Critical Considerations

The Vantage® HE 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 which has at least 2" (5 cm) of horizontal
travel for each burner in a straight run. Be sure the
suspension system is sufficiently flexible to
accommodate thermal expansion which occurs as the
system heats up (see Figure 15).
• Outdoor hanging: Chain should not be used when
installing the unit outdoors. Use a suspension system
which minimizes the lateral movement or swing which
might damage reflectors. See Figure 14b for further
details.
• Washbays: The VANTAGE® HE unit must not be
exposed to the direct spray from a pressure washer.
• Provide access to burners for servicing, preferably on
both sides, above, and behind for burner removal.
• Be sure the heater has a downward pitch of 1/2" per
20 ft. (1 cm per 6 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.
• A minimum of 10 ft. (3 m) on HE-60/80 and a
minimum of 15 ft. (4.6 m) on HE-100/125/150/175 is
required between the burner and the first elbow.

Installation Procedure

Take maximum advantage of the building's 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. Begin the installation at the
most critical dimension. This could save time. 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 ft. (1 cm per 6 m) away from
burner.
Outdoor Mounting: The VANTAGE
stationary mounting in all situations and should not be
suspended from any structure which may become mobile
or from any organic structures such as a tree.
Clearances to combustibles must be maintained in all
cases; do not install heaters in a location such as a
parking area, where a vehicle with a painted or non-
metallic upper surface, may be parked within the
clearances to combustibles.
The bottom of the combustion air inlet shall not be less
than 12" (30 cm) above a surface which could support
snow, ice, or debris.
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.
• Check to see that all material and equipment is on the
job before starting installation.
• Allow for thermal expansion of the hot tube.
• Install the gas connector only as shown in instructions
(see Figure 27).
• Have slip joints where required between reflectors to
keep them from buckling or coming apart.
