In the absence of local codes, the fireplace installation must conform to the National Fuel Gas Code ANSI Z223.1 (in the United States) or the CAN/CGA-B149Installation Codes (in Canada). The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes with the National Electric Code ANSI/NFPA No. 70 (in the United States), or to the CSAC22.1 Canadian Electric Code (in Canada).

This model (natural gas and propane) can be installed in a bedroom (in the United States) which has a total volume of unconfined space appropriate to the particular installation. Refer to the National Fuel Gas Code ANSI Z223.1/NFPA54 (current edition). The Uniform Mechanical Code - (current edition), and local Building Officials for the options allowed in obtaining an effective bedroom volume of unconfined space.

This model (natural gas and propane) can be installed in a bedroom (in Canada) if a thermostat (Model WH-STAT)is installed with the unit. Consult local code authorities. Detailed installation instructions for ModelWH-STATare included with the kit.

High Altitude Installations

Warnock Hersey Listed gas fireplaces are tested and approved for elevations from 0 to 2,000 feet in the U.S.A. and from 0 to 4,500 feet in Canada.

When installing this fireplace at an elevation above 2,000 feet (in the United States), it may be necessary to decrease the input rating by changing the existing burner orifice to a smaller size. Input should be reduced four percent (4%) for each 1,000 feet above sea level, unless the heating value of the gas has been reduced, in which case this general rule will not apply.

When installing this fireplace at an elevation between 2,000 and 4,500 feet (in Canada), the input rating must be reduced by ten percent (10%).

When installing this fireplace at an elevation above 4,500 feet (in Canada), check with local authorities.

Consult your local gas utility for assistance in determining the proper orifice for your location.

Step 3. Negative Pressure Make-upAir

Negative Pressure warning: When negative pressure is present, an atmospherically vented fireplace (with a draft hood) may not function properly and it may down draft. In the case of a gas appliance, spillage of the combustion gases may occur.This may create a dangerous carbon monoxide situation in the house.

The causes of negative pressure to a house can include the following:

Stack effect in the building.

Exhaust only appliances (mechanically and atmospherically vented).

Inadequate make-upair (which is increasingly more prevalent in new construction).

NOTE: This fireplace will operate correctly only if adequate ventilation is provided to allow proper draft to the fireplace system.Heat-N-Gloassumes no responsibility for the improper performance of the fireplace system caused by inadequate draft due to environmental conditions, down drafts, tight sealing construction of the structure, or mechanical exhausting devices which create a negative air pressure within the structure where the fireplace is located.

It is recommended that all natural venting non-airtight gas fireplaces have outside air connected to them. It is also recommended that the building be mechanically or passively balanced to allow atmospherically vented appliances, such as top vented gas fireplaces with draft hoods, to draft properly. If the home experiences negative pressure or is likely to experience negative pressure, connection to an outside air source is mandatory.

Installing Optional Outside Make-upAir:This unit is equipped to accept outside air. By using outside make-up air, the amount of room air used for combustion will be reduced. It is recommended that an AK-225 air kit be used with this appliance.

!WARNING: IN A NEGATIVE PRESSURE CONDITION (LIKELY TO OCCUR IN NEW HOMES

THAT DO NOT HAVEADEQUATE MAKE-UPAIR)THE OUTSIDE AIR KIT MUST BE INSTALLED TO OBTAIN PROPER PERFORMANCEAND TO HELP PREVENT SPILLAGE OF COMBUSTION GASES.

A 4-inchside collar and a4-inchflexible air duct must be installed to the outer wrap of the fireplace. See Figure 4. After removing and discarding the outside air cover plate attach the side collar to the outer wrap of the fireplace using sheetmetal screws. Attach one end of the flex duct to the side collar and the other end of the duct to the termination cap. Use plastic tie straps to secure the ends of the flex duct to the collar.

Detailed installation instructions for Model AK-225Outside Air kit are found in the kit. This kit cannot be used in Canada.

Step 4. Installing the Vent System

A. Vent System Approvals

Model ST-38GTVis approved to use5-inch(127mm) diameterB-typevent.B-typevent must be used when the vent system is within combustible construction.

This model may also use single wall rigid or flexible gas vent IF andONLY IF the vent system is installed withinnon-combustibleconstruction such as a masonry chimney. The same diameter noted above forB-typevent must be used forsingle-wallvent. See Figure 5.

B. System Components.

Vent System Configuration

MAXIMUM TOTAL HORIZONTAL RUN = 13 FT.

MAXIMUM TOTAL VERTICAL RISE = 10 FT.

MAXIMUM NO. of ELBOWS: 2-90o plus 4 - 45o, or 8 - 45o.

Plan and install the vent system using the parameters shown above.

!WARNING: YOU MUST NOT EXCEED THESE PARAMETERS.

Connect a B-Typevent component to the flue outlet collar. Look at top inside of the firebox to check that the vent pipe is attached to the unit.NOTE: It is always better to first attach a straight section of vent to the unit before attaching an elbow. Avoid using elbows in the vent system if possible.

A 90-degreeelbow can be attached directly to the unit. If it is, it can be followed by aMAXIMUM 13-feethorizontal run, a second90-degreeelbow ending in a vertical position, and aMINIMUM 10-feetvertical rise ending in a listed termination cap for the vent pipe.

Continue to add vent components, until the vent run is completed.

!WARNING: YOU MUST NOT EXCEED A TOTAL MAXIMUM HORIZONTAL RUN OF 13 FEET FOR THE ENTIRE VENT SYSTEM AND THERE MUST BE A TOTAL VERTICAL MINIMUM RISE OF 10FEET INALL VENT SYSTEM CONFIGURATIONS USED ON THESE FIREPLACES.

NOTE: The vent termination must be in a vertical position and the termination cap must be listed for the vent pipe used.

Consult Local Building Code Officials and Codes for proper vent system installations.

Figure 8. Gas Supply Line

 

Step 7. The Gas Supply Line

NOTE: Have the gas supply line installed in accordance with local building codes by a qualified installer approved and/or licensed as required by the locality.

NOTE: Before the first firing of the fireplace, the gas supply line should be purged of any trapped air.

NOTE: Consult local building codes to properly size the gas supply line leading to the 1/2 inch (13mm) hookup at the unit.

This gas fireplace is designed to accept a 1/2 inch (13mm) gas supply line.

To install the gas supply line:

A listed (and State of Massachusetts approved) 1/2 inch (13mm) tee-handlemanualshut-offvalve and a listed flexible gas connector are connected to the 1/2 inch (13mm) inlet of the control valve.NOTE: If substituting for these components, please consult local codes for compliance.

Locate the gas line access hole in the outer casing of the fireplace.

The gap between the supply piping and gas access hole can be plugged with non-combustibleinsulation to prevent cold air infiltration.

Insert the gas supply line through the gas line hole, and connect it to the shut-offvalve.

When attaching the pipe, support the control so that the lines are not bent or torn.

After the gas line installation is complete, use a soap solution to carefully check all gas connections for leaks.

!WARNING: DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

At the gas line access hole, use insulation to re-packthe space around the gas pipe.

Insert insulation from the outside of the fireplace and pack the insulation tightly to totally seal between the pipe and the outer casing.

Hearth Extensions

A hearth extension may be desirable for aesthetic reasons. However,ANSI or CAN/CGAtesting standards do not require hearth extensions for gas fireplace appliances.

Step 11. Installing Trim, Logs & Ember Material

Installing the Trim

Combustible materials may be brought up to the specified clearances on the side and top front edges of the fireplace, but MUST NEVER overlap onto the front face. The joints between the finished wall and the fireplace top and sides can only be sealed with a 300° F. (149° C) minimum sealant.

Install optional marble and brass trim surround kits as desired. Marble, brass, brick, tile, or other non-combustiblematerials can be used to cover up the gap between the sheetrock and the fireplace.

Do not obstruct or modify the air inlet/outlet grilles. When overlapping on both sides, leave enough space so that the controls can be accessed and the trim door and glass door can be removed.

Positioning the Logs

If the gas logs have been factory installed they should not need to be positioned.

If the logs have been packaged separately, refer to the installation instructions that accompany the logs. Save the log instructions with this manual.

If sooting occurs, the logs might need to be repositioned slightly to avoid excessive flame impingement.

Placing the Ember Material

Two separate bags of ember material are shipped with this gas fireplace:

The bag labeled Golden Ember (GE-93)is flame colorant material.

The bag labeled Glowing Ember (050-721)is standard glowing ember material.

To place the ember material:

Lift the trim door up and out from the unit.

Remove the wing nuts and screws around the glass door.

TEMPERED

Heat-N-Glofireplaces manufactured with tempered glass may be installed in hazardous locations such as bathtub enclosures as defined by the CPSC. The tempered glass has been tested and certified to the requirements of ANSIZ97.1-1984and CPSC 16 CFR 1202. (Safety Glazing Certification Council SGCC # 1595 and 1597. Architectural Testing, Inc. Reports02-31919.01and02-31917.01.)

This statement is in compliance with CPSC 16 CFR Section 1201.5 “Certification and labeling requirements” which refers to 15 USC 2063 stating “…Such certificate shall accompany the product or shall otherwise be furnished to any distributor or retailer to whom the product is delivered.”

Some local building codes require the use of tempered glass with permanent marking in such locations. Glass meeting this requirement is available from the factory. Please contact your dealer or distributor to order.

Step 12. Before Lighting the Fireplace

Before lighting the fireplace, be sure to do the following:

Remove all paperwork from underneath the fireplace. Review safety warnings and cautions

Read the Safety and Warning Informationsection at the beginning of this Installers Guide.

Double-checkfor gas leaks

Before lighting the fireplace, double-checkthe unit for possible gas leaks.

Double-checkvent terminations and front grilles for obstructions.

Before lighting the fireplace, double-checkthe unit for possible obstructions that could be blocking the vent terminations or the front grilles.

Double-checkfor faulty components

Any component that is found to be faulty MUST BE replaced with an approved component. Tampering with the fireplace components isDANGEROUS and voids all warranties.

A small amount of air will be in the gas supply lines. When first lighting the fireplace, it will take a few minutes for the lines to purge themselves of this air. Once the purging is complete, the fireplace will light and will operate normally.

Subsequent lightings of the fireplace will not require this purging of air from the gas supply lines, unless the gas valve has been turned to the OFF position, in which case the air would have to be purged.

NOTE: The fireplace should be run 3 to 4 hours on the initialstart-up.Turn it off and let it cool completely. Remove and clean the glass. Replace the glass and run the fireplace for an additional 8 hours. This will help to cure the chemicals used in the paint and logs.

Step 13. Lighting the Fireplace

You’ve reviewed all safety warnings, you’ve checked the fireplace for gas leaks, you know the vent system is unobstructed, and you’ve checked for faulty components. Now you’re ready to light the fireplace.

!WARNING: PLEASE REFER TO THE USER’S MANUAL FOR ALL CAUTIONS, SAFETY, AND

WARNING INFORMATION PERTAINING TO THE LIGHTING AND OPERATION OF THE FIREPLACE.

After the Installation

!LEAVE THIS INSTALLATION MANUAL WITH THE APPLIANCE FOR FUTURE REFERENCE.

4Maintaining and Servicing Your Fireplace

Fireplace Maintenance

Although the frequency of your fireplace servicing and maintenance will depend on use and the type of installation, you should have a qualified service technician perform an appliance check-upat the beginning of each heating season. See the table below for specific guidelines regarding each fireplace maintenance task.

IMPORTANT: TURN OFF THE GAS BEFORE SERVICING YOUR FIREPLACE.

Replacing old ember material

Frequency: Once annually, during the checkup.By: Qualified service technician.

Task: Brush away loose ember material near the burner. Replace old ember material with newdime-sizeand shape pieces of Golden Ember(DE-93)and Glowing Ember (050721). New ember material should be placed alternately on top of the burner - a layer of Golden Ember, a layer of Glowing Ember, and so on. Save the remaining ember material and repeat this procedure at your next servicing. For more information, seePlacing Ember Material.

Cleaning Burner and Controls Frequency:Once annually. By:Qualified service technician.

Task: Brush or vacuum the control compartment, fireplace logs and burner areas surrounding the logs.

Checking Flame Patterns, Flame Height Frequency:Periodically.

By: Qualified service technician/Home owner.

Task: Make a visual check of your fireplace’s flame patterns. Make sure the flames are steady - not lifting or floating (see Figure 17). The flame sensor (DSI) or thermopile (standing pilot) tips should be covered with flame (see Figure 8).

Figure 17. Burner Flame Patterns

Checking Vent System

Frequency: Before initial use and at least annually thereafter, more frequently if possible.

By: Qualified service technician/Home owner.

Task: Inspect the external vent cap on a regular basis to ensure that no debris is interfering with the flow of air. Inspect entire vent system for proper function.

Cleaning Glass Door

Frequency: After the first 3 to 4 hours of use. As necessary after initial cleaning.

By: Home owner.

Task: Remove and clean glass after the first 3 to 4 hours of use. After the initial cleaning, clean as necessary, particularly after adding new ember (flame colorant) material. Film deposits on the inside of the glass door should be cleaned off using a household glass cleaner.NOTE: DO NOT handle or attempt to clean the door when it is hot and DO NOT use abrasive cleaners.
