M = Clearance under veranda, porch, deck, or balcony 12 Inches (30 cm) permitted only veranda, porch, deck, or balcoopen on a minimum of two sides n . In accordance with the current CSA-B149.1 Natural Gas and Propa Page 4 CLEARANCES 1. The minimum clearance to a side wall is 4”. (See Fig. 1). NOTE: The unit may be recessed and rest directly against side studs and the inside surface of the rear wall. 2. The minimum clearance to the ceiling is 4”. (See Figure 1). 3. The minimum clearance to the floor is 0”. (See Figure 1). 4. The minimum clearance from the side of the vent cap to any protruding obstructions, or corners is 12”. (See Figure 2b). 5. The minimum clearance from any window to the side of the vent cap is 9” for DVCF403, 404, 407 and 408 (See Figure 2), and 12” for DVCF557, 558, 653, and 654 (See Figure 2b). 6. The minimum clearance from any overhanging projection is 24” to top of vent cap (See Figure 2). 7. RESIDENTIAL GARAGE INSTALLATION: Gas utilization equipment in residential garages shall be installed so that all burners and burner ignition devices are located not less than 18 inches (46 cm) above the floor. Such equipment shall be located, or protected so it is not subject to damage by a moving vehicle. Use care in selecting a good location within the garage. DO NOT locate the appliance where heated air will be directed onto a nearby parked vehicle. Paint may discolor or rubber may harden and crack. DO NOT allow heated discharge air to blow directly onto open or closed containers of paint, gasoline or other liquids having flammable vapors. 24” Min. 12” Min. 12” Min. 9” Min.

This furnace must be installed on an outside wall and vented to the outside. If possible, this wall should be on the side of the house that receives the least amount of wind since strong gusting winds could cause pilot outage. 2. For most efficient performance, locate furnace as centrally as possible in the area to be heated. 3. The furnace can be installed flush against a wall or recessed up to 10” maximum. For proper combustion, make sure unit is level front to back and side-to-side. 4. Do not install the furnace in a closet, alcove or small hallway where the furnace could be isolated from the space to be heated by closing a door. 5. Be sure the vent cap will have the proper clearances (See Figure 2). 6. Check inside the wall to make sure there are no obstacles such as water pipes, electric wiring, etc. which could interfere with the installation of the furnace or vent tubes. 7. Be sure to maintain adequate accessibility clearances for servicing and proper operation. 8. If the furnace is installed in a basement, a 12” clearance must be maintained between ground level and the bottom of the vent cap. Do not install furnace where vent cap will terminate in a window well or any other opening below ground level. INSTALLATION ELECTRICAL ROUGH-IN For convenience, this furnace is equipped with a three-prong power cord located on the top left of heater. The 115V wiring should be brought in on the left side terminating in a receptacle box (not provided). Consult local codes or ordinances. (For Amps, see Page 2/Specifications and Dimensions). ROUGH-IN GAS SUPPLY Install a 1/2 inch diameter gas supply line. The gas line can enter the cabinet through the right side or bottom (See Figure 3). The gas line must have an individual manual shut off valve. Also, you must install a drip leg and provide a 1/8” N.P.T. plugged tapping, accessible for test gauge connection, immediately upstream of the gas supply connection to the furnace (See Figure 4). The furnace and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of . psig (3.5kPa). The furnace must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than . psig (3.5kPa).

WALL STUDS DVCF40 -59” DVCF55/65 - 68-1/2” FINISHED FLOOR FIGURE 5 LOCATE VENT OPENING After the location of the heater has been determined, the opening for the vent pipe should be cut. If the heater is to be recessed, cut out opening for heater between studs on the interior wall and cut out the floor plate between the studs, so heater will set flat on floor as all dimensions are given from a finished floor. The height of the cut out for a 40,000 BTU model is 78-5/8”, for the 55,000 and 62,500 models the cut out height is 87-5/16”. NOTE: This dimension may be increased to allow more room for installation and making the wi...
