7. 

on all sides.  It is recommended that a minimum of 29” of 

unobstructed area be provided in front of the access panels

The grilles on the outside of the units should be kept clear 

8. 

of obstructions to permit proper operation of the furnace 

vent system.

 The vent system is designed for proper operation under 

9. 

all weather conditions and for winds up to 40 mph.  Do not 

alter or extend the vent outlet. 

The furnace venting system is an integral, independent, 

10. 

complete, and tested part of the Comfort Pack unit.  It is not 

intended for field connection to any other venting system.  

Do not modify, alter or connect to the vent system in the 

unit.

and factory tested inside the Comfort Pack cabinet. The furnace 

includes an integral venting system that does not require any 

field modification or additions.  The control system includes a 

control board with cooling relay, combination gas valve, direct-

spark ignition electrode, flame sensor, blocked vent switch,
