A. GENERAL
1. The disposal of all condensate into public sewage
systems is to be in accordance with local codes and
regulations. In the absence of such codes, follow these
instructions.
L’élimination de tout condensat dans les systèmes
d’évacuation publics des eaux usées doit s’effectuer
conformément aux codes et règlements en vigueur.
Si ces codes font défaut, suivre alors ces instructions.
2. Proper piping and removal of condensation from
combustion is critical to the operation of a condensing
appliance. Follow these instructions carefully to assure
that your Series PFC
TM
boiler operates correctly.
Pour le bon fonctionnement d’un appareil à
condensation, l’installation d’une tuyauterie adéquate
et la bonne évacuation de la condensation de la
combustion sont indispensables au fonctionnement
d’un appareil à condensation. Suivre attentivement
ces instructions pour assurer le fonctionnement
optimal de la chaudière Series PFC
TM
.
3. Depending on several factors, the condensate from
gas fired condensing appliances may have a pH value
as low as 2.5 (similar to cola soft drinks). Some local
codes require the use of neutralization equipment to
treat acidic condensate.
B. CONDENSATE SYSTEM
1. The condensate system for Series PFC
TM
boilers
perform the following functions:
a. Prevent condensate from backing up into the heat
exchanger.
b. Trap the condensate to prevent combustion gases
from escaping.
2. Figure 6.1 shows the components of the condensate
system.
a.
Condensate Collector Container
: This vessel is a
transparent plastic container designed to catch the
condensate separately from the heat exchanger
and from the exhaust venting system. This vessel
also acts as part of the trap to prevent combustion
gases from escaping. The container is fitted with a
blocked condensate float switch.
b.
Blocked Condensate Float Switch
: This switch
will cause a blocking error on the boiler control
and prevent the boiler from operating if the level
of condensate in the vessel becomes too high.
High condensate levels can occur as a result of a
blocked condensate drain or similar problem.
c.
Blocked Vent Switch
: A blocked vent switch is
connected to the condensate system to shut the
burner down in case of a vent blockage. The
switch will trip if the pressure in the combustion
chamber exceeds 3.5” w.c. (8.7 mbar) and will
prevent the boiler from continuing to operate with
the condensate trap emptied due to high pressure.
d.
Condensate Drain Tee
: The condensate drain tee,
included in a separate box inside the crate, drains
condensate to the trap and neutralization system
separately from the heat exchanger. This prevents
dirt and debris from the venting system from
entering the heat exchanger.
