AIR FOR  
COMBUSTION  
AND  
WARNING  
WARNING ICON  
G
001  
This heater shall not be installed in a confined space 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.  
VENTILATION  
Today’s homes are built more energy efficient than ever. New materials, increased  
insulation, and new construction methods help reduce heat loss in homes. Home  
owners weather strip and caulk around windows and doors to keep the cold air out  
and the warm air in. During heating months, home owners want their homes as  
airtight as possible.  
While it is good to make your home energy efficient, your home needs to breathe.  
Fresh air must enter your home. All fuel-burning appliances need fresh air for  
proper combustion and ventilation.  
Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from  
the house to operate. You must provide adequate fresh air for these appliances.  
This will insure proper venting of vented fuel-burning appliances.  
PROVIDING ADEQUATE VENTILATION  
The following is 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.  
The information on pages 5 through 8 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 continu-  
ous water vapor retarder with a rating of one perm or less with open-  
ings gasketed or sealed and  
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 addi-  
tional fresh air. See Ventilation Air From Outdoors, page 8.  
If your home does not meet all of the three criteria above, proceed to page 6.  
Unconfined Space  
The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines uncon-  
fined space as having a minimum air volume of 50 cubic feet (127 cubic cm) for  
each 1000 Btu/Hr input rating of all appliances in the space (cubic feet equals  
length x width x height of space). Include adjoining rooms only if there are  
doorless passageways or ventilation grills between the rooms.  
Confined Space  
The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines confined  
space as having an air volume of less than 50 cubic feet (127 cubic cm) for each  
1000 Btu/Hr input rating of all appliances in the space (cubic feet equals length  
x width x height of space). Include adjoining rooms only if there are doorless  
passageways or ventilation grills between the rooms.

DETERMINING AIR FLOW FOR HEATER LOCATION  
AIR FOR  
COMBUSTION  
AND  
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.  
VENTILATION  
1. Determine the volume of the space (length x width x height).  
Continued  
Length x Width x Height =  
___________________  
cu. ft. (volume of space)  
Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =  
2560 cu. ft. (volume of space)  
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)  
3. Add the Btu/Hr of all fuel burning appliances in the space.

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)  
58,000 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 7.  
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.  
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.

CONNECTING  
TO GAS  
NOTICE  
A qualified service person must connect heater to gas supply.  
Follow all local codes.  
SUPPLY  
WARNING  
Never connect heater to private (non-utility) gas well. This gas is  
commonly known as wellhead gas.  
IMPORTANT: Check gas line pressure before connecting heater to gas line. Gas line  
pressure must be no greater than 14 inches of water. If gas line pressure is higher,  
heater regulator damage could occur.  
CAUTION  
Use only new, black iron or steel pipe. Internally-tinned copper  
tubing may be used in certain areas. Check your local codes. Use  
pipe of large enough diameter to allow proper gas volume to heater.  
If pipe is too small, undue loss of pressure will occur.

VN2000BTB/CFN2000BTB  
VN2800BTB/CFN2800BTB  
3/8" or greater  
1/2" or greater  
Installation must include a manual shutoff valve, union, and plugged 1/8" NPT tap.  
Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream  
from heater (see Figure 13, page 15).  
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant  
from going into pipe. Excess sealant in pipe could result in clogged heater valves.  
CAUTION  
Use pipe joint sealant that is resistant to natural gas.  
Install sediment trap in supply line as shown in Figure 13, page 15. Locate sediment  
trap where it is within reach for cleaning. Locate sediment trap where trapped  
matter is not likely to freeze. A sediment trap traps moisture and contaminants. This  
keeps them from going into heater controls. If sediment trap is not installed or is  
installed wrong, heater may not run properly.

OPERATING  
HEATER  
FOR YOUR SAFETY READ BEFORE LIGHTING  
WARNING  
If you do not follow these instructions exactly, a fire or  
explosion may result causing property damage, personal  
injury or loss of life.  
A. This appliance has a pilot which must be lighted by hand. When lighting  
the pilot, follow these instructions exactly.  
B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure  
to smell next to the floor because some gas is heavier than air and will  
settle on the floor.  
WHAT TO DO IF YOU SMELL GAS  
• Do not try to light any appliance.  
• Do not touch any electric switch; do not use any phone in your building.  
• Immediately call your gas supplier from a neighbor’s phone. Follow the  
gas supplier’s instructions.  
• If you cannot reach your gas supplier, call the fire department.  
C. Use only your hand to push in or turn the gas control knob. Never use  
tools. If the knob will not push in or turn by hand, don’t try to repair it,  
call a qualified service technician or gas supplier. Force or attempted  
repair may result in a fire or explosion.  
D. Do not use this appliance if any part has been under water. Immediately  
call a qualified service technician to inspect the appliance and to replace  
any part of the control system and any gas control which has been under  
water.  
LIGHTING INSTRUCTIONS  
1. STOP! Read the safety information above.  
2. Make sure manual shutoff valve is fully open.  
3. Turn control knob clockwise  
to the OFF position.

Continued  
C-clockwise  
5. Turn control knob counterclockwise  
to the PILOT position. Press  
in control knob for five (5) seconds (see Figure 16).  
Note: You may be running this heater for the first time after hooking up  
to gas supply. If so, the control knob may need to be pressed in for 30  
seconds. This will allow air to bleed from the gas system.  
• If control knob does not pop up when released, contact a qualified  
service person or gas supplier for repairs.  
6. With control knob pressed in, push down and release ignitor button. This  
will light pilot. The pilot is attached to the front of burner. The pilot can be  
seen through the glass panel. If needed, keep pressing ignitor button until  
pilot lights.  
Note: If pilot does not stay lit, refer to Troubleshooting, pages 22 through  
25. Also contact a qualified service person or gas supplier for repairs.  
Until repairs are made, light pilot with match. To light pilot with match,  
see Manual Lighting Procedure, page 19.

seconds, release control knob.  
• If control knob does not pop up when released, contact a qualified  
service person or gas supplier for repairs.  
Note: If pilot goes out, repeat steps 3 through 7. This heater has a safety  
interlock system. Wait one (1) minute before lighting pilot again.  
C-clockwise  
8. Turn control knob counterclockwise

Shutting Off Burner Only (pilot stays lit)  
1. Turn control knob clockwise

THERMOSTAT CONTROL OPERATION  
The thermostatic control used on these models differs from standard thermo-  
stats. 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 set 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 without modulating down in most cases.  
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, installation location, room size, open air tempera-  
tures, etc.). Frequent use of your heater will let you determine your own  
comfort levels.  
MANUAL LIGHTING PROCEDURE  
1. Remove front panel (see Figure 7, page 11).  
2. Follow steps 1 through 5 under Lighting Instructions, pages 17 and 18.  
3. With control knob pressed in, strike match. Hold match to pilot until pilot  
lights.  
4. Keep control knob pressed in for 30 seconds after lighting pilot. After 30  
seconds, release control knob.  
5. Replace front panel.

INSPECTING  
BURNER  
PILOT FLAME PATTERN  
Figure 18 shows a correct pilot flame pattern. Figure 19 shows an incorrect pilot  
flame pattern. The incorrect pilot flame is not touching the thermocouple. This will  
cause the thermocouple to cool. When the thermocouple cools, the heater will shut  
down.
