Boiler Repair
Pre-bid walk-through of building on 10/16/2009.
The intent of this project is to dismantle the #2 boiler and replace section(s) found to be
defective. Contractor shall obtain the required permit from the Town Building Department.
The scope of work is as follows:
o Isolate, drain and disconnect the boiler from the various systems – heating hot water
supply and return, breeching, gas and oil. Breeching and fuel lines shall be capped
during repairs. As this boiler contains a glycol/water mix, the boiler shall be drained into
plastic drums. Draining to storm or sanitary sewer is not permissible.
o Remove the jacket, controls and gas/oil burner as required.
o Dismantle all eight sections. At the contractor’s discretion, the front or back section may
be left in place but, in any case, the fuels and flue shall be capped during repairs.
o Remove rope and waterside gaskets and wire brush clean all gasket surfaces.
o All waterside gasket seating surfaces (including both sides of each intermediate section)
shall be checked for cracks using Liquid Dye Penetrant.
o Sections found to be defective shall be removed from the premises. New section(s) and
gaskets are to be provided by the contractor.
o The boiler shall be reassembled with new section(s), if any, and new gaskets suitable for
glycol/water mix. Strict attention shall be paid to the manufacturer’s installation
instructions, including torque requirements.
o Once the boiler is assembled, it shall be hydrostatically tested at 40 psi for 4 hours. A
representative from the Town of Stratford shall verify no pressure drop during the
testing.
o After satisfactory testing, the boiler shall be drained, flushed of all loose sediment, and
reconnected to the building services heating hot water supply and return (reusing the
stored glycol/water mix) and flue.
o The burner shall be remounted on the boiler and fuels reconnected. Reinstall controls
previously removed.
o The burner shall be test fired and adjusted for maximum efficiency on gas and oil.
Check the fireside of the boiler for leaks.
o Reinstall the boiler jacket and put the boiler on line.
