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 ½” H x 14 ¾” W x 9 ½” 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.

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 b
y
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 fo
r
more information.
Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level i
f
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 the outside building structure.

NOT INSTALL INDOORS.
WARNING
Pressure relief valve discharge piping must be piped near the ground or drain to eliminate
potential of severe burns. Insulate and use electrical heat tape around the discharge drain
pipe in any area where freezing could occur. Do not install any shut-off valves, plugs or caps
to the pressure relief valve or discharge piping.
CAUTION
If building cold water supply has a back-flow preventer, check valve or water meter with check
valve, provisions for thermal expansion of water in the hot water system must be provided.
DANGER
Temperature setting should not exceed safe temperature at fixtures. See water temperature
control warnings in the “Temperature Adjustment Section” of this Installation and Operating
Instruction Manual. If higher preheat temperatures are necessary to obtain adequate booster
output, add an ASSE approved mixing valve for hot water supplied to fixtures.
