3 BOILER INSTALLATION
3.1 Checking Equipment Before You Install
Inspect the unit completely upon receipt from the freight carrier before signing the bill of lading. Inspect the appliance
and all accompanying parts for signs of impact or mishandling. Verify the total number of pieces shown on packing
slips with those actually received. Contact the freight carrier immediately if any damage or shortage is detected.
3.2 Codes
The equipment must be installed in accordance with those installation regulations in force in the local area where the
installation is to be made. Authorities having jurisdiction must be consulted before installation is made. In the
absence of such requirements, the installation must conform to the latest edition of the National Fuel Gas Code,
ANSI Z223.1. Where required by the authority having jurisdiction, the installation must conform to American Society
of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers, No. (CSD-1).
Where required by the Canadian authority having jurisdiction, the equipment must be installed in accordance with the
latest edition of the Installation Code for Gas Burner Appliances and Equipment CAN/CSA B149 and/or B149.2 and
applicable Provincial Regulations. All appliances conform to the latest edition of the ASME Boiler and Pressure
Vessel Code, Section IV.
3.3 Electrical Requirements
See appliance rating decal for electrical service requirements. The appliance must be electrically supplied and
grounded in accordance with the requirements of the authority having jurisdiction or in the absence of such
requirements, with the latest edition of the National Electrical Code ANSI/NFPA No. 70. In Canada, the electrical
service must conform to local electrical codes and/or CSA C22.1, Canadian Electrical Code, Part 1.
• All wiring between the unit and field installed devices must be made with type T copper wire.
• Line voltage wire exterior to the appliance must be enclosed in approved conduit or approved metal clad cable.
• To avoid serious damage, DO NOT energize the unit until the system and appliance is full of water.
3.4 Location
These units are suitable for indoor installation only.
• The boiler may be installed on a 4 inch to 6 inch housekeeping pad.
• Locate the unit so that if water connections should leak, water damage will not occur. When such locations are
unavoidable, install a suitable drain pan, and plumb pan to ensure adequate drainage in the event of a leak.
Under no circumstances is the manufacturer responsible for water damage in connection with this unit, or any of
its components. The manufacturer’s warranty does not cover water damage.
• Protect associated electrical components and electrical connections from water (dripping, spraying, rain, etc.)
during appliance operation and service.
• Place the appliance on a level, non-combustible floor. Concrete over wood is not considered non-combustible.
• Do not install on carpet or other combustible floor coverings. If installation over a combustible floor is required,
follow these guidelines:
− Use a base of hollow clay tile or concrete blocks from 8" to 12" thick and extending 24" beyond the sides.
− Place the blocks in line so that the holes line up horizontally to provide a clear passage through the blocks.
− Install 1/2" fireproof millboard with a 20-gage sheet metal cover over the block base.
− Center the unit on the base. Also follow this procedure if electrical conduit runs through the floor, and
beneath the appliance. A field-installed base must meet all local fire and safety code requirements.
3.5 Service Clearances
Provide adequate clearances on all sides for installing and servicing connections such as water, gas, vent,
combustion air duct, electrical, pump and other auxiliary equipment. At least 24" above the boiler is required for filter
replacement and burner/gas control service.
3.6 Clearances To Combustible Surfaces
Minimum 1" clearance must be provided from any vent surface to adjacent combustible material. The minimum
clearances to unprotected combustible material are 24" be provided at the front, 8" be provided at the rear and 8" at
top, left and right sides of the appliance.
