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 registered installer/contractor qualified in
the installation and service of gas-fired heating
equipment.
Read this manual carefully before installation, operation
or service of this equipment.
This heater is designed for heating nonresidential indoor
spaces. Do not install in residential spaces. These
instructions, the layout drawing, local codes and
ordinances, and applicable standards that apply to gas
piping, electrical wiring, venting, etc. must be thoroughly
understood before proceeding with the installation.
Protective gear is to be worn during installation, operation
and service. Thin sheet metal parts, such as the reflector
portion of the heater and the various venting
components, have sharp edges. To prevent injury, the use
of work gloves is recommended. The use of gloves will
also prevent the transfer of body oils from the hands to
the surface of the reflector.
Before installation, check that the local distribution
conditions, nature of gas and pressure, and adjustment of
the appliance are compatible.
The heater must be applied and operated under the
general concepts of reasonable use.
For additional copies of the Installation, Operation and
Service Manual, please contact Roberts-Gordon LLC.
Figure 1: Bottom and Back Panel Label Placement
1.1 Manpower Requirements
To p re vent personal injury and damage to the heater, two
persons will be required for installation.
1.2 IP55 Protection
The burner is certified to protection class of IP55. This
means that the internal components of the burner are
protected against extreme dusty atmosphere and water
jets from all sides. Outside air supply and flue are
mandatory for this heater. The standard exhaust fans
mentioned in this manual do NOT have IP55 protection
and must be outside the wet environment. If the fan is to
be installed in the wet environment, a special IP54
protected fan must be used. Consult Roberts-Gordon
LLC for alternative exhaust fans. Optional stainless steel
burner box provides long life in the most corrosive
applications. Always ensure that the environment to be
heated is not of an explosive or flammable nature. For
more information, please consult your ROBERTS
GORDON
®
independent distributor.
In order to have trouble free performance of your heater
and maintain the IP55 protection, follow all instructions in
this manual, especially the replacement of sealing
gaskets.
1.3 Safety Labels and Their Placement
Product safety signs or labels should be replaced by the
product user when they are no longer legible. Please
contact Roberts-Gordon LLC or your ROBERTS
GORDON

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.
SECTION 2: INSTALLER RESPONSIBILITY
• To install the heater, as well as the gas and electrical
supplies, in accordance with applicable specifications
and codes. Roberts-Gordon LLC 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 to burners for servicing on all
sides, for burner removal.
• To provide the owner with a copy of this Installation,
Operation and Service Manual.
• To never use heater as support for 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 33 kg.
• To ensure the heater is placed in an approved
application.
2.1 Low Level User Instructions
In all situations, clearances to combustibles must be
maintained. Signs should be posted in storage areas to
specify the maximum stacking height of items placed
below heater to maintain required clearances to
combustibles. Minimum clearances must be maintained
from vehicles parked below the heater. Caution should be
used when running the system near combustible
materials such as wood, paper, rubber, etc. Consideration
should be given to partitions, storage racks, hoists,
building construction, etc.
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 Roberts-Gordon or your ROBERTS
GORDON
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).
A copy of the wall tag (P/N 91037912) is illustrated on the
back cover. This copy of the wall tag can be affixed 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. Write the
largest clearance dimensions with permanent ink
according to your model number and configuration in the
open spaces on the tag.
®
independent distributor to obtain the wall tag.
2.2 Corrosive Chemicals
Roberts-Gordon LLC 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 lifespan 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.
The heater must not be operated in environmental
temperatures below 0° C.

SECTION 3: CLEARANCES TO COMBUSTIBLES
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.
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 fire
hazards. Caution should be used when running the
system near combustibles. 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 Page 6,
Figure 3 through Page 9, Figure 16 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 petrol or other combustible materials including
flammable objects, liquids, dust or vapours away from
this heater or any other appliance.
• The stated clearances to combustibles represents a
surface temperature of 32°C (90° F) above room tem-
perature. 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 Building Inspector, Fire Insurance
Carrier or other authorities for approval of proposed
installation when there is a possibility of exposure to
combustible airborne materials or vapours.
• Hang heater in accordance to the minimum
suspension requirements on Page 11, Section 5.

2. The overlap at the first and second reflector is a slip
overlap. Thereafter, every third reflector joint is a
slip overlap. A slip overlap is achieved by either:
a.) both reflectors lay inside a hanger.
(no reflector support needed).
b.) using a reflector support with
loose screws at the reflector
overlap.
3. The remaining reflector overlaps require a
non-slip overlap connection. To affix the
reflectors together in a non-slip overlap
either:
a.) use reflector support and tight screws.
b.) if both reflectors lay inside a hanger,
u-clips or sheet metal screws may be
used.

2. The overlap at the first and second reflector is a slip
overlap. Thereafter, every third reflector joint is a
slip overlap. A slip overlap is achieved by either:
a.) both reflectors lay inside a hanger.
(no reflector support needed).
b.) using a reflector support with
loose screws at the reflector
overlap.
3. The remaining reflector overlaps require a
non-slip overlap connection. To affix the
reflectors together in a non-slip overlap
either:
a.) use reflector support and tight screws.
b.) if both reflectors lay inside a hanger,
u-clips or sheet metal screws may be

BLACKHEAT® HE INSTALLATION OPERATIONAND SERVICE MANUAL
WARNING
Fire Hazard
Tighten gas line fittings to connect gas supply
according to Figure 32.
Flex gas line can crack when twisted.
Gas line moves during normal operation.
Use only 1000 mm long connector of 1/2" or
3/4" nominal ID.
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.
Gas can leak if piping is not installed
properly.
Do not high pressure test gas piping with
heater connected.
Failure to follow these instructions can result
in death, injury or property damage.
SECTION 12: GAS PIPING
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 in strict
accordance with Figu re 32.
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 13 mm wc. When gas piping is not
included in the layout drawing, the local gas supplier will
usually help in planning the gas piping.
IMPORTANT - the complete installation must be tested
for gas soundness and be purged in accordance with
local and national codes.
• 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.
It is important that the gas supply pipe and electrical
connections do not support any of the heater’s weight.
Installation pipes should be fitted in accordance with
National Standards. Pipe work from the meter to the
heater(s) must be of adequate size. Pipes of smaller size
than the heater inlet gas connection should not be used.
Install the gas hose as shown on Page 53, Figure 32. 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.

SECTION 13: WIRING
Connect to the electrical supply using the power wire
coming out of the wire gland via a locally mounted IP55
protected double pole fused switch having a minimum
disconnection of 3 mm on each pole. This switch should
be fused to 3 amps. There are no control connections in
the standard burner. Control is affected by interruption of
the main power inlet. See Page 54, Section 13.1 through Page 55, Section 13.4 for the external wiring details for
the single-burner, double linear and multiburner heater
systems.
If the IP55 protected fan MB 56 2BM is used with a single
burner (linear or U-tube), it must be wired as shown on Page 55, Section 13.2.
The fan must be protected with a 3 A fuse.
If the heater lockout indication is required, a
BLACKHEAT® HE lockout indicator package (P/N
03360008) must be installed in every burner. Drill a 20.5
mm hole to fit the wire gland. See Page 56, Section 13.5
for wire connections. Remove the taps from the power wire.

14.2 Testing
Establish that a satisfactory purged gas supply and an
electrical supply is available to the heater. Ensure that all
time clocks and thermostats are set to call for heat.
With the gas supply cut off and the electrical supply
isolated by switching off at the local switch, open the
control chamber secured by the screws. Loosen the
sealing screw from the pressure test point and remove
the cover cap from the governor.
Turn on the gas supply and connect appliance electrical
plug. Ensure that the timer or thermostat, if fitted, are set
to call for full gas rate. Switch on at the local switch. The
sequence as described should take place. If not, refer to
detailed fault finding sequence. When flame is
established, check the gas pressure reading and adjust if
necessary. Refer to burner data label.
Check the gas pressure at the outlet of the gas valve. See Page 73, Section 18.9.1 for pressure settings or refer to
the data plate.
Switch off the electrical supply (shutting down the heater),
remove pressure gauge, tighten pressure test point
screw, ensuring a tight gas seal. Replace governor cover
cap. Replace control chamber door.
14.3 Commissioning (Multiburner)
1. Establish that a satisfactory purged gas supply and
an electrical supply is available to the heater.
5. Switch on the electrical supply at the main isolator.
This will start the exhaust fan.
6. Balancing Cold Suction
Check each burner vacuum by connecting an
inclined pressure gauge to the tee on the pressure
switch inlet side in the burner. Adjust the damper so
that the suction is 1.9 mbar. Repeat for each burner.
7. Start at the end burner (furthest from the exhaust
fan) with the inclined pressure gauge connected as
described above. Turn on the gas and electrical supply, reset the pressure switch by removing suction
from the inlet side of the pressure switch waiting
several seconds and reconnecting. The start up
sequence described on Page 57, Section 14 should
take place. If not, refer to detailed fault finding
sequence. When flame is established, check the
gas pressure reading and adjust if necessary. See
data label.
Check the gas pressure at the outlet of the gas
valve. See Page 73, Section 18.9.1 for pressure set-
tings or refer to the data plate.
Switch off the electrical supply (shutting down the
heater), remove pressure gauge, refit pressure testpoint screw, ensuring a tight gas seal. Replace gov-
ernor cover cap.
Repeat this procedure for each burner in the system.
Close the control chamber and secure with six
screws.
8. Balancing Hot Suction
Reconnect all the burners on the system and allow
them to reach full operating temperature (approximately 20 minutes). Return to each burner and
recheck the hot suctions at the tee on the inlet to the
pressure switch. Re-adjust the damper so that the
hot suction of 1.7 mbar is achieved and lock the
damper in position.
14.4 System Checks
Switch on again at the local switch to help ensure smooth
ignition. Carry out the following system checks:
When running, turn off the gas supply at the appliance.
The heater will immediately shut down followed by one
attempt at restoration followed by lockout.
Linear and Double Linear only:
When running, disconnect the fan plug from the burner.
The unit should shut down within three seconds, proving
operation of the pressure switch.
2. ENSURE that all the dampers are in the fully open
position.
3. With the gas supply off at each of the burners and
the electrical supply isolated, open the control
chamber secured by six screws.
4. Ensure that all time clocks and thermostats are set
to call for heat.

SECTION 15: SERVICING INSTRUCTIONS
Cut/Pinch Hazard
Wear protective gear
during installation,
operation and service.
Edges are sharp.
WARNING
Failure to follow these instructions can result in death, electric shock, injury or property damage.
Burn Hazard
Allow heater to cool
before service.
Tubing may still be hot
after operation.
Explosion Hazard
Turn off gas supply to
heater before service.
DANGER
Electrical Shock Hazard
Disconnect electric
before service.
More than one
disconnect switch may
be required to
disconnect electric from
heater.
Heater must be
connected to a properly
grounded electrical
source.
SECTION 15: SERVICING INSTRUCTIONS
IMPORTANT: Never use the heater as a support for
ladders or other access equipment. Always test for gas
soundness with a suitable detection fluid after completing
any servicing or exchange of gas carrying component.
On completion of any service/fault finding tasks which
require the breaking and remaking of electrical
connections, the checks:- A: Earth Continuity, B: Polarity
and C: Resistance to Earth must then be repeated.
15.1 Annual Procedure
Carry out the following procedure annually. The preferred
time would be immediately before the winter heating
period. If very dirty conditions arise, it may be necessary
to carry out this procedure more often. If the unit takes in
air through an air duct or filter assembly, more frequent
service may be necessary.
15.1.1 Burner and Fan Removal
Isolate the heater from the gas and electrical supplies.
Remove the fan plug from the burner. Unscrew the
securing screws on the burner flange. The burner can
now be removed. Take care not to disturb the gasket on
the flanged burner tube. Unscrew the securing screw on
the fan flange spigot. The fan can now be removed.
15.1.3 Tube and Reflector Maintenance
With burner and fan removed, clean the outer surfaces of
the tubes using a brush and wipe the inner surface of the
reflector with a soft damp cloth - use a household
detergent if necessary. Never use abrasive cleaners on
the reflectors. Reassemble the burner and fan in reverse
order. Carry out the Testing Procedure. See Page 58, Section 14.2.
15.2 Sealing Gaskets
During annual service, all gaskets, as indicated on Page
68, Section 17, must be inspected for cuts, misalignment
or dryness. All round rubber gaskets, sealing the screw
holes, must be replaced in three year intervals or earlier
as needed. All other gaskets must be replaced every five
years or earlier as needed.
Old gaskets must be removed completely before installing
the new gasket. When replacing gaskets on screws,
ensure that the screws are not over tightened.
Deformation of the gasket is an indication of suffcient
torque. The control and combustion chamber doors have
internal seals, replacements must be attached to the
same location.
15.1.2 Burner and Fan Removal Maintenance
Remove the fan and burner independently to floor level
and clean both items internally using a soft brush and
compressed air, if available. Take care not to damage the
internal parts of the burner. Check fan impeller for
cleanliness and free rotation.
The electrodes are an integral part of the burner. To
check spark gap, remove the securing screws on the
electrode and withdraw it ensuring the gasket is not
damaged. Spark gap on electrode should be
approximately 3 mm.
First, isolate the heater from the gas and electricity
supply.
Entry to the burner assembly is gained by removing the
six door screws and removing the control chamber door.
Entry to the combustion chamber is gained by removing
the combustion chamber door.
