Install condensate components
Assemble condensate trap
1. Remove condensate trap parts from the trim bag.
2. See Figure 44 . Slip the fl exible coupling (item 4) over the trap outlet
as shown.
3. Slide the two hose clamps over the fl exible 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 fl exible
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 fl oor and the trap is level.
Connect condensate line
1. Use 1" PVC or CPVC pipe to route condensate to a 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 t-
tings and cement.
2. If installing a condensate pump, select one approved for use with con-
densing boilers and furnaces. Th e pump should have an overfl ow switch
to prevent property damage from condensate spillage. See Figure 46
for required fl ow 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.
Th e 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 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
fi lter if required by local codes. See Replacement parts sec-
tion at the end of this manual for a Weil-McLain condensate
neutralizer kit.
