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.
The size of the central heating pipe should be 1” diameter.
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 all boiler loop piping (connecting the boiler to and from the primary / secondary connection).
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.
