ROBERTS-GORDON SECTION 1: WARNINGS pg 1
WARNING
FIRE OR EXPLOSION HAZARD
Failure to follow these instructions will result in
personal injury or property damage:
1. Read this manual carefully before installing or
servicing this equipment. Improper installation,
service or maintenance will result in death, injury or
property damage.
2. Check clearances given on the outside of each burner to
make sure the product is suitable for your application.
3. Installer must be a trained, experienced service
technician or representative.
4. All service must be performed only by a trained
service technician or representative.
5. After installation is complete, check product operation
as provided in these instructions.
Combustibles: Failure to maintain the specified
minimum clearances to combustibles will result in a
serious fire hazard. Do not locate flammable or
combustible materials within this distance. Signs should
be posted in storage areas to specify maximum stacking
height to maintain required clearances to combustibles.
Do not locate in hazardous atmospheres containing
flammable vapors or combustible dust. United States:
Installations in public garages or airplane hangars are
permitted when in accordance with ANSI Z83.6 and
NFPA-409 and 88 Codes. Canada: Installation in public
garages is permitted when in accordance with CAN/CGA
B.149.1 or .2. Installation in airplane hangars is
permitted when in accordance with the requirements of
the enforcing agency.
Vehicles: Minimum clearances must be maintained from
vehicles parked below the heater. Ensure that adequate
clearance is maintained where vehicle lifts are in
operation.
Gas Connection: There is an expansion of the radiant
pipe with each firing cycle, and 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 strictly in accordance with Figure
25 of these instructions.
Ignition: This appliance does not have a pilot. It is
equipped with an ignition device which automatically
lights the burner. Do not try to light the burner with a
match.
Mechanical Hazard–Suspension: Use appropriate
suspension hardware, beam clamps (rod or perforated
strap) and turnbuckles at predetermined locations. The
weight and normal movement of the heating system may
cause support failure if the following minimum suspension
requirements are not met: distance between supports must
be 10 ft. (3 m) or less; chain must be galvanized straight link
welded chain, 3/16” or larger in Diameter, with a working
load limit of a mimimum of 750 lbs. Failure of the supports
will cause death, injury or property damage.
Failure to follow these instructions will result in
personal injury or property damage:
Do not use in an atmosphere containing halogenated
hydrocarbons or other corrosive chemicals. Some
compounds in the air can be drawn into the equipment
and can cause an accelerated rate of corrosion of some
parts of the heat exchanger. The use of such chemical
compounds in or near the enclosure should be avoided
where a longer life of the burner, tubing and other parts
is desirable.
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. Figure 2 gives
minimum acceptable clearances to combustibles.
If the building has a slight negative pressure or
contaminants are present in the air, an outside
combustion air supply to the heaters is strongly
recommended.
Failure to follow these instructions will result in
damage to the system components:
Do not high pressure test the gas piping with the burners
connected. Failure to follow this procedure will exceed
the pressure rating of burner gas controls and this will
require complete replacement of these parts.
This heater is designed for heating nonresidential indoor
spaces. These instructions, the layout drawing, local
codes and ordinances, and applicable standards that
apply to gas piping, electrical wiring, venting, etc., must
be thoroughly understood before proceeding with the
installation
WARNING
CAUTION
Improper installation, adjustment, alteration,
service or maintenance will result in death, injury
or property damage. Read the installation,
operation and service manual thoroughly before
installing or servicing this equipment. For
assistance or additional information, consult a
qualified installer, service agency or your gas
supplier.
WARNING
FOR YOUR SAFETY:
Do not store or use gasoline or other flammable objects,
liquids or vapors in the vicinity of this heater or any other
appliance.
