INSTALLATION
PLANNING YOUR VENTING INSTALLATION
See page lOfor Exterior VentTermlnatlon
requirements. The U27 is only approved for
a horizontal termination. See the diagram for
minimum and maximum pipe lengths.
When planning your installation, it will be
necessary to select the proper length of vent
pipe for your particular requirements. Deter¬
mine the minimum clearance to combusti¬
bles from the rear of the unit to the wall. It is
also important to note the wall thickness.
Before cutting the vent hole through the wall
ensure that ALL vent and termination clear¬
ances (see page 10) will be met.
The venting arrangements shown on the
diagram, have a minimum of 75% (flue loss)
efficiency with Fan Off, as required for man¬
ufactured homes. (Actual efficiency may he
as high as 85%.)
*lf this is an outside corner, the minimum distance between the vent and
tile outside comer is 12" (30cm). See "F" on the diagram on page 10.
Max. 17-1/4"
NOTE: Ensure compliance with the outside vent terminal location before
cutting hole as both dimensions must be met.
