INTRODUCTION
This manual provides information necessary
for the installation, operation, and maintenance
of the Model T-H1 appliance. This unit includes
a fan enabling sidewall (power) venting, an
advanced electronic ignition system and a
condensate neutralizer.
The model description is listed on the rating
plate which is attached to the front cover of the
appliance. Please read all installation
instructions completely before installing this
product. If you have any problems or
questions regarding this equipment, consult
with Takagi or its local representative.
Experiences have shown that most operating
problems are caused by improper installation.
The T-H1 Appliance is an instantaneous,
tankless appliance designed to supply endless
hot water to your entire household and/or
commercial facility utilizing total efficiency. The
principle behind the T-H1 Appliance is simple.
Once you open a hot water tap, water flows
through the T-H1 Appliance. Once a minimum
of 0.75 GPM is achieved, the flow sensor
automatically commands the computer to turn
on the fan, activate the electronic igniter and
open the gas valves. The computer monitors
water temperature, water flow rate and gas
flow to ensure that you get the right amount of
hot water at the correct hot water temperature.
After the burners are ignited, the “fire on” lamp
is lit. The computer will modulate the gas
supply valve and water flow. 0.75 gallons per
minute is required to turn the burners on; after
the burners are ignited, the flow rate can be
lowered to 0.6 gallons per minute to maintain
the appliance on. It is advisable to open further
the cold tap rather than decreasing the hot tap
to adjust the water temperature. As long as
you have water, gas and electricity, you will get
an endless flow of hot water. Open a hot water
tap to turn on your appliance. Close the tap to
turn off your appliance.
FOR YOUR SAFETY
PLEASE READ THIS MANUAL CAREFULLY
AND FOLLOW ALL DIRECTIONS.
1. Follow all local codes, or in the absence of
local codes, follow the most recent edition
of the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 in the USA or the
CAN/CSA B149.1 Natural Gas and
Propane Installation Code in Canada.
2. Properly ground the unit in accordance with
all local codes or in the absence of local
codes, with the National Electrical Codes,
ANSI/NFPA 70 in the USA or CSA
standard C22.1 Canada Electrical Code
Part 1 in Canada.
3. Carefully plan where you intend to install
your T-H1 Appliance. Ensure that your
appliance will have enough combustible air
and proper ventilation and locate your
appliance where water leakage will not do
damage to surrounding areas. If there is a
possibility of water damage, install a
suitable drain pan under the unit which will
not restrict combustible airflow.
4.
Check the rating plate for the correct gas
type, gas pressure, water pressure and
electrical rating. If this unit does not match
your requirements, do not install.
The installer is responsible for the correct
installation of your Flash T-H1 Appliance.
Installation and service must be performed
by a qualified installer (for example, a
licensed plumber or gas fitter) otherwise the
warranty by Takagi will be void.
