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-M1 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-M1 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-M1
(235,000 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-M1 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.
Pipe Sizing Example: This table below is for
Natural gas piping supply straight to the water
heater without any tabs to other gas appliances
Recommend Gas pipe size for
T-M1 Water Heater(Example for NG)
Distance from Gas Meter Pipe Size (inches)
0' - 20' 3/4"
20' - 70' 1"
70' – 200’ 1-1/4"
1. Turn off all electric power to the
water heater if service is to be
performed.
2. Turn the manual gas valve located
on the outside of the unit clockwise
3
to the off position.
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 done by
anyone other than the
manufacturer will void all warranty
.
