Preface This is the seventh edition of CSA 8355, lnstollation code for solid-fuel-burning appliances ond equipment. .l It supersedes the previous editions, published in 2001, 1991 ,1987,1984,1982, and 980. Major changes in this edition include revised requirements for the venting of flue gases and for floor and ember protection of appliances. This Code was prepared by the Technical Committee on lnstallation Code for Solid-Fuel-Burning Equipment, under the jurisdiction of the Strategic Steering Committee on Fire Safety and Fuel-Burning Equipment, and has been formally approved by the Technical Committee. April 2010

Use of the singulor does

not exclude the plurol (ond vice verca) when the

sense allows. this Code is stated in its Scope, it is important to note that it remains the responsibility of the users of the Code to judge its suitability for their particular purpose. This publication was developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization os "substantiol agreement. Consensus implies much more than o simple majority but not necessaily unanimity". lt is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full ogreement with qll clauses of this publicotion. CSA Standords are subject to periodic review, and suggestions for their improvement will be reterred to the opproprtak
