WARNING
DANGER
In freezing weather, check for snow accumulation
around the water heater vent and air intake terminals
where they pass through the outside wall. The open
ends of the terminals must be installed at least 12
inches (30 cm) above the highest anticipated snow-
fall to prevent blockage by snow.
WARNING
DANGER
Check that all openings and gaps in the outside
wall near and around where the vent and air
intake pipes pass through the exterior wall are
sealed to prevent infiltration of combustion
products into the building.
