INSTALLATION REQUIREMENTS
The installation must conform to the requirements of the author-
ity having jurisdiction or, in the absence of such requirements,
to the National Fuel Gas Code, Z223.1/NFPA 54 -latest edition.
This installation must also conform to the additional require-
ments in this Slant/Fin instruction book. Installation and service
to be performed by a qualified installer, service agency or the
gas supplier.
NATURAL GAS-FIRED BOILER LOCATION—
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.
Automatic gas ignition system components shall be installed so
these components will not be subjected to dripping, spraying,
rain etc... during operation and service (circulator replacement,
control replacement, etc..)
WARNING
SPECIAL ATTENTION FOR LIQUEFIED PETROLEUM
(L.P.) PROPANE GAS-FIRED BOILER INSTALLATIONS
LPG appliances (boilers) shall be installed in accordance with
applicable provisions of NFPA 58 ( Liquefied Petroleum Gas
Code) latest edition for installations in US and CAN/CGA
B149.1 latest edition for installations in Canada.
Liquefied Petroleum (LP) propane gas is heavier than air there-
fore Propane gas accumulate at floor level. If you suspect a
leak, do not attempt to operate boiler. A spark or flame from the
appliance (boiler) or other sources may ignite the accumulated
propane gas causing an explosion or fire. It is recommended
that inspections for gas leaks be performed periodically by
licensed professional and that leak detection devices be
installed as a further safety measure.
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 boilers,
page 2.
B. For installation on non-combustible floors only.*
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.
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. DO NOT place boilers above floor area containing
radiant tubing.
CHIMNEY REQUIREMENTS—
A. Galaxy II boilers may be vented into a masonry vitreous tile-
lined chimney or UL LISTED Type "B" Venting system NOT
EXPOSED to the OUTDOORS below the roof line.
Venting and sizing of venting system must be in accordance
with National Fuel Gas Code ANSI Z223.1, NFPA 54, -latest
edition which will be referred to as the National Fuel Gas
Code. Local codes apply.
If a masonry chimney is exposed to the outdoors on one or
more sides below the roof line (exterior chimney), ONE of
the following options apply:
1. Chimney must be re-lined with a UL LISTED metallic liner.
When this is done, the chimney will be considered NOT
exposed to the outdoors and the requirements of the
National Fuel Gas Code for NON-exposed chimneys
and/or local codes will apply.
2. If an exposed tile-lined chimney is to be used WITHOUT a
UL LISTED metallic liner, the boiler must first meet the
requirements of the National Fuel Gas Code:
B. If an existing boiler is removed from a common venting sys-
tem, the common venting system may be too large for prop-
er venting of the remaining appliances connected to the
common vent. Follow the test procedure shown in Appendix
"A" on page 25 of this manual to insure proper operation of
venting system and appliances.
C. Inspect for proper and tight construction. Any restrictions or
obstructions must be removed. An existing chimney may
require cleaning.
D. Chimney or vent must extend at least 3 feet above its pas-
sage through a roof and at least 2 feet above any ridge with-
