PRODUCT INFORMATION Typical Outdoor Water Heater (No Venting Required) This water heater is for OUTDOOR installation only. DANGER: Product Information DO NOT install this water heater indoors or in an enclosure. It is designed for outdoor installation only. Any other type of installation will result in death or serious personal injury.
USING YOUR WATER HEATER Safety Precautions WARNING: Flammable vapors can be drawn by air currents from surrounding areas to the water heater. Vapors can ignite causing death, personal injury, or product damage. •D O NOT store or use flammable or combustible materials (gasoline, paint thinner, adhesives, newspapers, rags, mops, etc.) in the vicinity of the water heater or any other gas appliance.
USING YOUR WATER HEATER Setting the Water Temperature (cont.) Maximum water temperature occurs while the water heater burner is on. To determine the water temperature: Turn on the hot water faucet and place a thermometer in the water stream. NOTICE: Water temperature at the faucet may vary depending on the season and the length of pipe from the water heater. Use Instructions The remote control temperature range is between 100°F (38°C) and 120°F (49°C).
CARING FOR YOUR WATER HEATER Water Heater Inspections Venting System (Direct Vent Only) The venting system should be inspected annually to ensure all of the vent sections are secure and airtight. Qualified service personnel are familiar with vent system inspections. WARNING: Do not operate the water heater if the vent system shows signs of leaking exhaust. Leaking exhaust could lead to death, personal injury, and/or product failure.
CARING FOR YOUR WATER HEATER Water Heater Inspections (cont.) Burner Visually inspect the main burner annually. DANGER: Shock Hazard – Removing the front cover panel exposes you to live electricity. Electric shock will cause death or serious personal injury. Burner Sight Glass 3 While the water heater is operating, inspect the main burner flames through the burner sight glass. The flames should be blue when the main burner is firing. 1 Remove 4 screws and the unit cover panel.
CARING FOR YOUR WATER HEATER Care and Cleaning DANGER: Shock Hazard – Make certain power to the water heater is OFF before removing protective cover for any reason. Electric shock will cause death or serious personal injury.

INSTALLATION INSTRUCTIONS Water Supply CAUTION: This water heater MUST ONLY be used with the following water supply conditions to prevent product damage and operation failure. A thermal expansion tank will be required if the water heater is installed in a recirculation system. This prevents damage to the heater, related piping, and the relief valve.
INSTALLATION INSTRUCTIONS Water Supply Water Supply Connections (cont.) To ensure proper operation of the water heater, follow these water pressure guidelines. • Operation of the water heater requires a minimum water pressure of 14 psi (97 kPa) and a minimum water flow rate of 0.4 gpm (1.5 lpm). • Water pressure of 40 psi (276 kPa) is required to achieve maximum flow rate. Plumbing •T o maintain proper performance, there must be sufficient water supply pressure. Required Water Pressure = Min.
INSTALLATION INSTRUCTIONS Water Supply Installation (cont.) NOTICES: 4 Open the shut-off valve in the COLD water Inlet line to check the water flow through the water heater. •B e sure to connect the COLD water inlet and the HOT water outlet as shown on the water heater. If reversed, the water heater will not function. • The flow rate of HOT water may vary when more than two faucets (appliances, fixtures, etc.) are being used simultaneously. • The pipes MUST be completely drainable.
INSTALLATION INSTRUCTIONS Water Supply (cont.) Relief Valve A new pressure-relief valve, complying with the Standard for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22/CSA 4.4, must be installed at the HOT water outlet connection of the water heater during installation.

INSTALLATION INSTRUCTIONS Hot and Cold Pipe Insulation Installation WARNINGS: •W hen pipe insulation is not rated for the appropriate weather conditions, install electric heat tracing or equivalent to prevent freezing of the pipes. • Do not insulate or block drain valve on the hot outlet fitting. • If pipes are allowed to freeze, the water heater and the pipes may malfunction or leak due to freezing water.
INSTALLATION INSTRUCTIONS Gas Supply Gas Supply Connections WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Doing so could result in death, personal injury, explosion or fire, product damage, and/or poor operating conditions or performance.
INSTALLATION INSTRUCTIONS Gas Piping 2. Use the table for your gas type to find the pipe size required for your cubic feet per hour of gas and your pipe length. Pipe-Sizing Procedure – Example The gas supply must be capable of handling the entire gas load at the location. Gas line sizing is based on gas type, the pressure drop in the system, the gas pressure supplied, and gas line type. For gas pipe sizing in the United States, refer to the National Fuel Gas Code, NFPA 54.
INSTALLATION INSTRUCTIONS Gas Supply (cont.) Gas Supply Installation 4 1 Gas Supply Install the manual gas appliance shut-off valve to the gas connection at the water heater. The shut-off is supplied with the water heater. Using the proper-size piping, fittings, and components, build the gas supply line to the water heater. NOTICE: The gas supply line should be a minimum of 3/4-in. (1.9-cm) black steel pipe or other approved gas piping material.
INSTALLATION INSTRUCTIONS Leak Testing WARNING: Never use an open flame to test for gas leaks, because death, personal injury, and/or property damage can result. The water heater and its gas connections MUST be leak-tested at normal operating pressures before the unit is placed in operation. These tests should also include all factory connections. Turn on the gas shut-off valve(s) to the water heater. Use a soapy water solution to test for leaks at all the connections and fittings.
INSTALLATION INSTRUCTIONS Gas Supply (cont.) High-Altitude Installation NOTICES: The water heater is certified for installations up to 3,280 ft. (1,000 m) above sea level. The input rating of this water heater is based on sea level operation. At higher elevations, the actual input rate may be lower than the value listed on the rating label. •F or installations above 3,280 ft. (1,000 m) elevation, contact a qualified service technician to make the proper altitude adjustments.
