The entire combustion system must be sealed for this water
heater to function correctly. Replace any damaged parts.
Please see pages 86 & 90 showing the gaskets to inspect to
ensure they are combustion tight.
The entire exhaust flue system and combustion air supply must
be inspected at least annually for integrity of all joints and
gaskets.

FLAMMABLE VAPOURS AND LIQUIDS.
Water heater maintenance includes periodic tank flushing and
cleaning, and removal of lime scale. The unit should be
inspected and adjusted to maintain proper combustion. A
periodic inspection of the flue installation system should be
