QUALIFIED INSTALLING AGENCY

Only a qualied agency should install and replace gas piping, gas utilization equipment or accessories, and repair and equipment servicing. The term “qualied agency” means any individual, rm, corporation, or company that either in person or through a representative is engaged in and is responsible for:

a) Installing, testing, or replacing gas piping

or

b) Connecting, installing, testing, repairing,

or servicing equipment; that is experienced

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 KWs) of gas input per hour. Unvented room heaters are recommended as supplemental heat (a room) rather than a primary heat source (an entire house). 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.

AIR FOR COMBUSTION AND VENTILATION

in such work; that is familiar with all precautions required; and that has complied with all the requirement of the authority having jurisdiction.

In areas that prohibit the use of vent-free heaters, the log set has been tested and approved to the ANSI Z21.60 standard for Vented Decorative Logs. When used as a vented log set refer to additional instructions on page 11.

The following steps will help ensure that water vapor does not become a problem.

1. Be sure the heater is sized properly for the application, including ample combustion air and circulation air.

2. If high humidity is experienced, 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.

WARNING: 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. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today’s homes are built more energy efcient 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.

www.usaprocom.com

While it is good to make your home energy efcient, 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, replaces, 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.

WARNING: 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, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.

200068-01A6

AIR FOR COMBUSTION AND VENTILATION

Ventilation

WARNING: If the area in which

the heater may be operated does not meet the required volume for indoor combustion air, combustion and ventilation air shall be provided by one of the methods described in the National Fuel

Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconned space. When ventilating to an adjoining unconned space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the oor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI

Z223.1/NFPA 54, 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 ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" 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, ANSI Z223.1/NFPA 54, 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. If an attic opening is unacceptable. Recongure the conned space, by adding ventilation to adjoining unconned space or removing doors as indicated in Figure 2, Option 1 and 2. The combined spaces must have enough fresh air to supply all appliances in both spaces. Otherwise a lower input model must be installed that meets the room size requirements.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED

OPERATION

When used as a vented heater, appliance must be installed only in a solid-fuel burning replace with a working ue constructed of noncombustible material. You may use this heater as a vented product. There are three reasons for operating your heater as a vented model:

1. The replace does not meet the clearance requirements for vent-free operation.

2. State or local codes do not permit ventfree operation.

3. You prefer vented operation.

If reasons number 1 or 2 above apply, you must permanently open chimney ue damper. You must install the damper clamp accessory (not provided). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.

See chart below for the minimum permanent ue opening you must provide. Attach damper clamp so the minimum permanent opening will be maintained at all times.

B. If combustible materials are less than 14"

to the replace, you must install appliance at least 5" above the combustible ooring (see Figure 9).

CONNECTING TO GAS SUPPLY

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

WARNING: This appliance requires a 1/2" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: Do not overtighten gas connections.

WARNING: For natural gas, Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

CAUTION: For propane/LP gas, never connect heater directly to the gas supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/ LP supply. Gas supplier provides external regulator for natural gas. The installer provides the external regulator for propane/LP gas.

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" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

CAUTION: For natural gas, check your gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5" WC. If gas line pressure is higher, heater regulator damage could occur.

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/LP or Natural Gas).

Before installing heater, make sure you have the items listed below:

• external regulator for propane/LP unit only (supplied by installer)

• piping (check local codes)

• sealant (resistant to natural gas and propane/LP gas)

• equipment shutoff valve*

• test gauge connection*

• sediment trap

• tee joint

• pipe wrench

INSTALLATION

Typical Inlet Pipe Diameters

Use 1/2" black iron pipe or greater. Installation must include an 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).

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.

For propane/LP installations, 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.

The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" WC and 14" WC. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 14. Pointing the vent down protects it from freezing rain or sleet.

Install sediment trap in supply line as shown in Figure 13. 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.

OPTIONAL POSITIONING OF THERMOSTAT SENSING BULB

For masonry and factory-built metal replace

If your log set cycles to pilot, but the room temperature drops to a lower than ideal comfort level before the log set comes back on, you may want to reposition the thermostat sensing bulb.

The thermostat sensing bulb is located near the gas valve assembly on the mounting bracket. This location allows the thermostat

www.usaprocom.com

to keep the room temperature at an ideal comfort level for most replace applications. For positioning the thermostat sensing bulb elsewhere, a mounting clip is available.

Tools needed: 1/4" hex driver or socket.

1. Remove logs. Locate the gas valve assembly and thermostat sensing bulb.

200068-01A16

INSTALLATION

2. Remove the thermostat sensing bulb out of the plastic clip (see Figure 22).

IMPORTANT: Do not force or bend the thermostat sensing bulb or capillary.

3. The thermostat sensing bulb may be located to the lower right front side of replace. Determine location of sensing bulb, but do not mount sensing bulb until step 5. If you have a masonry replace, (see Figure 21 for location). If you have a factory-built metal replace, see Figure 20 for location. If your replace has glass doors, position sensing bulb directly behind door gap on right bottom side (see Figure 23).

4. The mounting clip must be a minimum of 3" from bottom of replace to prevent crimping of capillary. Once you have decided on a location, thoroughly clean the area. Remove the paper backing from the adhesive on back of mounting clip (provided with the heater in hardware package) (see Figure 19). Press the clip into the new location so that the thermostat sensing bulb will be positioned vertically with the capillary at the bottom (see Figure

24). Slide the thermostat sensing bulb into the clip.

INSPECTING BURNERS

Approx. 3"-6" Above Top of Logs

IMPORTANT: Owner’s should check pilot ame pattern and burner ame pattern often. Incorrect ame patterns indicate the need for cleaning (see Care and Maintenance,

page 24) or service.

WARNING: Only a qualied service person should service and repair heater. This includes maintenance requiring replacement or alteration of components.

PILOT FLAME PATTERN

Figure 31 shows a correct pilot ame pattern. Figure 32 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool, which shuts the heater off.

If pilot ame pattern is incorrect, as shown in Figure 32

• turn heater off (see To Turn Off Gas to Ap- pliance, page 21 or 22)

• see Troubleshooting pages 25 through 28.

Notice: Do not mistake orange ames with yellow tipping. Dirt or other ne particles enter

the heater and burn causing brief patches of

orange ame.

HLA Model Shown

BURNER INJECTOR HOLDER AND 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. Your 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 and primary air inlet holes on injector for dust and dirt (see Figure 35).

ODS/PILOT

Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.

A yellow tip on the pilot ame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about 2" from where the pilot ame comes out of the pilot assembly (see Figure 36). 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.

• If you remove logs for cleaning, refer to Install-

ing Logs, page 18, to properly replace logs.

www.usaprocom.com

burner ame holes may become blocked by debris or rust, with no ame present. If so, turn off the heater and let it cool, and remove blockage. Blocked burner ame holes will create soot.

3. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly.

4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.

5. Blow air into the primary air holes on the injector holder.
