12 ventilation systems, clothes dryers and replaces shall also be considered in determining the adequacy of a space to provide combustion, ventilation and dilution air . UNUSUALL Y TIGHT CONSTRUCTION In unconned spaces in buildings, inltration may be adequate to provide air for combustion, ventilation and dilution of ue gases.
13 1. 1 square inch per 3000 Btu/hr (700 mm 2 per kW) of the total input rating of all appliances located in the enclosure, and 2. Not less than the sum of the areas of all vent connectors in the space. OUTDOOR AIR THROUGH TWO HORIZONT AL DUCTS FIGURE 6.
14 This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appliance. All piping components connected to this unit for space heating applications shall be suitable for use with potable water .

16 FIGURE 9. CLOSED W A TER SYSTEMS W ater supply systems may , because of code requirements or such conditions as high line pressure, among others, have installed devices such as pressure reducing valves, check valves, and back ow preventers. Devices such as these cause the water system to be a closed system.
17 Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the top cover of the heater .Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.
18 GAS PIPING Make sure gas supplied is same type listed on model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5 kPa) for natural and propane gas (L.P .). The minimum inlet gas pressure shown on rating plate is that which will permit ring at rated input.
19 HIGH AL TITUDE INST ALLA TIONS This high efciency water heater is certied for use without modication for an altitude of 10,000 feet (3,079 meters).
20 VENTING Never operate the water heater unless it is vented to the outdoors. The instructions in this section of the manual must be followed to avoid choked combustion or recirculation of ue gases. Such conditions cause sooting of the combustion chamber , burners and ue tubes and creates a risk of asphyxiation.
