4. Condensate Neutralizer Container: The condensate
neutralizer container is an additional transparent
container near the front of the boiler. Fill this
container with the condensate neutralizer provided.
The neutralizer will be consumed during normal
operation and should be checked occasionally to
determine if additional neutralizer is necessary.
Neutralizer is available in 1 lb bags (#3354159) from
your RBI Distributor.
5. Bulkhead fitting: The bulkhead fitting allows the
condensate tubing to pass through the jacket without
providing a path for leakage from the jacket. A PVC
TEE is to be attached to the outlet of this fitting to
prevent siphoning of the trap.
6. Neutralizer: Condensate neutralizer is provided in a
package with the boiler to fill the condensate
neutralizer container (Item 4).
7. Neutralizer Cap: This cap provides access for adding
and inspecting the condensate neutralizer.
8. Condensate Drain Tube: This pre-formed tube
connects the condensate system to the bulkhead
fitting for attachment to an external drain.
C. CONDENSATE DRAIN PIPE MATERIAL
The condensate drain is to be piped using PVC,
polypropylene, or other material resistant to acidic
condensate. Do not use steel, brass or galvanized pipe for
this purpose. The acidic condensate will attack most
metals and corrode.
D. CONDENSATE DRAIN PIPE SIZING
The bulkhead fitting for condensate connection is for 3/4"
schedule 40 PVC Pipe. Be sure to use 3/4" or larger
tubing from the boiler to the drain.
CONDENSATE DRAIN PIPING
E. CONDENSATE DRAIN PIPE INSTALLATION
1. Connect a 3/4" schedule 40 PVC Tee to the outlet of
the bulkhead fitting as shown in Figure 6.3. Pipe from
the bottom of the tee to a suitable drain.

2. Be sure that the piping slopes away from the boiler
with a pitch of 1/4" per foot of pipe.
3. If the boiler condensate drain is above the level of a
gravity drain, a condensate pump should be used.
Table 6.1 lists several available brands. Contact your
RBI Distributor for availability.
