IF THE INFORMATIONIN THESE INSTRUCTIONS ARE NOT FOLLOWEDEXACTLY, A FIRE OR
EXPLOSION MAY RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.
-
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance;
WHAT TO DO IF YOU SMELL GAS:
-
Do not try to light any appliance;
-
Do not touch any electrical switch; do not use any phone in your building;
-
Immediately call your gas supplier from a neighbor's phone;
-
Follow the gas supplier's instructions;
-
If you cannot reach your gas supplier; call the fire department;
-
Installation and service must be performed by a qualified installer, service agency or the gas supplier.
Water temperature over 125 degrees F. can cause severe burns instantly,
or death from scalds. Children, disabled, and elderly are at highest risk
of being scalded. See instruction manual before setting temperature at
water heater. Feel water before bathing or showering! Temperature
limiting valves are available.
LOCATION
Choose a location for your water heater centralized to the piping system, along with consideration to vent pipe length. As the length of
vent pipe increases the firing rate of the appliance decreases. You must also locate the Voyager where it will not be exposed to freez-
ing temperatures. Additionally, you will need to place the water heater so that the controls, drain, inlet/outlet, and gas valve are easily
accessed. This appliance must not be installed outdoors, as it is certified as an indoor appliance, and must be kept vertical and on a
level surface. Also, care must be exercised when choosing the location of this appliance; where leakage from the relief valve, leakage
from related piping, or leakage from the tank or connections, will not result in damage to the surrounding areas or to the lower floors of
the building. A water heater should always be located in a area with a floor drain or installed in a drain pan suitable for water
heaters. Proper clearance must be provided around the Voyager as follows: Sides, bottom, top, and back are 0" (zero clearance).
Front of the appliance needs 24" service clearance minimum. This front service may be achieved by a non-rated or combustible door
or access panel; providing the 24" service clearance is achieved when the door is opened or panel is removed. Under no circum-
stances, shall National Combustion Co. Inc. be held liable for any such water damage whatsoever. This water heater must
not be located near flammable liquids such as gasoline, adhesives, solvents, paint thinners, butane, liquefied propane, etc.;
as the controls of this appliance could ignite those vapors, causing an explosion.
TEMPERATURE AND PRESSURE RELIEF VALVE
A temperature and pressure relief valve is installed into the marked port (upper right), we recommend a WATTS 100XL-4 valve or
equivalent for 100,000 BTU models or below input, 40XL5 valve or equivalent for 130,000 BTU models or above input, meeting the
requirements for relief valves for hot water heaters as per ANSI Z21.22B-1984 by a nationally recognized lab that maintains a periodic
inspection of production of such listed safety device. The pressure rating of the valve must not exceed the listed working pressure of
this appliance, and must be rated to the proper BTU/hr capacity of the water heater. Do not, under any circumstances, thread a cap
or plug into the relief valve! Explosion, serious injury or death may result! Relief valve piping must be directed to the floor or to
an open drain, but not connected directly. There must be a 6" space between the outlet of relief valve piping and drain or floor. Do not
hook up to drain system directly without an air space. The relief valve must be periodically checked for proper operation.
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 expansion tank must be suitable for hot potable water.
