Installation Guide

Step 7. Mount the Remote
Control (Optional)
Remote will have a magnet
on the back for easy
mounting directly to the
unit cabinet. If mounting on
the cabinet, skip to step
8; if mounting on a more
accessible wall location,
continue reading.
Select an easily accessible location for the remote to be installed,
such as the laundry room. Secure the remote wall plate to the
wall using the screws provided or appropriate fasteners. The
wall plate may be attached to a standard electrical box and the
remote wire run inside the wall.
If the remote is more than 10 feet from the water heater (the
length of the wire provided), use a 2-conductor, 18-gauge ther-
mostat wire. DO NOT use twisted pair wire, such as telephone
or network cable. They will cause the remote to malfunction.
Connect the remote wire, one to each end of the screw terminals
on the back of the control. Place the wire under one or both
strain reliefs and route the wire out the bottom “knock out” or
into the wall.
Secure the remote to the mounting plate using the small screw to
fasten the remote at the bottom.
See the “Remote Control Installation” section of the “Installation
Instructions” in the Use and Care Manual for details.
Step 1. Mount the Water Heater
After selecting a suitable location as outlined in the Use and Care Manual, locate a sturdy
surface. The water heater should be mounted onto a stud or framing behind the dry wall.
It is not recommended to mount the water heater directly to drywall without some type
of rigid support, such as plywood or stud framing. Appropriate fasteners should be used.
Basic wood screws are provided with the unit.
Mark the center line of the water heater and install the
easy mounting bracket on the wall using the enclosed
screws.
Lift the water heater up and align the keyhole slots on
the back of the unit with the hooks on the mounting
bracket and lower into
place. Level the water
heater and secure with
additional fasteners at
the bottom. Use washers to ensure the water heater is
secured.
See the “Water Heater Installation” section of the
“Installation Instructions” in the Use and Care Manual
for details.
Step 8. Connect Electrical
This water heater plugs into a standard 120VAC, 3-prong
grounded outlet. DO NOT use any ground adapters. The water
heater may be hard-wired if required by local codes. DO NOT
connect this water heater to a GFCI or AFCI circuit. The water
heater only draws a maximum of 3 amps of current. Multiple
water heaters may be installed on the same circuit if needed.
See the “Electrical Wiring” section of the “Installation Instructions”
in the Use and Care Manual for details.
Step 10. Turn On and Test
You are ready to operate your water heater after completing and
verifying Steps 1 through 9 and following any guidelines and
requirements outlined in the “Installation Instructions” in the Use Care
Manual. Complete and fill out the Installation Checklist. Also, fill out
the Product Information block with the water heater’s model and
serial number.
With no fixtures running, turn on the water, the
gas, and the electricity to the water heater. Wait
90 seconds to allow water heater to complete
start up system checks. Press the Power button
on the remote control as it will beep and a green
light will come on. The remote will display “100”
the first time you turn it on.
Press the up arrow key to adjust the unit to your
desired temperature up to 120° F. Higher temper-
atures are available. See “Setting the Water
Temperature” in the Use and Care Manual.
Go to a nearby fixture or faucet, such as a tub,
and turn on the hot water only. The water heater will begin to turn on:
fan first, with a few “clicks” from the gas valve and the igniter until it
lights. Once it has lit, the unit will ramp-up to match the water flow.
Check the water temperature after about 30 seconds. It should be
within a couple degrees of the thermostat setting.
Troubleshooting
If a problem occurs, the unit will stop operating and display an
error code. Note the error code and stop the water flow. The most
common error codes on start-up are:
11 : Failed to ignite: Check the gas and purge any air from lines.
12 : Lost flame: Check the gas supply, maybe insufficient.
29 : Neutralizer not draining: Review Step 4 and check for blockage.
P1 : Not enough water flow: Try another fixture or faucet.
No Display : Check the connections in Steps 2 and 3.
Will Not Power On : Check if water is flowing into the water heater;
check outlet.
Refer to the Use and Care Manual for important information about
maintaining and operating your new tankless water heater.
Step 4. Install Water Lines
The hot and cold water connections are a ¾” NPT male connection. We recommend the
use of Service Valves as these provide an easy means to service the water heater in the
future, such as flushing for hard water scale build-ups.
The piping should be ¾”-diameter copper, or other code-approved material, such as PEX
or CPVC. Piping smaller than ¾” will result in a noticeable loss of pressure on the hot water
side. DO NOT use galvanized pipe or fittings with this water heater.
Seal the threaded connections with an approved
Teflon
®
tape. Pipe dope is not recommended. When
tightening the fittings, use a wrench for support. DO
NOT overtighten as damage to the fittings can occur.
A pressure-only relief valve rated at 150 PSI is
required. Pipe the relief valve to a drain or outside
per local code requirements.
See the “Water Supply” section of the “Installation
Instructions” in the Use and Care Manual for details.
Step 5. Install Gas Lines
A properly sized and installed gas supply is critical to the proper operation of this
water heater. The gas supply connection is a ¾”-male NPT fitting; the minimum
pipe size must be ½” or larger. Flexible connectors may be used; however, the BTU
capacity rating on the connector must exceed the
maximum input rating of the water heater. DO NOT use connectors with a rating
lower than that of the water heater as improper operation can occur.
Seal the threaded connections with an approved pipe thread sealant, such as Teflon
®
tape. When tightening the fittings, use a wrench for support. DO NOT overtighten as
damage to the fittings can occur.
Install the gas shut-off valve, included with the water heater, directly on the gas fitting
on the bottom of the water heater. Connect the gas piping to the valve. It is recom-
mended to have a union near the water heater, as well as a drip leg between the
main gas supply valve and the water heater. Check for any leaks using a soapy water
mix.
See the “Gas Supply” section of the “Installation Instructions” in the Use and Care Manual or the
National Fuel Gas Code for details.
Step 3. Install Vent Termination
This guide covers a basic two-pipe, side wall installation only. Instructions
may vary depending on the termination style and location. Select a
location for the vent termination.
From the outside, locate and mark a
center line for the exhaust vent location.
Mark a center line 5-½” to the right of
the center of the exhaust for the air
intake vent. Ensure that the exhaust
vent location is at least 12” below
or from a window or door. Check all
clearances as listed in the “Venting”
section of the “Installation Instructions” in the Use Care Manual. DO NOT
locate the intake and exhaust more than 24” apart.
At each center mark, cut a 2-½” hole through the wall. The intake vent pipe should
extend out 1” to 6” from the finished wall surface. The exhaust pipe must extend 12”
past the intake; 13” to a maximum of 18” from the finished wall surface. Seal around the
vent pipe at the wall with caulking. Flashing may be used as needed.
Alternative vent kits are available that provide a clean, finished appearance. Use only
approved termination kits.
See the “Venting” section of the “Installation Instructions” in the Use and Care Manual for
details and alternatives to venting locations and using other termination options.
Step 2. Install Vent Pipe
The vent system for this water heater is
designed for use with solid core, Schedule
40 PVC pipe only. DO NOT use foam/
cell core PVC pipe. Other alternative pipe
material is listed in the “Venting” section of
the Use and Care manual. DO NOT use
any other material not listed in the Use and
Care “Installation Instructions.”
Both the exhaust and air intake vents
MUST be run to the outside. This appliance cannot
use indoor air for operation as improper operation
or failure can occur.
You can use up to 60 ft of 2” PVC and 150 ft of 3”
PVC, DO NOT mix vent sizes. The exhaust and air
intake must be close to the same length each and
they must go out the same side of the building.
Measure, cut, and dry fit the venting together before
gluing the fittings. Start at the water heater with the
exhaust and work your way to the termination going
outdoors. Complete the air intake as well. Once
all the pieces are cut, mark and label each piece so you know
which order to reassemble the venting.
Disassemble the dry-fit venting, clean each fitting and piece.
Starting at the water heater, carefully glue the pipe and fittings
together. Ensure each joint is sealed and tight. Use plumbing strap
or pipe support clamps to secure any long vent runs.
Once complete, reinspect the venting, ensure all the connections are
solid and verify that local codes and all requirements outlined in the Use
and Care Manual have been followed.
See the “Venting” section of the “Installation Instructions” in the Use and
Care Manual for the requirements for venting.
Draining the Water heater
When a building is without electricity, water, or gas, the water heater should be drained to prevent freezing in winter conditions. Shut off gas,
water, and power to the water heater. Connect a hose to the drain valve on the hot water side and open the valve. Remove the cold water inlet
filter to allow air into the system so it will drain.
See the “Freeze Protection” section of the “Installation Instructions” in the Use and Care Manual for details.
NOTICE: IF THE BUILDING IS TO REMAIN UNOCCUPIED FOR AN EXTENDED PERIOD OF TIME, IT IS RECOMMENDED THAT THE
TANKLESS WATER HEATER BE DRAINED TO PREVENT POSSIBLE DAMAGE DUE TO FREEZING CONDITIONS.
Step 6. Install Condensate
Drain
Slide a ½” inner diameter drain hose
over the fitting at the bottom of the water
heater. Secure the hose with a clamp.
Run this drain hose to an open drain. DO
NOT create a trap in the hose, and DO
NOT pinch or collapse the hose.
Leave an air gap between the end of the
hose and the drain. The condensate water
must be allowed to run free into the drain.
See the “Condensate” section of the “Installation Instructions” in
the Use and Care Manual for details.
NOTICE: REMOVE THE FACTORY SHIPPING CAP FROM
THE DRAIN CONNECTION, INSTALL A DRAIN LINE AND RUN
TO A SUITABLE DRAIN. THIS WATER HEATER WILL NOT
FUNCTION PROPERLY AND ERROR OUT WITH A CODE 29
IF THIS STEP IS NOT COMPLETED PROPERLY.
