Installation Instructions
STEP 1: 
Drain the tank
Turn off the water, 
power and gas 
supply. Attach a 
garden hose to the 
drain valve and 
empty the tank. 
Turn on a hot water 
faucet to allow air into the system to help it drain.
STEP 2: 
Disconnect 
the gas and 
water lines
Disconnect the gas 
line. Disconnect the 
water lines above 
the tank using two 
adjustable wrenches 
or pipe wrenches. If the piping was soldered into 
place, use a tubing cutter to cut the pipe.
STEP 3: 
Detach the gas 
exhaust from 
the ue hat
Using a screwdriver, 
remove the screws 
connecting the vent 
to the water heater. 
Remove the old 
water heater. The water heater may be lled with 
sediment, so it may be heavier than a new one.
STEP 4: 
Set the new 
water heater 
in place
Install in an area with 
at least 6 inches of 
clearance on all 
sides for ventilation. 
Allow unobstructed 
access to the burner and controls. Place a 
carpenter’s level on the side of the water heater and 
level it with plastic shims if necessary. Reconnect 
the ue hat to the gas exhaust vent.
STEP 5: 
Install 
 water  line 
 connections
Measure and cut 
the water line 
connections to 
length. Reconnect 
the water line. 
A variety of installation kits are available to make 
this step easier.
STEP 6: 
Connect the 
gas supply line
Clean gas line 
threads with a wire 
brush or rag. Apply 
piping compound to 
the threads of the 
black pipes as you 
connect them. Assemble and tighten each tting 
with two pipe wrenches. Install the union tting last 
because it connects the new line to the existing line. 
When nished, open the gas supply valve. Test for 
leaks by applying a wet, soapy sponge to the new 
gas ttings. Check for bubbles. If there is a leak, 
bubbles will form on the surface and you will have 
to ret the joint. 
STEP 7: 
Test the water 
lines for leaks
Turn on the water at 
the tank, then turn on 
one or more hot 
water faucets to 
bleed air out of the 
system. Inspect the 
water lines for leaks.
STEP 8: 
Light the pilot
Rotate thermostat 
knob to “pilot” 
position. Press the 
knob in and hold it 
while pressing the 
piezo spark 
generator button 
once every 10 seconds until pilot is lit. Continue to 
hold the thermostat knob down until the LED 
“STATUS” light begins to blink. Release the knob 
and rotate it to the desired temperature setting. Set 
to a comfortable temperature, usually between 118 
and 123 degrees.
