SECTION 1: HEATER SAFETY
SECTION 1: HEATER SAFETY
Your Safety is Important to Us!
This symbol is used throughout the
manual to notify you of possible fire,
electrical or burn hazards. Please pay
special attention when reading and
following the warnings in these
sections.
Installation, service and annual inspection of heater must
be done by a contractor qualified in the installation and
service of gas-fired heating equipment.
Read this manual carefully before installation, operation or

SECTION 2: INSTALLER RESPONSIBILITY
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• To install the heater, as well as the gas and
electrical supplies, in accordance with applicable
specifications and codes. Bananza recommends
the installer contact a local Building Inspector or
Fire Marshal for guidance.
• To use the information given in a layout drawing
and in the manual together with the cited codes
and regulations to perform the installation.
• To install the heater in accordance with the
clearances to combustibles.
• To furnish all needed materials not furnished as
standard equipment.
• To plan location of supports.
• To provide access on all sides for burner servicing
and removal.
• To provide the owner with a copy of this
Installation, Operation and Service Manual.
• To never use heater as a support for a ladder or
other access equipment and never hang or
suspend anything from heater.
• To ensure there is adequate air circulation around
the heater and to supply air for combustion,
ventilation and distribution in accordance with
local codes.
• To safely and adequately install heater using
materials with a minimal working load of 75 lbs
(33 kg).
• To ensure the heater is placed in an approved
application.
2.1 Wall Tag
A laminated wall tag is available for the heater as
a permanent reminder of the safety instructions and
the importance of the required clearances to
combustibles. Please contact Bananza or your
BANANZA® independent distributor to obtain the wall
tag. Affix the tag by peeling
off the backing of the adhesive strips on the rear
surface and position the tag on a wall near the
heater (e.g. thermostat or BANANZA® Controller).
A copy of the wall tag (P/N 91037921) is illustrated on
the back cover. For an immediate solution, you may
affix this copy on the wall near the heater.
Know your model number and installed configuration.
Model number and installed configuration are found on
the burner and in the Installation, Operation and
Service Manual. See Page 5, Figure 3 through Page
8, Figure 12. Write the proper clearance dimensions in
permanent ink according to your model number and
configuration in the open spaces on the tag.
2.2 Corrosive Chemicals
CAUTION
Product Damage Hazard
Do not use heater in area containing
corrosive chemicals.
Refer to appropriate Material Safety Data
Sheets (MSDS).
Failure to follow these instructions can result
in product damage.
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 appliances 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.

BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 Required Clearances to Combustibles
Clearances are the required distances that
combustible objects must be away from the heater to
prevent serious fire hazards. Combustibles are
materials that may catch on fire and include common
items such as wood, paper, rubber, fabric, etc.
Maintain clearances to combustibles at all times
for safety.
Clearances for all heater models are located on the
burner of the heater and on Page 5, Figure 3 through
Page 8, Figure 12 in this manual. Check the
clearances on each burner for the model heater
being installed to make sure the product is suitable
for your application and the clearances are
maintained. Read and follow the safety guidelines
below:
• Keep gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors away from this heater or any other
appliance.
• The stated clearances to combustibles represents
a surface temperature of 90° F (32° C) above
room temperature. Building materials with a low
heat tolerance (such as plastics, vinyl siding,
canvas, tri-ply, etc) may be subject to degradation
at lower temperatures. It is the installer’s
responsibility to assure that adjacent materials
are protected from degradation.
• Maintain clearances from heat sensitive
equipment and workstations.
• Maintain clearances from vehicles parked below
the heater.
• Maintain clearances from swinging and overhead
doors, overhead cranes, vehicle lifts, partitions,
storage racks, hoists, building construction, etc.
• In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to maintain
required clearances from the heater to the
combustibles. Signs must be posted adjacent to
the heater thermostat. In the absence of a
thermostat, signs must be posted in a
conspicuous location.
• Consult local Fire Marshal, Fire Insurance Carrier
or other authorities for approval of proposed
installation when there is a possibility of exposure
to combustible airborne materials or vapors.
• Hang heater in accordance to the minimum
suspension requirements on Page 14, Figure 14.
4
WARNING
Fire Hazard
Keep all flammable objects, liquids and
vapors the minimum required clearances to
combustibles away from heater.
Some objects will catch fire or explode when
placed close to heater.
Failure to follow these instructions can result
in death, injury or property damage.
• If the radiant tubes must pass through the building
structure, be sure that adequate sleeving and fire
stop is installed to prevent scorching and/or fire
hazard.
SECTION 3: CLEARANCES TO COMBUSTIBLES
NOTE: 1. All dimensions are from the surfaces of all tubes, couplings and elbows.
2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream
from where the burner and burner tube connect.

or of the combustion air inlet of any other appliance.
SECTION 8: VENTING
8.2 Unvented Operation
Sufficient ventilation must be provided in the amount
of 4 cfm per 1000 Btu/h firing rate (United States); 3
cfm per 1000 Btu/h firing rate (Canada).
Use of optional outside combustion air is not
recommended with unvented heaters.
If exhaust fans are used to supply ventilation air, an
interlock switch must be used to prevent the heater
from coming on when the fans are off. This may be
done using a pressure switch.
WARNING
Combustion by-products contain a chemical

cancer and birth defects or other
reproductive harm.
8.3 Horizontal Venting
In noncombustible walls only, vent terminal
(P/N 02537801-1P) may be used.
For 4" (10 cm) vents in either combustible or
noncombustible walls, use Tjernlund VH1-4 (P/N
90502100) or equivalent, insulated vent terminal.
Follow the manufacturer's instructions for proper
installation.
FIGURE 22: Tube Termination
8.6 Length Requirements
The maximum vent length allowed is 45' (13.7 m).
The maximum outside air supply duct length allowed
is 45' (13.7 m).
The total vent length, plus outside air duct length,
plus any extensions to minimum heat exchanger
lengths, cannot exceed 65' (19.8 m).
Vent length should be limited to less than 20' (6 m). If
using vent lengths greater than 20' (6 m),
condensation will form in the vent pipe. Insulation
and additional sealing measures (high temperature
silicone at all seams) are required. Optional heat
exchanger beyond minimum lengths is considered as
vent length for length determination.
Subtract 15' (4.6 m) of maximum allowed vent or duct
length per vent elbow if more than two are used.
For 6" (15 cm) common vents in either combustible
or noncombustible walls, use Tjernlund VH1-6 (P/N

SECTION 9: GAS PIPING
SECTION 9: GAS PIPING
WARNING
Fire Hazard
Tighten gas hose fittings to connect gas
supply according to Figure 23.
Gas hose can crack when twisted.
Gas hose moves during normal operation.
Use only 36" (91 cm) long connector of 1/2" or
3/4" nominal ID.
Connector supplied with heater for U.S.
models (not with Canadian models).
Failure to follow these instructions can result
in death, injury or property damage.
WARNING
Explosion Hazard
Leak test all components of gas piping
before operation.
Install the gas hose as shown on Page 42, Figure 23.
The gas hose accommodates expansion of the
heating system and allows for easy installation and
service of the burner. Before connecting the burners
to the supply system, verify that all high pressure
testing of the gas piping has been completed.
There is an expansion of the tube with each firing
cycle; this will cause the burner to move with respect
to the gas hose. This can cause a gas leak resulting
in an unsafe condition if the gas connection is not
made strictly in accordance with Figure 23 on Page
42.
Meter and service must be large enough to handle all
the burners being installed plus any other connected
load. The gas hose which feeds the system must be
large enough to supply the required gas with a
maximum pressure drop of 1/2" w.c. When gas piping
is not included in the layout drawing, the local gas
supplier will usually help in planning the gas piping.
Gas lines must meet applicable codes:
United States: The Flexible Stainless Steel Gas
Hose (US models) supplied with the heater is certified per the Standard for Connectors for Gas Appliances, ANSI Z21.24/CSA 6.10 - latest revision.
Canada: The Rubber Type 1 Gas Hose (Canadian
models) optional with the heater is certified as being
in compliance with the Standard for Elastomeric
Composite Hose and Hose Couplings for Conducting
Propane and Natural Gas, CAN/CGA 8.1 - Latest
revision.
• Check the pipe and tubing ends for leaks
before placing heating equipment into
service. When checking for gas leaks, use a
soap and water solution; never use an open
flame.
Gas can leak if piping is not installed
properly.
Do not high pressure test gas piping with
equipment connected.
Failure to follow these instructions can result
in death, injury or property damage.

WARNING
DANGER
Electrical Shock Hazard
Disconnect electric
before service.
Explosion Hazard
Turn off gas supply to
heater before service.
More than one
disconnect switch may
be required to
disconnect electric from
heater.
Burn Hazard
Allow heater to cool
before service.
Cut/Pinch Hazard

after operation.
Heater must be
connected to a properly
grounded electrical
source.
Failure to follow these instructions can result in death, electric shock, injury or property damage.
This heater is equipped with a direct spark ignition
system.
11.1 Sequence of Operation
1. Turn the thermostat up. When the thermostat
calls for heat, the blower motor will energize.
2. When the motor approaches nominal running
RPM, the pressure switch closes and activates
the ignition module.
3. After a 45 second prepurge, the ignition module
then opens the gas valve and energizes the
spark igniter.
4. When the flame is established, the sparking
sequence ceases.
5. If the flame is not established during the ignition
sequence, the ignition module closes the gas
valve and purge begins. Module will try 2
additional times for ignition (with purges in
between trials). If ignition is not established, the
module will lockout.
6. If the flame extinguishes during operation, the
ignition module will attempt the multiple trial
sequence described in step 5. If ignition is not
re-established, the module will lockout for one
hour or until reset.
7. After lockout, the control can be reset by turning
down thermostat for five seconds, and then
raising it again to desired temperature, or by
disconnecting power and then reconnecting.
8. When thermostat is satisfied, all power to the
unit is shut off.
11.2 To Shut Off Heater
Set thermostat to lowest setting.
Turn OFF electric power to heater.
Turn OFF manual gas valve in the heater supply line.
11.3 To Start Heater
Turn gas valve and electric power OFF and wait five
minutes for unburned gases to vent from heater.
Turn ON main gas valve.
Turn ON electric power.
Set thermostat to desired temperature.
Burner should light automatically.
11.4 Pre-Season Maintenance and Annual
Inspection
To ensure your safety and years of trouble-free
operation of the heating system, service and annual
inspections must be done by a contractor qualified in
