EXPANSION TANK
A potable hot water expansion tank may be required to offset the water expansion as the water is heated. In most city plumbing sys-
tems, the water meter has a no return or back flow device built into the system to prevent back flowing of water back into city mains.
Some require back flow preventers on all incoming water supplies. Under these circumstances, you will need a hot water expansion
tank listed for potable water use. The expansion tank should be located on the cold inlet piping close to the water heater.
The expan-
sion tank must be suitable for hot potable water.
DOMESTIC WATER CONNECTIONS
WARNING!!
NEVER USE DIELECTRIC UNIONS OR GALVANIZED STEEL FITTINGS ON ANY DOMESTIC WATER CONNECTIONS.
USE
ONLY COPPER OR BRASS FITTINGS. TEFLON THREAD SEALANT MUST BE USED ON ALL CONNECTIONS.
The domestic water connections must be installed in accordance to all local and national plumbing codes, or any applicable standard
which prevails. The inlet and outlet ports of the Voyager are 1" on 45 gallon models. On the 80 and 119 gallon models, the inlet and
outlet ports are 1 ½". On the cold inlet, (bottom left), install a 1" brass tee on 45 gallon models, or a 1 ½" tee on 80 and 119 gallon
models. On the run of the 1" brass tee, install with pipe sealant compound, a 1" brass drain cock or equivalent. Into the branch of the
1" or a 1 ½" brass tee, install a copper male adapter to match your copper plumbing system. For convenience, you may install a sweat
shut off valve and a union in the cold inlet piping to ease servicing in the future. If there is a back flow preventer, or any type of a no
return valve in the system, then you must install an additional tee here for a suitable potable hot water expansion tank. In the hot out-
let, (top left), install a suitable adapter to match the copper tubing of the plumbing system. A thermal trap or heat trap loop may be
installed here, to provide additional energy savings and prevent the thermal siphoning of domestic hot water. Refer to
pages 23 or 24
for typical installations. A domestic hot water tempering/anti-scald valve should be installed into hot water line to prevent the maximum
outlet water temperature from exceeding 119 degrees F. as per the national standard plumbing code, to prevent scald injury.
ELECTRICAL CONNECTION
The electrical connection for the Voyager is on the left side of the combustion shroud. There is a 1/2" knockout 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 rec-
ommended that an electrical disconnect switch be placed on a nearby wall, and that the connection to the Voyager 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 connecting the green wire in the electri-
cal access compartment, 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. The black wire is the hot lead and the white wire is the
neutral lead. Once all connections have been made the electrical access may be closed. It is very important that the electri-
cal power is not turned on at this time! A green LED is provided on the main control board. This LED must be luminated
when appliance is turned on for proper operation. Failure to luminate means bad or missing ground or reverse polarity.
GAS CONNECTION
Gas supply shall have a maximum inlet pressure of less than 14" water column (350 mm), 1/2 pound pressure (3.4 kPa), and a mini-
mum of 7" water column. The entire piping system, gas meter, and regulator must be sized properly to prevent pressure drop greater
than 0.5" as stated in the National Fuel Gas Code. This information is listed on the rating plate.
It is very important that you are
connected to the type of gas as noted on the rating plate. "LP" or liquefied petroleum, 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 governing authority, prior to turning the
gas supply on. The nipple provided is 1/2", and it is mandatory that a 3/4" to 1/2" reducing bushing (provided) 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 connection at the Voyager is no smaller than 3/4" . Once all the inspections have been performed, the piping must be leak test-
ed. If the leak test requirement is a higher test pressure than the maximum inlet pressure, you must isolate the Voyager from the gas
line. 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.
Never use an open flame (lit match, lighter) to check gas
connections.
