1. The installation must conform to the requirements of
the authority having jurisdiction 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
2.
Where required by authority having jurisdiction,
installation must conform to the Standard for Controls
and Safety Devices for Automatically fired Boilers,
ANSI/ASME CSD-1.
3.
This boiler series is classified as a Category I. Vent
installation shall be in accordance with “Venting of
Equipment ,” of the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, or “Venting Systems and Air Supply
for Appliances,” of the Natural Gas and Propane
Installation Code, CAN/CSA B149.1, or applicable
provisions of the local building codes.
4. Boiler has met safe lighting and other performance
criteria with gas manifold and control assembly on
boiler per latest revision of ANSI Z21.13/CGA 4.9.
5. Install such that gas ignition system components are
protected from water (dripping, spraying, rain, etc.)
during appliance operation and service, (circulator
replacement, condensate trap, control replacement,
etc.).
6.
Locate boiler on level, solid base as near chimney as
possible and centrally located with respect to heat
distribution system as practical.
7. Verify you have the right size boiler before starting
installation. See rating and capacity table.

Boiler installed in building under construction, take
care to insure clean combustion air supply during
construction process. Airborne particulates such as
from drywall dust and from fiberglass insulation can
clog burner ports and cause incomplete combustion and
sooting.
