Install condensate components
Assemble condensate trap
1. Remove condensate trap parts from the trim bag.
2. See Figure 44. Slip the flexible coupling (item 4) over the trap
outlet as shown.
3. Slide the two hose clamps over the flexible coupling.
4. Tighten one clamp to secure the coupling to the condensate trap.
5. Tighten the other clamp just enough to keep it in place on the flex-
ible coupling until the condensate line has been installed.
Install the condensate trap
1. See Figure 45.
2. Insert the condensate trap inlet gasket (Figure 44, item 6) into the
inlet ferrule (Figure 44, item 2).
3. Slide the condensate trap inlet over the boiler condensate outlet,
located at the lower front center of the boiler.
4. Tighten the ferrule securely by hand.
5. Rotate the condensate trap support leg (Figure 44, item 3) to
extend the support leg down until it touches the floor and the trap
is level.
Connect condensate line
1. Use 1" PVC or CPVC pipe to route condensate to a drain or con-
densate pump.
Use materials approved by the authority having jurisdic-
tion. 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. If installing a condensate pump, select one approved for use with
condensing boilers and furnaces. The pump should have an over-
flow switch to prevent property damage from condensate spillage.
See Figure 46 for required flow capacity. Provide an external power
source for the condensate pump.
3. When sizing condensate pumps, make sure to include the total
load of all SlimFit boilers connected.
The condensate line must remain unobstructed, allow-
ing 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 back up into the boiler, eventually
leading to boiler lockout.
Condensate from the SlimFit boiler will be slightly acidic
(typically with a pH from 3.2 to 4.5). Install a neutralizing
filter if required by local codes. See Replacement parts
section at the end of this manual for a Weil-McLain con-
densate neutralizer kit.
