TF-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL

SECTION 2: INSTALLER RESPONSIBILITY

The installer is responsible for the following:

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.

• To install the heater, as well as the gas and elec-

trical supplies, in accordance with applicable

specifications and codes. Roberts-Gordon recom-

mends the installer contact a local building

inspector or Fire Marshal for guidance.

2.2 Corrosive Chemicals

CAUTION

• 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.

Product Damage Hazard

Do not use heater in area containing

corrosive chemicals.

• To furnish all needed materials not furnished as

standard equipment.

• To plan location of supports.

Refer to appropriate Material Safety Data

Sheets (MSDS).

• To provide access to burners for servicing on all

sides for burner removal.

Failure to follow these instructions can result

in product damage.

• To provide the owner with a copy of this installa-

tion, operation and service manual.

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.

• 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, 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).

* Halogenated Hydrocarbons are a family of chemi-

cal compounds characterized by the presence of

halogen elements (fluorine, chlorine, bromine, etc.).

These compounds are frequently used in refriger-

ants, cleaning agents, solvents, etc. If these com-

pounds 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 com-

pounds is suspected. Warranty will be invalid if the

heater is exposed to halogenated hydrocarbons.

• 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

2.3 National Standards and Applicable Codes

your ROBERTS GORDON independent distributor

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.

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

Download from Www.Somanuals.com. All Manuals Search And Download.

SECTION 3: CLEARANCES TO COMBUSTIBLES

3.1 Required Clearances to Combustibles

WARNING

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.

Fire Hazard

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 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.

• Keep gasoline or other combustible materials

including flammable objects, liquids, dust or

vapors away from this heater or any other appli-

ance.

• 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.

• The stated clearances to combustibles represent

a surface temperature of 90° F (50° C) above

room temperature. Building materials with a low

heat tolerance (such as plastics, vinyl siding, can-

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 com-

bustibles. Signs must be posted adjacent to the

heater thermostat. In the absence of a thermo-

stat, 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 sus-

pension requirements on Page 1 7 , F igure 14.

and reflector supports are used. The positioning of

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.

Failure to follow these instructions can result

in injury.

8.1 U-Tube Configuration

The heaters are approved for optional U-Tube

configurations. This installation requires 1 or 2 U-

Tube packages depending on configuration desired.

Shown below is an example of a typical 80' (24 m) U-

Tube configuration. The U-Tube may be installed in

either a standard horizontal position or in an opposite

45° position as shown below. When designing a U-

Tube configuration, the following additional rules

must be adhered to:

• A minimum of 10' (3 m) on TF-120/160 and a min-

imum of 15' (4.5 m) on TF-200/250/300/ 350/380

is required between the burner and the U-Tube.

• The correct turbulator (See Page 24, Step 7 .5)

must be installed in the last standard section of

tube.

• The burner must never be operated in a tilted

position.

• When installed in a full 45° position, the burner

must be installed on the lower side.

• The heater must be properly supported at all loca-

tions. See Page 29, Figure 19.

SECTION 10: GAS PIPING

Install the gas hose as shown on Page 45, Figure 23.

The gas hose accommodates expansion of the

heating system and allows for easy installation and

service of the burner. A 90° pipe elbow (not supplied)

must be installed into the gas valve to ensure proper

orientation of the flex gas connector. Before

WARNING

connecting the burners to the supply system, verify

that all high pressure testing of the gas piping has

been completed.

There is an expansion of the tube with each firing

cycle, this will cause the burner to move with respect

to the gas line. This can cause a gas leak resulting in

an unsafe condition if the gas connection is not made

in strict accordance with Figure 23 on Page 45.

Meter and service must be large enough to handle all

the burners being installed plus any other connected

load. The gas line which feeds the system must be

large enough to supply the required gas with a

maximum pressure drop of 1/2" w.c. When gas piping

is not included in the layout drawing, the local gas

supplier will usually help in planning the gas piping.

Fire Hazard

Tighten gas hose fittings to connect gas

supply according to Figure 23.

Gas hose can crack when twisted.

Gas hose moves during normal operation.

Use only 36" (91 cm) long connector of 3/4"

nominal ID.

12.1 Sequence of Operation

1. Turn the thermostat up, the blower motor will

energize.

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.

2. When the motor approaches nominal running

RPM, the pressure switches will close and acti-

vate the ignition module.

module then opens the gas valve and energizes

both spark igniters. The light will be illuminated

at any time the gas valve is energized.

12.4 Pre-Season Maintenance and Annual

Inspection

To ensure your safety and years of trouble-free

operation of the heating system, service and annual

inspections must be done by a contractor qualified in

the installation and service of gas-fired heating

equipment.

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.

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.

6. After lock out has occurred, the ignition module

must be re-set by turning down the thermostat

(disconnecting power) for five seconds, and rais-

ing it again to the desired temperature.

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

Page 51, Section 12.5 for suggested items to

inspect.

7. When the thermostat is satisfied, all power to

the heater is shut off.
