Specifications include, but are not limited to: A. General Heating System Replacement — All Types 1. Replace heating systems for health and safety reasons when the heating unit is totally disabled or is in a life-threatening condition. 2. Provide photographs to the Agency to document the furnace conditions that existed prior to the provision of services. The photographs shall include manufacturer’s nameplate, furnace conditions, and any problem(s). 3. Install new heating appliances to manufacturer’s specifications (per manufacturer’s instructions; PMI) following all applicable local, state and national codes. 4. Assess all heating systems for safety. Monitor ambient CO levels during combustion and draft testing. An ambient CO level above 35 ppm is a safety hazard – cease testing immediately. The combustion appliance zone (CAZ) should be ventilated before the resumption of testing and diagnosis of CO problems. 5. Test the gas-piping system for leaks, following the protocol in Section 1(B). 6. Use existing distribution system and fuel supply line to the greatest extent possible, except where they present a hazard. 7. Properly remove and dispose of existing unit. 8. Install the replacement furnace to a dedicated electrical circuit rated or fused to match the amperage of the new system’s requirements for overcurrent protection. 9. Install condensate tubing or piping, or a condensate pump, where needed to reach an appropriate drain (not a sump). Condensate pipes generally may drain to 1) The laundry stand pipe; 2) A new standpipe, indirect or local waste pipe; or 3) A floor drain, when the condensate line can be properly secured to the drain grate and does not pose a tripping hazard to the occupants. Installing a “trip strip”, with the customer’s approval, may be useful to prevent occupants from tripping over the piping. All installations require an air break. Condensate lines cannot be drilled directly into any drain pipe. For more information, see Wisconsin Safety and Professional Standards (SPS), 382.33. Local jurisdictions may vary on acceptable options. 10. Condensate pumps may be installed using an existing (non-GFCI) receptacle accessible without an extension cord, a new GFCI receptacle installed as part of the work, or directly wired per manufacturer’s recommendations. 11. Seal openings in chimneys where natural-draft appliances are eliminated. Seal shall be air tight. Indicate with a written notice on the chimney, where sealed, that the chimney is no longer in use. 12. If asbestos abatement is necessary when replacing a heating unit, required protocols shall be followed by appropriately trained and/or certified persons (see OSHA requirements and Department of Health Services regulations in DHS 159, http://www.dhs.wisconsin.gov/asbestos/). 13. If the work is performed in a pre-1978 dwelling and more than six square feet of interior paint per room will be disturbed, or more than 20 square feet of exterior paint will be disturbed, or any windows are to be replaced or demolished, such work shall comply with DHS Chapter 163 requirements. 14. Provide an owner’s manual with heating-system replacements. Attach the manual to or near the heating system for repeated access. 15. Provide customers with in-home operation and maintenance instructions and a review of safety precautions. 16. Affix to the heating unit a tag, displayed prominently, that identifies who the customer should call for service. The tag information shall have the name, address and telephone number of the service organization.
