must be done by a contractor qualified in the
CAUTION
installation and service of gas-fired heating equipment.
Do not use heater in an area containing corrosive
chemicals.
Read this manual carefully before installation,
operation, or service of this equipment.
Avoid the use of corrosive chemicals to ensure a
longer life of the burner, tubing and other parts.
Failure to follow these instructions can result in death,
injury or property damage.
Failure to follow these instructions can result in
property damage.
This heater is designed for heating non-residential indoor Roberts-Gordon 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 sub-
contractor, or the owner identifies the presence of
combustible materials or halogenated hydrocarbons*
anywhere in the premises.
spaces. Do not install in residential spaces. These
instructions,layouts,AS5601/AG 601,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.
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 recommends the
installer contact a local building inspector or Fire
Marshal for guidance.
* Halogenated Hydrocarbons are a family of chemical com-
pounds characterized by the presence of halogen elements
(flourine, 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.
• To use the information given in a layout drawing and
in the manual together with the cited codes and
regulations to perform the installation.
2.3 National Standards and Applicable Codes
All Appliances must be installed in accordance with the
latest revision of AS5601/AG601 and other relevant
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.
• To install the heater in accordance with the Clear-
ances 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 any-
thing from heater.
2.1 Low Level User Instructions
In all situations, clearances to combustibles must be
maintained. Failure to observe clearances to
combustibles can result in death, severe injury or
property damage. 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.

Failure to follow these

3.1 Minimum Required Clearances to Combustibles
Clearances are the required distances that combustible
objects must be kept away from the heater to prevent
serious fire hazards. Combustibles are materials, which
may catch on fire and include common items such as
wood, paper, rubber, fabric, etc. Maintain clearances to
combustibles at all times for your safety.
Clearances for all heater models are located on Page 4,
Figure 2 through Page 7, Figure 15 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.
• Maintain clearances from heat sensitive material,
equipment and workstations.
• Maintain clearances from vehicles parked below the
heater.
• Maintain clearances from swinging doors, overhead
cranes, vehicle lifts, partitions, storage racks, hoists,
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 combusti-
bles. 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 suspen-
sion requirements on Page 9, Section 4.6 through
Page 9, Section 4.8.
• 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.

NOTE:- Factory recommended mounting heights are listed above as a guideline. If infra-red heaters are
mounted too low, they may result in heat discomfort. It is generally recommended to observe the
recommended mounting heights to optimize comfort conditions. However, certain applications such as spot
heating, freeze protection, outdoor patio heating or very high ceilings may result in the heaters being
mounted outside of the factory recommended mounting heights. Clearances to combustibles must always be
maintained.

SECTION 7: LINEAR HEATER INSTALLATION
SECTION 7: LINEAR HEATER INSTALLATION
The figures in this section provide a general overview of
component placement in a BLACKHEAT® Linear
system. The location of some components
such as supports and couplings is crucial for proper
installation. Assemble the heater components as shown
on Page 14, Figure 17.
For optional reflector configurations for Linear heaters
See Page 4, Figure 2 through Page 5, Figure 8. Install
appropriate suspension hardware, beam clamps, chain or
rod at predetermined locations. Adjustments of chain
length will provide uniform pitch.
