In addition, the installing plumber or gasfitter shall observe that a battery operated or hard wired carbon monoxide detector with an alarm is installed on each additional level of the dwelling, building or structure served by the sidewall horizontal vented gas fueled equipment. It shall be the responsibility of the property owner to secure the services of qualified licensed professionals for the installation of hard wired carbon monoxide detectors. In the event that the side wall horizontally vented gas fueled equipment is installed in a crawl space or an attic, the hard wired carbon monoxide detector with alarm and battery back-up may be installed on the next adjacent floor level. In the event that the requirements of this subdivision can not be met at the time of completion of installation, the owner shall have a period of thirty (30) days to comply with the above requirements provided that during said thirty (30) day period, a bat- tery operated carbon monoxide detector with an alarm shall be installed. approved carBon MonoXIde detectors Each carbon monoxide detector as required in accordance with the above provisions shall comply with NFPA 720 and be ANSI/UL 2034 listed and CSA certified. sIGnaGe A metal or plastic identification plate shall be permanently mounted to the exterior of the building at a minimum height of eight (8) feet above grade directly in line with the exhaust vent terminal for the horizontally vented gas fueled heating appli- ance or equipment. The sign shall read, in print size no less than one-half (1/2) inch in size, “Gas vent dIrectlY Below. Keep clear of all oBstructIons.” InspectIon The state or local gas inspector of the side wall horizontally vented gas fueled equipment shall not approve the installation unless, upon inspection, the inspector observes carbon monoxide detectors and signage installed in accordance with the provisions of 248 CMR 5.08(2)(a) 1 through 4.

When the water heater outlet terminal is low enough to be touched accidentally, or is accessible to small children, a wire mesh chain link fence (as shown in Figure 8) may be used. Care should be taken to maintain adequate ventilation around the outlet terminal. If a chain link fence is installed, it must not be used as a storage area for items that may block proper ventilation. fIGure 9. aIr for ventIlatIon for applIances located In confIned spaces Air for ventilation should be provided if installed in a confined space.

  • Page 12: Installing The New Water Heater

    InstallInG the new water heater water pIpInG therMal eXpansIon As water is heated, it expands (thermal expansion). In a closed system the volume of water will grow when it is heated. As the volume of water grows there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent temperature-pressure relief valve operation: water discharged from the valve due to excessive pressure build up. This condition is not covered under the limited warranty. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. A properly sized thermal expansion tank should be installed on all closed systems to control the harmful effects of thermal expansion. Contact a local plumbing service agency to have a thermal expansion tank installed.

It will harm the dip tube and damage the tank. For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged.
  • Page 14: Gas Piping

    When installed at elevations above 7,700 feet (2,347 meters), input Gas pIpInG rating should be reduced at the rate of 4 percent for each 1,000 feet (305 meters) above sea level which requires replacement of the burner orifice in accordance with The National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact your local gas supplier for further information. Failure to replace the standard orifice with a high altitude orifice when installed could result in improper and inefficient operation of the appliance, producing carbon monoxide gas in excess of safe limits, which could result in serious injury or death. Contact your gas supplier for any specific changes which may be required in your area. Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 10.5 inch water column (2.6 kPa) for natural and 13 inch water column (3.2 kPa) for propane gas (L.P.). The minimum inlet gas pressure shown on the rating plate is that which will permit firing at rated input. All gas piping must comply with local codes and ordinances or with the National Fuel Gas Code (ANSI Z223.1/ NFPA-54) whichever applies. Copper and brass tubing and fittings (except tin lined copper Use pipe joint compound or Teflon tape marked as being resistant tubing) shall not be used.

    sedIMent traps Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater. To fill the water heater with water: 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater. 2. Open the cold water supply valve to the water heater. note: the cold water supply valve must be left open when the water heater is in use.

Plan the layout of the vent system from the vent termination to the water heater considering all of the 90° and 45° elbows plus the number of feet of pipe that would be needed to install the total vent system. The water heater must be vented to the outdoors as described in these instructions. DO NOT connect this water heater to an existing vent or chimney. It must be vented separately from all other appliances. The fittings, other than the supplied Vent Termination should be equivalent to the following: PVC (Schedule 40, DWV, ASTM D-2665), CPVC (Schedule 40, DWV, ASTM F-438), ABS (Schedule 40 DWV, ASTM D-2661). The cement used should be as recommended by the vent pipe manufacturer. See the instructions in the “VENT PIPE PREPARATION” section of this manual for the proper method of cutting and cementing the PVC pipe and fittings.

The main burner should provide complete combustion of gas, ignite rapidly, give reasonably quiet operation, and cause no excessive flame lifting from the burner ports. If the proper flame characteristics are not evident as in Figure 32, make sure that the flow of combustion and ventilation air is not blocked in the venting system. You should also check for sooting. Soot is not normal and will impair proper combustion. A visual inspection of the main burner and HSI igniter assembly should also be done at least once a year, see Figure 32. Soot build-up indicates a problem that requires correction before further use. Turn “OFF” gas to water heater and leave off until repairs are made, because failure to correct the cause of the sooting can result in a fire causing death, serious injury, or property damage.
