Horizontal Right Air Flow (Inducer High)
Refer to Figures 33-36
Installation with condensate trap bracket (Front of casing):
Refer to Figure 33 & 34
1.
Remove the 2" knockout on the casing side, away from the
inducer motor.
2.
Remove all the condensate hoses inside the furnace, including the
3/8" barbed nipple, factory installed, in the rain gutter.
3.
Remove the drain cap from the bottom rain gutter drain and insert
the 3/8” barbed nipple removed above in the bottom rain gutter
drain. Place the cap, just removed, to the other side of the rain gut-
ter on the inducer.
4.
Remove the condensate trap and its bracket from inside the fur-
nace, saving the screws for later use.
5.
Remove the large condensate cap from the side of the condensate
pan and install it on the middle drain of the condensate pan, from
where #1 hose was removed.
6.
Install longer dogleg end of hose #10 through the casing hole on to
the side drain of the condensate pan, where cap was removed in
step #3. Some lubricant may have to be used to facilitate this
installation as the hose is designed to be a tight fit over the con-
densate drain. The other, smaller, dogleg end of hose #10 should
be installed into the large recessed drain in the condensate trap.
7.
Install the condensate trap bracket, with the condensate trap, on to
the front side of the furnace, using the screws removed in step #1.
8.
Install the dogleg end of hose #9 on the Wye drain and route the
hose through the opening on top of the furnace, as shown. Install
the other end of the #9 hose to the barbed tee, inside the furnace.
9.
Install the dogleg end of hose #4 to the rain gutter on the inducer.
The other end of hose #4 should be installed on the 3/8" barbed
tee.
10. Install one end of hose #7 on the 3/8" barbed tee inside the fur-
nace. Guide the other end of hose #7 towards the condensate
trap, and install it on the tap on the condensate trap.
11.
Install the dogleg end of hose #2 on the bottom drain of the
inducer. Guide the other end of hose #2 towards the condensate
trap, and install it on the small recessed drain in the condensate
trap.
12. Ensure that all hoses are properly installed, have no kinks, and are
draining properly. All hoses on the condensate trap and conden-
sate pan should be pushed all the way down to ensure against
leakage and performance. Some hoses may have to be trimmed
for proper fit.
NOTE:
The condensate trap can also be installed on the 2" knockout
opening, in this configuration, using the provided condensate trap
bracket. Some modifications may, however, have to be made to the
condensate hoses.
Installation with condensate trap bracket (Back of casing):
Refer to Figure 35 & 36
1.
Remove the 2" knockout on the casing side, away from the
inducer motor.
2.
Remove all the condensate hoses inside the furnace, including the
3/8" barbed nipple, factory installed, in the rain gutter.
3.
Remove the drain cap from the bottom rain gutter drain and insert
the 3/8” barbed nipple removed above in the bottom rain gutter
drain. Place the cap, just removed, to the other side of the rain gut-
ter on the inducer.
4.
Remove the condensate trap and it's bracket from inside the fur-
nace, saving the screws for later, use.
5.
Remove the large condensate cap from the side of the condensate
pan and install it on the middle drain of the condensate pan, from
where #1 hose was removed.
6.
Do not remove condensate trap from the condensate trap bracket.
7.
Cut 2-1/2" straight piece from hose #1 and install it through the
knockout opening in the casing on the side of the condensate pan,
from where the cap was previously removed. Insert the other end
of the hose into the large recessed drain on the condensate trap.
8.
Install the condensate trap bracket to the 2” inch hole on the side
of casing, using existing holes, lining up the condensate pan open-
ing with the larger opening on the condensate trap.
9.
Install the dogleg end of hose #9 on the Wye drain and route the
hose through the opening on top of the furnace. Install the other
end of the #9 hose to the barbed tee, inside the furnace.
10. Install the dogleg end of hose #4 on 3/8" barbed nipple, in the rain
gutter. The other end of hose #4 should be installed on the 3/8"
barbed tee.
11.
Install one end of hose #7 on the 3/8" barbed tee inside the fur-
nace. Guide the other end of hose #7 towards the condensate
trap, and install it on the tap on the condensate trap
12. Install the dogleg end of hose #2 on the bottom drain of the
inducer. Guide the other end of hose #2 towards the condensate
trap, and install it on the small recessed drain in the condensate
trap.
13. Ensure that all hoses are properly installed, have no kinks, and are
draining properly. All hoses on the condensate trap should be
pushed all the way down to ensure against leakage. All hoses on
the condensate pan should be pulled all the way up to ensure
proper operation.
Ensure all condensate hoses are pushed all the way down on the
condensate trap, barbed fittings, and condensate pan drains.
Plug all unused condensate trap, condensate pan and inducer drain
connection points using plugs provided.
