CONDENSATE DRAIN PIPING

6. CONDENSATE DRAIN PIPING
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 Infinite Energy 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 IEW-199 and IEW-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.
IEW-199 and IEW-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.

Installation
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.
