Page 6: General Installation Information
GENERAL INSTALLATION INFORMATION In planning the installation for the appliance it is necessary to determine where the unit is to be installed and whether optional accessories are desired. Gas supply piping should also be planned. The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence. 1. Position firebox prior to framing or into prepared framing. 2. Field wire main power supply to models with fan kit. (Electrical connections should only be performed by an experi- enced, licensed /certified tradesman). 3. Plumb gas line. (Gas connections should only be performed by an experienced, licensed/certified tradesman). 4. Install vent-free gas log heater per the instructions provided with the vent-free gas log heater. 5. Complete finish wall material, surround and optional hearth extension to your individual taste. FIREBOX DIMENSIONS 36MCUFD 42MCUFD " 47" 6" 4" " " " 8" " " " " " " 5.25"... -

Page 8: Clearances And Height Requirements
CLEARANCES HEIGHT REqUIREMENTS Ensure that minimum clearances shown in Figures 4 through 7 are maintained. Left and right clearances are determined when facing the front of the firebox. " Follow these instructions carefully to ensure safe installation. Failure n i m to follow these requirements may create a fire hazard. Sidewall clearances: The clearance from the inside of the 6 " n i m appliance to any combustible wall should not be less than 6". See Figure 4. Ceiling clearance: The ceiling must be at least 42” from the 6 " n i m top of the firebox opening. See Figure 4. 3. Back wall clearance: The appliance may be placed against a combustible back wall. -

Page 10: Fireplace Framing
FIREPLACE FRAMING Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following Figures 9 through 12 and the chart below for your specific installation requirements. See Figure 1 on Page 6 for firebox dimensions. The framing headers may rest on the top of the firebox standoffs. The firebox may be installed directly on a combustible floor or raised on a platform of an appropriate height. When the firebox is installed directly on carpeting, tile, or other combustible material, other than wood flooring, the firebox shall be installed on a metal or wood panel extending the full width and depth of the enclosure. Combustibles may not come any closer to the top of the enclosure than the standoffs will allow. Do not fill spaces around firebox with insulation or other materials. This could cause a fire. -

FIREPLACE FRAMING When finishing a custom cabinet, mantel, or other built-in enclosure, the opening size to accommodate the fireplace with trim installed is as follows: 36MCUFD MCUF42 with Trim with Trim K 4" " " " Figure 13 - Custom Cabinet the fireplace must be installed giving full consideration to the clearance and height requirements identified in this manual. 1. Bend out the nailing flanges located on each side of the firebox. 2. Slide the firebox into prepared framing or position firebox in its final position and frame later. -
Page 12: Gas Line Installation

Consult all local codes. All gas piping must be installed to comply with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code ANSI Z223.1/NFPA54. Remove the baseplate for ease of gas line installation. Remove three (3) screws along the front edge of the baseplate. Remove four (4) screws which secure the baseplate to the combustion casing (two at rear and one along each side). Replace baseplate prior to connecting gas line to heater. Consult heater installation and operating instructions for correct installation of the heater into the firebox. The " gas line may enter either from the left side or right side of the firebox. Gas access holes are provided on both sides of the firebox. A listed manual shutoff valve must be installed upstream of the appliance. A union tee and plugged " NPT pressure tapping point should be installed upstream of hte appliance. -

Page 16: Using Optional Outside Air Kit
USING OptIONAL AK-4 OUtSIDE AIR KIt COMBUSTION AIR 1. Locate combustion air assembly at an exterior location which is not likely to be accidentally blocked in any manner. Locate assemblya min. of 12" above the snow line to prevent blockage by snow accumulation. 2. Never mount the combustion air inlet assembly in a garage or storage area where combustible fumes such as gasoline might be drawn into the fireplace. 3. Combustion air can be drawn from the crawl space under a house when an adequate supply of air is provided by open ventilation. 4. CAUTION: Do not take combustion air from attic space or garage space. 5. Locate air supply inlet at least 3' away from any applaince vent terminal. 6. Avoid extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air assembly. These conditions increase the resistance to the free flow of air through the duct. See Figures 17 through 20 for methods of installing the outside air for combustion assemblies. Firestop Spacer Note: Fireplace model in illustrations may not be representative of your appliance. - Page 17 USING OptIONAL AK-4 OUtSIDE AIR KIt The use of outside air for combustion is optional unless required by building codes. It is only necessary to supply outside combustion air to one side of the fireplace. Use the model AK4 combustion air kit. MODEL AK-4 COMBUStION AIR ASSEMBLy DO NOT remove the 1.
