We have two items we would like to go over with you that we feel are very important.
Solenoid Adjustments
Solenoids are only designed to lift 3⁄4”. There are only two rivets on the shaft of the solenoids. When the solenoid and damper plate is in the OFF position, you should only see one and a half rivets, shown in the left image. The image on the right shows incorrect installation.
Return Boiler Water Temperature
Your return boiler water temperature should be no less than 145°. For example: if you are running your boiler at 160° and your home has a 20° Delta T and your underground line loss is 2°, your return boiler water temperature is 138°. Any water temperature below 145° will create condensation and cause premature corrosion boiler failure over time.
If you have any questions regarding these topics, call our head office, we are ready to help you.
