EZ-2

You can't fire an EZ-2 any lower than 1.50 GPH because the burner is designed to fire at over 1.50 GPH or higher. And it doesn't run as well as it could because it is at the bottom of its range. An EZ-1 fires up to 1.65 GPH and will run better at 1.50 GPH or lower.

If you want to convert it to an EZ-1, you need to call Carlin. Website and numbers are above. But you need professional help with this.

You can replace it with an EZ-1 burner but I have found that the 99 FRD is a nicer choice and is more adjustable in range. I just don't know what Carlin Teck Support has to say about it.

There are other things you can do first before getting radical with the burner. Set the high limit control to 170 degrees and see how it heats the house and how the domestic hot water is. Then try 160 degrees. If it gets really cold out, and the house doesn't maintain temperature, turn the high limit back up.
