GAS S SIZING
Check that the type of gas matches the rating
plate located on the cover of your appliance.
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-H1 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-H1 is
disconnected to avoid any damage to the
appliance.
Size the gas pipe appropriately to supply the
necessary volume of gas required for the T-H1
(NG 199,000 BTU/H; LPG 190,000 BTU/H) 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-H1 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
appliance gas inlet.

1. Turn off all electric power to the
appliance 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 appliance 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 appliance 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.

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
