GAS SUPPLY AND GAS PIPE SIZING Check that the type of gas matches the rating
plate located on the cover of your water heater.
The minimum and maximum inlet gas pressures
are:
Natural Gas Min. 5” WC - Max. 10.5” WC
Propane Gas Min. 11” WC - Max. 14” WC
Gas pressure below this specified range for the
T-K2 and/or insufficient gas volume will adversely
affect performance. Inlet gas pressure must not
exceed the above maximum values; gas pressure
above the specified range will cause dangerous
operating conditions and damage to the unit. Until
testing of the main gas line supply pressure is
completed, ensure the gas line to the T-K2 is
disconnected to avoid any damage to the water
heater.
Size the gas pipe appropriately to supply the
necessary volume of gas required for the T-K2
(185,000 BTUH) using ANSI233.1/NAPA 54 in
the USA or CAN/CSA B149.1 in Canada or local
codes. Install a manual gas shut-off valve
between the T-K2 and the gas supply line.
When the gas connections are completed, it is
necessary to perform a gas leak test either by
applying soapy water to all gas fittings and
observing for bubbles or by using a gas leak
detection device. Always purge the gas line of
any debris before connecting to the heater gas
inlet.

FOR YOUR SAFETY, READ
BEFORE OPERATING:
A. This water heater does not have a pilot. It
is equipped with an electronic ignition
device that automatically lights the burner.
Do not try to light the burner manually;
B. BEFORE OPERATING, check all around
the water heater area for gas leaks. Be
sure to check next to the floor as some
gases are heavier than air and will settle
on the floor;
C. Use only your hand to turn the gas valve
knob. Never use tools. If the knob will not
turn by hand, do not attempt to repair it.
Call a qualified service technician. Force
or attempted repair may result in a fire or
explosion.
D. WARNING: Conversion of this unit from
natural gas to propane or propane to
natural gas cannot be done in the field.
Contact your local distributor to get the
correct unit for your gas type. Conversion
