WARNING
-Condensate Drain Connections-
The micro-boiler is a high efciency condensing model that produces condensate (acidic water). The
acidic condensate generated in the secondary heat exchanger can be neutralized by the Neutralizer
accessory.
Case A: If a neutralizer is not required
1. Connect a 1/2" FPT x 3/8" (or 1/2") HB Adapter to the condensate drain port at the bottom of the
micro-boiler.
2. Connect a condensate drain tube to the 1/2" FPT x 3/8" (or 1/2") HB Adapter. The manufacturer
recommends the material of the condensate tube to be either EPDM or PVC.
3. Leave an adequate amount of space between the end of the drain tube and the actual drain, to
facilitate proper drainage.
Case B: If a neutralizer is required (installing the Neutralizer assembly)
1. Connect the 1/2" FPT x 3/8" MPT adapter to the condensate drain port at the bottom of the micro-
boiler.
2. Connect the Neutralizer to the 3/8" MPT connection of the adapter. There is a ow direction
indicator on the neutralizer. Please orient the neutralizer in the proper direction.
3. Connect a 1/2" drain tube to the other end of neutralizer.
4. Leave an adequate amount of space between the end of the drain tube and the actual drain, to
facilitate proper drainage.
