This page contains various warnings and cautions found throughout this manual. Please
read and comply with the statements below.

: IF YOU DO NOT FOLLOW THE SAFETY PRECAUTIONS BELOW AND IN THIS MANUAL, A

FIRE OR EXPLOSION MAY RESULT CAUSING PROPERTY DAMAGE, PERSONAL INJURY, OR LOSS OF
LIFE.

: Property damage, personal injury, or loss of life could result from repair or service of

this furnace by anyone other than a qualified heating contractor. Only the routine maintenance
described in this manual may be performed by the user.

: To avoid injury from moving parts, shut off the power to the furnace before

removing blower compartment door.

: Keep furnace free and clear of combustible materials, gasoline, and other flammable

liquids and vapors.

: Do not use this furnace if any part has been under water. Immediately call a qualified

heating contractor to inspect the furnace and to replace any part of the control system and any gas
control which has been under water.

: If you suspect there is a problem with the furnace, its venting system or any other

related problem, immediately contact a qualified service agency.

: In the event your furnace fails to operate, do not attempt to put the furnace into

operation. Contact a qualified heating contractor to service the furnace.

: A fire or explosion may result causing property damage, personal injury or loss of

life if you do not follow these instructions exactly.

: Homeowners attempting maintenance other than that covered as homeowner/user

maintenance may cause conditions which could result in personal injury or property damage.

: Shut off the power to the furnace before removing blower compartment door to avoid

injury from moving parts.

: This furnace is not to be used for temporary heating of buildings or structures under

construction.

: Call a qualified heating contractor to report suspected deficiencies (Do not attempt to

1. The furnace area must be kept clear and free of combustible materials, gasoline and other
flammable vapors and liquids.

6

All installations and services must be performed by qualified service personnel.

2. The furnace must be kept free and clear of insulating material. The furnace area should be
examined when the furnace is installed or when insulation is added. Insulating materials may be
combustible.

3. For proper and safe operation the furnace needs air for combustion and ventilation. Do not
block or obstruct air openings on the furnace, air openings to the area in which the furnace is
installed, or the spacing around the furnace.

4. This furnace is equipped with a blocked vent shut off system. In the event that an obstruction
or restriction occurs in the vent pipe or termination, the furnace will shut off and the control will
flash an error code. This prevents the formation of hazardous gas products and prevents any
release of exhaust gas into the home. If the furnace fails to operate, contact a qualified service
agency.

5. Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the
furnace before shutting off the electrical supply.

6. Do not use this furnace if any part has been under water. A flood damaged furnace is
extremely dangerous. Attempts to use the furnace can result in fire or explosion. A qualified
service agency should be contacted to inspect the furnace and to replace all gas controls, control
system parts, electrical parts that have been wet or the furnace if deemed necessary.

7. Visually examine the furnace at the start of the heating season and monthly during the heating
season.

(a.) All flue gas carrying areas external to the furnace (i.e chimney, vent connector) are
clear and free of obstructions.

(b.) The vent connector is in place, slopes upward and is physically sound without holes
or excessive corrosion.

(c.) The return air duct connection is physically sound, is sealed to the furnace casing,
and terminates outside the space containing the furnace.

(d.) The physical support of the furnace is sound without sagging cracks, gaps, etc.,
around the base so as to provide a seal between the support and the base.

(e.) There are no obvious signs of deterioration of the furnace.

(f.) The pilot and burner flames are in good adjustment (by comparison with pictorial
sketches or drawings of the main burner flame and, if applicable, the pilot burner flame).

7

All installations and services must be performed by qualified service personnel.

A. ANNUAL INSPECTION

The homeowner must have this furnace professionally inspected at the beginning of each heating
season by a qualified heating contractor to ensure proper operation.

NOTICE: This furnace has been shipped from the factory with a permanently lubricated
circulating air blower motor. Any maintenance to this blower motor is to be performed only by a
qualified heating contractor.

B. FILTER MAINTENANCE PROCEDURE

1. The return air filter provided with this unit is a re-useable type filter. This filter should be
inspected monthly. When dirty, the filter must be cleaned or replaced, if necessary, to assure
proper furnace operation. Follow the cleaning, removal and replacement procedure below.

NOTICE: If the furnace is installed in a home or structure being remodeled, dust levels may be
much higher than normal. The filter must be inspected daily and cleaned as needed until dusty
conditions have been eliminated.

: This furnace is not to be used for temporary heating of buildings or structures under

construction.

2. The filter rack or drop chute will be located between the return air plenum and the return air
opening of the furnace (See Figure 3). Slide dirty filter out of the filter rack. Clean the filter
by vacuuming, rinsing with tap water, hosing or dipping in an ordinary detergent solution.
Replace the completely dry filter in the rack. The mesh side of the filter must be installed
towards the furnace after cleaning.

All installations and services must be performed by qualified service personnel.

C. VISUAL INSPECTION PROCEDURE

It is recommended that the homeowner/user conduct the following periodic visual inspection of
the furnace at the start of the heating season and monthly during the heating season.

: Call a qualified heating contractor to report suspected deficiencies (Do not attempt to

make repairs yourself!)

1. Turn off power to furnace.

2. Vent pipe, air intake pipe, and condensate system: Visually check the vent and intake pipe as
well as condensate lines both inside and outside the furnace to make sure that vent intake
joints and the condensate system are sealed. There should be no sign of water leakage at any
vent intake or condensate joints or anywhere inside the furnace. Make sure that horizontal
runs of vent pipe slope upward towards the outside. The inlet pipe should slope slightly
downward to prevent condensate build up. Any signs of damage, leakage, deterioration, or
possible blockage should be immediately reported to your dealer or the local gas company.

It is recommended that the condensate removal system be cleaned annually by a qualified service
agency to insure its proper and continued operation.

Outside vent and outside combustion air termination: the outside vent terminations should be
inspected to insure that they are clear and free of obstruction by ice, snow, debris, of vegetation.
Any obstruction of the terminal should be carefully removed without damaging the vent terminal.
If ice has formed on the outside terminals themselves, it should be removed.

3. If the furnace is equipped with a Thermo Products, LLC. condensate neutralizer kit, (See

Figure 4) it should be inspected at the start of every heating season. Remove the 2” PVC cap
from the neutralizer kit and replace dissolved filter material with #9 limestone. Keep instructions
for neutralizer kit in plastic pouch on the inside of the furnace blower door.

Figure 4

4. Return Air Duct Connection: Check to see if it is (1) physically sound; (2) sealed to the

furnace casing; and (3) terminates outside the space containing the furnace.

14

All installations and services must be performed by qualified service personnel.

5. Examine the entire furnace, including removing the vestibule door and inspect the control

compartment and the furnace for signs of damaged or unusually worn wiring, condensation,
sooting or other damage or deterioration.

6. Restore power to the furnace. Follow the operating instructions to light furnace.

7. Make sure the gas is burning properly (See Figure 5). Burner flames should not impinge or fire

against the side of the tube opening.

NOTICE: It is not unusual to have orangish flames visible in the tube for LP gas.

: Call a qualified heating contractor to report suspected deficiencies (do not attempt to

make repairs yourself!)
