Page 5: Notes To Installer
GQ pg. 5 CANADIAN ADDENDUM NOTES TO INSTALLER Gas-fired low-intensity infrared heaters are C.S.A. International design certified for indoor installation only. They are designed and manufactured in compliance with CSA Standard for Gas-Fired Low-Intensity Infrared Heaters, CSA 2.34-2001. The installation must conform with local building codes or, in the absence of local codes, with the current Canadian Natural Gas and Propane Installation Code, CSA B149.1.
