INSTALLATION
GENERAL
All gas appliances require careful and correct
installation to ensure safe and efficient
operation. This manual must be followed
exactly. Read the “For Your Safety” section at
the beginning of this manual.
1. The gas regulator is preset at the factory; it
is computer controlled and should not need
adjustment;
2. Maintain proper space for servicing. Install
the unit so that it can be connected or
removed easily;

for switching off the power supply;
4. If you will be installing the unit in a
contaminated area with a high level of dust,

please purchase the optional TK-TV07
direct vent conversion kit and convert the
T-H1 to a sealed combustion unit. The
warranty will not cover damage caused to
the unit due to installation in a
contaminated environment that has not be
converted using the TK-TV07.

air vent or reduce the functions of the
rotating fan and cause improper burning of
the gas. Regular maintenance is
recommended for these types of
environment.

vent is pointing into any opening in a
building or where the noise may disturb
your neighbors. Make sure the vent
termination is 4 feet from a doorway or
opening to prevent exhaust from entering.
