CODES AND STANDARDS
Meets the thermal efficiency and standby loss requirements of the U.S.
Department of Energy and current edition of ASHRAE/IESNA 90.1
Complies with SCAQMD Rule 1146.2 and other air quality management districts with
similar requirements for low NOx emissions. The BTPV 540 and 650 meet the requirements of
SCAQMD 1146.2 of 14 ng/j or 20ppm and other districts having the same requirements. The
BTPV 740 meets code requirements for Texas and other areas of California requiring 30ppm.
