shorten the life of these parts. Water conditioning is recommended for water hardness greater than
200 ppm.
DHW output capacity in GPM changes with varying domestic inlet water temperatures.
Do not use ethylene glycol or chemicals that are not explicitly permitted by the boiler installation
instructions. See the “Start-Up and Checkout” section of instructions for important information on
water chemistry requirements.
