Operating instructions

BEFORE YOU START
Check to be sure you have the right size boiler before
starting the installation. See rating and capacity table on
previous page. Also be sure the new boiler is for the type of
gas you are using. Check the rating plate on the right side of
the boiler.
You must see that the boiler is supplied with the correct type
of gas, fresh air for combustion, and a suitable electrical
supply. Also, the boiler must be connected to a suitable
venting system and an adequate piping system. Finally, a
thermostat, properly located, is needed for control of the
heating system. If you have any doubts as to the various
requirements, check with local authorities and obtain
professional help where needed. Take the time to complete
all of the steps for SAFE and PROPER operation of the heating
system.
If this boiler is installed in a building under construction,
special care must be taken to insure a clean combustion air
supply during the construction process. Airborne particulates
such as from drywall dust and from fi berglass insulation can
clog the burner ports and cause incomplete combustion and
sooting.
These boilers are designed for use in closed heating systems
where all of the steam is returned to the boiler as condensate
and the amount of make-up water required is minimal.
These boilers are not designed for or intended for use in
open systems of process applications using 100% make-up
water. Damage to the boiler resulting from such use shall
not be covered under the warranty.
Where required by the authority having jurisdiction, the
installation must conform to the Standard for Controls and
Safety Devices for Automatically fi red Boilers, ANSI/ASME
CSD-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.
The following steps are all necessary for proper installation
and safe operation of your boiler.
1. LOCATING THE BOILER 5. GAS SUPPLY PIPING
2. FRESH AIR FOR COMBUSTION 6. ELECTRICAL WIRING
3. INSTALLATION - SYSTEM PIPING 7. CHECKING & ADJUSTING
4. CHIMNEY & VENT PIPE CONNECTION
LOCATING THE BOILER
Select level location as centralized with piping system, 1.
and as near chimney as possible.
Place crated boiler at selected location, remove crate 2.
by pulling crate sides from top and bottom boards.
Combustible fl oors: When boiler is to be installed on a
combustible fl oor, a Special Base Plate must be used -
146-14-031 (2-6 Section) or 146-14-032 (7-9 Section).
This boiler must not be installed on carpeting.
Boiler is to be level. Metal shims may be used under 3.
base legs for fi nal leveling.
Equipment shall be installed in a location in which the 4.
facilities for ventilation permit satisfactory combustion
of gas, proper venting, and maintenance of ambient
temperature at safe limits under normal conditions of
use. Equipment shall be located so as not to interfere
with proper circulation of air. When normal infi ltration
does not provide the necessary air, outside air shall be
introduced (See Page 6 - “Fresh Air for Combustion”).
Advise owner to keep air passages free of obstructions. 5.
Ventilating and combustion air must enter boiler room
without restrictions.
The boiler shall be installed such that the automatic 6.
gas ignition system components are protected from
water (dripping, spraying, rain, etc.) during appliance
operation and service (condensate trap, control
replacement, etc.).
