Important:
Minimum safety clearances must also be 
maintained; see 
. When 
service/accessibility clearances are greater 
than minimum safety clearances, service/
accessibility clearances take precedence.

Conversion of access side
The tubular duct furnace is built and shipped as right side 
access—when looking in the direction of airflow, gas and 
flue connections, control cabinet access are on the right 
hand side and the combustion air inlet is on top. When 
looking in the direction of airflow, you will be facing the 
entering air side of the duct furnace. To convert the unit to 
left side access:
1.
Before suspending unit, flip the duct furnace 180° 
width-wise (not rotated) so the gas and flue 
connections are still on the entering air side of the duct 
furnace.
2. Remove the four (4) screws holding the combustion air 
inlet screen (now located on the bottom of the unit); the 
screen and gasket can be removed and set aside.
3. Remove the four (4) screws holding the block-off plate 
(now located on the top of the unit); the plate and the 
gasket can be removed and set aside.
4. Reinstall the block-off plate and its gasket on the 
bottom of the unit using the four (4) screws.
5. Reinstall the combustion air inlet screen and its gasket 
on the top of the unit using the four (4) screws.
It is not required to switch the combustion air inlet screen 
and block-off plate locations once the unit has been 
flipped. However, due to combustion noise, it is 
recommended to keep the air inlet screen on top for 
overhead installations.
Important:
If unit access side is converted, ensure 
accessibility clearance is taken into account 
for the new control cabinet end of the unit 
before suspension/installation.

WARNING
Heavy Object!
Make certain that the lifting methods used to lift the 
duct furnace are capable of supporting the weight of 
the heater during installation. See 
 for unit 
weights.
Ensure that all hardware used in the suspension of each 
duct furnace is more than adequate for the job.
Make certain that the structure to which the duct 
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 duct furnace. Do not allow objects (i.e. 
ladder) or people to lean against the gas lines, venting 
system, or electrical conduit for support.
Failure to follow these instructions could result in 
death, serious injury, and property damage.
NOTICE: 
Equipment Damage!
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 
 for typical suspension. DO NOT mount duct 
furnaces in series (one in front of another).
