one 90
O elbow (two 45 o elbows equal one 90 o elbow), not including the 45 o elbow attached to the unit.
RESIDENTIAL AND Manufactured Homes / Mobile Homes Installations
The venting arrangements diagrammed below, have a minimum of 75% (flue loss) efficiency with Fan Off, as required for manufactured homes.
(Actual efficiency may be as high as 85%.)
Venting Arrangements Examples:
Example A)
Venting with horizontal termination.
A 10 ft. vertical run with 10 ft. horizontal run falls within the shaded area, and therefore is an allowable installation with Vent Restrictor #2.
Example B)
Venting is not enclosed and has a horizontal termination.
A 7 ft. vertical run with 10 ft. horizontal run falls within the shaded area, and therefore is an allowable installation with no vent restrictor required.
Example C)
Offset to Vertical Vent - Venting with vertical termination.
A 15 ft. vertical run with 4 ft. horizontal offset distance falls within the shaded area and is an allowable installation with Vent Restrictor #1.
INSTALLATION
Note: See page 9 for installation instructions for the Vent Restrictors. These must be installed before the pipe is
connected to the unit. The vent restrictors are shipped inside the stove.
