WARNING
Explosion Hazard. Asphyxiation Hazard.
Electrical Shock Hazard. Installation of this
boiler should be undertaken only by trained
and skilled personnel from a qualified 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.
Crown 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.
Apply supplied dielectric grease to gasket inside
vent section of two-pipe vent connector. Failure
to apply the grease could result in flue 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 CSD-1.
B. Boiler is certified
for installation on combustible
flooring. Do not install boiler on carpeting.
C. Provide clearance
between boiler jacket and
combustible material in accordance with local fire
ordinance. Refer to Figure 2 for minimum listed
clearances from combustible material. Recommended
service clearance is 24 in. (610 mm) from left side,
front, top and rear of the boiler. Recommended front
clearance may be reduced to the combustible material
clearance providing:
III. Pre-Installation and Boiler Mounting
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 applicable provisions of local building
codes, or: USA - National Fuel Gas Code , ANSI
Z223.1/NFPA 54, Air for Combustion and Ventilation;
Canada - Natural Gas and Propane Installation Code ,
CAN/CSA-B149.1, Venting Systems and Air Supply for
Appliances.
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, chlorofluorocarbons,
paint removers, cleaning solvents and detergents.
Avoid areas containing saw dust, loose insulation fibers,
dry wall dust etc.
NOTICE
Avoid operating this boiler in an environment
where sawdust, loose insulation fibers, 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. Phantom boilers are intended for installations in an
area with a floor drain, or in a suitable drain pan to
prevent any leaks or safety relief valve discharge
resulting in property damage.
2. Phantom boilers are not intended to support external
piping and venting. All external piping and venting
must be supported independently of the boiler.
3. Phantom boilers must be installed level to prevent
condensate from backing up inside the boiler.
