INSTALLATION IN COMMERCIAL GARAGES AND PARKING
STRUCTURES
Low intensity heaters are suitable for use in commercial garages when installed in accordance
with the latest edition of the Standard for Parking Structures, ANSI/NFPA 88A, or the Standard
for Repair Garages ANSI/NFPA No. 88B, or the Canadian Natural Gas and Propane Installation
Code, B149.1
WARNING
INSTALLATIONS OTHER THAN SPACE HEATING
Use for process or other applications that are not space heating will void the products
warranty. Process application requires field inspection and/or certification by local
authorities having jurisdiction.
IMPORTANT
Single or multiple heater placements must be such that continuous operation of heater(s)
will not cause combustible material or materials in storage to reach a temperature in
excess of ambient temperature plus 90 degrees Fahrenheit (50 degrees Celsius).
It is the installer’s responsibility to ensure that building materials with a low heat
tolerance, which may degrade at lower temperatures, are protected to prevent
degradation. Refer to Clearance to Combustibles information in these installation
instructions.
GENERAL INSTALLATION PROCEDURE
PRE-INSTALLATION SURVEY
It is recommended that a full heating design, including a heat loss calculation be
conducted. Heater sizing and placement must consider available mounting height, sources
of heat loss, and clearances to combustibles with respect to stored material, moveable
objects (cranes, vehicles, lifts, overhead doors, etc) sprinkler systems, and other
obstructions on the site. Consideration must also be given to vent / duct placement and
the allowable combined lengths of vent and duct.
1.
Carefully survey the area to be heated and place the burner and combustion
chamber in the coldest area if possible.
2.
The heater shall be hung in such a fashion so as to conform with the clearances to
combustibles described on the name plate.
3.
Clearances to combustibles must be maintained from vehicles parked below.
4.
Adequate clearances must be maintained for installation in public garages and
airplane hangar.
5.
It should be located with respect to building construction and equipment, so as to
provide sufficient clearances and accessibility for servicing.
6.
The installation must comply with local codes and CAN/CGA B-149 in Canada or
the National Fuel Gas codes ANSI Z 223.1 in the United States
