Bananza cannot be responsible for ensuring that all
appropriate safety measures are undertaken prior to
installation; this is entirely the responsibility of the
installer. It is essential that the contractor, the subcontractor, or the owner identifies the presence of
combustible materials, corrosive chemicals or
halogenated hydrocarbons* anywhere in the
premises.
* Halogenated Hydrocarbons are a family of chemical
compounds characterized by the presence of halogen
elements (fluorine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaning
agents, solvents, etc. If these compounds enter the air
supply of the burner, the life span of the heater components will be greatly reduced. An outside air supply must
be provided to the burners whenever the presence of
these compounds is suspected. Warranty will be invalid
if the heater is exposed to halogenated hydrocarbons.
2.3 National Standards and Applicable Codes
All equipment must be installed in accordance with
the latest revision of the applicable standards and
national codes. This refers also to the electric, gas
and venting installation. Note: Additional standards
for installations in public garages, aircraft hangars,
etc. may be applicable. See Page 7, Section 5.

Failure to follow these instructions can result in death, electric shock, injury or property damage.
The UHD[X][S] Series heaters are fully automatic
and operate from the external controls fitted on site.
The only user control at the heater is the Manual
Reset Limit Switch - See Page 28, Section 12.2.
See Page 40, Section 15.3 for manual reset limit
switch location inside control housing.
12.1 Heater Operation
When the heater has been switched on by the
thermostat installed on site, the main burner will
automatically turn on.
The burner control module will control the safe
ignition of the flame.
All heaters require a constant gas and electricity
supply which must not be interrupted during the
normal operation of this heater.
12.2 Common User Controls
12.2.1 Manual Reset Limit Switch
WARNING
Explosion Hazard
Do not make more than one attempt to
restart the heater if manual reset limit switch
locks out.
The vent or heat exchanger may be blocked.
The fault must be traced and repaired.
Failure to follow these instructions can
result in death, injury or property damage.
The limit thermostat is located inside the hinged
access door of the heater. See Page 40, Section
15.3. This control protects against excessive heat
build-up inside the burner compartment.

12.4.1 Simple Troubleshooting (Burner Faults)
If the burner fails to ignite for any reason, it will retry
for ignition (four trials total). After four unsuccessful
ignition trials, the control will put the heater into
lockout for one hour.
Lockout should not occur during normal operation of
the heater and indicates there is a fault condition
which must be corrected. There is an LED light on
the ignition control that flashes codes to assist in
fault correction. See Page 29, Figure 18 for LED
indication codes.
Figure 18: LED Diagnostic Codes
12.3 Lighting Instructions
12.3.1 To Turn On Heater
1. Ensure that the electrical and gas supplies to
the heater are on. Check that the on site
controls are "ON".
IMPORTANT: The thermostat setting must be above
the ambient temperature for the heater to operate.

2. The automatic firing sequence will begin as
described on Page 26, Figure 15. The heater
will now operate automatically under the control
of the on site controls.
12.3.2 To Turn Heater Off
Set the thermostat to the "OFF" position or lowest
setting. The burner will turn off immediately.
To restart, turn the thermostat on or above room
temperature.
12.4 Simple Troubleshooting
Some possible reasons for the heater not operating
are:
1. Gas supply not "ON".
2. Electricity supply not "ON".
3. The time and/or temperature controls are not
"ON".
4. A limit switch may have operated. This may be
caused by an interruption of the electrical
supply, failure of the distribution fan or vent or
heat exchanger blockage.
If a temperature limit switch persistently trips, there
is a fault which must be investigated by a contractor
qualified in the installation and service of gas-fired
heating equipment.
