Test & Balancing & commisioning for a Comeercial Boiler and water heaters

[John110]

I am designing to replace 2 hot water boiler each 2000 mbh and 3 water heater each 500 mbh. I am looking to find a specification to tell the contractor to follow to test and balance the system and also I am looking for the commissioning requirement and specification.
The owner wants the x manufacturer and This job is for a city facility and I wonder if I say in my specification the approved manufacturer is just X manufacturer and or any manufacturer approved by owner, is it okay or I need to list minimum 3 accepted manufacturer. I appreciate your help.

Package boilers should do, so talk to boiler reps such as Cleaver brooks. There are other US manufacturers but I am more familiar with C.B.. they'll do the installation and do the testing as part of a contract. US manufacturers is my personal choice since overseas manufacturers whose bids may be lower, may give you the cold shoulder should there be a problem.
