Pre-Installation and Boiler Mounting
!
WARNING
Asphyxiation Hazard.
Apply supplied dielectric grease to gasket
inside 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
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
combustible flooring. Do not install boiler on
carpeting.
C. Provide clearance
combustible material in accordance with local
fire ordinance. Refer to Figure 3-3 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:
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.

Installation, Operating, & Service Instructions
(continued)
F. The boiler should be located
to minimize the length of the vent system.
Locate combustion air pipe termination away
from areas that may contaminate combustion
air, (see Table 3-1). 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 ensure proper operation.

in household laundry rooms.
Adhesives used to fasten building products and other similar
products
Excessive dust and dirt
Areas likely to have contaminants:
Dry cleaning/laundry areas and establishments
Swimming pools
Metal fabrication plants
Beauty shops
Refrigeration repair shops
Photo processing plants
Auto body shops
