Quick Connect Multi System Installation
• The Quick Connect Multi System allows the installation of two units together utilizing only the Quick
Connect Cord.
Typical Plumbing
The Quick Connect Cord is 2m (6'). long. Install the units 152 - 457mm (6-18") apart from each
other to ensure the cord will be able to reach between the units. (See Typical Plumbing diagram).
(If the distance between the two units is too great, not only will the cord not be able to reach,
but the water temperature may also become unstable because of the difference in pipe length
between the two units).
* When connecting two units, use only
a single remote controller.
Note: Connect the remote
controller to only one
of the units.
System Diagram
•Insulate the hot water piping to prevent heat loss. Insulate and apply heating materials to the cold
water supply piping to prevent heat loss and freezing of pipes when exposed to excessively cold
temperatures.
Union
Make this distance as short
as possible.
* The hot water temperature
will become unstable as the
pipe length increases.

Leave enough clearance around the plumbing to

bends to the piping to ensure that this clearance
is available.
Size the piping to allow for the maximum
flow rates of the units.

4. Before Installation
Checkup
• Check the fixing brackets and vent pipe yearly for damage or wear. Replace if necessary.
DANGER
Do Not Use Equipment for Purposes Other Than Those Specified
•Do not use for other than increasing the temperature of the water supply, as unexpected accidents
may occur as a result.
Check Water Supply Quality
•If the water supply is in excess of 12 grains per gallon (200 mg/L) of hardness, acidic or otherwise
impure, treat the water with approved methods in order to ensure full warranty coverage.
WARNING
CAUTION
Check the Gas
•Check that the rating plate indicates the
correct type of gas.
•Check that the gas supply line is sized for
199,900 Btuh for this unit.
Check the Power
•The power supply required is 120VAC, at 60Hz.
May result in fire or electric shock.
Use Extreme Caution if Using With a Solar Pre-Heater
• Using this unit with a solar pre-heater can lead to unpredictable output temperatures and
possibly scalding. If absolutely necessary, use mixing valves to ensure output temperatures do
not get to scalding levels. Do not use a solar pre-heater with the quick-connect multi-system.

5. Choosing Installation Site
* Locate the appliance in an area where leakage from the unit or connections will not result in damage
to the area adjacent to the appliance or to the lower floors of the structure. When such locations
cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed
under the appliance. The pan must not restrict combustion air flow.
• Install the exhaust vent so that there are no obstacles around the termination and so that
exhaust can't accumulate. Do not enclose the termination with corrugated metal or other
materials.
•Avoid places where fires are common, such as those where gasoline,
benzene and adhesives are handled, or places in which corrosive gases
(ammonia, chlorine, sulfur, ethylene compounds, acids) are present.
Using the incorrect voltage may result in fire or cracking.
•Avoid installation in places where dust or debris will accumulate.
Dust may block the air-supply opening, causing the performance of the
device fan to drop and incomplete combustion to occur as a result.
•Avoid installation in places where special chemical agents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
• Carbon Monoxide Poisoning Hazard. Do not install this water heater in a
mobile home, recreation vehicle or on a boat.
Prohibited
DANGER
WARNING

6
• Install in a location where the exhaust gas flow will not be affected by fans or range hoods.
•Take care that noise and exhaust gas will not affect neighbors. Avoid installation on common
walls as the unit will make some operational noises while it is running.
•Before installing, make sure that the vent termination (or the vent
cap in an outdoor installation) will have the proper clearances
according to the National Fuel Gas Code (ANSI Z223.1).
Be sure to do
Prohibited
Prohibited
CAUTION
•Consult with the customer concerning the location of installation.
• Do not install the water heater where the exhaust will blow on outer walls or material not resistant
to heat. Also consider the surrounding trees and animals.
The heat and moisture from the water heater may cause discoloration of walls and resinous
materials, or corrosion of aluminum materials.
•Install the water heater in a location where it is free from obstacles
and stagnant air.
•Do not install the water heater near staircases or emergency exits.
• Do not locate the vent termination directed towards a window or any
other structure which has glass or wired glass facing the termination.
• Avoid installation where the unit will be exposed to excessive winds.
[For outdoor installation only]
[For indoor installation only]
•Avoid installation above gas ranges or stoves.
• Avoid installation between the kitchen fan and stove.
If oily fumes or a large amount of steam are present in the
installation location, take measures to prevent the fumes and
steam from entering in the equipment.
•Make sure that the location allows installation of the exhaust
vent as specified.
•For outdoor installation, use the outdoor vent cap (#VC-4C only).
If it is necessary to vent above the roof line in an outdoor
installation, use high temperature sealant around the flue collar
for rain protection.
State of California: The water heater must be braced, anchored or strapped to avoid moving during an
earthquake. Contact local utilities for code requirements in your area or call: 1-866-766-7489 and request
instructions.
The Commonwealth of Massachusetts: The water heater can be used for hot water only and not in a
combination of domestic and space heating.

4. Drill holes for the remaining four screws.
5. Hang the unit again by the first screw, and then
insert and tighten the remaining four screws.
6. Take waterproofing measures so that water does
not enter the building from screws mounting the
device.
•Make sure the unit is installed securely so that it will
not fall or move due to vibrations or earthquakes.

1. Drill a single screw hole, making sure to hit a stud.
2. Insert and tighten the screw and hang the unit by
the upper wall mounting bracket.
3. Determine the positions for the remaining four screws
(two for the top bracket and two for the bottom), and
remove the unit.
• The weight of the device will be applied to the wall. If the strength of the wall is not suffi-
cient, reinforcement must be done to prevent the transfer of vibration.
•Do not drop or apply unnecessary force to the device when installing. Internal parts may
be damaged and may become highly dangerous.
• Install the unit on a vertical wall and ensure that it is level.

CAUTION
Be sure to do
•If this water heater is being installed at an elevation of
610m (2,000') or higher, disconnect the connector la-
beled "High Elevation Disconnect" as illustrated on the
right. This connector is located inside the unit.

DISCONNECT
•Disconnect power to the water heater before discon-
necting this connector. Failure to perform this step will
result in a "73" code displayed on the remote controller
and a cease in operation. If this occurs, disconnect,
then reconnect power to the water heater to reset the
system.
