SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• To ensure the system is designed in accordance
with the parameters of the CORAYVAC®design
manual (P/N128500UK).
• To install the heater, as well as the gas and elec-
trical supplies, in accordance with applicable
specifications and codes. Roberts-Gordon rec-
ommends 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 local and
national codes 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.
•Tonever 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 combus-
tion and ventilation in accordance with local and
national codes.
• To safely and adequately install heater using
materials with a minimum working load of 33 kg
(75 lbs).
• To ensure the heater is placed in a 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 belowheater to maintain required
clearances to combustibles. Minimum clearances
must be maintained from vehicles parked belowthe
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 construc-
tion,etc.
A laminated wall tag is available for the CORAYVAC®
heater as a permanent reminder of the safety
instructions and the importance of the required
clearances to combustibles. Please contact Rob-
erts-Gordon or your ROBERTS GORDON®indepen-
dent 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
CORAYVAC®heater (e.g. thermostat or Controller).
A copy of the wall tag (P/N91037912) is illustrated
on the back cover. This copy of the wall tag must be
affixed on the wall near the heater. Knowyour model
number and installed configuration. Model number
and installed configuration are found on the burner
and in the Installation, Operation and Service Man-
ual. Write the largest clearance dimensions with per-
manent ink according to your model number and
configuration in the open spaces on the tag. See
Page 6, Section 3.2.
2.2 Corrosive Chemicals
Roberts-Gordon Europe Limted cannot be responsi-
ble 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 iden-
tifies the presence of combustible materials, corro-
sive 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 com-
pounds 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 compo-
nents 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
local and national codes. This refers also to the elec-
tric, gas and venting installation. Note: Additional
standards for installations in Public Garages, Aircraft
Hangars, etc. may be applicable.
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: CLEARANCES TO COMBUSTIBLES
5 of 54
SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 Required Clearances to Combustibles
Clearances are the required distances that combus-
tible objects must be away from the heater to pre-
vent serious fire hazards. Combustibles are
materials, which may catch on fire and include com-
mon 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 7 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 clear-
ances are maintained. Read and followthe safety
guidelines below:
• Keep gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors away from this heater or any other
appliance.
• The stated clearances to combustibles represents
a surface temperature of 32°C above room tem-
perature. Building materials with a lowheat toler-
ance (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,
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 vapours.
• Hang heater in accordance to the minimum sus-
pension requirements
on Page 14, Figure 11 .
• If the radiant tubes must pass through the build-
ing structure, be sure that adequate sleeving and
fire stop is installed to prevent scorching and/or
fire hazard
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.
