SECTION 1: HEATER SAFETY
Yo ur 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
Figure 1: Side and Back Panel Label Placement
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.
For additional copies of the Installation, Operation
andService Manual, please contact Roberts-Gordon LLC.
1.1 Manpower Requirements
To p r e vent personal injury and damage to the heater, two
persons will be required for installation.

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 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 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,
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.
ventilation
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 or ROBERTS GORDON
Controller).
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.

2.2 Corrosive Chemicals
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, 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.
®
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,
which 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 17 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 w
(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, stor-
age 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 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.
ith a low heat tolerance
• 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 73, Section 18.6
through Section 18.8.
• 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.
