Installation, Operation, Maintenance and Parts Manual
Detroit Radiant Products Company Check the AGA rating label on the heater to verify
model number. Check and maintain the attached
minimum clearance to combustibles label and the
proper gas to be used. Check all labels on the
heater to verify proper mounting. The installation of this heater must conform with
local building codes or, in the absence of local
codes, with the National Fuel Gas Code, ANSI
Z223.1-1999 (NFPA 54-current edition). The installation of this heater in public garages
must conform with the Standard for Parking
Structures, ANSI / NFPA 88A-current edition: or
the Standard for Repair Garages, ANSI / NFPA
88B-current edition, and must be at least 8 ft.
above the floor while maintaining all clearances
to combustibles. The installation of this heater in aircraft hangars
must conform to the Standard for Aircraft
Hangars, ANSI / NFPA 409-current edition. The
heater must be installed at least 10 ft. above the
upper wing surfaces and engine enclosures of
the highest aircraft which might be stored in the
hangar. In areas adjoining the aircraft storage
area, the heaters must be installed at least 8 ft.
above the floor. The heaters must be located in
areas where they will not be subject to contact by
aircraft, cranes, moveable scaffolding or other
objects.
CAUTION!
The following information should be reviewed
before installing this heater: If an external electrical source is utilized, the
heater must be electrically grounded in
accordance with the National Electrical Code,
ANSI / NFPA70-current edition. Under no circumstance is either the gas supply
line or the electrical supply line to the heater to
provide any assistance in the suspension of the
heater. The weight of the heater must be entirely
suspended from a permanent part of the building
structure having adequate load characteristics. Neither the gas supply line, electrical supply line
nor sprinkler heads shall be located in or near
the path or the flue products from the heater. This heater cannot be used in a building with an
uninsulated roof or condensation problems could
result. Where this heater is used, natural or mechanical
means shall be provided to supply and exhaust
at least 4.0(Nat.) or 4.5(LP) C.F.M. per 1000 BTU/
H input of the heaters rated input. Signs should be posted in storage areas to
specify maximum stacking height allowed in order
to maintain clearance to combustibles.
Clearance safety limit plaques (PLQ), available
from Detroit Radiant Products are recommended
for this purpose. 3

WARNING!
Failure to comply with the stated clearance to
combustibles could result in personal injury, death
and/or property damage.
WARNING!
This heater should be installed so that the minimum
clearance to vehicles, as marked on the heater, will
be maintained. If vehicle lifts are present, ensure
that these clearances will be maintained from the
highest raised vehicle.
NOTE: If the heater is mounted beneath a non-combustible surface a 24 in. minimum clearance
must be maintained from the top of the heater to prevent overheating the controls.

1.1 DESIGN
When positioning heater, keep in mind the clearance
to combustible materials, lights, sprinkler heads,
overhead doors, storage areas with stacked
materials, gas and electrical lines, parked vehicles,
cranes, etc. Refer to Figure 1.1 on page 3 for
minimum clearance to verify that a safe installation
condition exists.
In locations used for the storage of combustible
materials, signs shall be posted to specify the
maximum permissible stacking height to maintain
required clearances from the heater to the
combustibles.
1.2 LAYOUT
Perimeter mounting of these infrared heaters
provides for the most efficient installation. In Figure
1.5, the heaters are mounted around the perimeter
of the space to be heated. Refer to the Installation
Chart for the recommended distances on the models
being installed.
Buildings that require the rows of heaters to be farther
apart than the recommended distance in the
Installation Chart may need additional heaters placed
in the center of the space as in Figure 1-5.
Typical exhauster, air intake louver and thermostat
location is also shown on the sample buildings in
Figure 1.5.

Detroit Radiant Products Company Figures 2.1 and 2.2 illustrate the more commonly
used methods for heater mounting. Figure 2.1
shows the fastest and most economical method.
Some local codes or application conditions, such
as drafts that could cause units to swing,
stipulate that if flexible gas connectors are
used then the heaters must be rigidly mounted
(Figure 2.2) Heater must be level from side to side (see Figure
1.2 on pg. 3). The units must be mounted at a
20� to 35� angle from horizontal, so the controls
(or manifold end) are located at the lower end
(Figure 2.3-2.5). Gas and electrical lines must not
be located above the path of exhaust.
