Preface:This is the second edition of CSA Standard B140.9.3 (now CAN3-6140.9.3),Portable Kerosine-Fired Heaters, and supersedes the first edition published in 1979.This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:1.1This Standard applies to kerosine-fuelled appliances with capacities up to 4400 W that are primarily used as portable space heating appliances.1.2Appliances with input capacities greater than 4400 W may be examined and tested in accordance with these requirements and with any additional requirements deemed necessary by the regulatory authority.1.3This Standard applies to unvented heaters, in which the products of combustion are discharged into the space being heated.1.4This Standard applies to those heaters in which only Type No. 1-K kerosine is intended to be used as a fuel.1.5This Standard applies to heaters in which fuel is supplied to the burner by a wick under atmospheric pressure conditions, and to heaters in which fuel is fed to the burner under pressurized conditions.1.6This Standard includes requirements for materials, construction, performance, durability, marking, and instructions.
