WARNING! There is water contained in the coils of your water heater at all times. If your water
heater is exposed to freezing temperatures, the water in the coils could freeze, causing a
break in the heat exchanger of the unit, or in the supply and return lines. This kind of damage
will result in water running freely into the space where the water heater is located, which can
cause ooding. DO NOT install this water heater where it may be subjected to freeze. If your
water heater is in an area where freezing is a possibility, you must turn off the water to the
heater and drain it of any water by using the valve stem at the warm water line in bottom of
the unit and disconnect the warm water line. Leave the valve stem and the warm water line
disconnected until you intend to use the water heater.
The MAREY PORTABLE liquid propane gas water heater is capable of supplying 1.5 GPM
(gallons per minute) - 5 (LPM liters per minute). This unit has a standard ½” NPT pipe tting
and an adapter for using a standard garden hose for intel water supply.
Ignition is automatic and powered by 2 “D” cell batteries (not included). Burners start when
water pressure is more than 5 PSI and turn off when water is shut off. A shower head with
multiple spray patterns is included.
For a gas supply a standard 20 pound-propane cylinder (not included) is required. This is
similar to the gas tanks used with outdoor grills. A regulator with a hose is available with the
heater.
An additional safety feature is an automatic 20 minutes shut off timer that is reset each time
operation stops or the shower head is turned off and back on.
