HAZARD INTENSITY LEVELS
1. DANGER: Failure to comply will result in severe personal injury or death and/or property damage.
2. WARNING: Failure to comply could result in severe personal injury or death and/or property dam-
age.
3. CAUTION: Failure to comply could result in minor personal injury and/or property damage.
1A. Installation Codes
These units must be installed in accordance with local building codes.
In the absence of local codes, in the United States, the unit must be
installed in accordance with the National Fuel Gas Code ANSI Z223.1a
(latest edition). A Canadian installation must be in accordance with the
CAN/CGA B149.1 and B149.2 Installation Code for Gas Burning
Appliances and Equipment. These codes are available from CSA In-
formation Services, 1-800-463-6727. Local authorities having juris-
diction should be consulted before installation is made to verify local
codes and installation procedure requirements.
All electrical wiring must be in accordance with the National Electric
Code ANSI/NFPA NO. 70 (latest edition) or, in Canada, the Canadian
Electrical Code, part I-C.S.A. Standard C22.1.
The installing contractor must be familiar with all of the various re-
quirements and is responsible for installing this heater in compliance
with the applicable codes.
Special Installations --
Aircraft Hangars: In the United States, the heaters must be installed
in accordance with ANSI NFPA 409 (latest edition), Chapter 5. NFPA
Publications are available from the National Fire Protection Associa-
tion, Batterymarch Park, Quincy, MA 02269. In Canada, installation
in an aircraft hangar must comply with CAN/CGA-B149.2, Section
4.21. Both ANSI NFPA 409 and the CAN/CGA-B149.2 specify that
the heater shall not be located in an area of an aircraft hangar where it
may be subjected to physical damage by aircraft, cranes, moveable
scaffolding, or other objects.
NFPA 409 specifies a clearance of 10 feet to the bottom of the heater
from the highest surface of the wings or engine enclosures of the
highest aircraft which may be housed in the hangar. CAN/CGA B149.2
specifies that an infrared heater installed in an aircraft hangar be at least
10 ft (3m) above either the highest fuel storage compartment or the
highest engine enclosure of the highest aircraft which may occupy the
hangar. NFPA 409 and CAN/CGA B149.2 specify a minimum clear-
ance of eight feet from the floor to the heater in other sections, such as
offices, or shops, that communicate with the aircraft hangar.
Public Garages: In the United States, heaters installed in public ga-
rages must be in accordance with National Fire Protection Association
(NFPA) 88B (latest edition), Section 3-2.3. Overhead heaters must be
located not less than eight feet above the floor and installed in accor-
dance with the conditions of their approval. NFPA 88B requires the
following warning:
WARNING: Minimum clearance marked on the
heater must be maintained from vehicles parked
under the heater.
In Canada, in a garage, the minimum clearance from the bottom of an
infrared heater to the upper surface of the highest vehicle which may be
housed therein shall be 50 percent greater than the certified clearance,
and in no case less than eight feet (2.4m).
WARNING: These tubular radiant heaters DO
NOT qualify for explosion-proof installations.
WARNING: The installing contractor must be
certain that the area where the heater is being
installed does not contain corrosive or toxic fumes
or that elements in the atmosphere do not produce
corrosive or toxic fumes in the presence of an open
flame.
The chlorine atmosphere in enclosed swimming
pool areas may cause burner and tube corrosion if
the area is not ventilated. ASHRAE design guides
suggest a minimum of 5-6 air changes per hour.
The manufacturer recommends outside
combustion air. To provide outside combustion air,
Option DE2, Combustion Air Inlet Kit, must be
used.
1B. Warranty
Refer to limited warranty information on the warranty sheet in the "Owner's
Envelope".
2. Description/General
These radiant tubular heaters are low-intensity infrared heaters using a
power burner that fires into a 4" diameter steel tube, either 20, 30, 40, 50,
60, or 70 feet in length. The power burner is equipped with a blower for
supplying combustion air and a spark-to-pilot-to-main burner ignition sys-
tem. The highly emissive tubes are in 10-foot sections, and each section
has a polished reflector. The tube section attached to the burner is the
combustion chamber and all other sections are heat exchanger tubes with
the exhaust end heat exchanger tube being identified as the tail pipe. Op-
tional "L"-shaped, "U"-shaped, and 5-foot heat exchanger tubes are avail-
able to change the heater configuration to adapt to various applications.
Standard model heaters are designed to operate at full input rates of 50,000,
75,000, 100,000, 125,000, 150,000, 175,000, or 200,000 BTUH at alti-
tudes from 0 to 2000 ft elevation. High altitude model heaters are designed
to operate at full input rates of 50,000, 75,000, 100,000, 125,000, 150,000,
175,000, or 200,000 BTUH at altitudes from 2001 to 6000 ft elevation and
from 6001 to 8000 ft at full input rates from 50,000 to 175,000 BTUH.
Venting may be either vertical or horizontal. A vent cap must be used.
Install a vent cap supplied as Option CC1 or a fully-comparable, field-
supplied vent terminal cap such as a Type L Breidert Air-x-hauster
®
. (Type
L Air-x-hauster
®
is a trademark of The G. C. Breidert Company.) Dual
venting of two units is permissible when using an Optional Dual Vent Kit
(Option CC5). These heaters are also approved for operation without
outdoor venting.
Combustion air can either come from the heated space or be piped from
outside. Outside combustion air should be supplied (1) if the building
atmosphere has negative pressure; (2) if the building atmosphere is dirty or
dusty; (3) if the building atmosphere contains substances that will cause
toxic gas when combined with flame or flue products; or (4) if the heater is
being installed in a tightly closed room that does not provide required air
for combustion. Installation of an Optional Combustion Air Inlet Kit is
required to provide outside combustion air.
