PFG Series 7 Gas-fired Water Boiler — Boiler Manual

Section II: Service

Also Refer to Additional Instructions Shipped With The Boiler For Specific Control Operation and Troubleshooting.

Verify Proper Operation After Servicing.

Your boiler should be inspected, cleaned and, if necessary, adjusted once a year. A qualified service agency should be called.

To avoid personal injury, before servicing:

1.Disconnect electrical supply.

2.Shut-off gas supply.

3.Allow boiler to cool.

Label all wires prior to disconnection when servicing controls.Wiring errors can cause improper and dangerous operation.

To avoid personal injury, death or property damage, keep the boiler area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

Do not block flow of air to boiler. Incomplete combustion and carbon monoxide emissions can cause severe personal injury, death or substantial property damage.

Do not store sources of hydrocarbons (i.e., bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) in boiler area. This can contribute to shortened boiler/vent system life.

Handling ceramic fiber and fiberglass materials

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 possible cause of cancer through inhalation. The combustion chamber lining or base insulation panels in this product contain ceramic fiber materials. 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).”:

Suppliers of fiberglass wool products recommend the following precautions be taken when handling these materials:

Precautionary measures

Avoid breathing fiberglass dust and contact with skin or 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 condi- tions. Current 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.

Wear long-sleeved, loose fitting clothing, gloves, and eye protection.

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.

Operations such as sawing, blowing, tear out and spraying

may generate airborne fiber concentration requiring ad- ditional protection. 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.
