INSTALLATION REQUIREMENTS

IMPORTANT: This equipment must be installed in accordance
with the requirements of CSA B149.1 latest edition for natural
gas and propane. Installation Codes for Gas Burning Appli-
ances must conform to requirements of the local gas compa-
ny, local building codes, and other authorities which have
jurisdiction. Such requirements, where applicable, take prece-
dence over these general instructions. All electrical connec-
tions must be in accordance with Canadian Electrical Code
C22.1 Part 1.
This installation must also conform to the additional require-
ments 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
components 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 51 mm (2") past the jacket on all sides. See dimen-
sions 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.
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 must 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 or CSA B149.1 latest
edition for natural gas and propane:
"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 loca-
tion is provided with an approved means for removal of
unburned gas."
Consult Chapter 5 of the 1994 UNIFORM MECHANICAL
CODE or CSA B149.1 latest edition for propane for design
criteria of the "approved" means for removal of unburned
gas.
