GAS-FIRED BOILER

Boiler Manual

A. CHECK/CONTROL WATER CHEMISTRY	ically due to degradation of inhibitors over time.
	Follow all fluid manufacturer’s instructions.

WARNING

Do not use petroleum-based cleaning or sealing compounds in boiler system. Damage to elastomer seals and gaskets in system could occur, resulting in substantial property damage.

Water pH between 6.0 and 8.0

1.Maintain boiler water pH between 6.0 and 8.0. Check with litmus paper or have chemically analyzed by water treatment company.

2.If pH differs from above, consult local water treatment company for treatment needed.

Hardness less than 7 grains.

1.Consult local water treatment companies for unusually hard water areas (above 7 grains hardness).

Chlorine concentration less than 200 ppm

1.Filling with chlorinated fresh water should be acceptable since drinking water chlorine levels are typically less than 5 ppm.

2.Do not use the boiler to directly heat swimming pool or spa water.

3.Do not fill boiler or operate with water containing chlorine in excess of 200 ppm.

Clean system to remove sediment

1.You must thoroughly flush the system (without boiler connected) to remove sediment. The high-efficiency heat exchanger can be damaged by buildup or corrosion due to sediment.

2.For zoned systems, flush each zone sepa- rately through a purge valve. (If purge valves and isolation valves are not already installed, install them to properly clean the system.)

3.Flush system until water runs clean and you are sure piping is free of sediment.

Test/replace freeze protection fluid

1.For systems using freeze protection fluids, follow fluid manufacturer’s instructions to verify inhibitor level and that other fluid characteristics are satisfactory.

2.Freeze protection fluid must be replaced period-

B. FREEZE PROTECTION (WHEN USED)

WARNING

NEVER use automotive or standard glycol antifreeze, even ethylene glycol made for hydronic systems. Use only freeze-prevention fluids certified by fluid manufacturer as suitable for use with stainless steel boilers, verified in fluid manufacturer’s literature.

Throroughly clean and flush any system that has has used glycol before installing the new Boiler.

Provide boiler owner with a material safety data sheet (MSDS) on the fluid used.

1.Determine freeze protection fluid quantity using total system water content, following fluid manufacturer’s instructions. Remember to include expansion tank water content.

2.Local codes may require back flow preventer or actual disconnect from city water supply.

3.When using freeze protection fluid with automatic fill, install a water meter to monitor water makeup. Freeze protection fluid may leak before the water begins to leak, causing concentration to drop, reducing the freeze protection level.

C.FILL AND TEST WATER SYSTEM

1.Fill system only after ensuring the water meets the requirements of this manual.

2.Close manual and automatic air vents and boiler drain valve.

3.Fill to correct system pressure. Correct pressure will vary with each application.

a.Typical cold water fill pressure for a residential system is 12 psi.

b.Pressure will rise when boiler is turned on and system water temperature increases. Operating pressure must never exceed 25 psig.

4.At initial fill and during boiler startup and testing, check system thoroughly for any leaks. Repair all leaks before proceeding further.

Gas-Fired Hot Water Boiler specifications

The Munchkin Gas-Fired Hot Water Boiler is a highly efficient heating system that has garnered attention in residential and commercial applications for its innovative design and advanced technology.
