SECTION III: GENERAL INFORMATION
FEATURES
The
LAARS
EVERHOT ® IGE 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 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 under the
“Temperature Adjustment” section of 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 IGE series water heaters are designed to be installed outdoors on an outside wall. The
water heater is compact (23 5/8” (60 cm) H x 13 3/4” (34.9 cm) W x 8 7/8” (22.6 cm) D) and
mounts on an outside wall using the supplied wall bracket. No indoor 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.
• No venting system required. For outdoor installation only.
• An optional recess box is available which allows the water heater to be recessed into an outside
wall and conceal the piping behind a cover for a more attractive installation. The box enclosure
dimensions are: 40 1⁄2” H x 14 3⁄4” W x 9 1⁄2” D. Contact your
Laars
supplier to order this
optional accessory.
• 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 included, remotely mounted Main Control may be conveniently located near the point of use
and is adjustable from 98-160 ° F for residential models (IGE-199R series), or 98-185 ° F for
commercial models (IGE-199C series). In addition to the Main Control, up to two optional
controls are available for setting the temperature in the bathroom fixtures or other remote
locations.
• All the controls also display fault codes if the water heater malfunctions to assist with servicing
the water heater.
• The heat exchanger coil is provided with anti-freeze heaters for cold climate conditions for
protection as low as -30 ° F (-34 ° C). Solenoids should be installed to drain the water heater in the
event of a power failure.
• The water heater is very quiet in operation.
