INSTALLATION CONSIDERATIONS
1. Determine the best location for the termination kit. Roof
termination is preferred since it is less susceptible to
damage, has reduced intake contaminants and less
visible vent vapors. For side termination, consideration
should be given to:
a. Possible damage from the vapors to plants/shrubs,
other equipment and building materials
b. Possible damage to the terminal from foreign objects
c. Wind effects that may cause recirculation of flue
products, debris or light snow
d. Visible vent vapors.

O NOT OPERATE THE FURNACE WITH THE RAIN CAP REMOVED AS
RECIRUCLATION OF THE FLUE GASES MAY OCCUR.
COLLECT INSIDE THE LARGER COMBUSTIN AIR PIPE AND FLOW TO THE

BURNER ENCLOSURE. AILURE TO FOLLOW THIS WARNING CAN RESULT IN
PROPERTY DAMAGE, EQUIPMENT DAMAGE, PERSONAL INJURY OR DEATH.
Concentric Sidewall Vent Kit (0170K00000S)
This (sidewall only) vent kit is to be used with 2" - 3" vent
systems. The vent kit must terminate outside the structure
and may be installed with the intake and exhaust pipes
located side-by side or with one pipe above the other. This
kit is NOT intended for use with single pipe (non-direct vent)
installations.
Maintain 12" (18" for Canada)
minimum clearance above highest
anticipated snow level. Maximum of
24" above roof.

Condensate Drain Lines and Drain Trap
A condensing gas furnace achieves its high level of efficiency
by extracting almost all of the heat from the products of com-
bustion and cooling them to the point where condensation
takes place. The condensate which is generated must be
piped to an appropriate drain location.
I
N UPRIGHT UPFLOW INSTALLATIONS, THE DRAIN TRAP MUST BE MOUNTED ON
THE OPPOSITE SIDE OF THE UNIT FROM THE JUNCTION BOX.
REDUCE THE RISK OF WATER REACHING THE JUNCTION BOX IN THE EVENT OF
F
A BLOCKED DRAIN CONDITION.
CAN RESULT IN POSSIBLE PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH
DUE TO ELECTRICAL SHOCK.
• If the drain line is routed through an area which may
see temperatures near or below freezing, precau-
tions must be taken to prevent condensate from
freezing within the drain line.
• If an air conditioning coil is installed with the furnace,
a common drain may be used. An open tee must
be installed in the drain line, near the cooling coil, to
relieve positive air pressure from the coil's plenum.
This is necessary to prohibit any interference with
the function of the furnace's drain trap.
Drain Information for Horizontal Installations
NOTE: Horizontal installations require 5.5" under the furnace
to accommodate the drain trap. The horizontal furnace must
be installed with ¾" slope from back to front to permit con-
densate flow towards the front of the furnace.
When installing a *MES9* horizontally with the left side
down, there are two options for connecting the vent pipe to
the furnace.
Option 1
Venting may be connected to the furnace vent pipe fitting on
the original top (now the end) of the furnace.
