SECTION 2

2-10

Corrosion Inhibitor: Capable of maintaining iron corrosion rates <2

mpy. Due to changing environmental restrictions a non-heavy metal
ALL ORGANIC inhibitor is recommended which is designed for multi
metal systems including ferrous metals and yellow metals such as
copper and brass.

Chloride: Less than 250 ppm

Adhere to the following:

1. Refer to your water conditioning or chemical treatment supplier for

analysis and recommendations for proper system conditions.

2. Follow a program with appropriate monitoring and maintenance of

system water conditions as provided by your water conditioning or
chemical treatment supplier.

3. Operate the boiler in a closed-loop system using water or water/glycol

(not requiring a make-up water supply). A large amount of improperly
treated make-up water can cause premature failure of the heat
exchanger resulting from scale build up. Scale build up will reduce the
effi

ciency and useful life of the boiler and is not covered under warranty.

Prevent Oxygen Contamination

There are several ways to prevent boiler water oxygen contamination:

Minimize system leaks to minimize make up water requirement

Do not use open tanks or fi ttings

Do not use oxygen permeable materials anywhere in the water

system

Repair leaks in the system quickly

Eliminate fi ttings wherever possible

Use air elimination devices in system piping

Eliminate System Air

NOTE: There are no built-in boiler air eliminating features.

Adhere to the following for air elimination:

1. The installation of an air separator and air eliminator (air vent) is required.

2. To prevent scale corrosion in boiler and associated piping, make up

water must be kept to a minimum. This is best achieved by ensuring
immediate repair of all leaks and that system pressure is maintained.

3. If a sealed diaphragm-type expansion tank is used, install an air

eliminator in the hot water piping at the air separator.

4. If an air cushion type expansion tank is used, pipe tank directly into

CAUTION

A large amount of improperly treated make-

heat exchanger resulting from scale build
up. Scale build up will reduce the effi
