Air For Combustion and Ventilation

WARNING: This heater shall notbeinstalledinaroomorspace unlesstherequiredvolumeofindoor combustion air is provided by the method described in the

National Fuel Gas Code, ANSI Z223.1/NFPA54,theInternational Fuel Gas Code,or applicable localcodes.Readthefollowinginstructionstoinsureproperfresh airforthisandotherfuel-burning appliances in your home.

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-burningappliances need fresh air for proper combustion and ventilation.

Exhaust fans, heaters, 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-burningappliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code. ANSI Z223.1/NFPA 54, 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 (6x10-11 kg perpa-sec-m2)or less with openings gasketed or sealedand

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-ceilingjoints, 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,youmustprovideadditionalfreshair.

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 Space and Unconfined Space

The National Fuel Gas Code ANSI Z223.1/ NFPA 54defines 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 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 m3 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 communicating only if there are doorless passageways or ventilation grills between them.

DETERMINING FRESH-AIRFLOW 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.

1.Determine the volume of the space (length x width x height).

Length x Width x Height =__________cu. ft. (volume of space)

Example: Space size 20 ft. (6.1m) (length) x 16 ft. (4.88m) (width) x 8 ft. (2.44 m) (ceiling height) = 2,560 cu. ft. (72.49 m2)(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 the space can support.

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

Example: 2,560 cu. ft. (72.49 m2) (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)

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

Vent-freeheater

__________ Btu/Hr

Gas water heater*

__________ Btu/Hr

Gas furnace

__________ Btu/Hr

Vented gas heater

__________ Btu/Hr

Gas heater logs

__________ Btu/Hr

Other gas appliances* +__________ Btu/Hr Total =__________ Btu/Hr

* Do not include direct-ventgas appliances.Direct-ventdraws combustion air from the outdoors and vents to the outdoors.

Example:

40,000

 

Gas water heater

Vent-freeheater

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.

_ _______ Btu/Hr (maximum can support)

_ _______ Btu/Hr (actual amount 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 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.

B.Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 7.

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.

WARNING:Iftheareainwhich theheatermaybeoperateddoes notmeettherequiredvolumefor indoorcombustionair,combustion and ventilation air shall be provided by one of the methods described in theNational Fuel GasCode,ANSIZ223.1/NFPA54, theInternational Fuel Gas Code, 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, page 7). You can also remove door into adjoining room (see option 3, Figure 2, page 7). Follow the National Fuel Gas Code, ANSI Z223.1/ NFPA 54, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

WARNING: Use pipe joint sealantthatisresistanttoliquid petroleum (LP) gas.

Install sediment trap in supply line as shown in Figure 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.

IMPORTANT: Hold the pressure regulator with wrench when connecting it to gas piping

and/or fittings. Do not over tighten pipe connection to regulator. The regulator body could be damaged.

CHECKING GAS CONNECTIONS

WARNING:Testallgaspiping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.

WARNING: Never use an open flame to check for a leak. Applyanoncorrosiveleakdetection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

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. 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 comfort level between 1 and 5. All plaques will turn off and 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, installation location, room size, open air temperatures, 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 9).

2.Follow steps 1 through 5 under Lighting

Instructions, page 14.

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. Now follow step 9 under Lighting Instructions, page 14.

5.Replace front panel.

Blower

Operation

WARNING: Blower accessory must be grounded. Blower comes with athree-prong,grounding plug as shown in Figure 24. The plug is your protection against electrical shock. Plug it into a standard,three-hole,grounded, outlet. If cordneedsreplacing,useonlyacordwithathree-prong,ground-ing plug.

CAUTION: Label all wires prior to disconnection when servicingcontrols.Wiringerrors cancauseimproperanddangerous operation.

CAUTION:Donotplugpower cord into electrical outlet until installation is complete.

Extension Cord

Use extension cord if needed. The cord must have a three-prong,grounding plug and athree-holereceptacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed. An undersized cord will cause a drop in line voltage. This will result in loss of power and overheating. Use a No. 16 AWG cord for lengths less than 50 feet.

CAUTION: Verify proper operation after servicing.

Operating Blower

The blower is connected to a thermostat. When unit heats up, the blower will operate. Afew minutes after unit cycles off or is turned off, blower will shut off. Blower will cycle on and off in this manner. Note: If you have a heater with a thermostat, the heater and blower will not turn off and on at exactly the same time. Blower cycle times will vary with heat setting selected.
