WARNING This water heater needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air. Insufficient air supply will cause a recirculation of combustion products resulting in contamination that may be hazardous to life. This will result in carboning or sooting of the combustion chamber, burners, and flue tubes and creates a risk of asphyxiation. This water heater requires its own separate venting system. DO NOT connect t

SECTION III: GENERAL INFORMATION FEATURES This water heater contains the following features: MAIN POWER ON/OFF SWITCH – The front panel of this water heater has a lighted ON/OFF switch, which is illuminated when the main power is turned on to indicate power to the water heater. COMBUSTION SYSTEM – This water heater is equipped with a self-compensating negative pressure pre-mix combustion system. As the blower operates, air is drawn in through the air intake and into a venturi,

LATCHES – The latches allow easy access for servicing the water heater from the top. Simply remove the two latches for servicing and re-latch upon completion. No tools are required to obtain access to the top of the water heater. MIXING VALVE – This water heater is supplied with an ASSE approved mixing valve to reduce the potential for scald injury when thermostat settings over 120˚F (49ºC) are used for dishwashers or other appliances. The mixing valve reduces the discharge temperatur

CONDENSATE DRAIN – The water heater should either be raised several inches above the floor on a concrete slab or use a low profile condensate pump to allow free drainage of condensate from the elbow drain fitting. This water heater is a condensing type unit and requires a drain to be located in close proximity to allow the condensate to drain safely. The condensate drains from the unit at the exhaust elbow located near the bottom of the unit. The preferred connection to the drain fitting

SECTION IV: INSTALLATION INSTRUCTIONS WARNING INSTALLATION OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD. PLUMBING, AIR SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK ARE REQUIRED. DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING: • Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in detection of the gas

Sacrificial anode rods have been installed in the tank head of the water heater to extend tank life. The removal of these anodes for any reason will nullify the warranty. 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. If this should happen, alternative anodes may be purchased from the supplier that installed this water heater. This will minimize the odor while protecting

REMOVE CRATE 1. Remove all banding and pry off crate sides carefully so as not to damage the water heater. 2. Carefully roll/lift the water heater from the crate base. CAUTION Do not drop water heater. Do not bump water heater jacket against floor. Do not bump exhaust vent pipe against crate or other objects. This will damage the water heater and cause it to be inoperable or create nuisance problems. MOVE WATER HEATER TO PERMANENT POSITION by sliding or walking. Place drain

MECHANICAL EXHAUSTING OF ROOM AIR 1. Where an exhaust fan is installed in the same room with this water heater and combustion air is drawn from inside the room, sufficient openings for air must be provided in the walls. UNDERSIZED OPENINGS WILL CAUSE AIR TO BE DRAWN INTO THE ROOM THROUGH THE WATER HEATER’S VENTING SYSTEM, CAUSING POOR COMBUSTION THAT MAY BE HAZARDOUS TO LIFE. SOOTING MAY RESULT IN SERIOUS DAMAGE TO THE WATER HEATER AND RISK OF FIRE OR EXPLOSION, WHICH CAN ALSO CREATE

SECTION V: WATER CONNECTIONS WARNING Failure to install and maintain a new, listed temperature and pressure relief valve will release the manufacturer from any claim, which might result from excessive temperature and pressures. Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE. To prevent the possibility of injury under these conditions,

required by these appliances, you might create the potential for scald injury. To protect against injury, you must install the ASSE approved mixing valve supplied with the water heater in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch supply lines. Follow the instructions supplied with the mixing valve for proper installation and adjustment. The following chart details the relationship of water temperature and time with reg

CAUTION Check to make sure flue gases do not recirculate into the air intake terminal when using direct venting. If the water heater is having service issues, flue recirculation may be a contributing factor. Even when the minimum vent terminal separation distances are followed, recirculation may still occur depending upon the location outside the building, the distance from other buildings, proximity to corners, weather conditions, wind patterns, and snow depth. Periodically

VENTING The venting instructions must be followed to avoid restricted combustion or recirculation of flue gases. Such conditions cause sooting or risks of fire and asphyxiation. This water heater can be installed as either a direct vent system or power vent (air from inside) system. If it is installed as a direct vent system, then the air intake and the exhaust vent are piped to the outside. If a power vented system is used, then air is drawn from inside and only the exhaust is pip
