(a) At the time of issuance of a class A or class B oil-burning equipment installer license, upon payment of the required fee, the commissioner shall issue to the licensee a seal containing the full name of the license holder, the words "licensed oil-burning equipment installer — Class A" or "licensed oil-burning equipment installer — Class B", and the license number. Except as set forth in paragraph (f) below, the license holder shall not be entitled to perform work or hold himself or herself out as a licensed oil-burning equipment installer until such seal has been obtained.
(b) The fee for obtaining a seal shall be one hundred dollars. The triennial renewal fee to retain such seal shall be seventy-five dollars.
(c) If the seal is lost, and an affidavit is submitted by the licensee establishing such fact, a new seal shall be issued by the commissioner upon application and payment of seventy-five dollars.
(d) All documents which are required to be filed with this Department or other government agency in connection with work by such licensee shall bear the stamp of the seal as well as the signature of such licensee.
(e) The seal shall remain the property of the city of New York. Upon revocation of an oil-burning equipment installer's license or death of the licensee or failure of a licensee to renew such license, the seal must be surrendered to the Department.
(f) Persons who hold class A or class B oil-burning equipment installer licenses on the effective date of this rule must obtain their seals within 90 days of the effective date of this rule. Prior to the expiration of this 90 day period, such licensees may perform work under their licenses and hold themselves out as licensed oil-burning equipment installers without the use of a seal.
