High Altitude Installations

 

U.L. Listed gas appliances are tested and approved without requiring changes

 

for elevations from 0 to 2,000 feet in the U. S. A. and in Canada.

 

When installing this appliance at an elevation above 2,000 feet, it may be necessary

 

to decrease the input rating by changing the existing burner orifice to a smaller

 

size. Input rate should be reduced by 4% for each 1000 feet above a 2000 foot

 

elevation in the U.S.A. or 10% for elevations between 2000 and 4500 feet in

 

Canada. If the heating value of the gas has been reduced, these rules do not

 

apply. To identify the proper orifice size, check with the local gas utility.

 

If installing this appliance at an elevation above 4,500 feet (in Canada), check

 

with local authorities.

Getting

Started

7

Heat & Glo • ST-42TVFL-IPI455-902Rev. C • 12/07

When planning a fireplace installation, it’s necessary to determine:

Where the unit is to be installed.

The vent system configuration to be used.

Gas supply piping.

Electrical wiring.

Framing and finishing details.

Whether optional accessories—devicessuch as a fan, wall switch, or remotecontrol—aredesired.

If the fireplace is to be installed on carpeting or tile, or on any combustible material other than wood flooring, the fireplace should be installed on a metal or wood panel that extends the full width and depth of the fireplace.

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 & Glo assumes 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-TV air kit be used with this appliance.

!WARNING: IN A NEGATIVE PRESSURE CONDITION (LIKELY TO OCCUR IN NEW HOMES THAT DO NOT HAVE ADEQUATE MAKE-UPAIR) THE OUTSIDE AIR KIT MUST BE INSTALLED TO OBTAIN PROPER PERFORMANCE AND TO HELP PREVENT SPILLAGE OF COMBUSTION GASES.

A 4-inchdamper assembly (found inAK-TVKit) must be installed to the fireplace. See Figure 5. Attach the damper assembly to the outer wrap of the fireplace using sheetmetal screws

!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 required to first attach a straight section of vent to the unit before attaching a 90o elbow. Avoid using elbows in the vent system if possible.

A 90-degreeelbowCANNOT be attached directly to the unit.A 45o elbow can be attached directly to the unit. It must have a straight section of pipe attached to it for aMINIMUM of4-feetbefore a second 450 elbow to a horizontal run (see Figure 6). The horizontal component of the vent system must not exceed aMAXIMUM of17-feet.The vertical component of the vent system must exceed aMINIMUM of10-feet.Two 450 elbows to vertical can be used at any length within the17-feetmaximum horizontal component.

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

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. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter).

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 (13 mm) hook-upat the unit.

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

A listed (and the Commonwealth of Massachusetts approved) 1/2 inch (13mm) tee-handlemanual shutoff valve 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.

The gas line may be run from either side of the fireplace provided the hole in the outer wrap does not exceed 2 inches in diameter and it does not penetrate the airtight firebox.

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

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

Remove decorative door by lifting up away to gain access to the gas control and shut-offvalve, insert the gas supply line through the gas line hole, and connect it to theshut-offvalve.

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

After the gas line installation is complete, all connections must be tightened and checked for leaks with a commercially available, non-corro-sive leak check solution. Be sure to rinse off all leak check solution following testing.

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

Figure 13. Sealant Material

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.

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.

!WARNING: WHEN FINISHING THE FIREPLACE, NEVER OBSTRUCT OR MODIFY THE AIR INLET/OUTLET GRILLES IN ANY MANNER.

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 sheet rock and the fireplace.

Do not obstruct or modify the air inlet/outlet grilles. When overlapping on both sides, leave enough space so that the 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.

23

Heat & Glo • ST-42TVFL-IPI455-902Rev. C • 12/07

Save the remaining ember materials for use during fireplace servicing. The bag of embers provided is sufficient for 3 to 5 applications.

Replace the wing nut, glass clips and screws.

Replace glass door and a front trim door on unit.

Hand tighten the wing nut.

GLASS SPECIFICATIONS:

LARGE GLASS: TEMPERED

SMALL GLASS: TEMPERED

Heat & Glo fireplaces 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 ANSI Z97.1-1984and CPSC 16 CFR 1202. (Safety Glazing Certification Council SGCC # 1595 and 1597. Architectural Testing, Inc. Reports02-31919.01and 0231917.01.)

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.

Placing the Ember Material

Ember material is 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:

Remove wing nuts and glass clips or tension springs around glass door. Remove glass door from unit.

Place dime size pieces of ember material about 1/2 inch apart near port holes in burner top. Do NOT press embers into burner ports. Cover the top of the burner with a single layer of ember material. For best performance do NOT place embers on the ports at the rear of the burner.

Step 12

Before Lighting

the Fireplace

Step 13

Lighting the

Fireplace

After the

25 Installation

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

Remove all paperwork and documents 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 products used in the paint and logs.

During this break-inperiod it is recommended that some windows in the house be opened for air circulation. This will help avoid setting off smoke detectors, and help eliminate any odors associated with the fireplace’s initial burning.

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.

LEAVE THIS INSTALLATION MANUAL WITH THE APPLIANCE FOR FUTURE REFERENCE.
