Boiler Manual
Prepare condensate trap assembly
This boiler is equipped with an internal air-trap to drain off con-
densate.
1. Remove the condensate trap kit from the accessories bag.
2. See Figures 53, 54 and 55. The figures below shows the installa-
tion of the condensate trap connections.
3. Install the inspection coupling
A
and gasket as shown. Finger
tighten securely.
4. Slide the clamp (from the condensate trap kit) onto the flexible
drain tube (item
B
), See Figure 54. Push the flexible tube (item
B
)
approximately 1-3/4” (Figure 54) onto the end of the tube (bottom
of boiler) as shown in Figure 53.

. The
flexible drain line will 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.
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 dam-
age from condensate spillage. The pump should have a
minimum capacity of 4 GPH for the boiler.
3. When sizing condensate pumps, make sure to include
the total load of all appliances connected to it.
The condensate line must remain unob-
structed, 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, result-
ing 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.
5. Fill the air-trap with approximately 1/2 quart (0.5
liters) of water and connect the condensate drain tube
to the condensate drain system
The condensate trap must be in place during all op-
eration. 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 man-
ual. Failure to comply could result in severe per-
sonal injury, death or substantial property damage.
