THAT THE FOLLOWING POINTS HAVE BEEN CAREFULLY CONSID-
ERED.

1.4.1 Highly elevated installations:

1. Do you have the proper equipment to install and
maintain the system in the proposed location?

2. Do you have suitable equipment to access the sys­tem for maintenance after the system is installed?

3. Will the proposed location allow future access to
the system (i.e., will machinery be erected at a later
date that may make access to the system difficult
or impossible)?

NO

TE:

lean ladders against a suspended
heater system. The BH unitary systems
employ a non-rigid attachment system that
will not support external apparatus.

4. Is the installed height within the parameters speci­fied by the manufacturer?

1.4.2 Ventilation/Air Supply:

1. Will a flue be added to the system? If so, have you
checked the flue recommendations specified by
the manufacturer?

2. Is there an adequate supply of fresh air to support
combustion

1.4.3 Environment of the Facility:

1. Are there halogenated hydrocarbons* and/or other
combustible materials (i.e., cleaning agents, wood,
paper, rubber, etc.) within the area to be heated?- If
so, is there adequate exhaust ventilation and clear­ances?

NO

TE: In poorly vented, dusty areas, fresh outside

air should be provided to prevent premature
aging of the equipment.

In very dusty areas (i.e., woodworking facili­ties) regular dusting of the tubes and reflec­tors is essential as a fire preventative
measure.

1.4.4 Clearances to Combustibles:

1. Be sure that the clearances (as recommended by
the manufacturer) to halogenated hydrocarbons
and/or other combustible materials is observed.

2. Be sure that the manufacturer recommended
clearances between the heater system and vehi­cles parked below are maintained.

3. Be sure that signs are posted in storage areas to
specify maximum stacking height below the heater
system.

4. 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 risk of

* 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 may be invalidated if the heater is exposed to halogenated hydro­carbons.

The Blackheat BH is a gas-fired, vacuum-assisted, low­intensity radiant heating system. The BH was devel­oped by Blackheat in partnership with
Roberts-Gordon, who pioneered low-intensity heating
in 1962 with their revolutionary CoRayVac system.

Please note that the Blackheat BH is available in sev­eral configurations. This manual describes the single
burner and double linear versions. The single burner
systems are available in both linear tube and U-tube
configurations. The double linear systems are com­prised of two linear heaters with a common fan
assembly.

Optionally, HiLo models are available that incorporate
an extra solenoid valve to operate at a low (approx
80%) rate. Linked to a secondary thermostat, this pro­vides a low rate at an intermediate setting below the
“off” stat. These models are described in manual
174900UK.

Multi-burner systems are covered in manual
172101UK. These systems manifold several heaters
to a single vacuum pump.

11..22 AABBOOUUTT RRAADDIIAANNTT HHEEAATT

Radiant heat is the most effective way of providing
comfortable environmental conditions in large open
spaces. Radiant energy operates like light, travelling in
straight lines and can be directed to specific individu­als and areas which require heating. Comfort levels
are created when the radiant energy is absorbed by
the floor, plant and machinery, and lower walls without
initially losing energy to the air space between.

The objects which have absorbed the radiant energy in
turn release heat to the air and act as low power radi­ators. In this way, all useable energy is absorbed and
utilised in the occupied zone – the lower 2 metres –
not in the entire structure and roof space. Comfort
conditions are achieved using lower air temperatures
and as a result lower heat losses with a subsequently

lower fuel bill.

3.4.1 Prepare a work area corresponding to the size of
heater selected. The area should be clear and free of
debris. The manufacturers approved layout drawing
should be referred to so that the work area is conve­nient for the final system position.

3.4.2 Layout the appropriate Figure (3, 4, or 5 depending on
heater model) and keep it at a convenient place for
frequent reference. Pull out every part from the pack­age and lay them out roughly at the position shown in
the assembly drawings. For BH35UT and BH40UT
make sure that the end of the fan tube with the swirler
points away from the U-bend. Keep the bolts and
screws at a convenient place for later usage.

3.4.3 With the suspension holes uppermost, slide the first
and intermediate brackets onto the fan and burner
tubes. For Model BH15, there is no intermediate
bracket. In the following assembly procedures, please
pay attention to this point.

3.4.4 Use two bolts to connect the U-bend and end bracket
together with the suspension holes uppermost. Insert
the plain ends of the burner tube and fan tube into the
two legs of the U-bend, and secure them with four
bolts.

3.4.5 Place intermediate bracket over the ends of the
tubes. Slide bracket onto tubes approximately 500
mm.

3.4.6 Join the burner tube and the remaining plain end tube
using the couplings and bolts provided. See section

4.4.5 for details.

3.4.7 Place the reflectors over the brackets as shown in the
assembly diagrams, and secure them using six screws
at each end. Seal the seam on top of the reflectors
using U-clips at least every 300 mm.

NOTE: Remove PVC coat from stainless steel reflec-

tors.

3.4.8 Insert the quick-links into the holes at the top edges of

the end, intermediate and first brackets.

3.4.9 Prepare the hanging chains at the position where the
heater will be located. Suspend the heating system as
recommended below. Use the center holes of the end
and first bracket to lift the heating system into posi­tion. Chains used should have 100 kg minimum
breaking load and preferably should be galvanised
finish. Figure 2 shows two suspension methods.
Method A is recommended because it provides a
semi-rigid suspension. Method B is acceptable.

Figure 2. Bracket Suspension

3.4.10 Never lift the assembled heater by passing ropes
around the reflector which would cause severe dam­age to the reflectors.

3.4.11 When angle mounting the heater, the burner tube
must be the tube nearest the floor and the fan tube is
always furthest from the wall (when suspended adja­cent to a wall). It is recommended wherever possible
that the heater is suspended from above from
unequal length chains to effect the necessary angle
(maximum 20° from horizontal). Always allow extra
lengths of chain so that adjustment of angle can be
made to provide the best heat distribution for your
customer.

3.5.1 Place the gasket on the flange of the burner tube.
Carefully insert the flanged end into the burner box.
Secure the burner on the burner tube using the four
mounting bolts and washers. Use a spanner to tighten
the bolts evenly.

3.5.2 Place the fan assembly onto the end of the last fan
tube. Slide the fan assembly up to its stop. Tighten
the pinch screw on the assembly making sure that the
fan outlet is positioned as required.

premises.

4.2 RELATED DOCUMENTS

Notwithstanding their limited scope, the appliance
should be installed in accordance with relevant
National Codes.

4.3 CLEARANCES TO COMBUSTIBLES

Before proceeding with installation, ensure that
proper clearances to combustible materials will be
observed in the final installed position of the heater.
Clearance distances may be found in Section 2 of
these instructions.

44..44 IINNIITTIIAALL AASSSSEEMMBBLLYY

4.4.1 Prepare a work area corresponding to the size of
heater selected. The area should be clear and free of
debris. The manufacturers approved layout drawing
should be referred to so that the work area is conve­nient for the final system position.

4.4.2 Layout the appropriate Figure (9, 10, 11, or 12,
depending on heater model) and keep it at a conve­nient place for frequent reference. Pull out every part
from the package and lay them out roughly at the
position shown in the assembly drawing. Keep the
bolts and screws at a convenient place for later
usage.

4.4.3 Prepare the hanging chains at the position where the
heater will be located. Chains used should have 100
kg minimum breaking load and preferably should be
galvanised finish. Assemble the two halves of the tube
clamp package using the hex carriage bolt, hex nut
and flat washer. Attach the clamp to the tube and
reflector hanger, and slide the hanger into place on
the burner tube (see Figure 6).

4.4.4 The hanger must be located within 150 mm of the
flange. Slide the next tube and reflector hanger onto
the end of the burner tube. Making sure that the sus­pension hooks of the hangers are uppermost, lift the
burner tube into the position required. Suspend the
burner tube by connecting the tube and reflector
hangers to chains using the quick links provided.

4.4.5 Slide another tube and reflector hanger onto the next
tube and locate it according to the appropriate Figure.
Lift the tube into its position and connect it with the
burner tube using a stainless steel coupling. Repeat
this procedure to suspend the remaining tube(s) and
connect them to the heater one by one.

4.4.6 For details of the coupling connection, see the follow­ing diagram:

Figure 8. Coupling Assembly

To assemble the coupling, hook the free end of the
coupling sleeve into the lanced clip. Place the wide
end of the tapered slide bar on the coupling so that it
moves toward the lanced clip. Insert the two tube ends
into the coupling. Be sure the tube ends are in line
and are flush against the stop pins inside the cou­pling.

Hammer-drive the slide bar until the coupling is
secured snugly to the tubes. Overdriving the slide bar
will distort the coupling or slide bar lip and will
decrease the holding capability of the coupling.

National Codes.

5.3 CLEARANCES TO COMBUSTIBLES

Before proceeding with installation, ensure that
proper clearances to combustible materials will be
observed in the final installed position of the heater.
Clearance distances may be found in Section 2 of
these instructions.

55..44 IINNIITTIIAALL AASSSSEEMMBBLLYY

5.4.1 Prepare a work area corresponding to the size of
heater selected. The area should be clear and free of
debris. The manufacturers approved layout drawing
should be referred to so that the work area is conve­nient for the final system position.

5.4.2 Establish both the centre point for the unit, and the
centre line of the heater run within the area to be
heated. Along the established centre line of the heat­ing run, layout two of the appropriate heater configura­tions (Figure 9, 10 or 11). The burner assemblies
should be at opposite ends of the heater run and
should be configured as shown in Figure 13.

5.4.3 At a point directly above the established centre of the
heater system, install a suspension chain for the fan
assembly. Moving outward from this point, and along
the established centre line, establish the remainder of
the chain suspension locations.

5.4.4 Suspend the tube and reflector hangers for the fan
tube, and raise the fan tubes into position.

5.4.5 Assemble the two halves of the tube clamp package
using the hex carriage bolt, hex nut and flat washer.
Attach the clamp to the tube and reflector hanger, and
slide the hanger into place on the burner tube (see
Figure 6).

5.4.6 The hanger must be located within 150 mm of the
flange. Slide the next tube and reflector hanger onto
the end of the burner tube. Making sure that the sus­pension hooks of the hangers are uppermost, lift the
burner tube into the position required. Suspend the
burner tube by connecting the tube and reflector
hangers to chains using the bow shackles provided.
Repeat procedure for the burner tube at the other end.

5.4.7 Connect the burner and fan tubes using the stainless
steel couplings. Raise the centre tee into position

SSeeccttiioonn 55.. DDoouubbllee LLiinneeaarr HHeeaatteerr IInnssttaallllaattiioonn

between the end of the fan tubes and secure using
the damper couplings provided.

5.4.8 Slide another tube and reflector hanger onto the next
tube and locate it according to the appropriate Figure.
Lift the tube into its position and connect it with the
burner tube using a stainless steel coupling. Repeat
this procedure to suspend the remaining tube(s) and
connect them to the heater one by one. For details of
the coupling connection, see Figure 7.

5.4.9 To assemble the coupling, hook the free end of the
coupling sleeve into the lanced clip. Place the wide
end of the tapered slide bar on the coupling so that it
moves toward the lanced clip. Insert the two tube
ends into the coupling. Be sure the tube ends are in
line and are flush against the stop pins inside the cou­pling.

Hammer-drive the slide bar until the coupling is
secured snugly to the tubes. Overdriving the slide bar
will distort the coupling or slide bar lip and will
decrease the holding capability of the coupling.
Coupling should be tight when the slide bar is ±50
mm from the end of the coupling.

5.4.10 Place a reflector over the flanged burner tube and
slide it inside the first tube and reflector hanger. Slide
the next reflector under the first reflector. Overlap the
reflectors using the distance specified in the assem­bly drawings. Secure the two reflectors in place using
the reflector support straps. Assemble the reflector
support strap (see Figure 8).

NOTE: Remove PVC coat from stainless steel reflec-

tors.

5.4.11 Attach the remaining reflectors to the heater using the
same method. Be sure to alternate the overlap of the
reflectors as shown in the assembly drawings.
Starting at the first reflector support, and alternating
every other support down the length of the heater, the
screws should be loosened 2 mm to allow for expan­sion of the heating tubes during operation.

5.4.12 After assembling the reflectors, attach the reflector
end caps to the open ends of the reflectors. Punch out
the center section of the end cap, and attach the end

77..11 GGEENNEERRAALL RREEQQUUIIRREEMMEENNTTSS

Heater must be vented in accordance with the proper
national and local codes. The fan may vent to the out-
doors either vertically or horizontally (see Figure 20).
For horizontal venting:

1. Vent must exit building not less than 2.1 m above
grade when located adjacent to public walkways.

2. Vent must terminate at least 1 m above any forced

air inlet located within 3 m.

3. Vent shall terminate at least 1.2 m below, 1.2 m

horizontally from, or 0.3 m above any door, window
or gravity air inlet into building.

4. Locate vent terminal at least 3 m from any open-

ing through which vent gases could enter a build­ing.

5. Use only corrosion resistant materials for the dis-

charge line from the fan to the point of discharge.

6. Vent terminal opening must extend beyond any

combustible overhang.

7. Install vent terminal at a height sufficient to pre-

vent blockage by snow.

8. Protect building materials from degradation by flue

gases.

9. Any portion of flue pipe passing through a com-

bustible wall must be dual insulated or an
approved thimble must be used.

77..22 FFLLUUEE IINNSSTTAALLLLAATTIIOONN

The fan outlet may discharge vertically or horizontally.
Connection should be made using 100 mm minimum
diameter Aluminium or Stainless Steel flue material to
National Standard and must be adapted to insert into
the 100 mm flue adapter. The combined length of flue
run plus fresh air inlet duct should not exceed 16000
mm. Do not use bends in excess of 45°. Consult the
manufacturer if more than 2 x 45° offset bends are
necessary. The flue must be self supporting.

77..33 FFLLUUEELLEESSSS IINNSSTTAALLLLAATTIIOONN ((UU..KK.. OONNLLYY))

If the heater is being installed in an area where com­bustion products can be dissipated within the build­ing, ensure that the fan outlet is horizontal and away
from the burner. Where installation is close to a wall
(Perimeter system) or other obstruction close to the
fan outlet or wall angle mounted, install the heater so
that the fan tube is the tube furthest from the wall or
obstruction, i.e. the fan will always blow into the build­ing or away from the obstruction.

Figure 18. Flue Connection Detail

77..44 VVEENNTTIILLAATTIIOONN RREEQQUUIIRREEMMEENNTTSS

Detailed recommendations for air supply are given in
the relevant National Standards. There must be an
adequate supply of air for both combustion and gen­eral ventilation. Air vents should have negligible resis­tance. Do not locate air vents where they can be easily
blocked or flooded, or adjacent to any flues or extrac­tion systems carrying flammable vapour.

7.4.1 Flued Installation

Where the heater(s) is flued the space containing it
must have a permanent outside air vent with a mini­mum effective area of 4.5 cm

2

per kW of heat input. If
mechanical ventilation is employed, the minimum
proven airflow rate shall be 2.35m

3

/h per kW of heat

input.

If the flue is to be horizontally vented through a wall, a
wind-proof terminal must be fitted to outdoor vent pipe
to prevent a back draught.

7.4.2 Flueless Installation

Minimum airflow rate shall be 37.5m

3

/h per kW of
total rated heat input where mechanical ventilation is
used. Where the air change rate is below this min­imum, provide additional openings equal to 52 cm

2

per kW total rated heat input; or 1.45 cm2 for each
1m

3

/h per kW below 37.5m3/h per kW of total rated

heat input.

On connection of power supply the fan motor will start
creating a suction in the tube. Power is also supplied,
via a relay safety circuit, to the fan proving switch and
when suction is created, changes contacts to feed
power to the Automatic Control Unit. At this stage one
neon will light up.

8.1.1 Power to the control causes initiation of an approxi­mate ten (10) seconds purge period following which
the solenoid valves open passing gas at a full rate to
the burner. At the same time a spark is created and
ignition should take place. If ignition of the gas is not
successful the spark will cease and the solenoid will
close after approximately ten (10) seconds. Lockout
will occur. If the gas is ignited, the detection circuit is
energised and switches off the ignition circuit. Both
neons will now light up indicating full running condi­tion.

8.1.2 The heater will continue to run until the power supply
or gas supply is interrupted. Interruption of the electri­cal supply results in the shutdown of the heater.
Restoration will restart the whole sequence.
Interruption of the gas supply results in loss of flame
followed by one attempt at reignition followed by lock­out if unsuccessful.

88..22 TTEESSTTIINNGG

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.

8.2.1 With the gas supply cut off at the appliance isolating
cock and the electrical supply isolated by switching off
at the local switch and removing the appliance inlet
plug, open the control chamber secured by the centre
screw. Remove the sealing screw from the pressure
test point and remove the cover cap from the gover­nor.

8.2.2 Turn on appliance isolating cock 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. See data
label.

8.2.3 Check the gas pressure at the outlet of the gas valve
to ensure minimum 8.7 mbar (3.5 in. w.g.) pressure
for G20 natural gas or 27 mbar (10.5 in. w.g.) pressure
for propane. See Section 2 for G25 and Butane set­tings.

8.2.4 Switch off the electrical supply (shutting down the
heater), remove pressure gauge - refit pressure test­point screw, ensuring a tight gas seal. Replace gover­nor cover cap. Close burner side cover.

88..33 SSYYSSTTEEMM CCHHEECCKKSS

Switch on again at the local switch to ensure smooth
ignition. Carry out the following system checks.

8.3.1 When running turn off the gas supply at the appliance
isolating cock. The heater will immediately shut down
followed by one attempt at restoration followed by
lockout.

8.3.2 When running disconnect the fan plug from the
burner. The unit should shut down within three sec­onds proving operation of the pressure switch.

88..44 UUSSEERR IINNSSTTRRUUCCTTIIOONNSS

Having satisfactorily tested these Blackheat units
ensure that the client is fully aware of the operation of
the system. Bring this manual to the attention of the
user or purchaser; instruct them in the safe operation
of the heater(s). Advise the user that if the system is
unflued, any reduction in the natural ventilation of the
building may require a flue to be fitted, or additional
ventilation grills will be required.

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 then the checks:- A:Earth
Continuity, B:Polarity and C:Resistance to Earth must
be repeated.

99..11 AANNNNUUAALL PPRROOCCEEDDUURREE

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.

9.1.1 Isolate the heater from the gas and electricity supply
by shutting off the appliance cock and disconnecting
the union connector, switching off the local electrical
supply and removing the appliance plug.

9.1.2 Remove the fan plug from the burner. Unscrew the
securing screws on the burner flange. The burner can
now be removed. Unscrew the securing screw on the
fan flange spigot. The fan can now be removed.

9.1.3 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 that free rotation is avail­able. When removing burner take care not to disturb
the gasket on the flanged burner tube.

9.1.4 The electrodes are an integral part of the Burner
Head. 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.

9.1.5 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 the reflectors.

9.1.6 Re-assemble the burner and fan in reverse order.

The Blackheat Warranty means that only the best
material and workmanship are employed in the manufac­ture of Blackheat products.

WARRANTY COVERAGE:

Blackheat Ltd. (“Seller”) warrants that entire heating
systems sold by it (individually a “System”) and any replace­ment parts which it sells relating to any System (“Parts”)
shall be free from defects in workmanship and material for
the time periods described as follows. With respect to a
System this warranty shall apply for a period of one year
from delivery to the original purchaser (“Buyer”). With
respect to Parts, this warranty shall apply for the longer of
the original System warranty period or for a period of one
year. (“Systems” and “Parts” are hereinafter collectively
referred to as “Products”.) This warranty extends only to the
original purchaser of Products.

Seller manufactures products which are designed only
to provide predetermined ranges of heat rises in various
enclosures when properly used in systems designed by pur­chaser or others and installed by others. Seller makes no
representation or warranty with respect to the effect upon
enclosure, or upon any of the contents of the enclosure,
including, without limitation, all plant or animal life, kept or
processed in the enclosure subject to the limitations out­lined below.

WARNING:

This warranty is void if the products have been dam­aged due to accident, abuse, mishandling or any other
cause whatsoever other than defects in material or work­manship. Specifically, Seller’s warranty shall not apply: (a)
to damage to Products when used in an atmosphere con­taining halogenated hydrocarbons or other corrosive chem­icals. Some compounds in the air can be ingested into the
equipment and can cause an accelerated rate of corrosion
of some of the Products. The use of such chemical com­pounds in or near the enclosure should be avoided where:
(a) longer life of the burner, tubing and other parts is desir­able; (b) to any damage when used in the vicinity of any
combustible or explosive materials; (c) to Products which
have been repaired or replaced with other than factory
parts, modified in any way, misused or damaged, or which
have been installed or used contrary to Seller’s written
instructions or manuals; (d) to any damage resulting from
improper service or a lack of proper maintenance; or (e) to
any damage resulting from failure to comply strictly with
these Installation and Servicing Instructions in all respects.

LIMITATIONS OF WARRANTY:

Other than as stated herein or in any other warranty of
Seller, there are no other warranties of any kind whatso­ever, express or implied, and all other express and all
implied warranties of merchantability and/or fitness for any
particular purpose are hereby specifically disclaimed.

EXCLUSIVE REMEDY:

The sole and exclusive remedy for any loss, damage or
liability, or otherwise, is limited to the obligation of Seller to
repair or replace parts, at its factory, of any product owned
by original buyer and returned to the Seller’s factory within
one year after invoice, with transportation charges prepaid,
which examination reveals to have been defective. Under no
circumstances shall Seller be liable for any loss, damage,
cost, expenses, or incidental or consequential damages of
any kind, in connection with the sale, installation, use, main­tenance, or repair of any Product.

BUYER RESPONSIBLE FOR DATA:

Seller and its representative may furnish Buyer, upon
Buyer’s request, data relating to the function and use of
Products. Seller shall not be liable for loss, damage, cost,
expenses or incidental or consequential damages of any
kind, sustained directly or indirectly, by any person, or to any
property, if Buyer adopts and uses such data in whole or in
part.

LIMITATIONS ON AUTHORITY OF REPRESENTATIVES:

No representative of Seller, other than an Executive
Officer, has authority to change or extend these provisions.
Changes or extension shall be binding only if confirmed in
writing by Seller’s duly authorized Executive Officer.
