Pinnacle Boiler Piping

Rob_15

I have a customer who is installing a Pinnacle boiler.He piped it exactly the way the book shows and the secondary loops are not getting hot.He put in a Taco 0011 for the primary and Taco 007ifc for secondarys.

Sounds like...

your cuistomer may have reversed the P/S pump models?

The primary loop is typically the larger diameter pipen and the shortest as well. Therefore, resistance to flow would require more head than the relatively (typically) longer and smaller diameter secondary loop?

A heat gun pointed at these four points would be most helpful: The boiler outlet temp; the boiler return temp, each of the secondary supplies; and, the secondary returns.

Just remember, the emissivity of copper tube requires a 1" square of flat black spray paint to correct fasle temp readings from "guns" used on shiny surfaces.

I suspect something simple:

1. Air bound somewhere.

2. S & R of secondary loop(s) installed "backwards."

3. Conflict of flows negating secondary load flow.

Since the boiler was piped exactly as shown in the manual (your statement), something NOT in the manual is wrong?
