AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a confined spaceorunusuallytightconstructionunlessprovisionsareprovided for adequate combustion and ventilationair.Readthefollowing instructionstoinsureproperfresh air for this and other fuel-burning appliances in your home.

Todayʼs 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 are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, 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 7 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 x 10-11 kg per pa-sec-m2) or less with openings 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 these three criteria, you must provide additional fresh air. See Ventilation Air From Outdoors, page 7.

If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow For Heater Location.

Confined and Unconfined Space

TheNationalFuelGasCode,ANSIZ223.1/NFPA54 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliancesinstalledinthatspaceandanunconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu/Hr (4.8 m3 per kw) of the aggregate input rating of all appliances installed in thatspace.Roomscommunicatingdirectlywiththe spaceinwhichtheappliancesareinstalled*,through openings not furnished with doors, are considered a part of the unconfined space.

* Adjoining rooms are communicating only if therearedoorless passagewaysorventilation grills between them.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this work sheet 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.

If the actual Btu/Hr (kw) used is less than the maximum Btu/Hr (kw) the space can support, the space

1.Determine the volume of the space (length x is an unconfined space. You will need no additional

width x height).

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.Multiply the space volume by 20 to determine the maximum Btu/Hr (kw) the space can support.

__________ (volume of space) x 20 = (Maximum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)

3.Add the Btu/Hr (kw) of all fuel burning appliances in the space.

Vent-free heater	________ Btu/Hr (kw)
Gas water heater*	________ Btu/Hr (kw)
Gas furnace	________ Btu/Hr (kw)
Vented gas heater	________ Btu/Hr (kw)
Gas fireplace logs	________ Btu/Hr (kw)

Other gas appliances* +________ Btu/Hr (kw)

Total

=________ Btu/Hr (kw)

* Do not include direct-vent gas appliances. Di- rect-vent draws combustion air from the outdoors and vents to the outdoors.

Example:	40,000 (11.7)
Gas water heater		Btu/Hr (kw)
Vent-free heater	+ 22,000 (6.4)	Btu/Hr (kw)
Total	= 62,000 (18.2)	Btu/Hr (kw)

4.Compare the maximum Btu/Hr (kw) the space can support with the actual amount of Btu/Hr (kw) used.

___________Btu/Hr(kw) (maximumthespacecansupport)

___________Btu/Hr (kw) (actual amount of Btu/Hr used)

Example: 51,200 Btu/Hr (15 kw) (maximum the space can support)

62,000 Btu/Hr (18.2 kw) (actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr (kw) used is more than the maximum Btu/Hr (kw) the space can support. You must provide additional fresh air.Your options are as follows:

A.Reworkworksheet,addingthespaceofanadjoiningroom.Iftheextraspaceprovidesanunconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building.

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

WARNING:Iftheareainwhich 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 byoneofthemethodsdescribed in the National Fuel Gas Code, ANSIZ223.1/NFPA54Section5.3 or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" (30.5 cm) of the ceiling and one within 12" (30.5 cm) of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoiningroom(seeoption3,Figure2).Followthe

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 3/8" NPT (National

PipeThread)inletconnectionto the pressure regulator.

WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.

WARNING: For natural gas, neverconnectheatertoprivate (non-utility) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: For natural gas, check gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5 inches (2.6 kPa) of water. If gas line pressure is higher, heater regulator damage could occur.

CAUTION: For propane/LP gas, never connect heater directly to the propane/LP supply.

This heater requires an external regulator (not supplied). Install theexternalregulatorbetweenthe heater and propane/LP supply.

For propane/LP gas, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incominggaspressuretobetween11and14inches (2.7 and 3.5 kPa) of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install the external regulator with the vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet.

	CAUTION: Use only new,
	black iron or steel pipe. Inter-
	nally-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
	volume will occur.
	Typical Inlet Pipe Diameter
	All models - 1/2" or greater
	Installation must include equipment 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 11).
	IMPORTANT:Install an equipment shutoff valve
	in an accessible location. The equipment shutoff
	valve is for turning on or shutting off the gas to
	the appliance.

INSPECTING HEATER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 20 shows a correct pilot flame pattern. Figure 21 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.

If pilot flame pattern is incorrect, as shown in Figure 21

•turn heater off (see To Turn Off Gas to Appliance, page 14)

•see Troubleshooting, page 17

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.
