Gas Piping
The guidelines and examples we have provided in this manual section are for reference only.
The sizing and installation of the gas system for this water heater, as with any gas appliance, is
the sole responsibility of the installer. The installer must be professionally trained to do such work
and must always follow all local and national codes and regulations. Gas line sizing calculations
must be performed for every installation. Please contact Electrolux Home Products, Inc. at 1-888-
360-8557 if you have any questions or concerns.
Gas Type
The gas type indicated on the water heater rating plate (NG or LP) must match the type of gas being
supplied to the water heater.
Gas Conversions
If the gas type supplied does not match the gas type on the rating plate, obtain a replacement unit
with the proper gas type. If a gas type conversion must be made, there are conversion kits available
for some models. [The conversion kit shall be installed by an Electrolux authorized installer/servicer
in accordance with the manufacturer's instructions and all applicable codes and requirements of the
authority having jurisdiction. The Electrolux authorized installer/servicer is responsible for the proper
installation of this kit. Improper installation of this kit will void the warranty.]
Meter
The gas meter must be sized properly for the water heater and other gas appliances to operate properly.
Select a gas meter capable of supplying the entire btuh demand of all gas appliances in the building.
Regulators
Ensure that all gas regulators used are operating properly and providing gas pressures within the speci ed
range of the water heater being installed. Excess gas inlet pressure may cause serious accidents.
Pressure
Check the gas supply pressure immediately upstream at a location provided by the gas company.
Supplied gas pressure must be within the limits shown in the speci cations section with all gas appliances
operating. The inlet gas pressure must be within the range speci ed. This is for the purposes of input
adjustment. Low gas pressure may cause a loss of ame or ignition failure at other appliances in the home,
which may result in unburned gas in the home. Serious accidents such as re or explosion may result.
Measuring Gas Pressure
In order to check the gas supply pressure to the unit, a tap is provided on the
gas inlet. Remove the 9/32" hex head/Philips screw from the tap, and connect
a manometer using a silicon tube. Open up at least 2 xtures and hold in the
maximum manifold pressure button on the circuit board. Please call Electrolux
Home Products, Inc. for details.
NOTE* When checking the supply pressure, make sure to have all other gas appliances turned on
and running.
