Clean/Inspect Trap Assembly
1. Remove the clean out cap on the bottom of the trap. Let
the condensate and any debris drain out.
2. Refill the trap according to the instructions on page 6.

1. This boiler is a high efficiency appliance that produces
condensate.
2. The bottom of the boiler has a 1 1/4 inch pipe for
connection of the condensate trap (FIG. 2-2).
3. Slope condensate tubing down and away from the
boiler into a drain or condensate neutralizing filter.
Condensate from the Knight wall mount boiler will be
slightly acidic (typically with a pH from 3 to 5). Install
a neutralizing filter if required by local codes.

4. Do not expose condensate line to freezing temperatures.
5. Use only plastic tubing or piping as a condensate drain
line (FIG. 2-2).
Use materials approved by the authority
having jurisdiction. In the absence of
other authority, PVC and CPVC pipe
must comply with ASTM D1785 or D2845.
Cement and primer must comply with
ASME D2564 or F493. For Canada use
CSA or ULC certified PVC or CPVC pipe,
fittings, and cement.

6. A condensate removal pump is required if the boiler is
below the drain. When installing a condensate pump,
select one approved for use with condensing boilers
and furnaces. The pump should have an overflow
switch to prevent property damage from condensate
spillage. Call your qualified service technician to inspect
the boiler and system.

NOTICE
To allow for proper drainage on large
horizontal runs, a second line vent may
be required and tubing size may need to
increase to 1 inch.
horizontal runs, a second line vent may
be required and tubing size may need to
increase to 1 inch.
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 manner, condensate can exit
from the boiler tee, resulting in potential
water damage to property. Call your
qualified service technician to inspect
the boiler and system.

Figure 2-2 Condensate Disposal
The condensate trap (FIG. 2-1) must have
the float ball in place during all times of
boiler operation to avoid flue gas emission
from the condensate drain line. Failure to
ensure the float ball is in place could result in
severe personal injury or death.
