Locating Boiler
Code Requirements
2. All wiring must comply with
National Electrical
Code
ANSI/NFPA 70.
3. Where required by authority having
jurisdiction, installation must conform to
Standard for Controls and Safety Devices for
Automatically Fired Boilers
, ANSI/ASME CSD-1.
Location Considerations
1. 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 applicable provisions of local
building codes.
2. If replacing an existing boiler, check for and
correct common system problems including:
A. System leaks resulting in premature heat
exchanger failure from oxygen corrosion or
hardness deposits.
B. Inadequate freeze protection resulting in
system freezing and leaking.
C. Dirt or debris left in existing piping if it has not
been properly flushed or cleaned.
3. Appliance is listed for installation on combustible
flooring and must not be installed on carpeting.
4. Install on level floor. For basement installation
provide concrete base if floor is not level or if
water may be encountered on floor around boiler.
5. Protect gas ignition system components from
water (dripping, spraying, etc.) during appliance
operation and service.
6. Locate boiler to avoid water damage in case
there is a leak. If boiler must be located in an
area sensitive to water damage, install drain
pan underneath boiler and pipe to a suitable
drain location. Manufacturer will not be held
responsible for water damage resulting from
this appliance or any of its components.
7. Check for and remove any combustible
materials, gasoline, or other flammable liquids
from area around boiler.
8. Check for and remove any potential combustion
air contaminants from area around boiler. See
Table 4-1.
Clearances
1. Provide clearances between boiler jacket and
combustible material in accordance with
authority having jurisdiction. Minimum
clearances to combustible material shown in
Figure 4-1 and 4-2.
2.
Recommend 24 in. service clearance from left
side, right side and front.
NOTICE:
If recommended service clearances
are not provided, it may be necessary to remove
boiler for service.
3. Boiler must not be installed on carpeting.
1. Installations must conform to requirements of
authority having jurisdiction or, in the
absence of such requirements, to
National Fuel
Gas Code
, ANSI Z223.1/NFPA 54.
