MORTEX PRODUCTS INC 501 TERMINAL RD FORT WORTH, TX 76106 Page 6
General Homeowner/User Information
1. Refer to the furnace rating plate for the furnace model number
and specications for safe operation.
2. Provide clearance for service access to the burner
compartment, control box, and the blower compartment.
3. Failure to carefully read and follow all of the instructions in
this manual can result in malfunction of the furnace, property
damage, personal injury, or death.
4. If the furnace is installed in a residential garage, it must be
installed so the burner is located not less than 18 inches above
the oor and the furnace must be located or protected to avoid
physical damage by vehicles.
The Service Technician
A qualied service technician is required to perform any service
or repairs on the furnace. If the furnace gives any indication
of improper operation, call the service technician. The service
technician is allowed to perform the normal routine care of your
furnace as well as service and repairs and can detect potential
problems and make corrections before trouble develops.
Preventative maintenance of this type will allow the furnace to
operate with minimal concerns to the homeowner or users and
will add years of reliable comfort.
Warranty and Responsibilities
It is the responsibility of the homeowner to make certain the
furnace has been properly installed and adjusted to operate
properly.
The manufacturer warrants the furnace to be free from defects
in material or workmanship for a stated time in the warranty
agreement. The manufacturer will not be responsible for any
repair costs to correct problems due to improper setup, improper
installation, improper furnace adjustments, adding parts that
are not listed by the manufacturer for use with the furnace, and
improper operating procedures by the homeowner or users.
Specic examples of service calls which will be excluded from
warranty reimbursement are:
1. Correcting faulty duct work due to too few ducts or ducts that
are too small to provide proper air ow through the furnace.
2. Correcting wiring problems in the electrical circuit to the
furnace.
3. Resetting circuit breakers or on/o switches used for servicing.
4. Furnace problems caused by installation and operation of any
air conditioning unit, heat pump, or other air quality devise
which is not approved for use with this furnace.
5. Adjusting or calibrating the thermostat.
6. Problems caused by construction debris which has fallen into
the furnace.
7. Replacement of fuses.
8. Problems caused by dirty air lters.
9. Problems caused by restrictions in the return or supply air ow
causing low air ow.
The home owner should establish a thorough understanding of
these responsibilities with the installer or service company to
prevent misunderstandings at a later time.
While Homeowner or User is Away From Home
The furnace is equipped with safety shuto devices which will
shut o the gas burner in case of a malfunction. For this reason, it
is never practical to assume the furnace will operate unattended
for a long period of time.
If the homeowner or user is planning to be away from home for
a long period of time, someone should be asked to check on the
home every day especially when the outside temperature may fall
below 35°F to ensure the furnace is operating properly to prevent
water pipes from freezing.
When to Call For Service Assistance
Very often time can be saved if the service agency is given
information about a furnace problem ahead of time. This will
enable the service agency to possibly identify the source of
the problem prior to the service call and determine the specic
replacement components that may be required so the service
agency can arrive with the parts to x the problem.

SECTION 3: STARTUP AND SHUTDOWN
INSTRUCTIONS
Safety Information
Read the safety instructions below before trying to start the
furnace.
1. This furnace does not have a pilot light. It is equipped with an
ignition device which automatically lights the burner. Do not
try to light the burner by hand.
2. Before starting the furnace, smell around the furnace area for
gas. Be sure to smell next to the oor because some gases are
heavier than air and will settle on the oor.
3. Only use a nger to push the gas control switch to the “ON”
position. Never use tools. If the switch will not operate by hand,
don’t try to repair it. Call a qualied service technician. Force or
attempted repair may result in a re or explosion.
4. Do not use this furnace if any part has been under water.
Immediately call a qualied service technician to inspect the
furnace and replace parts and controls that have been under
water.
