Install condensate line

Prepare condensate trap assembly
1. Remove the condensate trap kit from the accessories bag.
2. See Figure 65. The left image shows the complete condensate
trap kit.
3. Remove the flexible drain tube nut, item 2.
4. Push the flexible tube gasket ring (item 3) onto the end of the
flexible tube (item 1) as shown in Figure 65. The tube should
extend through the gasket about ¼ inch.
5. Insert the flexible tube and gasket into the drain fitting. When in
position, the offset edge of the gasket ring will rest on the shoulder
of the drain fitting as shown in Figure 65, detail 6.
6. Secure the flexible tube in place by screwing on the nut, item 2.
Finger tighten securely.
Install the condensate trap assembly
1. Insert the condensate trap ball, Figure 65, item 5 into the trap
body (item 4).
The condensate trap ball MUST be in place in the
condensate trap assembly to prevent possible flue gas
leakage through the condensate drain system.
2. Loosen the top nut on the trap body.
3. Slide the trap assembly onto the boiler condensate outlet. Firmly
hand tighten the upper nut to secure the condensate trap in place.
4. Place the condensate bracket around the top nut and align the
slot and hole with the holes in the bottom plate. Push the slotted
rivet nuts through the bracket hole and slot into the holes in the
cabinet.
Condensate drain system
1.
Install condensate drain by connecting tubing or PVC pipe
to the flexible drain line. Run the drain tubing or piping to
a floor drain or condensate pump
fit in a ¾" PVC coupling. Run minimum ½" PVC for the piping
to drain or condensate pump.
Use materials approved by the authority having
jurisdiction. In the absence of other authority, PVC and
CPVC pipe must comply with ASTM D1785, F441 or
D2665. Cement and primer must comply with ASTM
D2564 or F493. For Canada, use CSA or ULC certified
PVC or CPVC pipe, fittings and cement.
2. Select a condensate pump (if used) that is approved for use with
condensing boilers and furnaces. The pump should have an
overflow switch to prevent property damage from condensate
spillage. The pump should have a minimum capacity of 2 GPH
for the ECO 70, 3 GPH for the ECO 110, or 4 GPH for the ECO
155.
3. When sizing condensate pumps, make sure to include the total
load of all appliances connected to it.
The condensate line must remain unobstructed,
allowing free flow of condensate. If condensate is
allowed to freeze in the line or if the line is obstructed
in any other manor, condensate can exit from the boiler
tee, resulting in potential water damage to property.
Condensate from the boiler will be slightly acidic
(typically with a pH from 3.2 to 4.5). Install a
neutralizing filter when draining into metal pipe and if
required by local codes. See Replacement parts section
at the end of this manual for the Weil-McLain kit.

The condensate trap and bracket must be
in place during all operation. Make sure the
trap is securely attached to the condensate
outlet and that the condensate discharge line
is in good condition and installed per this
manual. Failure to comply could result in
severe personal injury, death or substantial
property damage.
