I. Pre-Installation
A.
Inspect shipment carefully for any signs of damage. All
equipment is carefully manufactured, inspected and
packed. Our responsibility ceases upon delivery of
boiler to carrier in good condition. Any claim for
damage or shortage in shipment must be filed
immediately against carrier by consignee. No claims for
variances or shortages will be allowed by Boiler
Manufacturer, unless presented within sixty (60) days
after receipt of equipment.
B.
The installation must conform to the requirements of
the authority having jurisdiction. In the absence of such
requirements, installation must conform to the National
Fuel Gas Code , ANSI Z223.1/NFPA 54, and/or Natural
Gas and Propane Installation Code , CAN/CSA B149.1.
Where required by the authority having jurisdiction, the
installation must conform to the
Standard for Controls
and Safety Devices for Automatically Fired Boilers
,
ANSI/ASME No. CSD-1.
C.
Boiler is design certified for installation on combustible
flooring. Boiler must not be installed on carpeting.
D.
Provide clearance between boiler jacket and
combustible material in accordance with local fire
ordinance. See Figure 3 for minimum listed clearance
to combustible material.
Recommended service clearance is 24 (61.0 cm) inches
from left side, right side, and front. Additional clearance
may be required on left side if optional tankless heater
is installed. Service clearances may be reduced to
minimum clearances to combustible materials.
Provide 1/2" (1.3 cm) between combustible
construction and steam/hot water piping.
E.
Install boiler on level floor as close to chimney as
possible. For basement installation provide a solid base,
such as concrete, steel or masonry if floor is not level or
if water may be encountered on floor around boiler.
F.
Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, control
replacement, etc.).
G.
Provide combustion and ventilation air in accordance
with applicable provisions of local building codes, or
with "Air for Combustion and Ventilation" section of
the National Fuel Gas Code , ANSI Z223.1/NFPA 54, or
Sections 8.2, 8.3 or 8.4 of Natural Gas and Propane
Installation Code, CAN/CSA B149.1.
WARNING
Adequate combustion and ventilation air must be
provided to assure proper combustion.
The following guideline is based on the National Fuel
Gas Code , NFPA 54/ANSI Z223.1.
1. Determine volume of space (boiler room). Rooms
communicating directly with space (through
openings not furnished with doors) are considered
part of space.
Volume [ft³] = Length [ft] x Width [ft] x Height [ft]
2. Determine Total Input of all appliances in space.
Round result to nearest 1,000 Btu per hour (Btuh).
3. Determine type of space. Divide Volume by Total
Input.
a. If result is greater than or equal to 50 ft³ per
1,000 Btuh, space is considered an
unconfined
space
.
b. If result is less than 50 ft³ per 1,000 Btuh, space
is considered a confined space .
4. Determine building type. A building of unusually
tight construction has the following characteristics:
a. Walls and ceiling exposed to outside atmosphere
have a continuous water vapor retarder with a
rating of 1 perm or less with openings gasketed
and sealed, and
b. Weather-stripping has been added on openable
windows and doors, and
c. Caulking or sealants applied in joints around
window and door frames, between sole plates
and floors, between wall-ceiling joints, between
wall panels, at plumbing and electrical
penetrations, and at other openings.
WARNING
If you do not follow these instructions exactly,
a fire or explosion may result causing property
damage or personal injury.
DANGER
Do not install boiler where gasoline or other
flammable vapors or liquids, or sources
of hydrocarbons (i.e. bleaches, cleaners,
chemicals, sprays, paint removers, fabric
softeners, etc.) are used or stored.
NOTICE
Due to the low water content of the boiler, mis-
sizing of the boiler with regard to the heating
system load will result in excessive boiler
cycling and accelerated component failure. U.S.
Boiler Company DOES NOT warrant failures
caused by mis-sized boiler applications. DO
NOT oversize the boiler to the system.
