InstallaƟon of Gas Supply
MUST DO
• Check the type of gas and the gas inlet pressure
before connecng the water heater. If the water
heater is not of the gas type that the building is
supplied with, DO NOT connect the water heater.
Contact the dealer for the proper unit to match the
gas type.
• Check the gas supply pressure immediately up‐
stream at a locaon provided by the gas company.
Supplied gas pressure must be within the limits
shown in the Specificaons secon with all gas ap‐
pliances operang.
• Before placing the appliance in operaon all joints
including the heater must be checked for gas ght‐
ness by means of leak detector soluon, soap and
water, or an equivalent nonflammable soluon, as
applicable. (Since some leak test soluons, includ‐
ing soap and water, may cause corrosion or stress
cracking, the piping shall be rinsed with water aer
tesng, unless it has been determined that the leak
test soluon is non‐corrosive.)
• Use approved connectors to connect the unit to
the gas line. Purge the gas line of any debris before
connecon to the water heater.
• Any compound used on the threaded joint of the
gas piping shall be a type which resists the acon of
liquefied petroleum gas (propane / LPG).
• The gas supply line shall be gas ght, sized, and so
installed as to provide a supply of gas sufficient to
meet the maximum demand of the heater and all
other gas consuming appliances at the locaon
without loss of pressure.
WARNING
1. If you are not knowledgeable or qualified to
install gas lines or connecons, then contact a
licensed professional to install the gas supply.
2. Turn off 120v power supply.
3. Turn off the gas.
4. Gas is flammable. Do not smoke or provide other
ignion sources while working with gas.
5. Do not turn on the water heater or gas unl all
fumes are gone.
ConnecƟng Electricity
Do not rely on the gas or water piping to ground the
water heater. A screw is provided in the juncon box
for the grounding connecon.
The water heater requires 120 VAC, 60 Hz power from
a properly grounded circuit.
If using the 5 foot long power cord, plug it into a
standard 3 prong 120 VAC, 60 Hz properly grounded
wall outlet.
On outdoor models, a disconnect switch must be
provided and installed for the incoming 120 VAC
power. It should be a type that is suitable for outdoor
use. Check the Naonal Electrical Code, ANSI/NFPA
70 and your local codes for a proper switch type to
use in your area.
The wiring diagram is located on the Technical Sheet
aached to the inside of the front cover.
WARNING
Do not use an extension cord or an adapter plug with
this appliance.
The water heater must be electrically grounded in
accordance with local codes and ordinances or, in the
absence of local codes, in accordance with the
Naonal Electrical Code, ANSI/NFPA No. 70.
Indoor water heaters are equipped with a three‐
prong (grounding) plug for your protecon against
shock hazard and should be plugged directly into a
properly grounded three‐prong receptacle. Do not
cut or remove the grounding terminal from this plug.
