INSTALLATION INFORMATION

Do not attempt to heat through more than one doorway 

in any direction to adjoining rooms.
Always over-estimate the amount of heat required rather 

than under-estimate it. Always use the next size floor 

furnace above your actual heating requirements.
Seal all cracks around windows, doors, and attic access 

doors or significant heat loss will occur.

INSTALLATION REQUIREMENTS

Listed below are steps that are part of a floor furnace 

installation. You must see that each step is followed 

closely so that the floor furnace will provide maximum 

efficiency with safe operation.

YOU MUST:

  Locate the floor furnace in the best 

available space for safe and efficient 

operation.

2.

   Provide fresh air for combustion and 

venting.
