GAS PRESSURE REGULATOR
NOTE:
The tankless water heaters TE125X, TE125H, TE80X and TE80H are supplied
with a gas pressure regulator that must be installed on the heater before attaching the
gas supply line. (See Fig.8)
Failure to install the gas regulator as illustrated will violate the CSA certification of the
unit. The regulator supplied with the heater is pre-set to the correct pressure for the gas
shown on the rating plate to the correct pressure
.
The pressure regulator provided with the heater is adjusted to deliver the proper gas (LP
or NG) pressure (as indicated on the rating plate).

Gas Pressure Regulator
Note
: An embossed arrow on the rear of the Gas Pressure Regulator indicates the flow
direction of the fuel. Always install the regulator with the arrow pointing in the direction
of the heater inlet.
WATER CONNECTIONS
Install a manual in-line water control valve on the inlet water line. Although water piping
throughout your structure may be other than copper, we recommend that copper piping
be used for at least three feet before and after the water heater. Be sure to use a
dielectric union to prevent electrolysis. If the water heater is installed in a closed water
system, means should be provided to control thermal expansion such the installation of
a water expansion tank. Contact the water supplier, a certified plumber or the local
plumbing inspector on how to handle this situation
.
Be sure to remove the plastic pipe stops (used for shipping purposes only) at the water
connections before connecting the water pipes to the heater. Connect the cold water
pipe to the right water-in connection, as you face the heater. Connect the hot water pipe
to the left water-out connection, as you face the heater.
NOTE: Models TE80P and TE125P are supplied with a gas pressure regulator that is
built in the gas/water unit.
