Pump; Gas Piping; Touchscreen Controller; Water - IBC SL 14-115 G3 Installation And Operating Instructions Manual

CAUTION
The heat exchanger has a small
amount of combustion chamber
insulation (refractory), which
contains ceramic fibers.
When exposed to extremely high
temperatures, the ceramic fibers,
which contain crystalline silica,
can be converted into cristobalite
- which is classified as a possible
human carcinogen.
Care should be taken to 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.

SL 14-115 G3, SL 20-160 G3, SL 30-199 G3 MODULATING GAS BOILERS

4.1.7 Pump

Check that the pump is on in normal operation and that the water Δ°T is reasonable for a
given firing rate (e.g. 10°F between supply and return when firing at 50,000 Btu/hr.).

4.1.8 Gas Piping

Check for damage or leaks and repair as needed.

4.1.9 Touchscreen Controller

• Check that the boiler operation is consistent with the steps in the Touch Screen
Boiler Controller manual.
• Check that the water temperature targets and set-point are satisfactory and that they
have not been adversely amended.
• Check the operating history via the boiler's Logs menu and the Error Logs menu. The
controller tracks the duty cycle of the boiler in each of the four loads separately. This
information can be used to adjust the water temperatures of each load.
• If a problem exists with the controller, consult the Troubleshooting section.

4.1.10 Water

• Check the water pressure and temperature. There should be no noticeable change if
the boiler is functioning normally. Check for any noise in the system.
• Check the water piping for damage or leaks. Repair as needed.
• Check for 12-15 psig in normal operation, and look to ensure pressure does not run up
toward 30 psig at high temperature. If pressure rises sharply, consider replacement of
the expansion tank. Check also for noise at high fire, which may signal water quality
problems.
• Water chemistry shall be of a quality generally accepted as suitable for hydronic
applications. See Section 1.6 for details.
• Ensure any direct "city fill" water connections are left in the closed position to minimize
exposure to leaks and flooding.

4.1.11 Freeze Protection

Check the freeze protection. Use only antifreeze made specifically for hydronic systems.
Inhibited propylene glycol is recommended. Antifreeze volume must not exceed 50% of
the total volume of water in the system.

4.1.12 Boiler Treatment

• Check consistency of any boiler treatment used, for appropriate mixture. Chemical
inhibitors are consumed over time, lowering their density.
• Verify proper operation after servicing.
