INDOOR HEATER
The design is also certified for indoor installation when equipped with the approved draft hood.
For Canada, indoor installation is restricted to an enclosure that is not occupied and does not directly
communicate with occupied area. Refer to the latest edition of CAN/CGA-B149.1 and B149.2 for specific
requirements.
Locate heater as close as practical to a chimney or gas vent. Heater must always be vented to the outside. See
Vent Piping Section for venting details. Minimum allowable space is shown on the nameplate.

screws removed in step 1 above.
