Instructions for SL 20-115 G1/G2

Warning

Improper installation, adjustment, alteration, service or maintenance can cause property damage,
personal injury, or loss of life. Read and understand the entire manual before attempting installation,
start-up, operation, or service. Installation and service must be performed only by an experienced,
skilled installer or service agency.

Failure to follow all instructions in the proper order can cause personal injury or death. Read all
instructions, including all those contained in component manufacturers’ manuals before installing,
starting up, operating, maintaining, or servicing the appliance.

Warning

The IBC heat exchanger has a small amount of combustion chamber insulation (refractory), which
contains ceramic fibers. When exposed to extremely high temperatures, the ceramic fibers that
contain crystalline silica can be converted into cristobalite, classified as a possible human
carcinogen. Avoid disturbing or damaging the refractory.

If damage occurs, contact the factory for directions. Avoid breathing and contact with skin and eyes
and follow these precautions:

1. For conditions of frequent use or heavy exposure, respirator protection is required. Refer to

the “NIOSH Guide to the Selection and Use of Particulate Respirators Certified under 42
CFR 84” for selection and use of respirators certified by NIOSH. For the most current
information, NIOSH can be contacted at 1-800-356-4676 or on the web at
www.cdc.gov/niosh.

2. Wear long sleeved, loose fitting clothing, gloves and eyes protection.

3. Assure adequate ventilation.

4. Wash with soap and water after contact.

5. Wash potentially contaminated clothes separately from other laundry and rinse washing

machine thoroughly.

6. Discard used insulation in an air-tight plastic bag. NIOSH stated first aid: Eye contact -

Irrigate and wash immediately. Breathing - Provide fresh air
