GENERAL

FIRE/EXPLOSION HAZARD. This heater is not intend- ed for use in hazardous atmospheres where flamma- ble vapors, gases, liquids or other combustible atmos- pheres are present as defined in the National Electrical Code. Failure to comply can result in per- sonal injury or property damage

The NWHO(F)-18 series is a general purpose regular and fuel oil solution circulation heater intended for use indoors.

The steel-sheathed tubular elements are centered in a steel heating chamber and sealed into a removable steel flange. The assembly is surrounded by insulation and a sheet metal jacket.

Depending upon the order specifications, the NWHO(F)-18 may or may not be factory equipped with an AR or other Chromalox thermostat. Such thermostats function to control outlet temperatures and to limit internal temperatures under abnormal flow conditions. These controls do not fail-safe.

The system designer is responsible for the safety of this equipment and should install adequate back-up controls and safety devices with their electric heating equipment. Where the consequences of failure could result in personal injury or property damage, back-up controls are essential.
