II. Installation Instructions
DETERMINE BEST MOUNTING LOCATION for boiler which meets site requirements outlined in Section I, pages 4 through 6.
1INSTALLING BOILER MOUNTING WALL BRACKET (See Figure 5).
a.Locate wall bracket packed in miscellaneous parts carton.
b.Hold wall bracket in desired location. On studded walls, mounting bracket must be secured directly to main vertical support studs. Interior wall coverings such as paneling, plaster and drywall are not suitable to support the unit’s weight. Place a 24” level across top corners, adjust wall bracket until level. Using the wall bracket as a template, mark the eight
(8) securing holes along the sides and the 4½” x 5¼” rectangular opening at the top. Remove wall bracket from wall.
NOTE: The boiler mounting wall bracket is suitable for two main methods of wall construction.
c.Drill eight (8) pilot holes, properly sized for the fastener determined suitable for the type of wall construction in the area where the boiler is to be mounted (i.e., lag screw for wood, machine screw with toggle for cinder block, etc.).
d.Before cutting rectangular opening on interior wall, use a straight edge to draw an “X” inside the box using the four (4) corners. Drill a hole in the center of the “X” straight through the wall to the outside. On the exterior wall draw a 4½” x 5¼” rectangular box centered around the reference hole which matches the rectangular box on the interior wall.
e.Cut along outside edge of lines on interior and exterior surfaces of the wall and remove all material within the rectangular box. Check the wall penetration by inserting
f.Lay the wall bracket face down. Apply a ¼” thick bead of silicone rubber type caulking around the rectangular opening approximately 1” from the edge.
g.Reposition boiler mounting wall bracket on wall, using a 24” level across top corners, level wall bracket and secure to wall with suitable fasteners.
h.Attach lower R.S. jacket mounting bracket to right side of boiler mounting wall bracket with sheet metal screws provided. (See Figure 5)
2INSTALLING BOILER AND INTERIOR TELESCOPING INTAKE AIR DUCT (See Figure 5)
a.Separate two halves of telescoping intake air duct. Interior half of duct has a 1” wide rectangular gasket flange with four (4) weld studs for attaching to back plate of boiler. Exterior half of duct has the 9” square stainless steel wall flange for securing to exterior wall. (See Figure 5)
NOTE: 1. Standard telescoping intake air duct, part No. 6110301, is for wall thickness from 5” to 9”.
NOTE: 2. Optional telescoping intake air duct, part No. 6110302, is for wall thickness from 9” to 15”.
b.Insert interior half of duct into rectangular opening and push it all the way back against wall plate.
c.Place 6” x 7” rectangular gasket on interior duct flange and ¼” weld studs.
d.Remove boiler from packaging.
1.Remove surrounding packaging material from boiler and skid.
2.Remove screws holding enclosure cover.
3.Remove enclosure cover.
4.Locate and remove two (2) lag screws which secure back plate of boiler to skid. One is located in the upper left corner of the controls area and the second one is located in the lower right corner under the gas burner.
5.Remove boiler from skid and set unit upright on floor in front of installation site.
NOTE: On the back plate of the boiler is a “Z” bracket approximately 10” long. When the boiler is lifted into place, this bracket must be lowered into the ½” wide x 11” long slot at the top of the boiler mounting wall bracket. (See Figures 4 and 5)
e.Attach upper RS jacket mounting bracket to the upper corner of back plate. Loosen the two (2) corner screws, position bracket with flange facing forward and engage slots over screws.
f.Lift boiler up into position. Make sure that “Z” bracket is properly engaged into slot and is resting on ¼” wide flange in front of slot before releasing the weight of the boiler.
g.Move boiler slightly to the left or right to align the five (5) clearance holes in the back plate with the fasteners on boiler mounting wall bracket.
