A. Move boiler to approximate installed position.
B. Remove all crate fasteners.
C. Remove outside container with all other inside
protective spacers and bracing. Save two of the
wooden slats from the container sleeve for use in Steps
E and F.
D. Remove four (4) boiler hold-down fasteners. See
Figure 3.
E. Tilt the boiler to one side and slide a wooden slat under
the two nylon glides.
F. Tilt the boiler to the other side and slide another

III. Water Piping and Trim
Figure 3: Removal From Skid
A. Design and install boiler and system piping to
prevent oxygen contamination of boiler water.
Oxygen contamination sources are system leaks
requiring addition of makeup water, fi ttings, and
oxygen permeable materials in distribution system.
Eliminate oxygen contamination by repairing system
leaks, repairing fi ttings, and using nonpermeable
materials in distribution system.
B. Connect system supply and return piping to boiler.
See Figure 4. Also consult I=B=R Installation and
Piping Guides. Maintain a clearance between hot water
piping and combustible construction as required by
local codes. In the absence of local codes, ½" clearance
should be used. Note that a system circulator is
required and is not supplied with the Minuteman II.
F. Provide combustion and ventilation air in accordance
with applicable provisions of local building codes, or
National Fuel Gas Code, ANSI Z223.1, Section 5.3, Air
for Combustion and Ventilation.

This boiler is equipped with a fan which produces an
induced draft through the unit. 100% of combustion air
is pulled in from outdoors and the fl ue gases are
exhausted to the outdoors through the intake air/vent
system. Refer to Section VI.
G. Do not install boiler where gasoline or other fl ammable
vapors or liquids, or sources of hydrocarbons (i.e.
bleaches, cleaners, chemicals, sprays, paint removers,
fabric softeners, etc.) are used or stored.
