Slant/Fin SX-150 Manual De Usuario

The installation must conform to the requirements of the authority
having jurisdiction or, in the absence of such requirements, to the
National Fuel Gas Code, ANSI Z223.1-latest edition.

This installation must also conform to the additional requirements
in this Slant/Fin Instruction Book.

NATURAL GAS-FIRED BOILER LOCATION 
Provide a level, solid foundation for the boiler. Location should be
as near as possible to chimney or outside wall so that the flue pipe
from boiler is short and direct.

The location should also be such that the gas ignition system com-
ponents are protected from water (dripping, spraying, rain, etc.)
during appliance operation and service (circulator replacement,
condensate trap, control replacement, etc.).

BOILER FOUNDATION
A. Provide a solid, level foundation, capable of supporting the

weight of the boiler filled with water, and extending at least 2"
past the jacket on all sides. See dimensions of boiler, page 2.

B. For installation on non-combustible floors only.

The

Combustible Floor Kit part number printed on the boiler rating
plate is the only one to be used when installing on combustible
floors. The boiler must not be installed on carpeting.

C. If boiler is to be located over buried conduit containing electric

wires or telephone cables, consult local codes or the National
Board of Fire Underwriters for specific requirements.

er and another appliance are vented to
a single chimney.
