NOTES:
1. Condensate line must be pitched at least ¼” per foot to properly
drain. If this cannot be done, or a very long length of condensate
hose is used, increase the condensate line to a minimum of 1” ID and
place a tee in the line after the condensate neutralizer to properly
reduce vacuum lock in the drain line.
2. PVC or CPVC pipe should be the only material used for condensate
line. Steel, brass, copper, and other metals will be subject to corrosion
or deterioration.
3. A frozen condensate line could result in a blocked vent condition.
It is very important to protect the condensate line from freezing
temperatures or any type of blockage. In installations that may
encounter sustained freezing conditions, the use of heat tape is
recommended to avoid freezing of the condensate line. It is also
Figure 23 - Condensate Trap Installation
Condensate Neutralization
Condensate from the boiler is slightly acidic with
a pH of 3.2 - 4.5. To avoid long term damage to
the drainage system and to meet local code
requirements, HTP recommends neutralizing the
condensate with a Condensate Neutralizer Kit
(Part # 7450P-212). The neutralizer kit connects
to the drain system and contains limestone chips
that neutralize the pH level of the water vapor.
The neutralizer kit should be checked annually
and the limestone chips replenished if necessary.
When replacing the limestone chips, take care
to ensure chips are no smaller than ½” to avoid
blockage in condensate piping (for piping details,
refer to condensate neutralizer installation
instruction.)
Figure 24 - Condensate Piping Suggestions
recommended to bush up the condensate line size to 1” and terminate
condensate discharge as close to the unit as possible. Longer
condensate runs are more prone to freezing. Damages due to frozen
or blocked condensate lines ARE NOT covered by warranty.
4. Support of the condensate line may be necessary to avoid blockage
of the condensate flow.
5. To allow proper drainage on longer horizontal condensate runs,
tubing size may need to increase to 1” and a second line vent may be
required.
NOTE:
To clean out condensate trap, see Maintenance section.
