Challenger User Manual

ppliance & System Water

• Have the appliance and system water chemistry

hecked at least annually by a qualified service tech-

nician.

• Do not use petroleum-based cleaning or sealing

compounds in the appliance or system. Gaskets

and seals in the system may be damaged. This can

result in substantial property damage.

• Do not use any product not specifically designed for

hydronic heating systems. Serious damage to the

appliance, piping system, personnel and / or proper-

ty may result.

• Continual fresh makeup water will reduce the life of

the CHALLENGER. Addition of oxygen can cause

internal corrosion in the system components. All

leaks in the piping system must be repaired at once

to prevent makeup water.

• Do not add cold water to a hot appliance. Thermal

shock can cause premature failure to the appliance

heat exchanger.
