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.
SECTION 1: HEATER SAFETY
A wall tag is supplied with the BLACKHEAT® heater as a
permanent reminder of the safety instructions and the
importance of the minimum required clearances to
combustibles. A copy of the wall tag is illustrated on Page
2, Figure 1. Peel off the backing of the adhesive strips on
the rear surface of the tag and position the tag on a wall
near the BLACKHEAT® heater (e.g. thermostat or
ROBERTS GORDON
®
BZC Microprocessor Controller).
WARNING
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 service of this equipment.
Failure to follow these instructions can result in death,
injury or property damage.
This heater is designed for heating non-residential indoor
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.
• 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.
2.2 Halogenated Hydrocarbons
CAUTION
Do not use heater in an area containing corrosive
chemicals.
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
property damage.
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 subcontractor, or the owner identifies the presence of
combustible materials or halogenated hydrocarbons*
anywhere in the premises.
* Halogenated Hydrocarbons are a family of chemical compounds 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.
2.3 National Standards and Applicable Codes
All Appliances must be installed in accordance with the
latest revision of AS5601/AG 601 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.
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.

SECTION 3: CRITICAL CONSIDERATIONS
WARNING
SECTION 3: CRITICAL CONSIDERATIONS
Fire Hazard
Some objects will catch fire
or explode when placed
close to heater.
Keep all flammable objects,
liquids and vapors the
minimum required
clearances to combustibles
away from heater.
Failure to follow these
instructions can result in
death or injury.
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 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 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.
Burn Hazard
Keep all persons,
especially children, away
from heater.
Do not touch any part of
the heater.
Heater is very hot.
Failure to follow these
instructions can result in
severe injury.
