TF-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL
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
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 arou
the heater and to supply air for combustion, venti-
lation 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).
• To ensure the heater is placed in a approved
application.
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
®
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 6, Figure 3 through Page
4
9, Figure 12. 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
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
nd
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 P
ublic Garages, Aircraft Hangars,
etc. may be applicable.
Page 11
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.
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 6, Figure 3 through
Page 9, Figure 12 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 appli-
ance.
• The stated clearances to combustibles represent
a surface temperature of 90° F (50° C) above
room temperature. Building materials with a low
heat tolerance (su
vas, triply, etc.) may be subject to degradation at
lower temperatures. It is the installer’s responsibil-
ity 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,
storage 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 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
ch as plastics, vinyl siding, can-
on Page 17, Figure 14.
SECTION 3: CLEARANCES TO COMBUSTIBLES
• 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.

SECTION 6: SUGGESTED LAYOUTS
The following are suggested layouts for the heater. These layouts are effective in maximizing the heat pattern
and overall performance of the heater. All heaters can be common vented or individually vented (See Page
37, Section 9) depending on the building requirements. These are only suggested layouts. The heater can be
designed in various configurations provided they are in the guidelines of this manual. When designing a U-
Tube or Elbow configuration, the following rules must be adhered to:
• A minimum of 10' (3 m) of tubing on TF-120/160 and/or a minimum of 15' (4.5 m) of tubing on the TF-200/250/300/350/380 is required between the burner and the Elbow or U Tube.
• The design and installation must adhere to the rules and guidelines located in this manual (See Page 16, Section 7 and Page 37, Section 9).
• Review
venting options before selecting a layout.

2. The overlap at the first and second reflector is a slip overlap.
Thereafter, every third reflector joint is a slip overlap. A slip
overlap is achieved by either:
a.) both reflectors lay inside a hanger.
(No reflector support needed.)
b.) using a reflector support with
loose screws at the reflector
overlap.
3. The remaining reflector overlaps require a non-slip
overlap connection. To affix the reflectors together in
a non-slip overlap either:
a.) use reflector support and tight screws.
b.) if both reflectors lay inside a hanger, u-clips or

Step 7.6.1 Reflector, U-Clip and Reflector Support Installation
The pictorial drawings of the heater construction in
Section 7 are schematic only and provide a general
guideline of where hangers, reflector supports and
U-clips are to be installed.
To ensure proper expansion and contraction
movement of the reflectors, a combination of U-clips
and reflector supports are used. The positioning of
reflector supports and U-clips depends on the
individual installation. Use either pop rivets or sheet
metal screws instead of u-clips when installing end
caps and joint pieces in areas where impact and high
wind may be a factor. The following rules must be
observed.

design shall not incorporate backdraft flap.
FIGURE 22: Tube Termination
9.7 Horizontal Ventilation 4" (10 cm) Pipe
9.6 Length Requirements
The maximum vent length, where both tubes are
vented together is 45’ (13.7 m) of 6" (15 cm) diameter
duct. The maximum vent length, where both tubes
are vented individually is 45’ (13.7 m) of 4" (11 cm)
diameter duct, or 22.5’ (7 m) on each tube.
The maximum outside air s
upply duct length allowed
is 45’ (13.7 m) of either 4" (10 cm) or 5" (13 cm)
diameter, however the maximum length depends on
the venting arrangement used.
The total vent length, plus outside air duct length,
plus any extensions to minimum heat exchanger
lengths, cannot exceed 65' (19.8 m).
Vent length should be limited to less than 20' (6 m). If
using vent lengths greater than 20' (6 m),
condensation will form in the vent pipe. Insulation
and additional sealing measures (high temperature
silicone at all seams) are required. Optional heat
exchanger lengths are considered as vent length for
length determination.
Subtract 15' (4.6 m) of maximum allowed vent or duct
length per vent elbow if more than two are used.

SECTION 12: OPERATION AND MAINTENANCE
The heater is equipped with a dual direct spark
ignition system.
12.1 Sequence of Operation
1. Turn the thermostat up, the blower motor will energize.
2. When the motor approaches nominal running
RPM, the pressure switches will close and activate the ignition module.
3. After a 45 second purge period, the ignition module then opens the gas valve and energizes both spark igniters. The light will be illuminated at any time the gas valve is energized.
4. When both flames are established, the sparking sequence ceases.
5. If both flames are not established during the
ignition sequence, the ignition module closes
the gas valve and purge begins. The module will
try two additional times for ignition with purge
between trials. If ignition is not established dur-
ing either of these trials, the module will lock out.
6. After lock ou
must be re-set by turning down the thermostat
(disconnecting power) for five seconds, and raising it again to the desired temperature.
7. When the thermostat is satisfied, all power to the heater is shut off.
12.2 To Shut Off Heater
Set thermostat to lowest setting.

Turn OFF electric power to heater.
Turn OFF manual gas valve in the heater supply line.
12.3 To Start Heater
Turn gas valve and electric power OFF and wait five
minutes for unburned gases to vent from heater.
Turn ON main gas valve.
Turn ON electric power.
Set thermostat to desired temperature. Burner
should light automatically.
12.4 Pre-Season Maintenance and Annual Inspection
To e n s ure your safety and years of trouble-free
operation of the heating system, ser
inspections must be done by a contractor qualified in
the installation and service of gas-fired heating
equipment.
Turn off gas and electric supplies before performing
service or maintenance. Allow heater to cool before
servicing.
Before every heating season, a contractor qualified in
the installation and service of gas-fired heating
equipment must perform a thorough safety
inspection of the heater.
For best performance, the gas, electrical, thermostat
connections, tubing, venting, suspensions and
overall heater condition should be thoroughly
inspected.
NOTE: Gas flow and burner ignition are among the
first things that should be inspected. Please see
