2.3 Codes & Regulations
The manufacturer assumes no responsibility for
equipment installed in violation of any code or regu-
lation.
Codes and local utility requirements governing the
installation of gas fi red equipment, wiring, plum-
bing, and fl ue connections must be adhered to. In
the absence of local codes, the installation must
conform with the:
a) National Fuel Gas Code ANSI Z223.1 "latest
edition" or CAN/CGA B149 Installation Codes.
The latest code may be obtained from the
American Gas Association Laboratories, 400 N.
Capitol St. NW, Washington D.C. 20001
1-800-699-9277 or www.aga.org
b) Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-1
where required.
c) National Electrical Code NFPA -70.
This boiler is classifi ed Category III according to
ANSI Z21.13 and under the "latest edition" provi-
sions of NFPA54/ANSI Z223.1 and CAN/CGA 149
installation codes. Category III boilers operate
with a positive vent static pressure and with a vent
gas temperature that avoids excessive condensate
in the vent. Installation of the vent system must
be in accordance with the National Fuel Gas Code,
NFPA54/ANSI223.1 or applicable provisions of local
building or fi re codes.
It is recommended that Manual J of the Air Con-
ditioning Contractors Association (ACCA) or A.R.I.
230 be followed in estimating heating requirements.
When estimating heating requirements for installa-
tion at Altitudes above 2000 ft., remember the gas
input must be reduced (See GAS INPUT ADJUST-
MENT).

a) Location Considerations
The location of the boiler is normally selected by
the architect, the builder, or the installer. Howe-
ver, before the boiler is moved into place, be sure
to consider the following requirements:
1. Is the location selected near the chimney or
vent?
2. Do all clearances between the boiler and the
enclosure equal or exceed the minimum stated in
the clearance table?
3. Is there suffi cient space for servicing the boiler
and other equipment? A minimum of 36" front
and top accessibility to the boiler must be pro-
vided. Any access door or panel must permit
removal of the largest component.
4. Are the ventilation and combustion air ope-
nings large enough and will they remain unob-
structed? If outside air is used, are the openings
set above the highest snow accumulation level?
(See page 18 for Combustion and Ventilation
section)
5. The boiler is approved for installation directly
on combustible and non-combustible fl ooring. Do
not install on carpet.
6. Ensure the boiler structure will support the
weight of the boiler.
7. Locate the boiler so that all system components
are protected from water damage during opera-
tion or service.
8. In some applications, boilers may need to be
raised above the fl oor level to reduce the risk of
water damage.
9. In garage applications, refer to ANSI Z223.1 for
guidance.
10. All boilers installed above the level of heat
emitters must have a low water cut-off device
installed. Refer to National, State or Local codes
for guidance.
11. Slowly scaling if only 1/8" in here.
