Draft hood installation
1. Secure draft hood to flue collector hood with sheet metal
screws. See Figure 20, items 1 and 9, on page 26. Use boiler
cement to provide gas tight seal.
Failure to maintain gas‑tight seal can cause flue gas
spillage and carbon monoxide emissions, resulting
in severe personal injury or death.
Do not alter boiler draft hood or place any obstruction
or non-approved vent damper in breeching or vent
system. CSA certification will become void. Flue gas
spillage and carbon monoxide emissions will occur
causing severe personal injury or death.
