Liquefied petroleum gas models
Gas detectors are recommended in propane gas applications and their installation should be in
accordance with the detector manufacturer's recommendations and/or local laws, rules,
regulations or customs.
To avoid possible equipment damage, personal injury, or fire, do not connect the water heater to
a fuel type not in accordance with the portable tankless water heater data plate. These portable
tankless water heaters are only for propane gas, not certified for any other fuel type.
Propane appliances should not be installed in an unventilated place (for example, in a basement)
if such installation is prohibited by federal, state and/or local laws, rules, regulations or customs.
Propane gas must be used with great caution. It is heavier than air and will collect first in lower
areas making it hard to detect at nose level.
Before attempting to light the water heater, make sure to look and smell for gas leaks. Use a
soapy solution to check all gas fittings and connections. Bubbling at a connection indicates a leak
that must be corrected.
It is recommended that more than one method, such as soapy solution, gas detectors, etc., be
used to detect leaks in gas applications.
Gasoline, as well as other flammable materials and liquids (adhesives, solvents, paint thinners
etc.), and the vapors they produce are extremely dangerous. DO NOT handle, use or store
gasoline or other flammable or combustible materials any where near or in the vicinity of a water
heater or any other appliance.
●
Notice: If a gas leak is present or suspected:
DO NOT attempt to find the cause yourself.
DO NOT try to light the water heater.
DO NOT touch any electrical switch.
