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.
PRODUCING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA
54/ANS 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 The information on pages 4 through 6 will help you classify your space and provide adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.
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 per pa-sec-m openings gasketed or sealed b. weather stripping has been added on openable windows and doors
and
c. caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings. If your home meets all of the three criteria above, you must provide additional fresh air.
See Ventilation Air from Outdoors, page 6.
If your home does not meet all of the three criteria above, see
Determining Fresh-Air Flow for Heater Location, page 5.

Confined and Unconfined Space
The National Fuel Gas Code ANS 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 of the aggregate input rating of all appliances 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 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. This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if you have a Confined or Unconfined Space*
Use this worksheet to determine if you have a confined or unconfined space. Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space (length Length Example: Space size 20ft. (length) 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.
(volume of space)÷50 cu. ft.=(Maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51.200(maximum Btu/Hr the space can support)
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes.

*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.
4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
Btu/Hr (maximum the space can support) Btu/Hr (actual amount of Btu/Hr used)
Example : 51,200 Btu/Hr(maximum 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, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 5. B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6 . C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.
If the 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.

THERMOSTAT
CONTROL
OPERATION
The thermostatic control used on these models differs from standard thermostats. Standard thermostats simply turn on and off the burner.The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner.
This increases or decreases the burner flame height. At times the room may exceed the set temperature. If so the burner will shut off. The burner will cycle back on when room tem­perature drops below the se temperature. The control knob can be set to any heat level between HI and LO. Selecting the HI setting will cause the burner to remain fully on withou modulating down in most cases.

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot flame pattern. Figure 22 shows an incorrect pilot flame pattern. The incorrect pilot flame 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 Appliance on page
12 for non-thermostat model or page 11 for thermostat model) see Troubleshooting on pages 14 through 16
Figure 21 - Correct Pilot Flame Pattern
Figure 22 - Incorrect Pilot Flame Pattern
WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this page.
Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.

CLEANING AND MAINTENANCE
WARNING: Turn off heater
and let cool before servicing.
CLEANING ODS/PILOT AND BURNER
Use a vacuum cleaner,
pressurized air or small, soft
bristled brush to clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every 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 PSl. Y our local computer store, hardware store, or home center may carry compressed air in a can. You can use a vacuum cleaner in the blow position. If 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 pilot assembly.
1. Shut off the unit, including the pilot. Allow the unit to cool for
at least thirty minutes.
2. Inspect burner, pilot for dust
and dirt.
3. Blow air through the ports/slots
and holes in the burner. Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a 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.
BURNER FLAME PATTERN
Figure 23 shows a correct burner flame pattern. Figure 24 shows an incorrect burner flame pattern. If pilot flame pattern is incorrect, as shown in Figure 24. turn heater off (see To T urn Off
Gas To Appliance on page 12 for
non-thermostat model or page 1 1 for thermostat model) see Troubleshooting on pages 14 through 16
