Install condensate line

Prepare condensate trap assembly
1. Remove the condensate trap kit from the accessories bag.
2. See Figure 56 . The left image shows the complete condensate
trap kit.
3. Remove the fl exible drain tube nut, item 2.
4. Push the fl exible tube gasket ring (item 3) onto the end of the
fl exible tube (item 1) as shown in Figure 56 . The tube should
extend through the gasket about ¼ inch.
5. Insert the fl exible tube and gasket into the drain fi tting. When in
position, the offset edge of the gasket ring will rest on the shoulder
of the drain fi tting as shown in Figure 56 , detail 6.
6. Secure the fl exible tube in place by screwing on the nut, item 2.
Finger tighten securely.
Install the condensate trap assembly
1. Remove fl oor stand front access panel (if installed as a fl oor
standing boiler), see Figure 57 .
2. Insert the condensate trap ball, Figure 56 , item 5 into the trap
body (item 4).
The condensate trap ball MUST be in place in the
condensate trap assembly to prevent possible fl ue gas
leakage through the condensate drain system.
3. Loosen the top nut on the trap body.
4. Slide the trap assembly onto the boiler condensate outlet. Firmly
hand tighten the upper nut to secure the condensate trap in place.
5. 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.
6. If fl oor standing boiler, route hose through slot in side of boiler
stand.
Condensate drain system
1.
Install condensate drain by connecting tubing or PVC pipe
to the fl exible drain line. Run the drain tubing or piping to a
fl oor drain or condensate pump
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 certifi ed
PVC or CPVC pipe, fi ttings and cement.
2. Select a condensate pump (if used) that is approved for use with
condensing boilers and furnaces. The pump should have an
overfl ow switch to prevent property damage from condensate
spillage. The pump should have a minimum capacity of 2 GPH for
the EVG 70, 3 GPH for the EVG 110, or 4 GPH for the EVG 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 fl ow 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 fi lter 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.
