INSTALLATION GUIDE

NOTE

: THIS WATER HEATER MUST BE INSTALLED TO MEET THE CURRENT NATIONAL ELECTRIC CODE, 

AND ANY APPLICABLE LOCAL PLUMBING, ELECTRICAL, HEATING AND AIR CONDITIONING CODES AS 
WELL AS THE FOLLOWING MANUFACTURER’S REQUIREMENTS:

WARNING

: YOUR ECCOTEMP MUST BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL. DAMAGE 

TO YOUR UNIT, SERIOUS PERSONAL INJURY OR DEATH MAY OCCUR IF INSTALLED OR HANDLED 
IMPROPERLY. CARE MUST ALWAYS BE USED TO AVOID ELECTRICAL ACCIDENTS WHEN INSTALLING 
OR SERVICING. NEVER USE PARTS THAT ARE NOT ORIGINAL EQUIPMENT OR APPROVED ALTERNATE 
REPLACEMENT PARTS.

GENERAL

Unpack the water heater from the shipping carton carefully. 

DO NOT CUT THE SHIPPING CARTON 

WITH A SHARP INSTRUMENT

. Stand the unit upright and remove the plastic wrap. Locate the four (4) 

mounting holes in the metal back plate. Position the unit against the wall with the two inlet and outlet 
fitting tubes pointed up toward the ceiling. Refer to Mounting Clearances in this section of the manual. 
Make sure the unit is level and attach to the wall with inch or larger lag bolts that are at least 1 ½ 
inches long. If attaching to sheet-rock or paneling, anchors or molly bolts should be used to prevent 
the screws from pulling through the wall. If the water heater is to be installed on a cinder block or 
concrete wall, attach a ½ or ¾ inch section of plywood (20 x 20 inches square) to the wall first, then 
use wood screws to attach the water heater to the plywood.

PROPERTY DAMAGE PROTECTION

WHEN INSTALLING THE Eccotemp IN ANY AREA THAT IS NOT READILY VISIBLE OR ROUTINELY 
MONITORED INCLUDING CLOSETS, CABINETS, ATTICS OR ANY OTHER AREAS WHERE LEAKS OF ANY 
NATURE COULD CAUSE PROPERTY DAMAGE, A 150-PSI MAXIMUM PRESSURE RELIEF VALVE WITH 
DRAIN LINE AND A DRAIN PAN AND DRAIN LINE SUITABLE FOR CONTAINING THE FLOW OF WATER 
PROVIDED BY THE SUPPLY LINE MUST BE INSTALLED. WHEN LEAVING YOUR HOME FOR MORE THAN 
TWO DAYS, TURN OFF THE SUPPLY WATER OR ALTERNATIVELY THE POWER TO THE HEATER.

PLUMBING CONNECTIONS

ATTACHING THE WATER SUPPLY

WARNING #1: Always use two wrenches

 when making any attachments of the water supply. Hold 

the water heater’s inlet and outlet fittings secure while attaching the cold water and hot water lines. 
Never attempt to attach water lines to the heater’s fittings without using a second wrench to hold the 
fittings secure. The heater’s inlet and outlet fittings are designed to turn freely.

WARNING #2: Never solder

 water supply lines to the water heater’s fittings. Heat from the soldering 

may damage the heat exchanger.

WARNING #3: Do not use Plumber’s Putty or PVC/CPVC primer and glue 

on the threads of the water 

heater’s inlet and outlet fittings. Some of the putty compounds on the market are very aggressive 
and could potentially dissolve the threads on the heater’s fittings. PVC/CPVC primer and glue will also 
dissolve the threads on the heater’s fittings. Teflon Tape is the only sealer that should be used on the 
threads of the inlet and outlet fittings.
