Condensate Drain Connections
Discharge condensate (acidic water) in accordance with all local codes
and common safety practices.
The micro boiler is a high efciency condensing micro boiler that produces condensate (acidic water).
The acidic condensate generated in the secondary heat exchanger can be neutralized by the Neutral-
izer accessory.
1. Connect a 1/2” FPT X 3/8” (or 1/2”) HB Adaptor 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 Adaptor. The manufacturer
recommends the material of the condensate tube 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 A: If a neutralizer is not required
1. Connect a 1/2” FPT X 3/8” (or 1/2”) HB Adaptor to the condensate drain port at the bottom of the
micro boiler.
2. Connect the Neutralizer to the 3/8” MPT connection of the adapters. 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.
Case B: If a neutralizer is required (installing the Neutralizer assembly)
