SECTION 2: Planning
The following codes and instructions should be followed when
planning the installation of this JET heater. In addition to these
instructions, the warnings must be carefully adhered to since
improper installation may lead to property damage, injury, or
death.
National Standards and Applicable
Codes
Gas Codes:
• T he type of gas appearing on the nameplate must be the
type of gas used. Installation must comply with local codes
and recommendations of the local gas company, and the
National Fuel Gas Code, ANSI Z223.1 – latest revision, (same
as NFPA Bulletin 54) (the Natural Gas and Propane Installation
Code, CSA B149.1) Canada only.
• Clearance between the heater and its vent and adjacent
combustible material (which is part of the building or its
contents) shall be maintained to conform with the Standard
for Installation of Gas Appliances and Gas Piping, NFPA-54
/ ANSI Z223.1 – latest revision, National Fuel Gas Code (the
Natural Gas and Propane Installation Code, CSA B149.1)
Canada only.
Hazardous Locations:
Where there is the possibility of exposure to combustible
airborne material or vapor, consult the local Fire Marshal,
the fire insurance carrier or other authorities for approval of
the proposed installation.
Critical Considerations
This JET model 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 the heat-sensitive material, equipment and
work stations.
• The stated clearances to combustibles represent a surface
temperature of 90°F (30°C) above room temperature.
Building materials with low heat tolerance (such as plastic,
vinyl siding, canvas, etc.) may be subject to degradation at
lower temperatures. It is the installers responsibility to assure
that adjacent materials are protected from degradation.
• Provide access to burners for servicing, preferable on both
sides, above and behind the burner for removal.
• Always observe minimum clearances to combustibles located
on page 4.
• Plan location supports (see Figure 2A-B starting on page 6).
• The installation must conform with local building codes or
in the absence of local codes, with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 (the Natural Gas and Propane
Installation Code, CSA B149.1) Canada only.
• If an external electrical source is utilized, the heater, when
installed, must be electrically grounded in accordance with
the National Electrical Code, ANSI/ NFPA 70 or current
Canadian Electrical Code, CSA C22.1.

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. Begin the
installation at the most critical dimension. Reflectors and tubing
can be installed as you move along. Carefully adjust system pitch
at each position to level the heater. Pitch down one-half inch in
20 feet (away from burner).
DON'T Pressure test the gas line using high pressure (greater
than ½ 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.
D evelop a planned procedure which will conserve
material and labor on the job.
C heck to see that all material and equipment is on the
job before starting installation.
A llow for thermal expansion of the tubes.
I nstall the gas connector only as shown in instructions
(see Figure 14 & 15 on page 1 1).
Use self tapping screws where reflectors overlap to
assure that they don't come apart.
Attach reflector retention wire to burner box or chain
suspending burner box. The wire comes attached to one
of the reflectors. See intructions in tube set for details.
P rovide 1 sq. inch of free air opening to each 1,000 BTU/
hr. of heater input (but not less than 100 sq. inches) in
enclosed spaces. One opening should be within 12 inches
of the top and one within 12 inches of the bottom of the
enclosure.
