1. Description
Read all instructions before installing and using the heater.
1. The OK3 radiant heaters are suitable for comfort heating
use in non-hazardous areas protected from rain, snow
or splashing, where heating element temperatures
in excess of 750°C (1382°F) will not present the risk of
fire or explosion. The heater does not present a safety
hazard when it is installed, operated and maintained in
accordance with these instructions.
2. The OK3 heater has two U-shaped metal sheath heating
elements factory interconnected in series or parallel
depending on voltage. Never change heaters which have
been factory series connected to a parallel connection.
3. Minimum space clearances from combustibles, when
heaters are horizontally mounted and installed, as listed
in Table 1.
