CODES AND STANDARDS
Oil-fired Caravan installations must comply to local codes or, in the
absence of local codes, to the ANSI/NFPA 31, Installation of Oil
Burning Equipment, 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. L-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
electrical 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 oil 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.
Use of fresh water will void warranty.
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.
