INSTALLATION OF HEATER AND FLUE PIPE IMPORTANT: Check and comply with all state and local codes that may apply to vented heaters before beginning installation. NOTE: This heater is designed to be used at altitudes up to 1000 m above sea level. For use at altitudes higher than 1000 m and up to 2000 m adjustments to the heater must be made. - Page 20 For standard installation, use the template enclosed with the heater to position the hole for the flue pipe. Tack or tape template to the wall at the desired position (See Fig. 4). Tape Fig. 4 NOTE: Heater should be installed on a sturdy floor that is level and flat. NOTE: The template can be adjusted for use of non-standard installations such as the use of extension pipe kits.
