HAZARD SUMMARY
Hazard Identification
Warnings and Cautions appear at appropriate sections throughout this manual. Read these carefully.
WARNING:
Indicates a potentially hazardous situation which could result in
death or serious injury.
CAUTION:
Indicates a potentially hazardous situation which may result in minor or
moderate injury. It may also be used to alert against
unsafe practices.
CAUTION:
Indicates a situation that may result in accidents with equipment or
property damage only.
The following safety precautions apply to the
installation, operation, and maintenance of the
equipment described by this technical manual.
WARNING:
Any unauthorized modification of this equipment
shall void the warranty.
WARNING:
Only qualified personnel should attempt
installation, service, and repair of this equipment.
Use extreme caution and observe safety
regulations at all times.
WARNING:
Recirculation of room air is not permitted.
Adequate building relief must be provided so as to not
over pressurize the building when the heating system
is operating at its rated capacity. It should be noted
that this can be accomplished by taking into account,
through standard engineering methods, the structure’s
designed infiltration rate, by providing properly sized
relief openings, or by interlocking a powered exhaust
system, or by a combination of these methods.
If the failure or malfunction of this heater creates
a hazard to other fuel burning equipment in the
building, (e.g. when the heater is providing the make-
up air to a boiler room), the unit is to be interlocked
to open inlet air dampers or other such devices.
If the heater is installed such that an inlet duct is
utilized, the duct system must be purged with at least
four air changes prior to an ignition attempt.
