Install Condensate Drain Line & Trap Assembly - Weil-McLain Eco Tec 2 Series Manual

ECO ® Tec series 2 gas-fired water boiler – boiler manual
Install condensate drain line & trap assembly
Prepare condensate drain line assembly
1. Remove the condensate trap kit from the bag assembly.
2. Remove the flexile drain nut (Item 2) and tube gasket ring (Item
3) from the trap kit bag assembly.
3. Slide nut (Item 2) onto end of flexible tube (Item 1).
4. Push the flexible tube gasket ring (Item 3) onto the end of the
flexible tube (Item 1) as shown in Figure 66. 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 66, detail 4.
6. Secure the flexible tube in place by screwing on the nut, Item 2.
Finger tighten securely.
Install the condensate trap assembly
1. Remove pedestal front access panel (if installed as a floor standing
boiler), see Figure 67.
2. Slide hose clamp onto condensate outlet tube and hold in place.
3. Slide the trap assembly into the boiler condensate outlet tube.
Tighten the hose clamp to secure the condensate trap in place.
4. If floor standing boiler, route hose through slot in side of boiler
pedestal.
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 Tec 80, 3 GPH for the ECO Tec 110, 4 GPH for
the ECO Tec 150 or 5 GPH for ECO Tec 199.
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 at the
end of this manual for the Weil-McLain kit.
Part number 550-100-270/0122
. The flexible drain line will
The condensate trap, hose clamp, and
condensate drain line must be in place during
all operation. Make sure condensate trap
is securely attached to the condensate tube
outlet and that the condensate drain line
is securely attached to the condensate trap
outlet. Ensure all components are in good
conditioned and installed per this manual.
Failure to comply could result in server
personal injury, death or substantial property
damage.
