SUSPENSION
The duct furnace must be hung level from side to side and front to back, from four
suspension points provided at the top of the unit. Failure to do so will result in poor performance and/or
premature failure of the unit. Refer to Figure 5 for typical suspension arrangements. DO NOT mount duct
furnaces in series (one in front of another).
NOTICE: When mounting duct furnaces side by side, units must have opposite side gas connections
(determined by Digit #6 - Furnace Type in the unit number). Minimum safety clearances must also be
maintained; see Table 3. When service/accessibility clearances are greater than minimum safety clearances,
service/accessibility clearances take precedence. See “Accessibility” section under “Installation”.
MAKE CERTAIN THAT THE STRUCTURE TO WHICH THE
FURNACE IS TO BE MOUNTED IS CAPABLE OF SAFELY SUPPORTING ITS
WEIGHT. UNDER NO CIRCUMSTANCES MUST THE GAS LINES, VENTING
SYSTEM OR THE ELECTRICAL CONDUIT BE USED TO SUPPORT THE
HEATER OR ANY OTHER OBJECTS (I.E. LADDER, PERSON) LEAN
AGAINST THE HEATER GAS LINES, VENTING SYSTEM OR ELECTRICAL
CONDUIT FOR SUPPORT. FAILURE TO HEED THESE WARNINGS MAY
RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
MAKE CERTAIN THAT THE LIFTING
METHODS USED TO LIFT THE UNIT HEATER ARE
CAPABLE OF SUPPORTING THE WEIGHT OF THE
HEATER DURING INSTALLATION. FAILURE TO HEED
THIS WARNING MAY RESULT IN PROPERTY DAMAGE
OR PERSONAL INJURY.
