Install Instructions

10 103448-08- 9/16
WARNING
Explosion Hazard. Asphyxiation Hazard.
Electrical Shock Hazard. Installation of this
boiler should be undertaken only by trained
and skilled personnel from a qualied service
agency. Follow these instructions exactly.
Improper installation, adjustment, service,
or maintenance can cause property damage,
personal injury or loss of life.
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. Multiple
boiler installations greatly reduce the likelihood
of boiler oversizing.
WARNING
Asphyxiation Hazard.
Models with Two-Pipe Vent Connector:
Apply supplied dielectric grease to gasket inside
vent section of two-pipe vent connector. Failure
to apply the grease could result in ue gas leaks
from gasket rupture during vent pipe installation
or gasket deterioration due to condensate
exposure.
A. Installation must conform to the requirements
of the authority having jurisdiction in or, in the absence
of such requirements, 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 CSD1.
B. Boiler is certied for installation on
combustible ooring. Do not install boiler on
carpeting.
C. Provide clearance between boiler jacket and
combustible material in accordance with local re
ordinance. Refer to Figure 2A or 2B for minimum listed
clearances from combustible material. Recommended
service clearance is 24 in. (610 mm) from left side,
III. Pre-Installation and Boiler Mounting
front, top and rear of the boiler. Recommended front
clearance may be reduced to the combustible material
clearance providing:
1. Access to boiler front is provided through a door
or removable front access panel.
2. Access is provided to the condensate trap
located underneath the heat exchanger.
3. Access is provided to thermal link located at
boiler rear.
D. Protect gas ignition system components
from water (dripping, spraying, rain, etc.) during
boiler operation and service (circulator replacement,
condensate trap, control replacement, etc.).
E. Provide combustion and ventilation air in
accordance with section “Air for Combustion and
Ventilation,” of 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
Asphyxiation Hazard. Adequate combustion and
ventilation air must be provided to assure proper
combustion. Install combustion air intake per
Section IV “Venting”.
F. The boiler should be located so as to minimize
the length of the vent system. The combustion air
piping must terminate where outdoor air is available for
combustion and away from areas that may contaminate
combustion air. In particular, avoid areas near chemical
products containing chlorines, chlorouorocarbons,
paint removers, cleaning solvents and detergents.
Avoid areas containing saw dust, loose insulation bers,
dry wall dust etc.
NOTICE
Avoid operating this boiler in an environment
where sawdust, loose insulation bers, dry wall
dust, etc. are present. If boiler is operated under
these conditions, the burner interior and ports
must be cleaned and inspected daily to insure
proper operation.
G. General
1. Alpine boilers are intended for installations
in an area with a oor drain or in a suitable drain
pan to prevent any leaks or relief valve discharge to
cause property damage.
