Can you use a Bryant/Carrier furnace during construction?
Yes, but there are a few requirements that need to be met so that you do not
void the warranty. Here are the things you need to be aware of:
1. It must comply with the First "Caution"
and "Location requirements" listed in the Installation Manual.
2. It must be permanently installed, all ducts
connected and sealed to the Furnace, TWO VENT PIPES CONNECTED AND TERMINATED
OUTSIDE THE STRUCTURE FOR CONDENSING FURNACES.
3. Both Furnace doors must be installed, all
penetrations sealed with grommets or appropriate means, intake/exhaust vents
completely sealed.
4. Furnace must be controlled by a Thermostatic
control (not "Hot Wired").
5. The Return Air temperature must be maintained
between 55-80 Degrees Fahrenheit with NO NIGHT SETBACK or intermittent
operation. (use of the furnace while the structure is under construction is
deemed "intermittent operation" per the installation instructions).
6. Temp rise must be within nameplate specifications.
7. A "good quality" filter must be used and
changed frequently. A "Hog Hair" style filter is not acceptable
filtration during construction.
8. Drywall dust and construction debris must be cleaned
from ALL HVAC system components and duct work after construction.
9. A new filter must be installed after construction
is complete.
10. Derate furnace and verity proper operating conditions on
initial start-up.
11. Ensure ALL DRYWALL DUST is cleaned from the
motors, circuit board, etc as soon as possible after construction.
We have seen too many premature failures due to improper use
of the furnaces during construction. Careful attention to these
requirements will save your company, your customer and your builder from
unnecessary nuisance failures and complaints.
Thanks for all you do to promote and support the
Bryant/Carrier brands!
