Rheem RS47-21BP, RS80-42BP Roof Preparation, Supporting Structure installation

Page 19

Roof Preparation

This section contains instructions for correct installation of the system. Complete the procedures in the order listed.

NOTICE: The storage tank will be parallel to rafters of trusses for side- pitch mount and at a right angle for all other mounts.

NOTICE: Supporting rafters may be either 16” or 24” on center. Runners will not be equally spaced on 16” on-center rafters. See Figure for “Wood Runner Detail”.

NOTICE: Double check the placement of the runners over the rafters or trusses before drilling holes.

Refer to the checklist for necessary roof modifications on page 12.

Install supports for Fragile Tile Roof

The system may be installed directly on most roof types if the roof is in good condition with adequate drainage.

For other types of roofs, do the following:

Clear area of roofing material from top of roof to lower edge of roof with 2'

clearance on each side (refer to Figure below) set aside for reinstallation.

Install waterproof material over cleared area.

Fully seal and waterproof new material.

Fragile Tile Roof

Supporting Structure installation

NOTICE: You may want to pre- drill runners with pilot holes to avoid splitting runners with lag screws.

Refer to the appropriate section listed below for installation procedures:

•Standard Installation: Page 19

•Metal / Sturdy Tile Installation: Page 20

•Frame Installation: Page 21

Standard Installation

1.Mark supporting rafter/truss and bearing-wall locations on roof.

2.Place four 2" x 4" x 8' 4” redwood, treated-wood or Unistrut runners parallel down roof slope over marked rafters or trusses.

•For standard installation, runners must be placed within 3’ of roof ridge

•For roof-ridge mounts, place top of runners at roof ridge

3. Drill each runner in center and 6" from

runner ends and attach to rafters or trusses with 5/6" x 6" lag screws and washers.

4.Flash and seal all roof penetrations.

5.Position Collector Extrusion so that flat vertical edge is toward roof ridge

6.Level the Extrusion using a spirit level and shims After leveling, raise the hot pipe side of the extrusion by 1/2” per collector to ensure correct operation of the system (eg. For a 2 collector system, raise the hot pipe side of the extrusion by 1”).

7.Mount the Extrusion to each runner using 5/16" x 2” lag screws or Unistrut bolts.

8.Continue with Collector Installation, page 23.
