Do Not Overdrive Tubes! Overdriving tubes can cause damage to the tubes and boiler header holes. Use
only approved Thermal Solutions tube driver and specified hammer. The end-formed tube fitting is designed
to deform if overdriven to minimize damage to the vessel tube holes.
10. Reinstall the tube clamps. Replace the nuts and flat washers if damaged in any way. Use brass nuts only!
Tighten the nuts until snug. Do not try to compress the tube-ends into the holes with the clamps, because
the clamps might break or the stud might shear.
11. Refill the boiler. Fill the unit with water and ensure that there is no leakage at the replacement tube-ends
before reinstalling the flue collector panels.
If a leak is detected after a replacement tube has been installed, pressure in the boiler must be reduced
to zero before adjusting tube(s). Adjusting tubes under pressure could result in serious personal injury.
12. Reinstall all flue access doors, door clamps, and jacket panels.
13. Perform startup check prior to putting boiler back into operation.
J. Safety and Operating Controls
All of the safety control devices listed in Table 30 are logically linked to the Concert Boiler Control that supervises
the sequence of operation of the boiler for safe and efficient operation. It does so by ensuring proper light off
and firing of the main burner and if need be, will immediately cut-off gas supply to the main burner when gas
pressure, water temperature, water flow or another critical attribute is outside of the operational settings. It
also varies the combustion rate in real time to meet the desired load of the system.
Do not install, operate, service or repair any components of this equipment unless you are qualified and
fully understand all requirements and procedures. Trained personnel should refer to those who have
completed Thermal Solutions Service School training specific to this product.
