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.
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 Infinite Energy boiler operates correctly.
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
The PureFire condensate system is designed to prevent
condensate from backing up into the heat exchanger, trap
the condensate to prevent combustion gases from
escaping and neutralize acidic condensate. Refer to Figure
6.1 for an illustration of the system components.
1. Condensate Drain Hoses : The PFW-199, PFW-210
and PFW-399 boilers have two drain hoses attached
to the heat exchanger. The first hose drains
condensate from the combustion chamber of the
boiler. The second hose drains condensate from the
vent system. This prevents dirt and debris from the
venting system from entering the heat exchanger and
fouling the heating surface.
PFW-199, PFW-210 and PFW-399 boilers have only
one drain attached directly to the combustion
chamber. To prevent debris from entering the heat
exchanger, a separate drain can be added to the vent
system as shown in Figure 6.2. However, be sure to
adequately trap any vent system drains.
2. Condensate Collector Container : The condensate
collector container is a transparent container in the
base of the boiler near the back. This container
collects the condensate and acts as a part of a trap to
prevent combustion gases from escaping. The
container is fitted with a level switch that will prevent
the boiler from operating if the condensate line is
clogged.
3. Condensate Float Switch : This switch will prevent the
boiler from operating if the condensate outlet is
clogged before the level of condensate reaches the
heat exchanger.
