WARNING

Nipples must be driven in evenly and to the proper depth to assure tight joints. Most nipple leaks are caused by tilted or cocked nipples.

DO NOT use steel/iron head hammer to drive nipples without using a wood block. Nipple damage may result.

g.A special nipple setting gauge is provided for the nipples. Gauge nipple at 90° angles to insure that it is driven to the proper depth into the nipple opening (nipple port). Cut-out in gauge must rest on nipple, with legs of gauge touching finished face of section, when nipple is properly driven. See Figure 6.

Figure 6: Setting of Nipples

h.Remove a 96” length of fiberglass rope from the assembly carton. Starting with the area around the upper 7” nipple port, firmly press the rope into the groove, so that the adhesive holds it in place. (If more than 25 minutes have passed since the adhesive was applied, it may be necessary to reapply.) Continue to affix the rope to the groove in this fashion around the perimeter of the section. Make sure that the rope does not droop or hang outside of the groove. When the end of the groove is reached, cut off the excess rope. Push the length of excess rope into the groove at the top corner of the section face (opposite of the 7” nipple port.) Cut off and discard any remaining rope after groove is filled.

See Figure 7.

Figure 7: Affixing the Fiberglass Rope

NOTICE

The sections must be assembled according to the arrangement shown to ensure proper operation, proper assembly of canopy, jacket and alignment of piping and tankless heaters with jacket knockouts. Start with the back section and work towards the front.

i.From the “Section Arrangement” chart, select the next section according to the “Identification

Code” at the top of the chart. See Figure 8. Use a wire brush to clean the groove in the face of the next section. Then, using a cartridge of RTV 6500 or RTV 736 sealant in a caulking gun, fill the groove in this section with silastic sealant.

Touch-up any missed spots before draw-up. Touch-up after draw-up has no value.

WARNING

Sections must be drawn-up tight immediately after properly applying sealant for best results. Although sections may be joined within two

(2)hours of applying sealant, humidity and temperature affect cure time. If a “thick skin” has been formed on the sealant bead, remove and re-apply sealant.

Sealant must be properly applied toALL boiler joints. Failure to properly seal the boiler joints will result in combustion gas leaks through the joint. DO NOT operate boiler with combustion gas leaks.
