CTH2V-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 sus-
pend anything from heater.
•To ensure there is adequate air circulation around
the heater and to supply air for combu
stion, 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).
• 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 5, Figure 3 through Page
8, 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
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.
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: 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 combusti-
ble 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 clear-
ances to combustibles at all times for safety.
Clearances for all heater models are located on the
burner of the heater and on Page 5, Figure 3 through
Page 8, Figure 12 in this manual. Check the clear-
ances 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 represents
a surface temperature of 90° F (32°C) above room
temperature. Building materials with a low heat tol-
erance (such as plastics, vinyl siding, canvas, triply, 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.
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.
SECTION 3: CLEARANCES TO COMBUSTIBLES
• 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 sus-
pension requirements
• 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.
