INSTALLATION REQUIREMENTS
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 or CSA B149.1-05 for natural gas and propane.
This installation must also conform to the additional
requirements in this Slant/Fin Instruction Book.
BOILER LOCATION
Provide a level, solid foundation or vertical wall for the boiler.
Location should be as near as possible to chimney or out -
side wall so that the flue pipe from boiler is short and direct.
(See paragraph heading "Vent Termination Location and
Clearance" on page 9.) The location should also be such that
all boiler components are protected from water (dripping,
spraying, rain, etc.) during appliance operation and service
(circulator replacement, control replacement, etc.).
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 or CSA B149.1-05 for natural gas and propane.
WARNING
LIQUEFIED PETROLEUM (L.P .) PROPANE GAS-FIRED
BOILER LOCATION
REQUIRES SPECIAL ATTENTION
Liquefied Petroleum (L.P .) propane gas is heavier than air.
Therefore, propane boilers, piping, valves should NOT be
installed in locations where propane leaking from
defective equipment and piping will "pool" in a basement
or other space below the leak.
A spark or flame from the boiler or other source may ignite
the accumulated propane gas causing an explosion or fire.
Provide a level, solid foundation for the boiler. Location
should be as near the chimney as possible so that the flue
pipe from boiler to chimney is short and direct.
The UNIFORM MECHANICAL CODE may be in effect
in your geographic area.
The following precautions are cited by the 1994 UNIFORM
MECHANICAL CODE, section 304.6:
"LPG Appliances. Liquefied petroleum gas-burning
appliances shall not be installed in a pit, basement or
similar location where heavier-than-air-gas might
collect. Appliances so fueled shall not be installed in an
above-grade under-floor space or basement unless
such location is provided with an approved means for
removal of unburned gas."
Consult Chapter 5 of the 1994 UNIFORM MECHANICAL
CODE for design criteria of the "approved" means for
removal of unburned gas.
BOILER FOUNDATION
A. Provide a solid, level foundation or vertical wall capable of
supporting the weight of the boiler filled with water, and
extending at least 51mm (2") past the jacket on all sides.
See dimensions of boilers, page 2. See also figure 4a & 4b
for mounting the boiler on the wall.
B. Boiler can be installed on both combustible and non-
combustible floors, but must NOT be installed on or above
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.

MINIMUM CLEARANCES FROM COMBUSTIBLE
CONSTRUCTIONS
A. Minimum clearances to the exterior surfaces of the boiler
shall be as follows:

B. Provide accessibility clearance of 203mm (8") on sides
requir ing servicing and 457mm (18") on sides used for
passage.
C. All minimum clearances shown above must be met. This
may result in increased values of some minimum
clearances in order to maintain the minimum clearances
of others.
D. Clearance from hot water pipes shall be 25mm (1")**.
** At points where hot water pipes emerge from a floor, wall or ceiling, the
clearance at the opening through the finished floor boards or wall or
ceiling boards may be not less than 1/2 inch. Each such opening shall
be covered with a plate of uncombustible material.
