Lower carriage bolt until threaded end will pass through hole in bracket. Secure canopy with ¼” ﬂat washers, lock washers and brass nuts. See Figure 18.

13.Attach the 1/8” x 1” wide self-adhesive ﬁber gasket to the surfaces of either the top ﬂue outlet damper assembly or top outlet canopy cover that mounts against the canopy. Gasket must be centered over all attachment holes. Do not overlap corners, cut butt joints.

14.Secure either the top ﬂue outlet damper assembly or top outlet canopy cover with #10 x 1/2” sheet metal screws.

B. INSTALL FLUE COVER PLATES over cleanout openings on left side of boiler as shown in Figure 19.

See Important Product Safety Information on Page 21 of this manual, regarding refractory ceramic ﬁber product warning.

1.Locate the cover plates, carriage bolts, nuts and washers in the boiler assembly carton(s).

2.Remove insulation from two (2) 3/8” diameter holes in ﬂue cover plates using a 3/8” drill bit. Rotate bit through insulation by hand.

3.Attach the carriage bolts to the top and bottom of the ﬂue openings with washers and hex nuts to provide a ﬁxed stud.

4.Install ﬂue cover plates over studs with insulation
