PORTABLE LIQUID FUELLED CATALYTIC APPLIANCES

PREFACE This is the first edition of a series of Standards covering minimum requirements for safe operation, acceptable performance, design, construction, manufacture, marking, and testing of portable liquid fuel burning appliances.

In 1966 the CSA Council on Fire Safety asked that consideration be given to preparing standards on portable oil-fired camping appliances. The Subcommittee on Portable Kerosene Heaters was given the task of preparing the Standards on all liquid fuelled portable appliances. Safe and satisfactory operation of portable liquid fuelled appfiances depends to an extent upon proper operation and the proper fuel burned. While these appliances do not require installation and are generally self-contained, the intent and the definitions of the latest issue of CSA Standard B139, Installation Code for Oil Burning Equipment, should be applied to the use of this equipment. This Standard was prepared by the Committee on Oil Burning Appliance Standards under the jurisdiction of the Sectional Committee on Oil Burning Equipment and was formally approved by these Committees.

REXDALE, JUNE, 1972

NOTE: In order to keep abreast of progress in the industries cancerned, CSA Publicalions are subject to periodic review. Suggeslions for improvement will be welcomed at all times. They will be recorded and in due c o w s e brought to the attention of the appropriate Cum m it tee for considera tion. Also, requests for interpretation will be accepted b y the Committee. They should be worded in such a manner as to permit a simple “yes” or “no” answer bused on the literal text of the requiremeitt concerned. All enquiries regarding this Standard should be addressed to Gunadian Standards Association, I78 Rexdale Boulevard, Rsydale 603, Ontario.

REFERENCE PUBLICATIONS A LIST OF PUBLICATIONS REFERRED TO IN THIS STANDARD IS INCLUDED IN CLAUSE 3.1.
