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 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.
Thin sheet metal parts, including the aluminum
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.
1.1 Manpower Requirements
To prevent personal injury and damage to the heater,
two persons will be required for installation.
SECTION 1: HEATER SAFETY

TF-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• 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, ventilation and distribution in accordance with local
codes.
• To safely and adequately install heater using
materials with a minimal working load of 75 lbs
(33 kg).
2.1 Wall Tag
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
independent distributor
to obtain the wall tag. 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
BZC
Controller).
A copy of the wall tag (P/N 91037912) is illustrated on
the back cover. For an immediate solution, you may
affix this copy 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. See Page 3, Figure 1 through Page
6, Figure 10. Write the proper clearance dimensions
in permanent ink according to your model number
and configuration in the open spaces on the tag.
2.2 Corrosive Chemicals
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
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 life span 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: CRITICAL CONSIDERATIONS
3.1 Required Clearances to Combustibles
Clearances are the required distances that
combustible objects must be away from the heater to
prevent serious fire hazards. 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 the
burner of the heater and on Page 3, Figure 1 through
Page 6, Figure 10 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 gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors 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 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
SECTION 3: CRITICAL CONSIDERATIONS
WARNING
Fire Hazard
Some objects will catch fire or explode when placed
close to heater.
Keep all flammable objects, liquids and vapors the
required clearances to combustibles away from heater.
Failure to follow these instructions can result in death,
injury or property damage.
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 Fire Marshal, Fire Insurance Carrier
or other authorities for approval of proposed
installation when there is a possibility of exposure
to combustible airborne materials or vapors.
• Hang heater in accordance to the minimum suspension requirements on Page 14, Figure 12.
• 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: 1. All dimensions are from the surfaces of all tubes, couplings and elbows.
2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream
from where the burner and burner tube connect.
