protected against extreme dusty atmosphere and water
jets from all sides. Outside air supply and flue are
mandatory for this heater. The standard exhaust fans
mentioned in this manual do NOT have IP55 protection
and must be outside the wet environment. If the fan is to
be installed in the wet environment, a special IP54
protected fan must be used. Consult Roberts-Gordon
LLC for alternative exhaust fans. Optional stainless steel
burner box provides long life in the most corrosive
applications. Always ensure that the environment to be
heated is not of an explosive or flammable nature. For

more information, please consult your ROBERTS
GORDON

®

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 LLC 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.

• 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 ensure the heater is placed in an approved
application.

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 LLC 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).

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 LLC 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, 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.

The heater must not be operated in environmental
temperatures below 0° C.

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 3: CLEARANCE TO COMBUSTIBLES

5

SECTION 3: CLEARANCE 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
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 Page 6,
Figure 3 through Page 7, Figure 8 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°) above room tem-
perature. Building materials with a low heat tolerance
(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 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
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 5.

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.
