9 Start-up

Check/control water chemistry

￿CAUTION Do not use petroleum-based cleaning or sealing compounds in the boiler system.

Damage to elastomer seals and gaskets in the system could occur, resulting in substantial property damage.

Hardness less than 7 grains

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

Chlorine concentration less than 200 ppm

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

2.Filling with chlorinated fresh water should be acceptable since drinking water chlorine levels are much lower.

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

Test/replace freeze protection fluid

1.For systems using freeze protection fluids, follow fluid manufacturer’s instructions.

2.Freeze protection fluid must be replaced periodically due to degradation of inhibitors over time. Follow all fluid manufacturer’s instructions.

Freeze protection (when used)

1.Determine freeze protection fluid quantity using system water content, following fluid manufacturer’s instructions. Boiler water content is listed on page 6. Remember to include expansion tank water content.

2.Local codes may require a backflow 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.

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.The minimum cold water fill pressure for a commercial system is 12 psi (82.7 kPa).

b.Pressure will rise when boiler is turned on and system water temperature increases.

Installation & Operation Manual

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

￿WARNING Eliminate all system leaks. Continual fresh makeup water will reduce boiler

life. Minerals can build up in the heat exchanger, reducing heat transfer, overheating the heat exchanger, and causing heat exchanger failure.

Purge air from water system

1.Purge air from system:

2.Open automatic air vent (diaphragm-type or bladder- type expansion tank systems only) one turn.

3.Open other vents:

a.Starting on the lowest floor, open air vents one at a time until water squirts out.

b.Repeat with remaining vents.

4.Refill to correct pressure.
