SOURCEOFHEAT WHENINSTALLED,OPERATED AND MAINTAINEDASRECOMMENDEDINTHESE INSTALLATION
ANDOPERATINGINSTRUCTIONS. READ THESEINSTRCTIONSTHOROUGHLY BEFOREINSTALLING,SERVICING,OR
USING THIS APPLIANCE. IF YOU DO NOT UNDERSTAND ANY PART OF THESE INSTRUCTIONS, CONSULT LOCAL
AUTHORITIES,OTHERQUALIFIEDINSTALLERS,SERVICEAGENCIES,THEGASSUPPLIER,ORTHEMANUFACTURER.
VENTING
This heater must be connected to a properly installed and maintained venting system. This heater is equipped with a vent safety
shut-off device. Pilot outage will occur if the heater is not connected to a vent system. Pilot outage may occur due to restriction or
blockage in the vent or if connected to a masonry chimney having an area greater than the vent size shown on Page 2.
This appliance should be vented through a properly sized listed type B vent that has been constructed in accordance with the
National Building Code. If a horizontal section of vent is used, it must slope upwards a minimum of ¼ inch per foot of length.
This heater must not be connected to a vent system being used for wood or coal burning appliances. The use of more than one
appliance per vent system will most likely cause the vent safety shut-off device to shut off the heater due to the cooling of vent
temperatures through the draft diverter of the second appliance. In some situations, the vent safety shut-off may shut down the
heater if a too large, unlined, masonry chimney is used. Due to low vent temperatures associated with more efficient heaters it may
take too long to get the vent action going in a chimney before the shut-off device will shut down the heater. If this is the case, we
recommend lining the chimney with the proper size type B vent pipe or type B chimney liner.
WARNING: Do not bypass the vent safety shutoff switch. To do so could expose the consumer to
property damage, personal injury or possible death.
The switch, when activated, will extinguish the pilot flame. If the homeowner experiences this problem, the vent system must be
checked and corrected. NOTE: An existing vent that has worked for years may not be adequate for todays design because of
higher efficiency requirements resulting in lower stack temperatures. The following is a list of possible causes and corrective
actions.
POSSIBLECAUSES CORRECTIVE ACTION
1. Blockage in vent pipe 1.A) Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc.
1.B) Check that the vent cap is properly installed, not shoved too far down on the vent
pipe.
2. Burner is over firin 2.A) Check the manifold pressure.
2.B) Check the rate, NOTE: This appliance was orificed for elevations up to 2,000 feet.
When installed at higher elevations refer to orifice chart in main burner orifice
section of instructions for proper orifice size and re-orifice accordingly.
3. Improper vent system 3. Correct vent system.
A) Vent too short A) The vent should not terminate less than 5 feet above the drafthood connection. A
gas vent extending through an exterior wall shall not terminate adjacent to the
wall or below eaves or parapets. Also, the top of the vent must be at least 2 foot
above any obstacles within a 10 foot radius, including the roof. See Figure A.
B) Restriction in vent B) All type “B” vent shall extend in a generally vertical direction with offsets not
system caused by exceeding 45 degrees, except that a vent system having not more than one 60
offsets degree offset may be allowed. Any angle greater than 45 degrees from the vertical
is considered horizontal. The total horizontal run of a vent plus the horizontal vent
connector shall be not greater than 75 percent of the vertical height of the vent.
Any offsets used should be as far above the drafthood as possible to allow a
venting action to begin before any restriction is encountered.
C) Incorrect vent pipe C) Use listed “B” type vent pipe. Do not use transite or any other type of ceramic
pipe for venting. Do not use single wall pipe.
4. Loose connections on the 4. Check the connection on both the switch and the gas valve. Tighten if necessary.

COMBUSTIONAND VENTILATIONAIR
When installed, this gas appliance must be provided with fresh air for
combustion, ventilation, and dilution of hot flue gases. The minimum required
volume of the area where the appliance is installed should be 50 cubic feet per
1,000btu/hr.
If installed in an area of the home that is considered an unconfined space, the
natural infiltration of air around windows and doors will be adequate. If the
area is considered a confined space (less than 50 cubic feet per thousand btu),
fresh air can be supplied by providing two permanent openings into adjoining
rooms. Each opening shall have a minimum free area of one square inch per
1,000 btu per hour of the total input rating of all gas appliances in the confined
space, but not less than 100 square inches. One of the openings shall be within
12 inches of the ceiling and one within 12 inches of the floor. See Figure A.
If the home is of unusually tight construction (new and remodeled homes), free
air must be supplied through opening(s) to the outdoors. This can be
accomplished by providing 2 permanent openings, one commencing within 12
inches of the ceiling and one within 12 inches of the floor. These openings
shall communicate directly with the outdoors, or spaces that communicate
freely with the outdoors, such as a ventilated attic and crawl space through
galvanized or equivalent corrosion-resistant ducts. Exception: unobstructed
stud and joist spaces are acceptable ducts provided that not more than one fire
block is removed. Special provisions must be taken to insure that these stud
and joist spaces cannot be blocked with insulation or other objects. Each of
these openings using vertical ducts shall have a minimum free area of one
square inch per 4,000 btu/hr of total input rating of all gas appliances. See
FigureB and C. If horizontal ducts areused,the minimum free area shall beone
square inch per 2,000 btu/hr of total input rating of all gas appliances.
Fresh make-up air can also be provided through a duct to one permanent
openingcommencingwithin 12 inches of the ceiling. The minimumfreeareaof
this opening shall be one square inch per 3,000 btu/hr of the total input rating
of all gas appliances but not less than the sum of the areas of all vent connectors
in the space. See Figure D.
When calculating the amount of fresh air needed you must include make-up air
requirements for the operation of exhaust fans, kitchen ventilation systems,
clothes dryers, and fireplaces.
Additional information can be found in the latest edition of ANSI Z223.1
(NationalFuel Gas Code).

MAIN BURNER ORIFICE
This appliance was shipped from the factory with an orifice
sized to give the correct gas input using the gas for which the
heater was equipped. There may be local conditions, such as
variation in gas pressure or BTU content of the gas, which
may be cause for a change in the orifice. The gas company
supplying the fuel or the installing contractor should check
the gas input rate.
If the rate exceeds the “BTUH INPUT” on the rating plate by
5%, the orifice should be replaced with a smaller orifice by a
qualified technician to reduce the input to the rating plate
value.
The input rate may need to be adjusted for elevation. See the
following charts to determine the correct orifice size for your
Model Number and elevation. These orifice sizes are based
on a heating value of 1020 for Natural Gas and 2500 for L.P.
Gas.
CAUTION: Aselevationincreases, derating is necessary for
the safe and proper operation of this heater. Do not increase
the Btu input rate by increasing the orifice size or gas
pressure. Allowforelevation derating when sizing gas heating
equipment.

MAINTENANCE
CLEANING: To clean the front casing of your heater, it is
onlynecessary to use a soft cloth. Lightdustcan be removed
in this way. To obtain a polish or gloss, use a little light
machineoil on the cloth. Do not usemetalpolish or cleaning
solution. The burner ports should be kept free from lint and
dust.
CLEANINGOF COMBUSTIONCHAMBER
The combustion chamber of your console heater should
never need to be cleaned if proper burner adjustment and
gas pressures are maintained. However, if an unusual
circumstance should occur, the following procedure should
be followed in cleaning your combustion chamber.
1. Turn off gas supply to heater at manual valve in
supply line to heater.
2. Disconnect heater at ground joint union ahead of
main gas valve.
3. Remove main control and orifice assembly.
4. Remove burner.
5. Remove combustion chamber.
6. Using a scraper, scrape inside of a primary
combustion chamber. This should be area of
heaviest accumulation of carbon.
7. Remove plug bottom located in bottom rear of
second combustion chamber. Using a bottlebrush,
clean inside of this chamber. Shake residue out the
clean-out hole.
8. Clean the rear chamber by using bottlebrush
through the vent tube openings.
9. Replace combustion chamber, burner and control.
Checkallgaspipingforleaksbeforelighting heater.
Repair service should be performed by qualified persons.
The heater should be inspected before initial use. An annual
cleaning of control compartment and safety performance
check should be made by a qualified service person. More
frequent cleaning may be required when exposed to the
excessive lint conditions due to carpeting and bedding
material, etc. It is imperative that the control compartment,
burners, and circulating air passageways of the heater be
kept clean. Any safety screen, casing top, or guard removed
for servicing the heater must be replaced prior to operating
heater.
If the venting system is not maintained in proper operating
condition, the vent safety shutoff will not allow heater to
operate. Periodic examination of the entire venting system
as a routine part of the safety performance check is
recommended on an annual basis.
Itis advised that the pilot andmainburner flames be checked
at least twice during the heating season for any changes in
flame characteristics. See Figure 2 and Figure 3.
