The primary air inlet holes allow the
proper amount of air to mix with the
gas. This provides a clean burning
flame. Keep these holes clear of dust,
dirt, lint, and pet hair. Clean these air
inlet holes prior to each heating season.
Blocked air holes will create soot. We
recommend that you clean the unit
every three months during operation
and have heater inspected yearly by a
