2. Remove the rubber tubing from the pressure switch
sensor tube and the collector pan sensor 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 16.)
3. To gain access to the restrictor plate, remove and
discard the combustion tube from the transition assem-
bly.
Insure the seal between inducer and transition
assembly is not broken.
(See Figure 17.)
4. Remove and discard the restrictor plate and screw from
the transition assembly. (See Figure 17.)
5. Install and seal a 4" to 3" reducer to the transition. (See
Figure 18.) Attach the new high temperature vent pipe
to the reducer.
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 15.)
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.
1.
Apply an adhesive bead around the outside of the
pipe approximately 1/4" from the end of the pipe.
This includes the first fitting or pipe attached to the
furnace.
2.
Push the pipe and fitting together while twisting the
pipe or fitting. Twisting the pipe or fitting spreads the
adhesive completely within the fitting socket.
3.
When the pipe is at the socket bottom, inspect the
joint. Look for a complete, uninterrupted ring of
adhesive material around the pipe at the fitting
socket. Additional adhesive or rotation of the pipe or
fitting may be required for a complete seal. The
