HAZARD SUMMARY

Hazard Identification
Warnings and Cautions appear at appropriate sections throughout this manual. Read these carefully.
mWARNING:
mCAUTION:
CAUTION:
The following safety precautions apply to the instal-
lation, operation, and maintenance of the equipment
described by this technical manual.
mWARNING:
Any unauthorized modification of this equipment
shall void the warranty.
mWARNING:
Only qualified personnel should attempt instal-
lation, service, and repair of this equipment. Use
extreme caution and observe safety regulations at
all times.
mWARNING:
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 build-
ing, (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.
