Water Heater Replacement

Removal of (2) existing condensing heating hot water boilers, and installation of (2) new 750MBH condensing heating hot water boilers including any type of concrete pads if needed for mounting the system to the floor. Informing all personnel affected by this project must be done prior to starting the project. Removal of Existing Boilers (2): Lock out Tag of this system must be done prior to anything being disconnected. All power must be removed from the boilers and all associated equipment prior to their removal. Natural gas shall be valved off before disconnecting any fittings. Once all water, electrical, vent piping and natural gas is valved off and disconnected, the boilers can be removed. Take care to not damage existing water, electrical and natural gas piping and wiring as re-use of these where possible is recommended. Existing 4 PVC vent piping shall be removed to make room for the required 6 vent piping for the new boilers. Discarded equipment and material shall be removed from the VAMC by the contractor. Installation of New Commercial Condensing Gas Boilers (2): New commercial condensing gas boilers shall be brought on site by the installing contractor. The new boilers will be installed in the location vacated by the removal of the old boilers. Existing plumbing, electrical and natural gas should be reconnected. New 6 PVC vent piping shall be installed for the new boilers where the 4 vent piping was removed. The hot water system will need to be balanced and all devices that are served hot water will need to be tested for proper function. The new boilers shall be connected to the existing Marion VAMC Building Automation System (JCI) so that the boilers can be controlled remotely. The water in the hot water loop shall be tested and any needed chemicals should be added to inhibit corrosion in the piping and equipment.
