HEATER WATER

The piping and components connected to the Munchkin Contender for space the heating application shall be suitable for use with potable water. Toxic chemicals, such a used for boiler treatment, shall not be introduced into the potable water when the Munckin Contender is used for space heating.

When the Munchkin Contender is used to sup- ply potable water, it shall not be connected to any heating system or component(s) previously used with a non-potable water heating appli- ance.

WARNING

NEVER use any toxic chemical, including automotive or standard glycol antifreeze or ethylene glycol made for hydronic (non-potable) systems. These chemicals are poisonous if consumed and can cause injury or death. These chemicals can also attack gaskets and seals in water heaters.

•If you have an old system with cast iron radiators, thoroughly flush the system (without heater connected) to remove sediment. The high-efficiency heat exchanger can be damaged by build-up or corrosion due to sediment.

•Do not use petroleum-based cleaning or sealing compounds in heater system. Gaskets and seals in the system may be damaged. This can result in substantial property damage.

•Do not use “homemade cures” or “boiler patent medicines.” Substantial property damage, damage to heater, and/or serious personal injury may result.

•Continual fresh make-up water will reduce the heater life. Mineral buildup in heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen carried in by make-up water
