CSA B140.1 Series:22

Preface 

This is the first edition of the CSA B140.1 Series, Atomizing- and vapourizing-type oil burners. It replaces the following CSA Group Standards: a) CSA B140.1:66, Vapourizing-type oil burners; b) CSA B140.2.1:10, Atomizing-type oil burners; and c) CSA B140.2.2:71, Pressure atomizing oil burner nozzles. The above-mentioned Standards have been amalgamated with the intent to create a single document providing requirements for oil burner construction and performance, as well as requirements for oil burner components. 

This Series contains two Standards: 

- CSA B140.1.1 - Atomizing-type oil burners, which consists of the requirements from CSA B140.2.1 (atomizing-type oil burners) and CSA B140.2.2 (pressure atomizing oil burner nozzles); and 

- CSA B140.1.2 - Vapourizing-type oil burners, which includes the requirements from CSA B140.1 (vapourizing-type oil burners). This Standard should be read in conjunction with CSA B140.0, Oil-burning equipment: General requirements. The major changes from the previous editions of CSA B140.2.1 and CSA B140.2.2, now designated CSA B140.1.1, include the following: 

- throughout the Standard, some rewording has been done for clarity; 

- the scope has been expanded to include the requirements for atomizing nozzles, tubes, and cups (Clause 5.13); 

- new definitions have been added; 

- the requirement for electrical features has been updated to reference CSA C22.2 No. 60335-2-102, which replaces CSA C22.2 No. 3; 

- a new requirement for automatic electrical burner control systems has been added to comply with the requirements of ANSI Z21.20 

- CAN/CSA-C22.2 No. 60730-2-5; 

- tables have been relocated from the end of the Standard to the applicable clause; 

- the Clause 5.13.2 on atomizing nozzles now includes the requirements from CSA B140.2.2, with the following major changes: 

     - the clause title has been changed from "Pressure atomizing oil burner nozzles" to "Atomizing nozzles"; 

     - the notes regarding markings on the nozzles have been deleted; and 

     - SI (metric) units have been added; 

- the following changes have been made to Table 2: 

     - the times for the trial for ignition period and the flame failure response time for appliances with an input rate less than or equal to 11.4 L/h (3.0 US gph) have been divided into two categories: one with an input rate less than or equal to 3.78 L/h (1.0 US gph) and one with an input rate >3.78 L/h (1.0 US gph) and less than or equal to 11.4 L/h (3.0 US gph); 

     - the flame failure response time for some appliances with an input rate between 11.4 L/h (3.0 US gph) and 26.5 L/h (7.0 US gph) has been changed from 3 to 4 s; and 

    - the flame failure response time for appliances with an input rate > 26.5 L/h (7.0 US gph) and less than or equal to 76 L/h (20.0 US gph) has been changed from 3 to 4 s; 

- when testing pumps, the grade of fuel(s) required to be used is now the grade for which the pump is designed or intended. Previously, the lightest-grade fuel with the lowest viscosity was required to be used; 

- the clause on alternate fuel grades for testing has been deleted. Clause 6.8.14 has been added for wetted seals and gaskets exposed to grade B6-B20; 

- the method of test for hydrostatic pressure leakage has been changed; 

- the pressure that components of fuel pumps or units are subjected to during the static pressure leakage test has been changed; 

- the mercurous nitrate immersion test procedure now references UL 125 instead of ASTM B154; 

- the test voltages for ignition have been changed from actual values to a percentage of the nominal voltage. Actual voltage has not changed; 

- the timings for flame failure response time have been provided in Table 2 only; and 

- the marking requirements have been changed to comply with CSA C22.2 No. 60355-2-102 instead of CSA C22.2 No. 3. The major changes from the previous edition of CSA B140.1, now designated CSA B140.1.2, include the following: 

- throughout the Standard, some rewording has been done for clarity; 

- some of the caution statements for labels have been reworded; 

- new definitions have been added; 

- the maximum input rate for vapourizing-type oil burners has been limited to 4.5 L/h (1.2 US gph). Previously, it was unlimited; 

- the requirement for electrical features has been updated to reference CSA C22.2 No. 60335-2-102, which replaces CSA C22.2 No. 3; 

- a new requirement has been added that strainers comply with UL 331; 

- new requirements have been added for constant levelling devices; 

- new requirements have been added for manually lighted burners; 

- a maximum time limit of 5 min has been added for th
