2 CONGRATULATIONS! You have just purchased one of the finest water heaters on the market today! This installation, operation and instruction manual will explain in detail the installation and maintenance of your new Powered Direct Vent Series Gas - Fired Residential Water Heater.
3 TABLE OF CONTENTS page GENERAL INFORMATION ............................................................ 4 INSTALLATION. ............................................................................. 5 Locating The Water Heater .......................
4 GENERAL INFORMATION This gas - fired water heater’s design is certified by CSA International under the American National Standard Z21.10.1 - ( as indicated on the rating plate) and CSA 4.
5 General Information continued - A sacrificial anode is used to extend tank life. The removal of this anode, for any reason, will nullify the wa rranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and the impurities in the water.
6 Installation (Locating The Water Heater) continued - Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors.
7 Installation (Locating The Water Heater) continued - The water heater must be located close enough to the outside wall to keep the venting distance within the maximum distance described in the installation instructions. Read the venting section in this installation instruction manual bef ore locating the water heater.

The water heater may be installed on either a combustible or non - combustible floor.
9 Venting continued - (F) The vent sy stem must be inspected at least once a year to ensure against leakage of exhaust products. Exceptions For Installations in Canada: (A) The vent terminals must be located at least 1 foot (.
10 Venting continued - Venting Installation Instructions For Supplied Intake Venting: 1. Refer to Figure 1, “Vent Assembly Illustration” to install intake venting as described below. 2. Insert one end of the Vertical Pipe into Metal Boot on the lower ba ckside of the water heater.
11 Venting continued - Figure 1 Vent Assembly Illustration INTERNET VERSION FOR REFERENCE ONLY.
12 Venting continued - Venting System Condensation Condensate formation does not occur in all installations of power vented heaters, but should be protected against on installations where condensation can form in the venting sys tem.
13 Venting continued - 3. In order to prevent condensate from draining back into the blower (vertical or horizontal runs), a drain tee and condensate trap can be installed in the horizon tal vent as close as practical to the blower vent connection (see Figure 2).
14 Venting continued - This water heater is a power direct vented appliance and is designed to intake and exhaust its products of combustion through 3” (7.6 cm) or 4” (10.2 cm) diameter Schedule 40 PVC pipe to the outdoors. This water heater may intake and exhaust either through the wall or vertically through the roof.
15 Venting continued - EXAMPLE: The exhaust has two 90° elbows and the intake has four 90° elbows. The total feet of straight pipe on the exhaust is 15 ft. (4. 6 m) and the total feet of straight pipe on the intake is 20 ft (6.1 m). Figure 3 six 90° elbows x 5 ft.
16 Venting continued - TABLE 2 - VENT CONNECTOR LENGTHS FOR 3” (7.6 cm) DIAMETER PVC Total # of 90° elbows (Intake + Exhaust) Maximum # of feet of straight pipe (Intake + Exhaust) 2 70 (21.3 m) 3 65 (19.8 m) 4 60 (18.3 m) 5 55 (16.8 m) 6 50 (15.2 m) 7 45 (13.
17 Venting continued - NOTE : ABS or CPVC pipes may be substituted for PVC pipe. Do not mix ABS and PVC pipe in the same installation. THROUGH THE WALL VENTING: Cut a 3 1/2 in. (8.9 cm) diameter hole in the wall at the point where the vent connector is going to pass through the wall.
18 Venting continued - THROUGH THE WALL VENTING WITH LOW GROUND CLEARANCE: When venting cannot exit through the wall at a height greater than or equal to 12” (30.5 cm) above the ground or anticipated snow level, the installation must be modified as shown below (see Figure 6).
19 Venting continued - TABLE 4 3” (7.6 cm) PVC VENT CONNECTOR LENGTHS FROM INSIDE WALL FOR LOW GROUND CLEARANCE INSTALLATIONS Terminating # of Elbows (intake + exhaust) Maximum # of Feet o f Straight Pipe (intake + exhaust) (2) 90 ° Elbows with (1) 90 ° Elbow 2 50 ft (15.
20 (2) 90 ° Elbows with (1) 90 ° Elbow 8 90 ft (27.5 m) INTERNET VERSION FOR REFERENCE ONLY.
21 Venting continued - When venting through the wall, the exhaust terminal must exit the structure at a minimum of 16” (40.6 cm) from either side, or any location above the intake terminal. The exhaust terminal must not be located below the intake terminal for any reason (See Figure 7).

23 Venting continued - HIGH ALTITUDE INSTALLATIONS FOR ELEVATIONS OVER 2,000 FEET (914.5 m) ABOVE SE A LEVEL T he capacity of the induced draft blower declines with increasing altitude due to a reduction in the air density. In order to assure safe and reliable performance of the water heater, the following guidelines must be followed.
24 Water Connections Note: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting off the main water supply, open a faucet to relieve the water line pressure to prevent any water from leak ing out of the pipes while making the water connections to the water heater.
25 Water Connections continued - WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a .
26 Water Connections continued - This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid scalding injury. Cer tain appliances such as dishwashers and automatic clothes washers may require increased temperature water.
27 Gas Connections The gas supply lines must meet all requirements of the National Fuel Gas Code ANSI Z223.1 - (Late st Edition) and/or in Canada CAN/CGA B149 Installation Codes - (Latest Editions). The minimum permissible gas supply pressure for the purpose of input adjustment is 1.
28 Electrical Connections All electrical wiring and connections must be in accorda nce with the National Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian Electrical Code C22.1 (latest edition) and any local codes, which may apply. The water heater must be electrically grounded.
