Installation Cautions - Electrolux EN18WI30LS Service Manual

* Installation Cautions

Gas Supply Piping
Because a large quantity of gas is used with these appliances, make sure to size the gas meter and supply
piping to match the maximum Btu rating of the heater.
Air Supply and Vent Pipe
Before installation, note the following:
Vent pipe diameters and maximum vent length:
Vent Pipe Diameter
Maximum Vent Length
*Refer to the installation manual for proper settings to achieve this vent length.
Make sure the installation location allows for a flue to be built that will be shorter than the maximum
allowable vent length.
* A longer vent will cause a danger of explosion.
Choose a good path for the vent pipe.
Do not penetrate the vent pipe through a fire wall.
Extend the vent pipe all the way to the outdoors.
Steam and condensed water may exit the vent pipe. Be sure to install the vent pipe so that the steam and
water droplets will not harm anything.
The condensate trap can be filled before connecting the vent pipe.
Filling the condensate trap with water
The condensate trap can be filled before connecting the vent pipe.
Filling the condensate trap before vent pipe installation.
Prior to initial start up, make sure that you fill the condensate trap with water.
DANGER
This is to prevent dangerous exhaust gases from entering the building.
Failure to fill the condensate trap could result in severe personal injury or death.
Please follow one of the procedures described below to ensure that the condensate trap is filled with water.
1) Fill the condensate trap by pouring approx. 30 oz.(850ml) of water into the exhaust accessory on the top
of the appliance as illustrated below.
Or, if the vent pipe has already been installed:
2) After installing the drain pipe, make sure that the area around the appliance is well ventilated; open a
window or a door if necessary.
Then, operate the unit and verify that condensate is coming out of the drain pipe.
(During normal use of the water heater, condensate will begin to discharge from the drain pipe within
15 minutes of use. However, depending on the season and/or installation site conditions, it may take longer.)
Note: The condensate discharged from the water heater has a pH level of approximately 2-3.
If required by local code, the condensate must be neutralized prior to disposal into the sewer system.
Refer to the installation manual pages for additional details.
