Munchkin Water Temperature

[xlzpdr]

I have a new Munchkin 80M boiler with Superstor. I feel the water temperature at 180* is too high. How do I lower it. I have been using more gas with the Munchkin than I did with my ancient Repco boiler. Apparently Munchkin does not produce an owner's manual. Can someone guide me to lower the water temperature to 160*?

Munchkin has a manual for your unit on line at there web site. Careful with those adjustments they can be touchy.

Thanks HVAC! You used the magic word that they can be "touchy." Changing water temperature was a breeze with my old boiler. This sounds a bit over my head.

By the way, my install has everything, cirulatorm expansion tanl, zone valves etc, above the boiler. What happens to the boiler should a leak occur?

The boiler will be shut down by a low water pressure switch. Keep your automatic fill water feed valve opened at all times and have the pressure set acording to your system needs.
