EV INSTALLATION MANUAL ROBERTS-GORDONpg 4
Critical Considerations
The EV-Series is a suspended heater. Therefore, its
stability, flexibility, and safety are very important. Before
starting installation, be sure the system can meet the
following requirements:
• Maintain specified clearances to combustibles, and
safe distance from heat-sensitive material, equipment
and work stations.
• Provide a suspension with vertical length of chain or
swinging rod. Be sure the suspension system is
sufficiently flexible to accommodate thermal expansion
which occurs as the system heats up (see Figure 15).
• Provide access to burners for servicing, preferably on
both sides, above, and behind for burner removal.
• Provide for a minimum of 24” (61 cm) of clearance
between burners and building walls. Always observe
minimum clearances to combustibles.
• Be sure the heater has a downward pitch of 1/2" per 20'
(1 cm per 5 m) away from the burner.
• Provide signs in storage areas to specify maximum
stacking height to maintain required clearances to
combustibles.
• Plan location of supports. Locate a support near all
elbows.
Installation Procedure
Take maximum advantage of the building upper structure,
beams, joists, purlins, etc., from which to suspend the
heater. There is no unique sequence for installation of the
tubing. On-site observation will usually reveal a logical
sequence. Watch for swinging doors, overhead cranes,
car lifts, etc. Reflectors and tubing can be installed as you
move along. Carefully adjust system pitch at each
position to level the heater. Pitch down 1/2" per 20' (1 cm
per 5 m ) away from burner.
Do Not:
• Pressure test the gas line using high pressure (greater
than 1/2 PSIG) without closing the high-pressure
shutoff cocks. Failure to do so will result in damage to
the burners.
Do:
• Familiarize yourself with local and national codes.
• Develop a planned procedure which will conserve
material and labor on the job site.
• Check to see that all material and equipment is on the
job site before starting installation.
• Allow for thermal expansion of the hot tube.
• Install the gas connector only as shown in instructions.
(See Figure 25)
• Have slip joints where required between reflectors to
keep them from buckling or coming apart.
• Provide one square inch of free air opening to each
1,000 BTU/hr of heater input but not less than 100
square inches in enclosed spaces. (6.5 cm
2
per 250
kcal/hr). One opening should be within 12 inches (30
cm) of the top and one within 12 inches (30 cm) of the
bottom of the enclosure.
WARNING
Several steps are involved in the installation of the heater.
Do not attempt to operate the heater until all steps of the
installation have been accomplished.
Failure to follow these instructions will result in death,
injury or property damage.
WARNING
Fire Hazard
Some objects will catch fire or explode when placed close to
heater.
Keep all flammable objects, liquids and vapors the required
safe distances away from heater.
Failure to follow these instructions will result in death, injury
or property damage.
Risque d’incen
Certains objets placés près du radiateur peuvent s’enflammer
ou exploser.
Tenir tous les objets, liquides et vapeurs inflammables à la
distance de sécurité requise du radiateur.
Le non-respect de ces consignes peut causer mort, blessures
ou dommage matériel.
