CAUTION
After completing all gas connections, check each gas connection and fitting for leaks. Use a soap and water solution or a commercial leak detector
fluid. NEVER USE MATCHES OR OPEN FLAME WHEN CHECKING FOR GAS LEAKS.
The water heater and its individual gas shut off valve must be disconnected from the gas supply piping system during any pressure testing or that
system at test pressures in excess of 1/2 psi (14" W.C.) or 3.5kPa.
The water heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the
gas supply piping system at test pressures equal to or less than 1/2 psi (l4"W.C.) or 3.5kPa.
If the gas valve is subjected to pressure exceeding 1/2 psi, the damage to the gas valve could result in an extremely
hazardous condition. If this has occurred, the gas valve must be replaced. Contact your dealer for service. It is
recommended that all service work be done by a qualified service agency
INSTALLATION SAFETY WARNING L.P. UNITS
Liquified petroleum (L.P.) gas is heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below
ground level will serve as pockets for accumulation of leaking gas. Before lighting, sniff at floor level.
IF YOU SMELL GAS, follow applicable instructions on Front Cover or Page 21, DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS
CORRECTED.
ANODES
This water heater is supplied with anode rods designed to extend tank life and reduce corrosion. Anodes emit a weak flow of electrical current
through the water to protect the tank. When present in "highly active" water, a "rotten egg" odor may be produced from the gases from the anodes,
mixing with the water. This is not the fault of the water heater. Chlorination of the water supply system should minimize this condition. (Consult
your telephone directory for local water treatment specialists).
REMOVAL OF AN ANODE ROD WILL VOID THE WARRANTY.
MULTIPLE HEATER INSTALLATION
INSTALLATION DIAGRAMS INSTALLATIONS WHERE HEATERS ARE MANIFOLDED.
All heaters should have approximately the same input rate. To manifold a high input heater with a low input heater will result in the lower input
heater running excessively. It is preferable for all heaters to be the same model.
All heaters must be evenly spaced to provide identical number of turns, length and size of pipes in each manifold. This is absolutely necessary to
insure a balanced condition to all heaters in the installation.
NEVER OPERATE AN EMPTY OR PARTIALLY FILLED WATER HEATER
DISCHARGE OF PURGED GASES
When removing purged gases from a piping system, care should be taken to not create hazardous condition, such as discharging the gases into a
confined area or in an area which contains an ignition source.
VENT PIPE SYSTEM
The water heater must be connected to the chimney. They vent pipe from the heater to the chimney (vent connector) must be no less than the
diameter of the drafthood outlet on the heater and should slope upward to the chimney at least 1/4 inch per linear foot.
Due to great variances in installations, unforeseeable by the manufacturer of the water heater, increased size vent connectors and pipes may be
necessary for proper venting.
Consult your local utility. They willl aid you in determining the proper venting for your heater from the vent tables in the american National Stand-
ard Z223.I (NFPA 54) “National Fuel Gas Code”.
There are various types of vent dampers currently available. Some of these vent dampers are certified by the Canadian Standard Association Labora-
tories. The certifications apply to the vent damper device only and do not mean they are certified for use on this water heater. The use of these
devices is not permitted by the manufacturer of this water heater.
NOTE: If the equipment room is located against an
outside wall and the air openings communicate directly
with the outdoors, each opening shall have a free area
of not less than one square inch per 4,000 BTU per
hour of the total input rating of all equipment in the
enclosure.

MECHANICAL EXHAUSTING AND FIREPLACES
the operation of air- moving devices such as exhaust
fans, ventilation system, clothes dryers fireplaces, etc.
can affect the proper operation of gas utilization
equipment.
Consequently, special attention must be given to
conditions these devices may create to avoid
unsatisfactory operation of the equipment.

IMPORTANT NOTICE
This water heater may be installed as a replacement with venting that met the existing codes at the time of the
installation of the original water heater.
This water heater uses a non-direct, single-pipe vent system to remove exhaust gases created by the burning of fossil fuels. Air for combustion is
taken from the immediate water heater location or is ducted in from the outside (see “Combustion Air Supply and Ventilation”).
This water heater must be properly vented for the removal of exhaust gases to the outside atmosphere. Correct installation of the vent pipes
system is mandatory for the proper and efficient operation of this water heater and is an important factor in the life of the unit.
U.L. approved fuel gas and carbon monoxide (CO) detectors are recommended in all applications and should be installed using the manufacturer´s
instructions and local codes, rules, or regulations.
Important: If you lack the necessary skills required to properly install this venting system, you should not proceed,
but get help from a qualified service technician.
