Enviro 1200, 1700 owner manual Recommended Height for Flue Pipe

Installation

OUTSIDE AIR KIT:

It is mandatory to use outside air for installations in mobile homes.

A 4” (10.2 cm) fresh air adaptor kit is available. This adaptor can be installed either on the back pedestal or through the floor under the pedestal. The cover plate must be installed on the unit if your stove is located in a mobile home or if using outside air from the bottom.

Place the 1⁄4” mesh screen between the fresh air adaptor and the body of the pedestal (as shown to right).

NOTE: Fresh air connection to the unit must be a non-combustible pipe, example: 4” (10.2 cm) single wall aluminum flex pipe.

NOTE: Remove the cover plate on the rear of the pedestal if room air is to be used for combustion air.

RECOMMENDED HEIGHTS FOR FLUE PIPE:

The minimum flue pipe height at sea level is 12 feet (3.7 m) straight up from top of the unit. For every 1000 feet (305 m) above sea level, 4% must be added to the overall height. Use Tables 7, 8, and 9 to calculate the required vertical rise required.
