5. Remove the plastic bag. Inspect the cones and
venturi tube to make sure these areas are clean.

and the venturi tube.
B. FILTER
A. During continued use:
- Remove filter and shake off dust.
- Do not squeeze or tap filter while filter is installed
on heater. Doing so will cause dust to be blown
into venturi tube or combustion cones.
B. After continued use or before building repopulation:
- Remove filter and shake off dust.
- Use compressed air or water (standard faucet
pressure) to clean it.
- Do not use high pressure water, air, or a washing
machine. Filter material damage may occur.
- If water is used, squeeze out excess water from
filter before installation.
- Let filter dry before lighting heater.
