PART 8 – WATER PIPING
A. GENERAL PLUMBING CONNECTION GUIDELINES

Pipe material must be suitable to meet local codes and industry standards.

The pipe must be cleaned and without blemish before any connections are made.

Do not apply a torch within 12” of the boiler. Doing so could damage the boiler. Such damages ARE NOT covered by product
warranty.

See Table 16 for minimum CH pipe sizing.

To ease future maintenance isolation valves are recommended on both the CH and DHW loops.

All piping should be insulated.
Use at least the MINIMUM pipe size for connecting the boiler. Failure to follow these guidelines could result in system problems,
increased installation cost, and possible boiler failure.
SUCH COSTS AND FAILURES ARE NOT COVERED BY WARRANTY.
