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 6 ft. long. Install the units 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.

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.

Using the incorrect voltage 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.

Precautions on Vent Pipe Replacement

•Only use vent materials that are specified in this Installation Manual for use on this appliance. Refer

to the "Vent Pipe Installation" section for details. If PVC, CPVC, or Category IV listed pipe is already

installed, check for punctures, cracks, or blockages and consult with the vent pipe manufacturer

before reusing.

Improper venting may result in fires, property damage or exposure to Carbon Monoxide.

Snow Precaution

•If this product will be installed in an area where snow is known to accumulate, protect the vent

termination from blockage by snow drifts or damage from snow falling off of roofs.

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.

•Locate the vent terminal so that there are no obstacles around the termination and so that ex-

haust 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

recreational vehicle or on a boat.

•The water heater is designed for indoor installation only. Never install it

outdoors or in a bathroom, it may be damaged or a fire may be caused.

•Consult with the customer concerning the location of installation.

• Install the water heater in an area that allows for the proper clearances

to combustible and noncombustible construction. Consult the rating

plate on the appliance for proper clearances.

•Do not install the water heater in a place where it may be threatened by

falling objects, such as under shelves.

• The water heater must be installed in a place where supply and exhaust

pipes can be installed as directed.

•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.

Prohibited

DANGER

WARNING

CAUTION
