1Approvals and Codes

Appliance Certification

The Heat-N-Glofireplace model discussed in thisInstallers Guide has been tested to certification standards and listed by the applicable laboratories.

Certification

MODEL: ST-38GTV

LABORATORY: Warnock Hersey Listed

TYPE: “B” Vent Decorative

STANDARD: ANSI Z21.50•CGA2.22

Installation Codes

The fireplace installation must conform to local codes. Before installing the fireplace, consult the local building code agency to ensure that you are in compliance with all applicable codes, including permits and inspections.

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.
