4. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought the heater.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (0.3 Kw) of gas input per hour. An unvented room heater is intended as a supplemental heater rather than a primary heat source. In most supplemental heat applications, the water vapor does not create a problem. In most applications, the water vapor enhances the low humidity atmosphere experienced during cold weather. The following steps will help ensure that water vapor does not become a problem:

1. Be sure the heater is the proper size for the application, including adequate combustion air and

circulation air.

2. If there is high humidity, a dehumidier may be used to help lower the water vapor content

of the air.

3. Do not use an unvented room heater as the primary heat source.

PREPARING FOR INSTALLATION

AIR FOR COMBUSTION AND VENTILATION

CAUTION: This heater shall not be installed in a room or space unless the required volume

of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANS Z223.1/NFPA54, the International Fuel Gas Code, or applicable local codes.

PRODUCING ADEQUATE VENTILATION

All spaces in homes fall into one of the three following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space The information on pages 7 through 9 will help you classify your space and provide adequate ventilation.

Conned and Unconned Space

A conned space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space and an unconning space as a space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconned space. This heater shall not be installed in a conned space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. * Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them.

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 dened as construction where: a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6x10-11kg per pa-sec-m2) or less with openings gasketed or sealed

and

b) weather stripping has been added on windows that can be opened and on doors and c) caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and oors, 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 9). If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

PREPARING FOR INSTALLATION

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Conned or Unconned Space

Use this worksheet to determine if you have a conned or unconned 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 × Width × Height = cu. ft. (volume of space) Example: Space size 20 ft. (length) × 16 ft.(width) × 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 cu. ft. 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. Vent-free heater _________ BTU/hr Gas water heater* ________BTU/hr Gas furnace _____________BTU/hr Vented gas heater ________BTU/hr Example: Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr Total = ____BTU/hr Total = 56,000 BTU/hr

*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) 56,000 BTU/hr (actual amount of BTU/hr used) The space in the above example is a conned 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 unconned space, remove door to adjoining room or add ventilation grills between rooms. See “Ventilation Air From Inside Building,” page 9. b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9. c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconned. If the actual BTU/hr used is less than the maximum BTU/hr the space can support, the space is an unconned space. You will need no additional fresh air ventilation.

PREPARING FOR INSTALLATION

Ventilation Air From Inside Building

This fresh air would come from adjoining unconned space. When ventilating to an adjoining unconned space, you must provide two permanent openings: one within 12 in. of the wall connecting the two spaces (see options 1 and 2, Fig. 1). You can also remove door into adjoining room (see option 3, Fig. 1). Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of

ventilation grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or duct. You must provide two permanent openings: one within 12 in. of the ceiling and one within 12 in. of the oor. Connect these items directly to the outdoors

or spaces open to the outdoors. These

spaces include attics and crawl spaces. Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation

grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a

thermostat-controlled power vent. Heated air entering the attic will activate the power vent. Rework worksheet, adding the space of the adjoining unconned space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

1. Attaching to wall stud: This method provides the strongest hold. Insert wood screws (ST.8*45-16) through mounting bracket and into wall studs.

2. Attaching to expansion bracket: This method allows you to attach mounting bracket to hollow walls (wall areas between studs) or to solid walls (concrete or masonry).

Decide which method better suits your needs. Either method will provide a secure hold for the mounting bracket.

Marking Screw Locations

1. Tape mounting bracket to wall where heater will be located. Make sure mounting bracket

is level.

2. Mark screw locations on wall (See Fig. 16). Note: Mark only last hole on each end of mounting bracket. Insert (2) wood screws (ST.8*45-16) total through these holes only.

3. Remove tape and mounting bracket from wall.

2. Place mounting bracket onto wall. Line up last hole on each end of bracket with holes drilled in wall.

3. Insert wood screws (ST.8*45-16) through bracket and into wall studs.

4. Tighten wood screws (ST.8*45-16) until mounting bracket is rmly fastened to wall studs.

5. Check that the bracket is secure before mounting heater!

INSTALLATION

Attaching to Expansion Bracket Method

For attaching mounting bracket to hollow walls (wall areas between studs) or solid walls (concrete or masonry):

1. Drill holes at marked locations using 5/16-inch drill bit. For solid walls (concrete or masonry), drill at least

1 inch deep.

2. Fold wall expansion bracket as shown in (See Fig. 17).

3. Insert wall expansion bracket (wings rst) into hole. Tap expansion bracket ush to wall.

4. For thin walls (1/2 inch or less), insert expansion bracket tool into expansion bracket. Push expansion bracket tool to “pop” open expansion bracket wings (See Fig. 18).

IMPORTANT: Do not hammer expansion bracket tool! For thick walls (over 1/2 inch thick) or solid walls, do not pop open wings.

5. Place mounting bracket onto wall. Line up last hole on each end of bracket with expansion bracket.

7. Tighten expansion bracket screws (ST4.8*15-16) until mounting bracket is rmly fastened to wall.

8. Check that the bracket is secure before mounting heater!

Attaching Wall Hanging Spacers to Heater

WARNING: Failure to properly install the wall hanging

spacers may result in property damage, personal injury

or even death.

1. Locate spacer mounting holes on the lower right/left sections of the heater back panel.

2. Secure (2) wall hanging spacers to heater back panel using (2) wall hanging spacer screws (M4*25) (See Fig. 19a).

2. Place heater onto mounting bracket. Slide horizontal slots onto stand-out tabs on mounting bracket. Be sure spacers rest evenly against wall (See Fig. 19b).

INSTALLATION

CONNECTING TO GAS SUPPLY

WARNING: A qualied service technician must connect heater to gas supply. Follow all local

codes.

IMPORTANT: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to

the pressure regulator. Never connect the heater to private (non-utility) gas wells, commonly known as wellhead gas.

WARNING: Do not overtighten gas connections.

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 1/2-in. diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

CAUTION: Two gas line installations at the same time are prohibited. The access plate to the

switching means shall not be opened while the heater is in operation.

CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure

must be a minimum 6'' WC for NG & 11" WC for LP with a max pressure of 14'' WC for NG & 14"

WC for LP. If gas line pressure is higher, regulator damage could occur.

CAUTION: Never connect heater directly to an LP supply. This heater requires an external

regulator (not supplied). Install the external regulator between the heater and gas supply.

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas

piping and/or ttings.

CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).

Typical Inlet Pipe Diameters

Use 3/8-inch black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8-inch NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Fig. 20).

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.

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.

INSTALLATION

Install sediment trap in supply line as shown (See Fig. 20). Place sediment trap where it is within reach for cleaning. Place 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.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all

leaks immediately.

WARNING: Never use an open ame to check for a leak. Apply a 50/50 mixture of liquid soap and

water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.

Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )

Fig. 20 - Gas Connection

The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).

Pressure Testing Gas Supply Equal To or less than 1/2 PSIG ( 3.5kPa )

The appliance must be isolated from the gas supply piping system by closing its equipment shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).

Leak Testing Heater Gas Internal Connections

1. Open equipment shutoff valve (See Fig. 21).

2. Make sure control knob of heater is in the OFF position.

3. Open gas supply tank valve (LP systems).

4. Check all joints from equipment shutoff valve to control valve. Apply 50/50 mixture of liquid soap and water to gas joints. If bubbles form, there may be a leak.

5. Light heater (see Operation, page 18). Check all other internal joints for leaks.

6. Turn off heater (see "To Turn Off Gas to Appliance," page 19).
