WARNING
!
This Quick Start Guide DOES NOT replace the Use and Care Manual. Read and
comprehend the Use and Care Manual before installing this product.
Step 1 - Before Installing
This product must only be installed by a qualied installer / service technician.
The manufacturer will not be held liable for any damages resulting from im-
proper installation.
Follow all local codes as well as the most recent edition of the latest version of
the National Electrical Code, NFPA No. 70.
When applicable, the installation must conform with Manufactured Home
Construction and Safety Standards, Title 24 CFR, Part 3280 and/or CAN/CSA
Z240 MH Series Mobile Homes.
Failure to follow these instructions before installation could result in property
damage, personal injury or death.
Step 2 - Installing
NOTICE
Any claims for damage or shortage in shipment must be led immediately
against the transportation company by the consignee.
A. Unpacking
B. Location Requirements
Choose a location for the water heater as centralized to the piping and electrical
system as possible, and where domestic water piping will not be exposed to
freezing temperatures. All piping should be insulated. Additionally, place the
water heater so that the drain, controls, and inlets/outlets are easily accessible.
C. Wall Mounting
The mounting surface must be solid and secure. Do not install the unit above
electrical boxes or junctions. Ensure the unit is level. Mount the unit to the wall
with four (4) screws of at least one (1) inch in length.
NOTICE
Use screws suitable for the wall material and the weight of the water heater.
Failure to do so could result in property damages and damage to the water
heater. Such damages ARE NOT covered by product warranty.
The appliance must be mounted horizontally, with water inlets and outlets at
the bottom. See Figure 3.
WARNING
!
This water heater must be installed upright in the vertical position as described
in this manual. DO NOT attempt to install this water heater in any other orien-
tation. Doing so will result in improper water heater operation and property
damage, and could result in serious personal injury or death.

OR ON ITS SIDE
Step 3 - Plumbing
It is mandatory that all plumbing be done in accordance with federal, local, and
state plumbing codes and practices.
A temperature and pressure relief valve (T&P) is not required for most installa-
tions, as UL Standard 499 does NOT require that a pressure relief valve be used.
However, a T&P valve may be required to meet installation codes in your area.
NOTE: It is highly recommended by the manufacturer to install water leak de-
tection devices and automatic shuto valves in any water heater installation
where a leakage of water could result in property damages.

Step 4 - Electrical Connection
The voltage requirement and dedicated wattage load for the heater is specied
on the water heater rating label. Consult your local power company to deter-
mine if your electrical service is adequate for the additional load of the heater.
For power supply connection use 8/2 AWG wires or larger, suitable for at least
194
o
F (90
o
C).
Make secure, appropriate wiring connections to the water heater per the Nation-
al Electric Code.
Table 2 - Technical Specications - *Wattage based on maximum voltage.
Connect the water
inlet line to the
entry point of the
heater (right side
inlet), and connect
the outlet line to
the water outlet.
Use a line that can
withstand pres-
sure up to 145 psi.
Using any other
type of line will
cause damage. In-
stall unions on the
hot and cold water
connections to
easily disconnect
the water heater
for servicing.
