhaust hoods integrated with utility distribution systems, equipment setup and storage areas, and a state-of-the-art demonstration and training facility. The FSTC Energy Efficiency for Foodservice Program is funded by California utility customers and administered by PG&E under the auspices of the California Public Utilities Commission (CPUC). California customers are not obligated to purchase any additional services offered by the contractor. Policy on the Use of Food Service Technology Center Test Results and Other Related Information Frontier Energy and the FSTC do not endorse particular products or services from any specific manufacturer or service provider. The FSTC is strongly committed to testing foodservice equipment using the best available scientific techniques and instrumentation. The FSTC is neutral as to fuel and energy source. It does not, in any way, encourage or promote the use of any fuel or energy source nor does it endorse any of the equipment tested at the FSTC. FSTC test results are made available to the general public through technical research reports and publications and are protected under U.S. and international copyright laws.

Additions, Deviations, & Exclusions Additions: None Deviations: - Instead of steam generated in the boiler, the NAEB072 boiler and pressure switch were turned off in settings and the unit was tested in the boilerless steam setting. This setting configuration is equivalent to model NAEV072. - Convection heavy load russet potato test data for replicates #2, #3, and #4 listed on page 8 of this report were culled from FSTC report #501311420-R1, Piper NAEB072 Electric Combination Oven, M. Slater, November 2015. Convection mode settings and configuration for the Piper NAEB072 and the Lainox NAEV072 are equivalent. The instrumentation from these 2015 tests is included in the Instrumentation Inventory on page 5. Exclusions: The combination mode ice load cooking uniformity test, as specified in section 10.8 of ASTM F2861-14, was not performed. Page 9 of 15
ENERGY STAR Qualification FSTC testing of the NAEV072 Electric Combination Oven resulted in an idle rate of 1.27 kw in convection mode and 1.13 kw in steam mode and an energy efficiency of 80.7% in convection mode and 70.3% in steam mode. The results comply with the ENERGY STAR Program Requirement for Commercial Ovens,Version 2.2. Page 10 of 15
