WATER HEATER PLACEMENT
Additional Safety Instructions
Carefully choose the location for the new heater as
placement is a very important consideration for the
safety of the occupants in the building and for the most
economical use of the appliance.
Whether replacing an old water heater or putting the
water heater in a new location, consider the following
critical points:
The location selected should be as close to the
vent termination point as possible, and centered
within the water piping system for best hot water
delivery. All water heaters can leak. Do not install
without adequate drainage provisions where wa-
ter flow can cause property damage.
If vented through an outside wall or through the roof
using 4" vent piping the total vent run cannot ex-
ceed 30 feet with one 90 elbow. If more elbows are
required the venting distance must be reduced 5
feet for every 90 elbow.

Vent piping cannot slope upward and horizontal
runs require 1/4'' per foot rise. All horizontal runs
require adequate support at 3 1/2 foot intervals and
vertical runs supported at 5 feet intervals.
Condensation may be created at times as the com-
bustion gases exit the vent cap. Discoloration of sur-
faces in proximity to the vent cap may occur.
CAUTION
!
!
Before commencing the Installation
Check that it is in accordance with relevant building
and mechanical codes, as well as any local or state
or federal regulations.
For other than direct vent appliance, the appliance
must be located as close as possible to a chimney
or gas vent.
The appliance should be located in an area where
leakage of the tank or connections will not result
in damage to the area adjacent to the appliance
or to lower floors of the structure. When such
locations cannot be avoided, it is recommended
that a suitable drain pan be installed under the
appliance. The pan must not restrict combustion
air flow.
The minimum inlet gas pressure must be within
the value specified by the manufacturer and the
minimum value listed is only for the purpose of
input adjustment.
If a water heater is installed in closed water supply
system, such as one having a backflow preventer
in the cold water supply line and a thermal expan-
sion tank is required, contact the water supplier or
local plumbing inspector on how to control this
situation.
The Temperature and Pressure (T&P) relief valve
must be certified as meeting the requirement of the
Standard for Relief Valves and Automatic Gas Shut-
off Devices for Hot Water Supply Systems ANSI Z21.
22 /CAN1-4.4.The valve must be marked with a maxi-
mum set pressure not to exceed the marked hydro-
static working pressure of the water heater (150 psi)
and a discharge capacity not less than the water
heater input rate as marked on the rating plate.
For tube type water heaters, the relief valve must
be installed near the hot water outlet.
For tube type circulating water heaters, installed
only with a pressure relief valve, the separate
storage vessel must have a temperature and relief
valve installed. This relief valve shall comply with
the Standards for; "Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems".

1. Read the Safety guidelines in the beginning of this
manual.
The internal computer controlled regulator is pre-
set by the manufacturer and should not be adjusted
by user.
Maintain proper space around the unit for servicing.
Install the unit so that it can be connected or re-
moved easily.
The electrical connection requires a means for
switching off the power supply.
Avoid installing the unit in an area with high levels
of dust, sand, or debris. These particles may clog
the air vent or impair the function of the fan, leading
to improper combustion. Regular maintenance is
needed.
Do not install the unit where the exhaust vent is
pointing into any opening in a building or where the
noise may disturb neighbors.
