STR/CVR Series Woodburning Fireplaces Planning Information Preplanning an installation is very important to ensure safety and to save time and money. An installer must predetermine where a fireplace will be set and how the chimney system will be run. NOTE: STR33/36 and CVR36 models use CFM Corporation SK8 (2-wall) chimney systems. STR/CVR42 Fireplaces use only model 11CF chimney system. Mounting the Fireplace A fireplace may only be mounted on the following surfaces: 1. A flat combustible surface. 2.
STR/CVR Series Woodburning Fireplaces Installation Chimney Supports The chimney system is supported by the fireplace for vertical chimney heights less than 20' (6m) above the hearth. Chimney supports are required if the vertical height exceeds 20' (6m). Locate chimney supports at ceiling holes or other structural framing at 20' (6m) heights. Spacing between chimney supports must not exceed 20' (6m). Use Chimney Support Model SKCS8 for SK8 chimney, and Model 11CS for 11CF chimney.
STR/CVR Series Woodburning Fireplaces Chimney Set-up Framing Framing can be constructed before or after the fireplace is set in place, however, most installers build the frame before setting the fireplace. Frame fireplace with 2 x 4 lumber or heavier materials. Refer to framing dimensions in Figures 1, 2, 3 or 4 for basic fireplace specifications. Headers and support studs must be turned on end as illustrated on Page 5, Figure 4.
STR/CVR Series Woodburning Fireplaces Framing the Ceiling Hole Actual Centerpoint X Chimney Centerline Frame the ceiling chimney hole as shown in Figure 12. It is good practice to use framing lumber that is the same size as the ceiling joists; this is a requirement at attic level.
STR/CVR Series Woodburning Fireplaces Positioning, Safety Strips, Securing the Fireplace Slide fireplace into position. Lift the fireplace front slightly and slide the metal safety strips under front bottom edge about 1¹⁄₂" (38mm), allowing the remainder to extend in front of firebox. Overlap strips at least 1/2" (13mm) to provide a positive joint. (Flat safety strips are packed with fireplace.) (Fig.
STR/CVR Series Woodburning Fireplaces Installing the Chimney System Pipe Section Start by attaching the first chimney section to the collar on top of the fireplace. Pipe Rim UP Install the pipe as pictured in Figure 16. When you get a good lock, you will hear the pipe clearly snap together. Once sections are snap-locked in place, it is extremely difficult to get them apart. Make sure the pipe is firmly snapped and locked together as each pipe section is mounted.
STR/CVR Series Woodburning Fireplaces Firestop spacers are not available for nor are they required on vertical walls. DO NOT put any sealant around the area where the outer pipe slides through the firestop spacer. If you seal this area, it may cause a fire hazard. Attic Insulation Shield Nails (4 required) Canadian Requirements for Insulation Shield In Canada, an attic insulation shield is required to prevent attic insulation from contacting the chimney section.
STR/CVR Series Woodburning Fireplaces WARNING: DO NOT PACK REQUIRED AIR SPACES WITH INSULATION OR OTHER MATERIALS. Mark an outline of the roof hole around the center of the point nail. NOTE: Hole dimensions given in the chimney top installation instructions are horizontal dimensions; therefore, the hole size must be marked on the roof accordingly. Cover the opening of the installed chimney so debris cannot get into the system. Cut and frame the hole.
