Installation and Service Manual

GENERAL PRODUCT INFORMATION

Special Instructions

This manual supplies information for the installation, operation and servicing of the appliance. Read and understand this manual completely before installing unit.

Installation and service must be performed by a qualified service installer, service agency, or the gas supplier.

Unpacking

Upon receiving equipment, check for signs of shipping damage. Pay particular attention to parts accompanying the boiler which may show signs of being hit or otherwise being mishandled. Verify total number of pieces shown on packing slip with those actually received. In case there is damage or a shortage, immediately notify the carrier.

Codes

The equipment shall be installed in accordance with those installation regulations in force in the local area where the installation is to be made. These shall be carefully followed in all cases. Authorities having jurisdiction shall be consulted before installations are made. In the absence of such requirements, the installation shall conform to the latest edition of the National Fuel Gas Code, ANSI Z223.1 and/or CAN/CGA-B149 Installation Code. 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, ASME CSD-1. All boilers conform to the latest edition of the ASME Boiler and Pressure Vessel Code, Section IV.

Note: The ceramic fiber material used in this appliance is an irritant; when handling or replacing the ceramic materials it is advisable that the installer follow these safety guides.

REMOVAL OF COMBUSTION CHAMBER LINING OR BASE PANELS:

•Avoid breathing dust and contact with skin and eyes.

•Use NIOSH certified dust respirator (N95) (http://www.cdc.gov/niosh/hompage.html).

•Lightly mist with water (only those areas being handled) the combustion chamber lining or base insulation to prevent airborne fibers.

•Remove combustion chamber lining or base insulation from the boiler and place it in a plastic bag for disposal.

•Wash potentially contaminated clothes separately from other clothing. Rinse clothes thoroughly.

•NIOSH stated First Aid:

Eye: Irrigate immediately.

Breathing: Fresh air.

WARNING: The combustion chamber lining in this appliance contains ceramic fiber materials. Ceramic fibers can transform into cristobalite (crystalline silica) when exposed to temperatures above 2192°F (1200°C) dependent upon the length of exposure time.*

The International Agency for Research on Cancer (I.A.R.C.) has concluded, "Crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans."**

Testing has confirmed that the ceramic fibers in this application do not reach 2192°F (1200°C).

Warranty

Factory warranty (shipped with unit) does not apply to units installed or operated improperly.

Improper installation or system design causes most operating problems.

1.Excessive water hardness causing a lime build up in the copper tube is not the fault of the equipment and is not covered under the appliance manufacturer’s warranty (see Water Treatment, page 40 and Water Chemistry, page 52.)

2.Excessive pitting and erosion on the inside of the copper tube may be caused by too much water velocity through the tubes and is not covered by the appliance manufacturer’s warranty (see System Temperature Rise Chart on page 37 for flow requirements).
