Cover Letter: A letter addressed to the chief of the ECARS Division. This letter must request an Approval Letter for the fuel-fired heater and include a statement of compliance in regards to the idling requirements set forth in 13 CCR 1956.8(a)(6)(D) and 13 CCR 2485(c)(3)(B), and the LEV II ULEV emissions standards in 13 CCR 1961(a)(1).

Testing information and results – date, location, tested heater identification, emissions results
List of heater models – make, model, etc. and heating capacity .
Labeling Information: Manufacturers of fuel-fired heaters are not required to affix emissions labels to their products; however, if a manufacturer voluntarily elects to identify a heater as approved by the California Air Resources Board (CARB), then it is requested that label schematics or photos be submitted for review to ensure that inaccurate claims are not made. In particular, equipment for which Approval Letters are issued must be described as “Approved” rather than “Certified”.
