avoided, will result in death, serious injury or substantial
property damage.

This appliance has been equipped for residential instal-
lations. If used for commercial applications, any and all
additional code requirements must be adhered to for in-
stallation. This may require additional controls, including
!
but not limited to an external water cut off, a manual reset
high temperature limit, and wiring and/or piping modifi-
cations. The manufacturer is not responsible for any field
installation changes made to a boiler installation which are
not described or acknowledged in this manual.
IMPORTANT: Failure to follow these instructions could
cause a malfunction of the boiler and result in death, seri-
ous bodily injury, and/or property damage. For assistance
or additional information, consult a qualified installer,
service agency, or the gas supplier.
1. Check all applicable state and local building codes and utility
company requirements before installation. This installation
must conform with these requirements in their entirety. In the
absence of these codes, use NFPA installation codes and good
industry practice.
2. Before servicing the boiler, allow it to cool. Always shut off any
electricity and gas supply connected to the boiler prior to servic-
ing.
3. Inspect gas line for leaks.
4. Be certain gas input rate is correct. Over firing may result in
early failure of the boiler components. This may cause danger-
ous operation. Under firing may result in too much air for the
pre-mix burner causing poor or loss of combustion.
5. 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.

NOTICE
!
Indicates an imminently hazardous situation which, if not
avoided, may result in injury or property damage.
Indicates information which should be followed to ensure
proper installation and operation.
6. Be sure there is adequate outdoor air supply to boiler for com-
plete combustion.
7. Follow a regular service and maintenance schedule for efficient
and safe operation.
8. Keep boiler area clean of debris and free of combustible and
flammable materials.
9. 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.
10. This boiler and related hot water heating systems are not do-it-
yourself items. They must be installed and serviced by qualified
professionals. Ratings above are for sea level applications. The
boiler automatically derates input at a rate of 2% for every 1000
feet above an elevation of 2000 feet (see Table 2). The boiler will
also derate relative to the calorific value of the gas being used.
Use the formula specified in "Measure The Natural Gas Input
Rate" in the Control Manual and Troubleshooting Guide (P/N#
240006104) to determine the proper rate due to derated gas. To
ensure proper operation at 5,000 feet of altitude and above, the
minimum RPM setting; parameter 17, must be raised to 3,200.
Instructions on how to change the parameters are included in
the Parameter Guide, part number 240006105.
