WARNING
L
!
EXPLOSION HAZARD!
NEVER USE AN OPEN FLAME TO DETECT GAS
LEAKS. EXPLOSIVE CONDITIONS MAY OCCUR. USE
A LEAK TEST SOLUTION OR OTHER APPROVED
METHODS FOR LEAK TESTING. FAILURE TO FOL-
LOW THIS WARNING COULD RESULT IN PROPERTY
DAMAGE, PERSONAL INJURY OR DEATH.
CAUTION
L !
To prevent shortening its service life, the Furnace
should NOT be used as a "Construction Heater"
during the finishing phases of construction until the
requirements listed in item 9, a-h of the safety sec-
tion of this publication have been met. Condensate
in the presence of chlorides and fluorides from paint,
varnish, stains, adhesives, cleaning compounds, and
cement create a corrosive condition which may cause
rapid deterioration of the heat exchanger
.
WARNING
L !
SAFETY HAZARD
DO NOT USE SEMI-RIGID
CONNECTORS (flexible GAS lines) within the Furnace
cabinet. Failure to follow this warning could result in
property damage, personal injury or death.
CAUTION
L !
Do NOT install the furnace in a corrosive or
contaminated atmosphere. Failure to follow this
caution could result in early equipment failure.
NOTE: The furnace must be installed level. The only
allowable variation would be slightly to the left and/
or forward in upflow installations or slightly toward
the front in horizontal installations. This is necessary
for proper condensate drainage.
WARNING
L !
SAFETY HAZARD
DO NOT INSTALL THE FURNACE DIRECTLY ON
CARPETING, TILE OR OTHER COMBUSTIBLE MATE-
RIAL OTHER THAN WOOD FLOORING. FOR VERTI-
CAL DOWNFLOW APPLICATIONS, SUBBASE (BAY-
BASE205) MUST BE USED BETWEEN THE FURNACE
AND COMBUSTIBLE FLOORING. WHEN THE DOWN-
FLOW FURNACE IS INSTALLED VERTICALLY WITH A
CASED COIL, A SUBBASE IS NOT REQUIRED. FAIL-
URE TO FOLLOW THE WARNING EXACTLY COULD
RESULT IN SERIOUS PERSONAL INJURY, PROPERTY
DAMAGE OR DEATH.
The following safety practices and precautions must be
