GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

Ceramic Blanket Installation		Figure 25	Ceramic Blanket Placement
Before installing the cast iron sections a ceramic blanket
gasket must be installed on the burner base. Locate the
roll of ceramic blanket and can of spray adhesive supplied
in the X1 box. Spray two heavy coats of adhesive on the
top of the burner base waiting for the adhesive to tack
up between coats, Figure 23.
Figure 23	Ceramic Blanket Adhesive Application

When the second coat of adhesive is tacky place a strip of ceramic blanket along each side of the base, Figure 24.

Figure 24Ceramic Blanket Placement

Lay strips of ceramic blanket along the front and back of the base making sure to overlap the ends as shown in Figure 25.

WARNING: The ceramic blanket must be overlapped as shown in Figure 25 to prevent the escape of flue gases. Failure to properly seal the cast iron sections to the boiler base can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

Cast Iron Section Assembly

WARNING: Never stand the cast iron sections up without adequate support. They may fall over resulting in property damage or severe personal injury!

Clean and inspect each section before assembly. Use a wire brush and a clean rag to remove rust and debris from the rope seal grooves and seal ports.

CAUTION: Never use any petroleum-based cleaners to clean the cast iron sections. Residue from the cleaner will result in the failure of the hydronic seals!

Using a tape measure, mark the midpoint of the burner base on the front and rear panels, Figures 26A and 26B.
