SECTION III: GENERAL INFORMATION

FEATURES

The Bradford White EVERHOT® IGI series tankless water heater is a high output, high efficiency appliance, which heats the water continuously as hot water is being drawn for use. Unlike tank type storage water heaters, this water heater does not store hot water. The burner operates whenever there is a demand for hot water and is off when the hot water flow stops. Hot water is continuously supplied for any length of time required, as long as the specified flow rates are not exceeded. There is no need to set the temperature higher than required for sufficient capacity. The EVERHOT water heater has sufficient capacity to supply several hot water faucets simultaneously. The hot water flow capability will be dependent upon the temperature of the outlet water selected. More detail can be found at the beginning of Section II, “Specifications” section in this Installation and Operating Instruction Manual. Your plumbing professional should determine your hot water requirements before installing this water heater to be sure the capacity is sufficient for your application.

The IGI series water heaters are designed to be installed on or near an outside wall for indoor installation only. The water heater is compact (23 1/2” (59.7 cm) H x 13 5/8” (34.6 cm) W x 8” (20.3 cm) D) and mounts on a wall using the supplied wall bracket. No floor space is needed and the water heater can be mounted at a height convenient for servicing.

The weight is less than 50 pounds (23 Kg) and can be installed by 1 person.

The burners ignite within 3 seconds of water flow (1/2 gallon/minute (1.9 L/m) minimum) by direct spark ignition. There is no standing pilot.

A variable speed combustion air blower forces the combustion air supply into the burner compartment.

Direct vent design uses only outside air for combustion. The venting system is a coaxial design requiring a single 5 1/4” (13.3 cm) hole through the outside wall or roof. Vent pipe fittings have internal gaskets for a tight seal to prevent leakage of flue products and combustion air.

The burner flame is continuously monitored and modulated to match the heating requirements of the water flow. Temperature and flow sensors continually monitor the water flow and outlet water temperature and adjust the burner and combustion air blower to maintain temperature.

The IGI model series have a digital temperature control integrally mounted to project through the front panel of the water heater. The outlet water temperature is adjustable from 96-160°Ffor residential models(IGI-180Rseries) or96-180°Ffor commercial models(IGI-180Cseries). The front panel temperature control also displays fault codes if the water heater malfunctions to assist with servicing the water heater. No installation is required for the main temperature control.

In addition to the main temperature controller, up to two optional bathroom temperature controls are available on the residential models for setting the water temperature in the bathroom fixtures up to 120°F.

The heat exchanger coil is provided with anti-freezeheaters for protection in cold climate conditions to ambient temperatures as low as-30°F(-34°C).Drain solenoids should be installed to drain the water heater in the event of a power failure.

The water heater is very quiet in operation.

SECTION IV: INSTALLATION INSTRUCTIONS

WARNING

INSTALLATION OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED PLUMBER. 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.

Most people recognize this odor as a “sulfur” or “rotten egg” smell.

Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or “fade”, and not be as readily detectable.

If you have a diminished sense of smell, or are in any way unsure of the presence of gas, immediately contact your gas supplier from a telephone in another building.

Gas detectors are available. Contact your gas supplier or plumbing professional for more information.

Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.

IF YOU SMELL GAS:

Do not try to light any appliance.

Do not touch any electric switch; do not use any telephone in your building.

Immediately call your gas supplier from a telephone in another building. Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!

WARNING

This water heater must be located in an area where leakage of the heat exchanger coil, water line connections, or the pressure relief valve will not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such locations cannot be avoided, a suitable drain pan must be installed under the water heater. The drain pan depth must be suitable for draining and collecting water, and have a minimum length and width of at least four (4) inches (10.2 cm) measured from the jacket of the water heater. The drain pan, as described above, can be purchased from your plumbing professional. The drain pan must be piped to an adequate drain. The piping must be at least ¾ inch (1.9 cm) in diameter and pitched for proper drainage.
