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 led
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 certied for installation on combustible
ooring. Boiler must not be installed on carpeting.
D. Provide clearance between boiler jacket and
combustible material in accordance with local re
ordinance. See Figure 3 for minimum listed clearance
to combustible material.
Recommended service clearance is 24 inches (61.0 cm)
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 oor as close to chimney as
possible. For basement installation provide a solid base,
such as concrete, steel or masonry if oor is not level or
if water may be encountered on oor 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 section “Air for Combustion and Ventilation,” of
the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or
Clause 8.2, 8.3, or 8.4 of Natural Gas and Propane
Installation Code, CAN/CSA B149.1, or applicable
provisions of local building codes.
WARNING
Adequate combustion and ventilation air must be
provided to assure proper combustion.
The following guideline is based on the National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
1. General requirements
a. Air for combustion, ventilation and dilution of
ue gases shall be obtained using indoor
combustion air (paragraph 2 below), outdoor
combustion air (3), combination of indoor and
outdoor combustion air (4), engineered
installations (5), or mechanical combustion air
supply (6).
b. Boiler and other appliances shall be located to
prevent interference with proper circulation of
combustion, ventilation and dilution air.
c. Provide make-up air where exhaust fans, clothes
dryers, and kitchen ventilation systems interfere
with operation of boiler and other appliances.
2. Indoor combustion air. Total required volume of
indoor combustion air is the sum of required volume
calculated for all appliances located within space.
Rooms communicating directly with space in which
appliances installed through openings not furnished
with doors, and through combustion air openings
sized and located per paragraph 2c, are considered
part of required volume.
a. Standard method. Minimum required volume is
50 ft
3
per Mbh.
WARNING
If you do not follow these instructions exactly,
a re or explosion may result causing property
damage or personal injury.
DANGER
Do not install boiler where gasoline or other
ammable 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.
