Installling indirect water heater
I am planning on a DIY install of a Crown MS-40 indirect water heater. I currently use the DHW coil in a Crown 120,000 BTU/hr boiler.
I have the MS-40 on site. I still need to get T/P valve rated at 181,800 or higher, 2 of the Taco Z075C2, 3/4" Sweat Motorized Zone Sentry Zone Valves and to make the MS-40 priority and supply 24VAC for the zone valves I need a Honeywell R8285A Control.
I have been through the install manual and think I meet all the requirements. I only have a few questions:
1. Anything special when teeing off the supply and return 3/4 copper to add the new zone?
2. The Honeywell aqua-stat L7224A currently has a low limit of 180 with the differential of 16 and no other DHW settings turned on. What should I consider for the settings after the MS-40 is connected?
