RHW-41/RHW-47 INSTALLATION INSTRUCTIONS

9. Mark the Exit Point of the Roof

Locate the point where the chimney will exit the roof by plumbing down to the center of the chimney. Drive a nail up through the roof to mark the center. See Figure 14.

10. Cut out the Hole in the Roof

Measure to either side of the nail and mark the 14-1/2 in. x 14-1/2 in.opening required. This is measured on the horizontal; actual length may be larger depending on the pitch of the roof. Cut out and frame the opening. See Chapter 25 of the Uniform Building Code for roof framing details.

Be sure to maintain a 2 in. minimum air space between the chimney section and the roof.

11.Assemble the Chimney Sections Through the Roof

Continue to add chimney sections through the roof opening, maintaining at least a 2 in. air space.

12. Install the Roof Flashing

If a roof flashing is to be used, install the roof flashing appropriate to the roof pitch and install a round termination cap following the instructions shipped with the cap.

For chase installations you can use a round termination cap (TR344), a round telescoping termination cap (TR342) or a square termination cap (ST375, TS345 or TS345P). A chase installation must use a chase top. Chase tops are available from your Heat-N-Glo distributor. See page 22 for building a chase.

13. Install the Outside Air Kit

The outside air kit is available for this fireplace. Its use is highly recommended to minimize the effects of negative pressure within the structure. It is recommended to utilize the shortest duct run to optimize the performance of the outside air kit. The outside air kit inlet thimble should be positioned at least 4 ft above the ground level, in a manner that will not allow snow, leaves, etc. to block the inlet.

The outside air kit is installed on the left hand side of the fireplace. Remove the cover plate from the side of the fireplace assembly where the air kit is to be installed. See Figure 15 for handle location/operation.

14.Install the Chimney Air Kit (required in Canada)

When installing the chimney air kit, follow the instructions provided with this accessory.

Caution:

The air kit handle may get hot while burning the fireplace. Use care when operating the handle.
