distance to be maintained.

4.5 Condensate drain connection and trap

The Absolute boiler is fitted with a 1 ¼ NPT drain port near the back and bottom face of the condensate pan. Discharge
the condensate directly into a drain. Only use synthetic material for the connecting pipe-work because of the acidity
of the condensate (pH 2-5) and allow a min. 1.2 inch per 3 ft. [30mm per meter fall], to ensure a good gravity siphon
flow rate. Fill the siphon with clean water before firing the boiler. It is not advisable to discharge into an outside gutter
because of the risk of freezing. If installed outdoors, it must be field heat traced. Consult local codes. A condensate
neutralizer may be required by local code, and should always been used if the drain system is of a cast iron material.
