HEATING PERFORMANCE
Mendota Gas Built-in Fireplaces are true, high efficiency gas heaters. With its high heat output the Mendota Fireplace will heat a large area of your home if situated to maximize heat circulation. Air movement options for maximizing heat circulation which can be considered are through-the-wall grills or floor grills, the continuous operation of central heating furnace blowers, or ceiling fan. The most efficient method for overall heat distribution is a ceiling fan. The heat output of the
Fireplace can be reduced down to 22,500 BTUH by slowly turning the Hi/Lo temperature knob on the gas valve counter clockwise from "Hi" to "Lo". Further reduction of heat output, down to 7,500 BTUH, can be achieved by turning off the rear burner using the switch provided behind the lower grill. The blower can also be turned down to reduce heat output.
AESTHETIC CONSIDERATIONS:
Burning or static fireplaces are a major aesthetic focus in any room. Locate your gas fireplace as you would a television set. The Mendota Hearth Gas Fireplace will be a continuing source of comfort and fascination. Corner installations will afford you the greatest potential for viewing in many rooms.
HEARTH PROTECTION REQUIREMENTS: A non-combustible hearth protector is required and must extend a minimum of 14" in front of the fireplace (see Figure 1 on pg. 4 for raised hearths). We suggest installing the Mendota Fireplace 6 to
12 inches above the floor by utilizing an elevated hearth.
CAUTION: If you intend to install either the Andover Door Front or the Prairie Door Front on this fireplace, make certain that the top surface of the hearth protector is flush with the bottom surface of the fireplace, no higher. Failure to follow this guideline will prevent proper mounting and function of these two Fronts. See Page 16 for specific details.
ELECTRICAL REQUIREMENTS:
A blower kit is supplied as standard equipment on your Mendota Direct Vent Fireplace; A 120 volt electrical service must be supplied at the fireplace location at the time of installation. It must be electrically grounded in accordance with local codes or in their absence with current edition of the National Electric Code ANSI/NFPA 70. Power supply to blower must be continuous. DO NOT use a switch or variable control in power supplied to fireplace. Connect this 120 VAC supply line to e left side. CONNECT 120 VAC TO ONLY THE JUNCTION BOX INSTALLED ON THE LEFT SIDE OF THIS
APPLIANCE.
The blower kit in this appliance is equipped with a three-prong plug for protection against shock hazard and should be plugged directly into the grounded three-prong receptacle provided with the fireplace. Do not cut or remove the ground- ing prong from the plug.
NOTE: The blower output can be adjusted with the remote control transmitter. There will be delays in blower operation during "heat-up" (approx. ½ hr.) and extended blower operation during "cool-down" (approx. ½ hr.) of unit .
Wall Thermostats are NOT recommended for this appliance. A Thermostatic Remote Transmitter is supplied with this appliance. Consult your dealer or the Mendota Service Department if you wish otherwise.
