distances must be observed to insure proper operation.
A. Six (6”) inches from bottom of heater to floor.
B. One (1”) inch from wall or other obstruction to the right or
left side of heater.
3. Do not mount heater in a recess, since such mounting interferes
with free air circulation, increases temperatures and prevents
proper thermostat operation.

OPERATION
DANGER: Hazard of Fire. Keep combustible materi-
als and temperature sensitive fabrics at least 4”
away from front of cover or above cover.
WARNING: Users should install adequate back-up
controls and safety devices with their electric
heating equipment. Where the consequences of
failure may be severe, back-up controls are essential. Although the safety of the installation is the
responsibility of the user, Chromalox will be glad to
make equipment recommendations.
MAINTENANCE
WARNING: Hazard of Severe Shock. Disconnect all
power to heater before servicing or replacing
heaters.
1. Following long periods of idleness, heater should be vacuumed
before start-up, to remove accumulated combustible particles
which will incinerate causing smoking and consequent wall
discoloration.
2. If heater is located in areas of heavy traffic, furnish suitable
heater guard (wall mounted pipe rail in front of case, for example) to prevent damage to heater.
