*100 Gallon Model Shown. Gas Input Rate The gas input rate of this water heater is affected by several environmental factors such as: • The heating value of the gas • The air and gas densities (which vary widely due to barometric pressure and temperature changes) • Venting installations (pipe diameter, length and fittings) • Altitude When measuring the input rate these factors should beincorporated into the calculations. Also measure the gas consumption over a sufficiently long time to obtain an accurate gas consumption rate (e.g. 3-5 minutes, not onerevolution of the meter needle). Long vents and each additional elbow, inherently reduce the gas input rate due to increased resistance to movingcombustion air and flue gases. The approximate maximum/ minimum input for the 100k, 130k, 150k, 175k, and the 199k models is shown in figure 14. WATER PIPING SYSTEM Piping Installation Piping, fittings, and valves should be installed according to the installation drawing (figure 15). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. Water supply pressure should not exceed 80% of the working pressure of the water heater. The working pressure is stated on the water heater’s data plate. If this occurs a pressure reducing valve with a bypass should be installed in the cold water inlet line to the entire system. This should be placed on the supply to the entire structure in order to maintain equal hot and cold water pressures. Important: Heat cannot be applied to the water fittingson the heater as they may contain nonmetallic parts. If solder connections are used, solder the pipe to theadapter before attaching the adapter to the hot andcold water fittings. Important: Do not install this water heater with iron or galvanized piping. Use brass caps on all unused inlet/ outlet connections. 1. Install the water piping and fittings as shown in figure 15. Note: If state or local codes require, install a vacuum relief valve per the manufactures instructions in thecold water supply line. Connect the cold water supply(50 gal. and below use 1” NPT, 100 gal. use 1-1/2” NPT) to the fitting marked “COLD INLET”. Do not turnthe cold water nipple. The mark should remain along the top side of the nipple (34 & 50 gal models only.) Connect the hot water supply (50 gal. and below use1” NPT, 100 gal. use 1-1/2” NPT) to the fi tting marked “HOT OUTLET”. 2. Always use a suitable grade of joint compound and becertain that all fittings are tightened properly. 3. The installation of unions in both the hot and cold water supply lines is recommended for ease of removing thewater heater for service or replacement. 4. If installing the water heater in a closed water system, install an expansion tank in the cold water line as specified under “Closed System/Thermal Expansion” (Page16). 5. Install a shut-off valve in the cold water inlet line. It should be located close to the water heater and be Figure 14: Input Graph easily accessible. Know the location of this valve andhow to shut off the water to the heater. 6. The Polaris® gas water heater is shipped with a factory- installed Temperature and Pressure Relief Valve. Install a discharge line in the opening in the T & P valve (see instructions on Page 18). 7. After piping has been properly connected to the waterheater, remove the aerator at the nearest hot water faucet. Open the hot water faucet and allow the tankto completely fill with water. (To prevent damage to the unit, DO NOT connect power until the tank isCOMPLETELY FILLED). To purge the lines of any excess air, keep the hot water faucet open for 3 minutes after a constant flow of water is obtained. Close the faucet and check all connections for leaks. Corrosion and Water Quality Water quality will vary from location to location and may contain contaminates that may reduce the life or performance of the water heater. To test for contaminates a water quality test kit is available, reference part number 6903791. Contaminates which can reduce the life or performance of the water heater if present in high quantities include those which contribute to hardness (dissolved minerals such as sodium, calcium and magnesium); plus chlorides and sulfates. Additionally, water that is too acidic or basic (measured as pH) can reduce the life of the water heater. Water treatment systems (such as water softeners for hardness) should be used and maintained properly if the contaminate levels exceed the following: Warranty is void in applications which exceed the water quality requirements listed below. Total Hardness: 12 grains per gal. (205 mg/liter) max. Chloride: 200 mg/liter max. pH: 6.5-8.0 Alkalinity: 200 mg/liter max. 16 Figure 15: Typical One-Temperature System Piping Installation Tempering Valve Installation A tempering valve has been provided for use with the Polaris® Gas water heater and must be installed, per the manufacturer’s instructions, in the domestic hot water line. See Figure 16 for...
