Preface This is the second edition of CSA B140.10, Oil-fired warm-air heating appliances for mobile housing and recreational vehicles. It supersedes the previous edition published in 1974. It is one of a series of oil-burning equipment Standards covering minimum requirements for the safe operation, acceptable performance, design, construction, manufacture, marking, and testing of oil-burning equipment and should be read in conjunction with CSA B140.0, Oil-Burning Equipment: General Requirements. Changes to this new edition include the following: (a) The referenced Standards and definitions have been updated. (b) The Scope of the Standard has been clarified. (c) References to external “flues” and “flue pipes” have been changed to “vents” and “vent pipes”. (d) Filter specifications have been updated. (e) Requirements for the installation, service, and operating instructions have been updated and now indicate some homeowner instructions. Some marking requirements have been modified. (f) Maximum vent outlet temperature requirements have been updated. (g) All numeric values have been converted to SI (metric) units, with yard/pound (imperial) or US Customary units shown for information only. This Standard was prepared by the Technical Committee on Oil-Burning Appliance Standards, under the jurisdiction of the Strategic Steering Committee on Fire Safety and Fuel Burning Equipment, and has been formally approved by the Technical Committee. It will be submitted to the Standards Council of Canada for approval as a National Standard of Canada. March 2006 Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows. (2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. (3) This publication was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication. (4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. (5) All enquiries regarding this Standard, including requests for interpretation, should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation should (a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch; (b) provide an explanation of circumstances surrounding the actual field condition; and (c) be phrased where possible to permit a specific “yes” or “no” answer. Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSA’s periodical Info Update, which is available on the CSA Web site at www.csa.ca.

Oil-fired warm-air heating appliances for mobile housing and recreational vehicles

Foreword The Canadian Standards Association (CSA) develops standards under the name Canadian Standards Association, and provides certification and testing under the name CSA International. CSA International provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represent its professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be deemed to meet the Standard providing the feature or difference is found acceptable utilizing appropriate CSA International Operating Procedures. Products that comply with this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this Standard. Products shall not be certifiable if they are discovered to contravene applicable laws or regulations. Testing techniques, test procedures, and instrumentation frequently must be prescribed by CSA International in addition to the technical requirements contained in Standards of CSA. In addition to markings specified in the Standard, CSA International may require special cautions, markings, and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility, or personnel for or in connection with the test is furnished by the manufacturer or the Association. Manufacturers should note that, in the event of the failure of CSA International to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should submit the matter, in writing, to the Secretary of the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notices, and Technical Information Letters that may be applicable and for which there may be a nominal charge. For such information or for further information concerning CSA Certification, please address your inquiry to Applications and Customer Service, CSA International, 178 Rexdale Boulevard, Toronto, Ontario, Canada M9W 1R3.

Annex A (informative) Calculation of air-free sample Note: This Annex is not a mandatory part of this Standard.

Calculations for air-free correction of the carbon monoxide test (see Clause 7.2.2.7) may be computed using either the oxygen or carbon dioxide method below: (a) Carbon dioxide method: Corrected % of CO = %CO × CO2U/CO2T where %CO = CO reading taken during the test CO2U = ultimate CO2 for fuel used CO2T = CO2 reading taken during the test

Note: Instead of %CO the result may be taken in ppm (parts per million) with no effect on the result.

(b) Oxygen method: Corrected % of CO = %CO × O2B/O2T where %CO = CO reading taken during the test O2B = maximum oxygen per cent at the air intake to the burner (normally 20.8%) O2T = O2 reading taken during the test

Note: Instead of %CO the result may also be taken in ppm (parts per million) with no effect on the result.
