1 Listing and Code Approvals

A. Appliance Certification

MODELS: MTL-INSERT

LABORATORY: Underwriters Laboratories, Inc. (UL)

TYPE: Vented Gas Fireplace Heaters

STANDARD: ANSI Z21.88a-2007/CSA 2.33a-2007

ANSI Z21.88-2005/CSA 2.33-2005

This product is listed to ANSI standards for “Vented Gas Appliance Heaters” and applicable sections of “Gas Burn- ing Heating Appliances for Manufactured Homes and Recreational Vehicles”, and “Gas Fired Appliances for Use at High Altitudes”.

NOT INTENDED FOR USE AS A PRIMARY HEAT SOURCE. This appliance is tested and approved as either supplemen- tal room heat or as a decorative appliance. It should not be factored as primary heat in residential heating calculations.

Note: To assure top performance, safety and efficiency, inserts must be installed with an approved flue liner as per CAN/CGA B-149 or National Fuel Gas Code ANSI Z223 and these instructions.

Note: This installation must conform with local codes. In the absence of local codes you must comply with the National Fuel Gas Code, ANSI Z223.1-latest edition in the U.S.A. and the CAN/CGA B149 Installation Codes in Canada.

C. High Altitude Installations

U.L. Listed gas appliances are tested and approved with- out requiring changes for elevations from 0 to 2000 feet in the U.S.A. and Canada.

When installing this appliance at an elevation above 2000 feet, it may be necessary to decrease the input rat- ing 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 4500 feet (in Canada), check with local authorities.

WARNING

Do NOT use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.
