WARNING
GAS CONNECTION
Improper installation, connection, or adjustment can result in property damages, toxic
gases, asphyxiation, injury and death. Using an approved flexible gas connector in the
USA and Rubber Type 1 hose connector in Canada, the gas supply to the heater must be
connected and tested in accordance with all local, state, provincial, and national codes
(ANSI Z223.1/NFPA 54 in USA: B149.1 in Canada) and as indicated in the manual.
WARNING
VENTING
Inadequate venting of a heater may result in asphyxiation, carbon monoxide poisoning,
injury or death. The heater may be directly or indirectly vented from the space. Venting
must be in accordance with all local, state, provincial, and national codes (ANSI
Z223.1/NFPA 54 in USA; B149.1 in Canada) and as indicated in this manual.
WARNING
START-UP SMOKE CONDITION
During start up, the heating of material coatings used in the production process of tubes
and reflectors will create smoke during the initial period of operation. This condition is
normal and temporary. Ensure that there is sufficient ventilation to adequately clear any
smoke from the space. Notify site and safety personnel to ensure that alarm systems are
not unduly activated.
WARNING
CLEARANCES TO COMBUSTIBLES
The stated clearance to combustibles represents a surface temperature of 90 degree
Fahrenheit (32 degrees Celsius) above room temperature. Building material with a low
heat tolerance may be subject to degradation of lower temperatures. It is the installer’s
responsibility to assure that adjacent material are not subject to degradation.
A warning statement that an overhead heater should be installed so that the minimum
clearances marked on the heater will be maintained from vehicles parked below the
heater
Location of flammable or explosive objects, liquids or vapours close to the heater may
cause fire or explosion and result in property damage, injury or death. Do not use, store
or locate flammable or explosive objects, liquids or vapours in proximity of the heater.
The clearance to combustible material represents the minimum distance that must be
maintained between the outer heater surface and a nearby surface. The stated clearance to
combustible represents a surface temperature of 90 degrees F (50 degrees C) above room
temperature. It is the installer's responsibility to ensure that building materials with a low
