Use and Care Manual
LP-436 Rev. 5.2.18
13
NEVER use an open ame to test for gas leaks. A re or explosion
could occur resulting in property damage, severe personal injury, or
death.
NEVER operate the water heater unless it is completely full of water.
Failure to follow this instruction can result in premature failure of the
water heater. Such failure IS NOT covered by warranty.
DO NOT attempt to use this water heater with any gas other than the
type shown on the water heater rating plate. Failure to follow this
instruction can result in property damage, personal injury, or death.
3. Filling the Water Heater
Check that all the water piping connections have been made. To ll
the water heater:
1. Make sure that the water heater drain valve is closed by
turning the knob clockwise.
2. Open the cold water supply manual shut-o valve. This
valve must remain open as long as the water heater is in use.
NEVER operate the water heater with the cold water supply
manual shut-o valve closed.
F. Gas Connections
Figure 13 - Typical Installation
The gas piping must be installed as indicated in Figure 13. For the
correct size of piping for this water heater, consult the National Fuel
Gas Code, ANSI Z223.1 / NFPA 54 in the United States, or CAN/CSA
B149.1, National Gas and Propane Installation Code in Canada. Only
new piping with cleanly cut threads may be used, together with a
suitable sealing compound that is approved for natural and propane
gases. It is mandatory that a readily accessible manual shut-o valve
be installed in the gas supply line. The gas supply manual shut-o
valve must be close to the water heater. A drip leg (sediment trap)
must be installed in the gas line ahead of the main gas valve to prevent
dirt from entering it. A union must be installed between the main gas
valve and the gas supply manual shut-o valve for easy maintenance
of the water heater.
2. Pressure Build-Up in a Water System
When the water heater operates, the heated water expands creating
a pressure build-up. This is a natural function and is one of the
reasons for installing a temperature and pressure relief valve. If the
cold water supply line has a built-in water meter, check valve, or
pressure-reducing valve, a suitable expansion tank must be installed
to prevent pressure build-up or water hammer eect. Otherwise, the
warranty is void. See Figure 13. An indication of pressure build-up is
frequent relief valve discharge. If the relief valve discharges water on
a continuous basis, it may indicate a malfunction of the relief valve
and a qualied service technician must be called to have the system
checked and the problem corrected.
RE-INSPECTION OF T&P RELIEF VALVES: T&P valves should be
inspected AT LEAST ONCE EVERY THREE YEARS, and replaced if
necessary, by a licensed plumbing contractor or qualied service
technician to ensure that the product has not been aected
by corrosive water conditions and to ensure that the valve and
discharge line have not been altered or tampered with illegally.
Certain naturally occuring conditions may corrode the valve and
its components over time, rendering the valve inoperative. Such
conditions can only be detected if the valve and its components
are physically removed and inspected. Do not attempt to
conduct an inspection on your own. Contact your plumbing
contractor for a re-inspection to assure continued safety.
FAILURE TO RE-INSPECT THE T&P VALVE AS DIRECTED COULD
RESULT IN UNSAFE TEMPERATURE AND/OR PRESSURE BUILD-
UP WHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUS
PERSONAL INJURY, OR DEATH.
3. To make sure the water heater is completely full of water, open
hot water faucets to let the air out of the water heater and
plumbing system. Leave the faucets open until a constant ow
of water is obtained.
4. Check all of the plumbing connections to make sure there are
no leaks.
