My heater won't lite.

Over the summer months dust, dirt, and fifty-fifty spiders may have settled into an idle heater. This can clog the airplane pilot light orifice. A unproblematic cleaning could have this heater operating in less than 15 minutes. Follow the instructions in your Possessor's Manual.

My airplane pilot low-cal keeps going out.

The most common reason is that dust and dirt are starting to build upwards, but are non yet quite bad enough to prevent the heater from lighting all together. A simple cleaning could have this heater operating in less than 15 minutes. Run across the cleaning and maintenance information department beneath.

If this problem is happening during installation or when other gas appliances supplied past the same line are in operation, you lot may have low gas pressure level.  This could be acquired by either using too small of a bore supply line or low inlet pressure. Contact y'all gas supplier.

If you lot are trying to use a vent free gas appliance at a location higher than 4500 feet, the pilot will not stay lit equally the air is also thin and there is non enough oxygen for proper operation. At that place is no solution for this.

If yous accept hooked the heater up to the incorrect gas type, you may accept this problem. Bank check your gas supply.

If your heater operates for awhile and so shuts off, including the airplane pilot, you may be using the appliance in likewise minor of a space. Vent Free Appliances crave sufficient oxygen to operate.  This problem is most commonly found when too large of an appliance is used in likewise small of a space, although it tin occur if a house is very tightly insulated. Adding additional ventilation can exist every bit simple every bit opening a window. Check your Possessor's Manual for more details on ventilation.

For dual fuel wall heater units operating on natural gas, please bank check out our extra bulletin on this issue: Dual fuel units go on shutting downwardly on natural gas

Cleaning and maintenance of your heater

WARNING: Improper installation, aligning, alteration, service, or maintenance can cause injury or holding damage. Refer to the Owner'S MANUAL for right installation and operational procedures. For assistance or additional information, consult a qualified installer, service bureau, or local gas supplier.

Caution: You must keep control areas, burner, and circulating air passageways of appliance clean. Inspect these areas of appliance before each use. Have appliance inspected yearly past a qualified service person. Appliance may need more frequent cleaning due to excessive lint from rug, bedding material, pet hair, etc. Failure to perform this maintenance can lead to soot buildup effectually the appliance and throughout the area.

Nosotros recommend that yous clean the unit at least every two to 3 months or after 2000 hours of operation. More than frequent cleaning may be needed based on how and where yous use your heater. A xanthous tip on the pilot flame or lifting of the flame indicates grit and dirt in the pilot assembly. If you experience difficulty in keeping the pilot low-cal lit, follow the maintenance steps noted below. See your Owner's Manual for complete details. We besides recommend that you proceed the burner tube and airplane pilot assembly make clean and free of dust and dirt. To make clean these parts nosotros recommend using compressed air no greater than 30 PSI. You can also employ a vacuum cleaner in the blow position. If using compressed air in a tin, delight follow the directions on the can. Failure to follow these directions could damage the airplane pilot assembly.

1. Shut off the unit of measurement, including the pilot. Allow the unit of measurement to cool for at to the lowest degree xxx minutes.
2. Inspect burner, pilot, and primary air inlet holes on injector holder for grit and clay.
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the stop of the burner tube over again. Remove any big particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the chief air holes on the injector holder.
6. In instance any large clumps of dust have now been pushed into the burner repeat steps iii and 4.

Make clean the airplane pilot assembly. A yellow tip on the pilot flame or lifting of the flame indicates dust and clay in the pilot associates. There is a small-scale pilot air inlet hole nigh two inches from where the pilot flame comes out of the pilot assembly. With the unit off, lightly blow air through the air inlet hole. Y'all may blow through a drinking straw if compressed air is non available. Do Non insert anything into the pilot tube as this may damage the assembly.

Main BURNER
Periodically inspect all burner flame holes with the fireplace running. All slotted burner flame holes should exist open with xanthous flame nowadays. Some burner flame holes may become blocked by debris or rust, with no flame nowadays. If so, turn off fireplace and let cool. Either remove blockage or replace burner. Blocked burner flame holes will create soot. Only a qualified technician can replace parts.

CABINET
AIR PASSAGEWAYS

Use a vacuum cleaner or pressurized air to clean.

Exterior

Use a soft cloth dampened with a balmy soap and water mixture. Wipe the cabinet to remove grit.

LOGS
If the appliance has logs, check for night streaks, soot buildup, cracked, or cleaved pieces.

If you remove logs for cleaning, refer to OWNER'Due south Transmission to properly replace logs. About logs are designed to fit on retentiveness pins. Placement on these pins is very important.

Flames should be observed while in operation. If a log is improperly placed and the flame is impinging (coming in contact with) on the log it tin cause sooting and may produce carbon monoxide. If flames are impinging the logs, the unit should be turned off, allowed to absurd and so the appropriate log(due south) adjusted.

Supersede log(south) if broken or chipped (dime-sized or larger).

Caution

The following activities tin can cause SOOTING:

• Operating a ceiling fan
• Smoking cigarettes, cigars, pipes
• Muddied Burner or Pilot
• Dirty firebox/chimney
• Called-for candles or oil lamps
• Called-for incense
• Placing objects near or in the flame
• Flames touching logs

All installed gas products sold past World Marketing of America Inc. should only be installed and/or serviced by a qualified installer, service bureau, or gas supplier. The information published on this website is meant to further brainwash the end user. This information does not supersede the possessor's manual provided with the heater. The owner's manual must be read and all instructions followed to avoid potentially hazardous conditions.

My igniter won't spark. (Battery operated).

The battery may not exist installed, or is installed backwards.

The battery may be weak or expressionless. Try replacing it.

The igniter wire might simply exist loose and in need of tightening.

There could be a crack in the igniter wire. In this case you may see a spark from somewhere else on the wire. You may need to replace the wire if it is damaged.

My igniter won't spark. (Piezo Blazon).

If you do not hear a loud snap when y'all printing down on the igniter, the igniter needs replaced.

If you hear a loud snap, but there is no spark at the igniter, the igniter wire might but be loose and in demand of tightening.

If you hear a loud snap, but there is no spark at the igniter, there could be a crack in the igniter wire. In this instance you may come across a spark from somewhere else on the wire. You may need to supersede the wire if information technology is damaged.

There is no gas coming through the pilot?

If this is a new installation of a liquid propane (LP) apparatus it is likely that an external regulator was non installed. If the gas flows to the regulator under too much force per unit area, the internal regulator will close. This is not a defect.  Contact your qualified installer for additional data.

If as well small of a gas line is used, there may not be sufficient force per unit area to maintain the pilot light or the pilot may leave as soon equally the main burner is lit. The only solution is to install the correct sized piping.

If the water column force per unit area is too depression and piping of sufficient size has been used, contact your gas supplier to see if the gas pressure level can be increased.

When attempting to lite your appliance you must plough both the control knob to the pilot position and press the knob down at the aforementioned fourth dimension to start the flow of gas. The gas volition not period if the knob is non fully depressed. Once the pilot is lit, keep to concord down the valve for 30 seconds and release.  If the airplane pilot does not stay lit, you may take air left in the lines from installation. Repeat the lighting process until the airplane pilot remains lit. This may take several attempts afterwards initial installation.

Odors?

Operating your heater where impurities in the air exist may create odors. Cleaning supplies, pigment, paint remover, cigarette smoke, cements and glues, new carpet, candles, air freshners, textiles, etc., create fumes. These fumes may mix with combustion air and create odors. You lot volition want to ventilate the room of all odors and clean the unit.

Slight fume or aroma during initial operation?

Information technology'due south normal for some residue from the manufacturing process to be on the appliance. Operate the unit on high for four to six hours with your windows open to burn off the "NEW" odor and the smell should get away.

My gas stove/fireplace is smoking .

In most cases, this is a problem in log placement or employ. If a log is touching the flame or simply "licking" it once in awhile it will still leave soot. Wipe the appliance clean and burn down information technology without logs for an hour or then. Chances are it will be clean indicating that you have placed the logs incorrectly. If the flames are billowy around, it may be a draft from a doorway or a ceiling fan causing the problem. If there seems to be fume coming off of a hot painted surface, then it's probably only some oil left behind from the factory. This will stop.

If the soot is not in the heater, but on the walls, effectually windows etc., then this is a sign that something in the air (household chemicals, dust, candle wax, cigarette smoke, etc.) is being burned. This volition stop once the air in the room is clean and clear of contaminants. Other factors affecting the heater tin can be a lot of cooking odors in the air, loftier moisture from a big family with heavy shower use, any remodeling, etc.

Problems in use above 4500 ft.

Vent-free heaters will not work consistently above 4500 feet. At these elevations in that location is not plenty pure oxygen nowadays to produce the right pilot flame. The flame will burn high and erratically as information technology "hunts" for oxygen to burn. This erratic flame fails to rut the thermocouple completely resulting in a drop in the millivolts produced and the gas valve shuts off the gas supply to the heater. There is no solution to solve this complaint. If your home is higher up 4500 feet y'all may need to look into appliances that do non require an ODS.

What is the difference betwixt vented and ventless heating?

Vented heating requires ventilation to the outside, either through piping or a damper in an existing fireplace.
Both types of heating are rubber provided the specific unit has been certified and installed co-ordinate to the manufacturer'south instructions.

Are Ventless gas products rubber to utilize the habitation?

Yes, most states in the US allow for the sale and installation of vent-free "supplemental" gas heat appliances.
Vent less products are equipped with an ODS pilot assembly, precision-engineered burners for clean burn and a not-adjustable regulator to foreclose over-firing. The purpose of the ODS is to shut off the supply of gas to the heater/fireplace when the oxygen level drops beneath eighteen%.
All major building codes categorize vent-free as "supplemental heat". Local codes may vary. California does not currently permit the use of vent-free installation. For more information refer to: www.ventfree.org

What are the restrictions for Ventless NG?

Natural gas from the ground is odorless. The characteristic "gas" odor is added later on past the supplier called "mercaptan", containing sulfur, which volition give it the characteristic "rotten egg" odor.
NG units cannot exist connected to a individual (non-utility) gas well, also known equally "well-head" gas. These are typically constitute in rural areas where at that place is not an admission to utility owned gas lines. This gas is odorless, therefore unsafe because a leak cannot be detected quickly.

What type of regulator is required exterior for a LP appliance?

Regulators are sized to the appliance, not the container you are connecting to. There are three (three) central pieces of information:
BTU Load of the appliance
Operating pressure of the appliance (W.C. eleven"-14" of water column pressure)
The required inlet and outlet pipe size. ( Refer to Troubleshooting Section)
The "Integral Twin Phase System" is the virtually common for residential installations. If the propane tank is fifteen' or more from the appliance, a "Two-Phase Arrangement" is recommended because of the propane required for the appliance to run correctly and efficiently.

            Integral Twins Ii Phase System                                                        2 Stage Organisation

What is the deviation between a dedicated gas product vs. dual fuel?

Dedicated products are manufactured with parts engineered specifically for either natural gas or propane (LP) and cannot be converted from one gas to another.
Dual fuel products offer the choice of using natural gas or propane (LP)

What does the term"BTU" mean?

A "BTU" is a British Thermal Unit. BTU is the amount of energy it takes to raise one (1) pound of h2o ane-degree Fahrenheit.
• 1 BTU = the estrus generated past 1 lit matchstick.
• BTU limitations based on the cubic feet of air bachelor in an area.
• Manifold pressure level and orifice size determines the BTU output of the burners.

What is "Water Column Pressure" (West.C.)?

Low pressure is any pressure below 1 pound per foursquare inch (PSI). When dealing with pressures below one PSI, y'all volition encounter the term "inches" or "inches of water column". This refers to the amount of pressure it takes to raise a column of water 1 inch. There are 27.7 inches of water column (West.C.) pressure level in ane PSI of pressure.
Due west.C. is measured with a "manometer" (force per unit area gauge), which measures the pressure of gases and vapors.

• seven.0″ W.C. = approx. ¼ lb. PSI
• xiii.five" W.C = approx. ½ lb. PSI
Regulator W/Plunger
• For LP: Unit needs 11.0" – fourteen.0" West.C.
• For NP:
No-Step Regulator
• For LP: Unit needs 11.0" – 14.0" W.C.
• For NP:
Note: The maximum pressure in a residential dwelling is 2 psi. Kozy-World/Comfort Glow units are depression-pressure systems. For NG, an additional meter may be needed if abode is on a 2 psi system

What is an "Oxygen Depletion Sensor" (ODS)?

All Ventless or Vent-Costless appliances are equipped with an ODS pilot assembly. The purpose of the ODS is to shut off the supply of gas to the heater/fireplace when the oxygen level drops below 18%.
During operation, if the pilot flame goes out for any reason, the thermocouple or thermopile volition cool and shut the gas valve that supplies the supply to the burner, shutting down the heater. There must exist adequate air ventilation for units to function properly.
ODS system contains a precision orifice. This ODS has a "ruby" orifice and designed to disintegrate with any attempt at drilling it out to overstate the airplane pilot flame. Additionally, it is non interchangeable with a normal standing pilot. Trying to burn down gas at extremely low oxygen levels can cause deadly gases and high levels of Carbon Monoxide.

 Normal Operation Oxygen Level Dropping Safety Shutdown

Normal Performance - xx.ix% Oxygen - Pilot flame engulfs tip of the thermocouple, generating the millivoltage needed to hold the safe pilot valve open up.

Oxygen Level Dropping - xix% Oxygen - The flame begins to lift-off the precision pilot burner, causing the thermocouple to cool.

Safety Shutdown - 18% Oxygen - The unstable pilot flame moves away from the thermocouple causing the thermocouple to finish generating the electricity needed to hold the spring loaded safety valve open causing the flow of gas to finish.

What is "Carbon Monoxide"?

Carbon Monoxide (CO) is measured in parts-per million(ppm) An average cigarette emits threescore-ppm depict or drag. Vent-Gratuitous products emit only 8ppm of CO over a three (3) hour period. Occupational Wellness and Safety Association (OSHA) considers air quality at 200 ppm of CO to exist unsafe. Vent-Costless appliances are 99.9% efficient and are safer to operate than a gas range.
Carbon Monoxide Level of Toxicity:
• 200 ppm > Slight headache within two-iii hours.
• 400 ppm > Frontal headache with 1-2 hours, condign widespread in iii hours
• 8400 ppm > Dizziness, nausea, convulsions within 45 minutes, insensible in ii hours.
Vent-free products are AGA approved, therefore certified to adapt to National emissions Standards. A Carbon Monoxide detector is not required for product installation.

What is "water vapor" and it's relation to vent-costless heating?

Water vapor is a by-product of gas combustion. An unvented room heater produces approximately 1 (1) oz. (30ml) of water every 1,000 BTU'southward (.3KW's) of gas input per hour. Unvented room heaters are recommended every bit supplemental heat rather than principal estrus source. In most supplemental heat application, the water vapor does not create a trouble. In most applications, the water vapor enhances the low humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not go a problem:
• Heater sized properly for the awarding, including ample combustion air and apportionment air.
• Feel high humidity, a dehumidifier may be used to help lower the water vapor content of the air
• 8400 ppm >Do not employ an unvented room heater as the "primary heat source"
Case: Vapor (sweating) on windows or walls – unit is too large for the area.

What is the departure between Blue Flame and Infrared?

Blue Flame Infrared (Plaque)

Blue Flame - Heats like a cardinal heating system, heating the air outset and then circulating warmth throughout the room, the hot air rises.  May take longer to heat the room as it works to "convect" the entire area.  Typically works improve in insulated areas.

Infrared (Plaque) -Heats like the sun, radiating warmth, directly heating the objects in the room start, heating outward.  Feels more than similar standing in front of a burn down.  Typically works ameliorate in un-insulated areas as they will heat objects before the air.

Where tin can I install a Ventless or Vent Free heating product?

Never install the heater:
• Over ten,000 Btu/Hour in a bathroom
• Over half dozen,000Btu/60 minutes in bathroom (Check local codes.)
• In a recreational vehicle
• Where curtains, furniture, habiliment, or other flammable objects are less than 36″ from the front, top, or sides of the heater
• In loftier traffic areas
• In windy or drafty areas
Important: Delight check your local and state codes for vent-free appliance installation.
Delight review the owner/operator Installation manual for a specific model.
