Department of Energy – Compliance
EG water boilers only
This boiler is equipped with a control system that automatically adjusts a time delay period to turn on the boil-
er during a call for heat. This is accomplished by circulating available hot water in the system while measuring wa-
ter boiler water temperature changes. The control calculates a suitable delay based on temperature measurements and
turns the boiler on only after it determines that the demand for heat cannot be satisfied with the available hot water,
Due to the wide variety of controls used in boiler installations, this control is also equipped with an adjustment for the calculated time
delay period (ECONOMY ADJUST). In the MIN position, the time delay is zero and the IMPORTANT notice below must be observed:
IMPORTANT
In accordance with Section 325 (f) (3) of the Energy Policy and Conservation Act, this boiler is equipped with a feature that saves
energy by reducing the boiler water temperature as the heating load decreases. This feature is equipped with an override which is
provided primarily to permit the use of an external energy management system that serves the same function.
THIS OVERRIDE MUST NOT BE USED UNLESS AT LEAST ONE OF THE FOLLOWING CONDITIONS IS TRUE:
• An external energy management system is installed that reduces the boiler water temperature as the heating load decreases.
• This boiler is part of a modular or multiple boiler system having a total input of 300,000 BTU/hr or greater.
• This boiler is equipped with a tankless coil.
REMOVAL OF COMBUSTION CHAMBER LINING OR BASE PANELS
Handling berglass and ceramic ber materials
The combustion chamber lining or base insulation panels in this product contains ceramic fiber
materials that have been
identified as carcinogenic, or possibly carcinogenic, to humans
. Ceramic fibers can be converted to cristobalite in very
high temperature applications. The International Agency for Research on Cancer (IARC) has concluded, “Crystalline
silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1).”:

■ Apply enough water to the combustion chamber lining or base insulation to prevent airborne dust.
■ 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 washer thoroughly.
NIOSH stated First Aid.
■ Eye: Irrigate immediately.
■ Breathing: Fresh air.
REMOVAL OF FIBERGLASS WOOL — OR — INSTALLATION OF FIBERGLASS WOOL,
COMBUSTION CHAMBER LINING OR BASE PANELS:
This product contains fiberglass jacket insulation and ceramic fiber materials in combustion chamber lining or base
panels in gas fired products. Airborne fibers from these materials have been listed by the State of California as a pos-
sible cause of cancer through inhalation.
■ Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certified dust respirator (N95). This type of respirator is based on the OSHA requirements for fiberglass wool
at the time this document was written. Other types of respirators may be needed depending on the job site conditions. Cur-
rent NIOSH recommendations can be found on the NIOSH web site at http://www.cdc.gov/niosh/homepage.html. NIOSH
approved respirators, manufacturers, and phone numbers are also listed on this web site.
• Wearlong-sleeved,loosettingclothing,gloves,andeyeprotection.
■ Operations such as sawing, blowing, tear out, and spraying may generate airborne fiber concentration requiring additional protection.
■ Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
■ Eye: Irrigate immediately.
■ Breathing: Fresh air.
