NOTE
: The maximum achievable steady state efficiency can vary depending the installation and on how the stove is operated.
It is recommended that the pilot flame be turned off if the appliance will not be in use for an extended period of time.
This appliance is equipped for use with the fuel type indicated on the rating plate. Fuel conversion kits that include
the necessary parts and instructions are included with the stove or are available from your installer, dealer or RAIS.
This appliance has been certified by OMNI-Test Laboratories, Inc. to ANSI Z21.88-2005 • CSA 2.33-2005 Vented
Gas Fireplace Heaters and CAN1-2.17-M91, Gas-Fired Appliances for Use At High Altitudes.
The GABO is approved for installation at elevations up to 2000 feet in the U.S. and 1370 meters (4500 feet) in Can-
ada without change. If your installation is at an elevation greater than these, consult with the local authority having
jurisdiction for gas product installations to determine their specific requirements for high altitude installations.
