FRESH AIR FOR COMBUSTION AND
VENTILATION
WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas
Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for
Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications:
1.
Unusually Tight Construction
2.
Unconfined Space
3.
Confined Space
This heater must not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.
The information on pages 3 through 5 will help you classify your space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you must provide additional fresh air. See Ventilation Air
from Outdoors, page 5.
Unusually tight construction is defined as construction where: a. Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6 x 10 -11 kg per pa-sec-m 2 ) or less with openings gasketed or sealed and b. Whether stripping has been added on openable windows and doors, and c. Caulking or sealants are applied to areas such as joints around windows and door frames, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
If you home does not meet all of the three criteria above, see Determing the Type of Heater Location
Space, page 4.
Confined Space and Unconfined Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m 3 per kW) of the aggregate input rating of all appliances
Installation instructions and Owner’s Manual
installed in that space, and an unconfined space as a space whose volume is not less than 50 cubic feet per
1,000 Btu per hour (4.8 m 3 per kW) of the aggregate input rating of all appliances installed in that space.
Rooms communicating directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined space.
*Adjoining rooms are communication only if there are doorless passageways or ventilation grills between them.
DETERMINING THE TYPE OF HEATER
LOCATION SPACE:
Use this method to determine if you have a confined or unconfined space.
Note: the space includes the room in which you install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.
1. Find the volume of the space by multiplying room length x width x height.
Example: Space size 18ft (length) x 18ft. (width) x 8ft.
(height) = 2592
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum Btu/hr the space can support.
Example: 2592 cu.ft. (volume of space) / 50 cu.ft. = 51.8
or 51,800 (maximum Btu/hr the space can support)
WARNING: If the area in which the heater may be operated is smaller than defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by the methods described in the National Fuel Gas
Code, NFPA 54/ ANSI Z223.1, Section 5.3 or applicable local codes.
3. Add the Btu/hr of all the fuel-burning appliances in the space such as, Vent–free heater, Gas water heater,
Gas furnace, Vented gas heater, Gas fireplace logs, and Other gas appliances*
*Do not include direct-vent gas appliances. Directvent draws combustion air from the outdoors and vents to the outdoors.
Example:
Gas water heater 40,000 Btu/hr
Vent Free Heater + 20,000 Btu/hr
Total =60,000 Btu/hr
4. Compare the maximum Btu/hr the space can support with the actual amount of Btu/hr used.
Example: 51,800 Btu/hr (maximum Btu/hr the space can support)
60,000 Btu/hr (Actual amount of Btu/hr used)
The space in the above example is a confined space because the actual Btu/hr used is more than the maximum Btu/hr the space can support.
You must provide additional fresh air. Your options are as follows:
A. Rework worksheet, and the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between the rooms. See Ventilation Air
From Inside Building (Fig. 2).
B. Vent room directly to the outdoors. See Ventilation Air
From Outdoors (Fig. 3).
C. Install a lower Btu/hr heater if lower Btu/hr size makes room unconfined.
If actual Btu/hr used is less than the maximum Btu/ hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
VENTILATION AIR
Ventilation from Inside Building
This fresh air would come from an adjoining unconfined space. When ventilation to an adjoining unconfined space, you must provide two permanent openings: one within 12” of the ceiling and one within 12” of the floor on the wall connecting the two spaces (see options 1 & 2 of fig. 2). You can also remove door into adjoining room
(see option3, fig 2). Follow the National Fuel Gas Code
NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Ventilation from Outdoors
If necessary provide extra fresh air by using ventilation grills or ducts. Connect these items directly to the outdoors or spaces open to the outdoors. These include attics* and crawl spaces. Follow the National
Fuel Gas Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.
*IMPORTANT: Do not provide openings for inlet or outlet into attic. If attic has a thermostat-controlled power vent, heated air entering the attic will activate the power vent.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Fresh
Air for Combustion and Ventilation, pages 3 through
5.

THERMOSTAT CONTROL OPERATION
FOR IR20NGT / IR30NGT: The thermostatic control used simply turns on and off the burner.
FOR BF20NGT / BF30NGT: The thermostatic control used modulates the flame size as the temperature gets closer to set point, then it turns off the burner upon reaching temperature.
The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any heat level between 1 and 5. Selecting the
HI setting will cause the burner to remain on.
Note: The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with room temperature
(depending on housing construction, insulation location, room size, open air temperature, etc.).
Frequent use of your heater will let you determine your own comfort levels.
The LED temperature indicator measures approximate room temperature around the heater.
Note: The LED temperature indicator DOES NOT operate with or control the thermostat setting of the heater.
TO TURN OFF GAS TO APPLIANCE
SHUTTING OFF HEATER

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 21 show a correct pilot flame pattern. Figure 22 shows an incorrect pilot flame pattern. The incorrect pilot flame pattern is not touching thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 22:
• Turn heater off (see To Turn OFF Gas to Appli-
ance, page 11 for non-thermostat models or page 12 for thermostat models).
• See Troubleshooting, pages 14 and 15.
Figure 21
BURNER FLAME PATTERN
Figure 23 show a correct burner flame pattern. Figure 24 shows an incorrect burner flame pattern. If burner flame pattern is incorrect, as shown in Figure 24:
• Turn heater off (see To Turn OFF Gas to
Appliance, page 11 for non-thermostat models or page 12 for thermostat models).
• See Troubleshooting, pages 14 and 15.

CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before servicing.
CAUTION: You must keep control areas, burner and circulation air passageways of heater clean.
Inspect these areas of heater before use. Have the heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excess lent from carpeting, bedding material, pet hair, etc.
Make sure grille guard is in place before running heater. If screen or grille guard is removed for servicing it must be replaced prior to operating the heater.
WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
CLEANING ODS/PILOT AND BURNER
• Use as vacuum cleaner, pressurized air or small soft bristled brush to clean.
CLEANING BURNER PILOT AIR HOLE INLET
We recommend that you clean the unit ever 2,500 hours of operation or every three months. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 psig.
This can be done by using a vacuum cleaner in the blow position, using compressed air in a can, please follow the directions on the can. If you don’t follow directions on the can you could damage the burner or pilot assembly. In addition, the directions that follow should also be followed.
1.
Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2.
Inspect burner and pilot for dust and dirt.
3.
Blow air through the port/slots and holes in the burner.
A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. To clean the pilot assembly find the small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see figure
25). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.
Figure 25
CLEANING HEATER CABINET

Always specify model and serial numbers when communication with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard written warranty. We make no other warranty, expressed or implied.
Enerco Group, Inc. warrants this product to be free from defects in materials and components for two (2) years from the date of first purchase, provided that the product has been properly installed, operated and maintained in accordance with all applicable instructions. To make a claim under this warranty the Bill of
Sale or cancelled check must be presented.
The warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore the heater to proper operating condition and an allowance for labor when provided by an Enerco Group, Inc. Authorized Service Center. Warranty part(s) MUST be obtained through authorized dealers of this product and/or Enerco Group, Inc. who will provide original factory replacement parts.
Failure to use original factory parts voids this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and instructions furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear of parts that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost, labor, transportation and any and all such costs related to repairing a defective heater will be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE
OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED
WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES OF MER-
CHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, TO TWO (2) YEARS OF ALL COMPO-
NENTS FROM THE FIRST DATE OF PURCHASE; AND ENERCO GROUP, INC.’S LIABILITY IS HEREBY
LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND ENERCO GROUP, INC. SHALL NOT BE
LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CON-
SEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation on incidental or consequential damages, so the above limitation on implied warranties, or limitation on damages, may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights that very from state to state. Always specify model and serial number when communication with the factory.
