The components of the horizontal vent system
must not be penetrated with screws, rivets, or
other devices, either when joining pipes and
fittings or using support straps.  All joints must
be sealed with high temperature silicone before
locking bands are installed.  If the lengths of pipe
must be cut, the joint must still be sealed with
silicone and the locking band used.  When
installing the condensate tube be sure to form
a trap by means of a 3" loop filled with water.
(See Figure 20.)

Keep the number of pipe fittings to a minimum.
Maintain a minimum of 6 inches of air space
between the vent and combustibles at all times,
this includes inside and outside the building.

NOTE:  The direction of the male-female joints
from the drain tee to the termination tee is
opposite to standard gas appliance venting.
The male end of the pipes point towards the
furnace.

Horizontal Venting: *TK Models:

1. By-pass the vent switch, located on blower

compartment door, by removing both wires
from the switch.  Remove wire terminals, strip
wires and tie together in a wire nut.  (See Figure
16.)

2. Remove the rubber tubing from the pressure

switch sensor tube and the collector pan sen-
sor tube.  Cut the tubing approximately 3" from
one end.  Select the appropriate dilution cover
plate as noted with vent kit #903196.  Insert the
bleed tube into the tubing. 

Do not cover the

hole in the bleed tube.  

Place the tubing

assembly back on the pressure switch sensor
tube and collector pan sensor tube. (See Figure
17.)

3. To gain access to the  restrictor plate, remove

and discard the combustion tube from the
transition assembly. 

Insure the seal between

inducer and transition assembly is not
broken. 

(See Figure 18.)

4. Remove and discard the restrictor plate and

screw from the transition assembly. (See Fig-
ure 18.)

5. Install and seal a 4" to 3" reducer to the transition.

(See Figure 19.)  Attach the new high tempera-
ture vent pipe to the reducer.

!  CAUTION:

Do not drill holes through the vent pipe
or fittings on a horizontal vented fur-
nace. Do not use sheet metal screws, or
rivets.  Drilling, screws, or rivets will
cause leaks.
