When tightened, the nut to heater base clearance should be 3/4” (+/- 1/8”). On 100 gallon models the condensate trap assembly should be glued to the exhaust pipe (see figure 3C). Note: The trap should be aligned so that the exhaust pipe is in a vertical position close to the surface of the water heater. Figure 2: Minimum Clearance Locations Figure 3A: 2” Condensation Trap Installation 100,000 - 150,000 BTU/Hr Models Clearances and Accessibility Notice: Minimum clearances from combustible materials are stated on the data plate located on the front of the water heater. • The water heater is certified for installation on a combustible floor. Important: If installing over carpeting, the carpeting must be protected by a metal or wood panel beneath the water heater. The protective panel must extend beyond the full width and depth of the water heater by at least 3 inches (76.2mm) in any direction or if in a alcove or closet installation, the entire floor must be covered by the panel. The panel must be strong enough to carry the weight of the heater when full of water. Figure 2 may be used as a reference guide to locate the specific clearance locations. A minimum of 24 inches of front clearance and 4 inches on each side should be provided for inspection and service. Figure 3B: 3” Condensation Trap Installation 175,000 - 199,000(50 gal.) BTU/Hr Models Figure 3C: 3” Condensation Trap Installation 100 Gallon Models Figure 4: Condensate Drain Figure 4: Condensate Drain Condensate Drain Line All parts of the condensate trap are glued except for the 1/2” CPVC drain stem joint at the elbow (see figure 3). This assembly can be turned with the outlet of the tee oriented as needed. Once orientation direction is decided, remove the unglued joint from the elbow at the bottom and apply a suitable cement to joint. Re-insert the joint fully and quickly into the elbow making sure to orient it before the cement sets. Connect the remaining piping and run the condensate drain line to a suitable drain. Important: Be sure the drain stem joint is inserted against the stop in the elbow. Failure to do so may result in improper water heater operation. If required by local codes, install a condensate neutralizer cartridge on the drain line (see figure 4). The condensate drain line must be routed to a suitable drain. If no floor drain is available or the drain is above the level of the condensate line, install a condensate pump that is resistant to the acidic condensate. These pumps are available from local distributors. If the pump is not resistant to acidic water, a condensate neutralizer must be used ahead of the pump. When installing the drain line, note the following: • Plastic pipe or tubing must be used to connect the condensate drain to a suitable drain or condensate pump. Do not use copper tubing, iron, or steel pipe for the condensate drain line. • Condensate drain lines should be installed in conditioned areas only. Drain lines installed in areas that are subject to freezing temperatures should be wrapped with a nationally recognized/listed heat tape and/or approved insulation for freeze protection. Install per manufacturer’s instructions. • Do not common drain with the temperature and pressure relief valve or the condensate line from an air conditioner evaporator coil. • Slope the condensate drain toward the inside floor drain or condensate pump. • The condensate drain line and connection to the drain piping must comply with all local codes. • Do not run the condensate line into the drain pan. VENT PIPE SYSTEM Carbon Monoxide Hazard Follow all instructions to locate and install the vent pipe system. Instructions can be found in this manual, in state or local codes (or the authority having jurisdiction), or in the absence of such, theNational Fuel Gas Code, ANSI Z223.1, NFPA 54, Latest Edition. Canadian installations must be performed in accordance with CAN/CGA-B149. Failure to properly locate and install the vent pipe system can result in death or carbon monoxide poisoning. Venting This water heater has a direct vent system in which all air for combustion is taken from the outside atmosphere and all combustion products are discharged to the outdoors. This water heater must be properly vented for removal of exhaust gases to the outside atmosphere. Correct installation of the vent pipe system is mandatory for the safe and efficient operation of this water heater and is an important factor in the life of the unit. Vent pipe installation must be performed in accordance with state and local codes, or in the absence of such, the National Fuel Gas Code, NFPA 54, ANSI Z223.1-latest edition. Canadian installations must be performed in accordance with CAN/CGA-B149. When replacing an existing Polaris unit, it is recommended that the venting system be reviewed for compliance with the requirements contained in this installation manual. If the venting is not in compliance, it is recommended that the appropriate changes be made to bring it into...
