WARNING

Grand Canyon Gas Logs burner system is to be installed only in a solid-fuel-burning fireplace with a working flue 

constructed of noncombustible material. Solid fuels shall not be burned in a fireplace where the unit is installed. 

The installation, including provisions for combustion, ventilation air, and required minimum permanent vent  

opening, must conform with the National Fuel Gas Code (ANSI Z223.1/NFPA 54)\ and applicable local building 

codes. In Canada, the installation must conform with the Natural Gas and Propane Storage and Handling 

Installation Code (CSA-B-149.1). A damper stop clamp is included to maintain the minimum permanent vent 

opening and to prevent full closure of the damper blade. The chimney damper must be fixed fully opened 

when burning the unit. The burner system is designed to burn with yellow flames; thus, adequate 

ventilation is absolutely necessary. If any of these parameters are not met, the warranty could be voided.
