Operating instructions
GALAXY GG SERIES
GALAXY 3
INSTALLATION REQUIREMENTS
The installation must conform to the requirements of the
authority having jurisdiction or, in the absence of such require-
ments, to the National Fuel Gas Code, ANSI Z223.1-latest edi-
tion or CSA B149.1-00 for natural gas and propane.
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 water
during installation or service.
WARNING
LIQUEFIED PETROLEUM (L.P.) PROPANE GAS-FIRED
BOILER LOCATION
REQUIRES SPECIAL ATTENTION
Liquefied Petroleum (LP) 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 B149.1-00 for
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
location is provided with an approved means for removal
of unburned gas."
Consult Chapter 5 of the 1994 UNIFORM MECHANICAL
CODE or CSA B149.1-00 for design criteria of the
"approved" means for removal of unburned gas.
CHIMNEY REQUIREMENTS—
A. Galaxy boilers may be vented into a masonry vitreous tile-
lined chimney or Type “B” Venting system NOT EXPOSED to
the OUTDOORS below the roof line.
Venting and sizing of venting system must be in accordance
with the requirements of the local gas utility, local building
codes and other authorities having jurisdiction.
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 an approved 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
metallic liner, the boiler must first meet the requirements of
the following tables and paragraphs of the National Fuel
Gas Code:
I. For Single Galaxy Boiler—Paragraph 11.2.9 and table
11.11.
II. For multiple appliances—Paragraph 11.3.18 and table
11.12 (or 11.13 if applicable).
In addition, all requirements of the local gas utility, local
building codes and other authorities having jurisdiction
apply.
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 20 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 914 mm (3 feet) above
its passage through a roof and at least 914 mm (3 feet)
above any ridge within 3048 mm (10 feet) of the chimney.
MINIMUM CLEARANCES FROM COMBUSTIBLE
CONSTRUCTION —
A. Minimum boiler clearances shall be as follows:
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 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.
