AFUE (Annual Fuel Utilization Efficiency) and Heating Capacity is based on the D.O.E. (Department of Energy) test procedure
Ratings shown are for sea level applications. The boiler automatically derates input as altitude increases (See Table 6 and 7 for the approximate rate at given
altitudes). No alterations to boiler are required for altitudes above sea level.
INSTALLATION
STEP 1
—
Rules for Safe Installation and Operation
1. Read the entire installation manual before beginning the
installation. Failure to follow these rules for safe
installation and operation and these instructions could
cause a malfunction of the boiler and result in death,
serious bodily injury, and/or property damage.
2. Check all applicable state and local building codes and
utility company requirements before installation. The
installation must conform with these requirements in their
entirety. In the absence of these codes, use NFPA
Installation Codes and good industry practices.
3. Before servicing the boiler, allow the boiler to cool.
Always shut off any electricity and gas supply connected
to the boiler prior to servicing.
4. Inspect gas line for leaks.
5. Be certain gas input rate is correct. Over firing may result
in early failure of the boiler sections. This may cause
dangerous operation. Under firing may result in too much
air for the pre--mix burner causing poor or loss of
combustion.
A combustion analyzer is required to
properly determine the correct firing rate.
6. Never vent the products of combustion from this boiler to
an enclosed space. Always vent to the outdoors. Never
vent to another room or to inside a building.
7. Be sure there is adequate outdoor air supply to boiler for
complete combustion.
8. Follow a regular service and maintenance schedule for
efficient and safe operation.
9. Keep boiler area clean of debris and free of combustible
and flammable materials.
10. Proper through the wall or through the roof combustion
venting shall be in accordance with the materials and
methods described in this manual. Installation must
comply with local codes.
11. This boiler and related hot water heating systems are not
do it yourself items. They must be installed and serviced
by qualified professionals.
STEP 2

Before Installing the Boiler
Complete all of the following prior to installing the boiler.
CODES
This boiler product is a gas--fired, direct vent, condensing boiler
and must be installed in accordance with all applicable federal,
state and local building codes including, but not limited to the
following:
United States
-- Installation shall conform with National Fuel
Gas Code (NFPA--54/ANSI Z223.1-- latest edition)
Canada
-- Installation shall be in accordance with CSA--B149.1
and .2 installation codes.
Where required by the authority having jurisdiction, the
installation must conform to the American Society of Mechanical
Engineers Safety Code for Controls and Safety Devices for
Automatically Fired Boilers, No. 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 --
latest revision.
Installers
-- Follow local regulations with respect to installation
of CO (Carbon Monoxide) Detectors. Follow maintenance
recommendations in this manual.
BOILER SIZING
Check to be sure you have selected the boiler with the proper
capacity before continuing the installation. The I=B=R Rating of
the boiler selected should be greater than or equal to the
calculated peak heating load (heat loss) for the building or area(s)
served by the boiler and associated hot water heating systems.
(See Table 1.)
Heat loss calculations should be based on approved industry
methods.
CONSIDERATIONS FOR BOILER LOCATION
Before selecting a location for the boiler, the following should be
considered. Each boiler considered for installation must be:
S
Supplied with the correct type of gas (natural gas or
propane).
S
Connected to a suitable combustion air intake piping
system to supply the correct amounts of fresh (outdoor)
air for combustion (maximum length 60 ft).
S
Connected to a suitable venting system to remove the
hazardous products of gas combustion (maximum
length 60 ft).
S
Connected to a suitable hot water heating system.
S
Supplied with a suitable electrical supply for all boiler
motors and controls.
S
Connected to a properly located thermostat or operating
control (not included with boiler).
S
Placed on level surface (must NOT be installed on
carpeting).
S
Condensate drain line must be pitched down to floor
drain or external condensate pump with reservoir at 1/4
in. per foot (wood frame or blocks may be used to raise
boiler).
