Install condensate line

Prepare condensate fittings
1. Remove PVC fittings and gasket from the accessories bag.
2. Deburr and chamfer outside and inside of ½" x 1¼" PVC nipple
to ensure even cement distribution when joining.
3. Clean nipple ends and all fittings. Dry thoroughly.
4. For each joint in the condensate line, apply the following. Assemble
parts ONLY in the order given.
a. Apply primer liberally to both joint surfaces — pipe end and
fitting socket.
b. While primer is still damp, lightly apply approved cement to
both surfaces in a uniform coating.
c. Apply a second coat of cement to both surfaces. Avoid using too
much cement on sockets to prevent cement buildup inside.
d. With cement still wet, insert pipe into fitting, twisting ¼ turn.
Make sure pipe is fully inserted.
e. Wipe excess cement from joint. Check joint to be sure a smooth
bead of cement shows around the entire joint.
5. See Figure 68.
6. Assemble the ½" PVC nipple to the PVC reducing elbow as
shown.
7. Allow joint to dry completely. Then slide gasket over nipple as
shown.
8. Slide nipple through jacket condensate line hole to position as
shown in Figure 69, page 50.
9. Cement the ½" tee to the protruding ½" nipple. Be sure both nipple
and reducing elbow finish upright.
Firmly press the reducing elbow and the tee together
while the cement sets to ensure the gasket is securely
compressed. The gasket ensures the jacket enclosure is
airtight at this location.
Connect condensate drain
1. Remove condensate trap line (or line sections) from bag.
2. Slide trap line onto flue outlet condensate connection and
PVC reducing elbow as shown in Figure 71, page 51 and Fig-
ure 72, page 51. (Also see special assembly for Ultra-80 and -105
in step 4. below.)
3. Secure line with hose clamps.
4. Ultra-80 & -105 only — Screw ½-inch hose barb fitting into
½-inch tee and insert into the condensate line sections as shown
in Figure 71, page 51. Slide the ¼-inch hose onto the hose barb
and secure with hose clamp. (The upper end of the hose is factory-
attached to the air inlet trap.)
