Alpine Installation, Operating, and Service Instructions

12 103448-02 - 6/13
WARNING
If you do not follow these instructions exactly,
a re or explosion may result causing property
damage or personal injury.
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.
A. 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, NFPA 54/ANSI Z223.1, and/or CAN/
CSA B149.1 Natural Gas and Propane Installation
Code.
B. Boiler is design 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 Figures 2A and 2B for minimum
listed clearances from combustible material.
Recommended service clearance is 24 inches from left
side, 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.
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 applicable provisions of local building codes,
or: USA - National Fuel Gas Code, NFPA 54/ANSI
Z223.1, Air for Combustion and Ventilation;
Canada - Natural Gas and Propane Installation Code,
CAN/CSA-B149.1, Venting Systems and Air Supply for
Appliances.
III. Pre-Installation and Boiler Mounting
WARNING
Adequate combustion and ventilation air must
be provided to assure proper combustion.
F. The boiler should be located so as to minimize the
length of the vent system. The combustion air piping,
or the optional concentric vent piping, containing
integral combustion air inlet 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.
CAUTION
Avoid operating this boiler in an environment
where saw dust, 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
2. Alpine boilers are not intended to support external
piping and venting. All external piping and venting
must be supported independently of the boiler.
3. Alpine boilers must be installed level to prevent
condensate from backing up inside the boiler.
4. Alpine boilers can be installed either as oor
standing (ALP080B thru ALP399, or, as wall hung
(ALP080B thru ALP210B). Factory assembled
oor standing models are identied with sufx F in
a boiler part number code (example – ALP210BF-
1L02). Factory assembled wall hung models are
identied with sufx W in a boiler part number code
(example – ALP210BW-1L02).
5. Boiler Floor Standing Installation:
a. For basement installation provide a solid base
such as concrete, where oor is not level or water
may be encountered on the oor around boiler.
Floor must be able to support weight of boiler,
water and all additional system components.
b. Boiler must be level to prevent condensate from
backing up inside the boiler.
