CODES AND STANDARDS

All Caravan installations must comply to local codes or, in the

absence of local codes, to the National Fuel Gas Code, ANSI,

Z223.1-latest edition.

In addition where required by the authority having jurisdiction, the

installation must conform to American Society of Mechanical

Engineers Safety Codes for controls and safety devices for

automatically fired boilers, No. CSD-1. The installation must also

conform to the additional requirements of Slant/Fin Instruction Book

publication no. J-40 latest edition.

All electrical wiring is to be done in accordance with the National

Electrical Code ANSI/NFPA No. 70-latest edition and all local electri-

cal codes. The unit must be electrically grounded if an external

power source is used.

In Canada, the installation must be in accordance with standards

CGA B149.1 and B149.2, installation codes for gas burning

appliances and equipment and/or local codes. All electrical

connections are to be made in accordance with Standard C.S.A.

C22.1 Canadian Electrical Code Part 1 and/or local codes.

INTRODUCTION OF FRESH WATER

Introduction of excessive amounts of fresh water into a system can

cause scaling and leave deposits in the boiler and the surrounding

pipes. This will lead to inefficient boiler operation and breakdown.

Fresh water will enter the system as a result of hidden leaks such

as may occur in underground piping. Relief valves should be piped

to a location that shows visible signs of relief.

Process applications that use fresh water, require the use of heat

exchangers. Any process application that results in introduction of

fresh water into a boiler can cause scaling with deposits forming in

the boiler and surrounding piping. This will damage the boiler.

Introduction of fresh water from leaks will cause similar damage.

In some areas it may be necessary to use a feed water treatment to

control the corrosive makeup of the feed water. Check with the local

authority, to determine if the feed water will need a conditioning

treatment before being supplied to the boiler.
