Tank MUST be full of water before power is turned
on. Heat exchanger coil WILL BE DAMAGED if ener-
gized even for a short time while the tank is dry. The
water heater’s warranty does not cover damage or
failure resulting from operation with an empty or par-
tially empty tank. (Reference is made to the limited
warranty for complete terms and conditions)
ELECTRICAL CONNECTION
The electrical connection for the AdvantagePlus is on the
left side of the combustion shroud. There is a 1/2" knock-
out location for electrical connection. All electrical wiring
must be performed by a qualified licensed electrician,
and in accordance with National Electrical Code, or to the
applicable local codes and standards. The electrical
requirements are for standard 120 volts, 60 Hz., 10 amp
service. It is recommended that an electrical disconnect
switch be placed near the water heater, and that the con-
nection to the AdvantagePlus be made using 3/8" extra-
flex, or 3/8" greenfield (or equivalent). This unit must be
wired with #14 AWG, and fused for no more than 15
amps.
It is of extreme importance that this unit be
properly grounded! Ground the water heater by con-
necting the green wire in the electrical access compart-
ment directly to the main building ground system. It is
very important that the building system ground is
inspected by a qualified electrician prior to making
this connection. Once all connections have been
made, the electrical access may be closed. It is very
important that the electrical power is not turned on until
gas and venting connections are completed and the tank
is full of water.
A green LED is provided on the main control board.
This LED must be illuminated when appliance is
turned on for proper operation. Failure to illuminate
means bad or missing ground or reverse polarity.
GAS CONNECTION
Gas supply shall not exceed a maximum inlet pressure of
14" water column (350 mm), 1/2 pound pressure (3.4
kPa), and a minimum of 7" water column (natural and
propane). The entire piping system, gas meter, and reg-
ulator must be sized properly to prevent a pressure drop
greater than 0.5" of water column as stated in the
National Fuel Gas Code. Gas pressure information is
listed on the rating plate. It is very important that you
are connected only to the type of gas noted on the
rating plate; "LP" or propane gas or "Nat" natural
gas or city gas. All gas connections must be approved
by the local gas supplier or utility in addition to the gov-
erning authority prior to turning the gas supply on. The
nipple provided for the inlet gas connection is 1/2", and it
is mandatory that a 3/4" to 1/2" reducing bushing (pro-
vided) is used, threaded into the branch of a 3/4" tee, and
a drip leg fabricated, as per the National Fuel Gas Code.
You must ensure that the entire gas line to the reduc-
ing bushing connection at the Advantage Plus is no
smaller than 3/4".
THE USE OF FLEXIBLE GAS CONNECTORS IS NOT RECOM-
MENDED. HOWEVER, IF USED, IT IS IMPERATIVE THAT THEYARE
SIZED CORRECTLY. FLEXIBLE GAS CONNECTORS MUST HAVE A
MINIMUM ID OF 3/4". A MINIMUM 3/4" ID MUST BE MAINTAINED
TO AVOID RESTRICTION OF GAS FLOW! NEVER REDUCE THE
GAS SUPPLY LINE BELOW 3/4"!
Once all the inspections have been performed, the piping
system must be leak tested. If the leak test pressure is
higher than the maximum permissible inlet pressure, you
must isolate the AdvantagePlus from the gas line before
testing. In order to do this, you must disconnect the
union and cap the inlet gas line. In the event the gas
valve is exposed to a pressure greater than 1/2 PSI, 14"
water column, the gas valve must be replaced.
Failure to follow all precautions could result in fire,
explosion or death! It is recommended that a soapy
solution be used to detect leaks. Bubbles will appear and
indicate a leak is present. The gas piping must be sized
for the proper flow and length of pipe to avoid unaccept-
able pressure drop. Both the gas meter and the gas reg-
ulator must be properly sized for the total gas load. If you
experience a pressure drop greater than 1" W.C., the
meter or regulator or gas line may be undersized or in
need of service. On the inlet side of the gas valve, there
is a 1/8" NPT plug. This plug can be removed to attach a
manometer. You can attach a meter to the incoming gas
drip leg by removing the cap and installing the meter. The
gas pressure must remain between 7" and 14" of water
column during stand-by and unit running heat cycle. If an
in-line regulator is used, it must be a minimum of 10 feet
from the AdvantagePlus. It is very important that the
gas line is properly purged by the gas supplier or
utility. Failure to properly purge the lines or improp-
er line sizing, will result in the failure of the
AdvantagePlus lighting off. The gas valve is a special
gas valve which has a Pressure Augmented Regulator
feature, as well as negative outlet pressure. This valve
must not be replaced with a conventional valve under any
circumstances. Make sure valve is in the “OFF” position
prior to turning gas supply on. As an additional safety
feature, this valve has a left hand thread on the outlet
end, and a special tamper resistant electrical connector.
Never use open flame to test for gas leaks, as
bodily injury or property damage could result.
DO NOT exceed input shown on water heater rating
plate.
