1. This boiler is a high efficiency appliance that produces
condensate.
2. The bottom of the boiler has a 3/4 inch pipe for
connection of a 3/4 inch PVC pipe (FIG. 2-2).
3. Slope condensate tubing down and away from the
boiler into a drain or condensate neutralizing filter.
Condensate from the Cadet boiler will be slightly acidic
(typically with a pH from 3 to 5). Install a neutralizing
filter if required by local codes.
A Neutralizer Kit is available from the factory
(KIT3087).
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.
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.
The condensate line
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.
