Dacor REMP3 Installation Instructions - Page 7

Installation Planning and Preparation Blower Location and Mounting (cont.) • Select a location that can properly support or can be reinforced to support the weight of the blower (see weight table below). The unit requires a mounting surface around the perimeter of the base of the unit 2" in width and thick enough to accommodate the 8, 2 1/2" long mounting screws that are provided with the unit. All contact surfaces between the blower and any mounting surfaces must be solid and at right angles. See Figure 1 for the required mounting surface dimensions. Model Number REMP3 REMP16 Approximate Shipping Weight 35 lbs. 55 lbs. Weight Table A E C D F B • The blower must also be mounted vertically or at a pitch of 2:12 or greater. If the pitch of the mounting surface is less than 2:12, construct a roof curb to mount the blower. See Installation Preparation for exact dimensions. • When mounted in a exposed location shield it to prevent the accumulation of water in the chassis. On horizontal installations, point the discharge in the same direction as prevailing winds. When mounted vertically, the discharge must point down. Prevailing Wind Roof Curb Blower Discharge Figure 2: Installation with Roof Curb (for flat roofs) Installation Preparation 1. Prepare the mounting surface and reinforce it if necessary according to the Blower Location and Mounting specifications starting on page 4. 2. Make a cutout in the center of the mounting location according to Figure 1. 3. On roofs with a pitch of 2:12 or less, construct a roof curb according to the specifications below. Attach it to the mounting surface and seal it around the base.
