E. VENTING
1. Vertical Termination
CAUTION:
Provisions shall be made to provide adequate
combustion and ventilation air.
WARNING - RISK OF FIRE!
Always maintain minimum clearances or greater
around the vent system. Do not pack air spaces with
insulation or other material.
WARNING!
The horizontal run of vent must have a 1/4 rise for
every 1 ft. of run towards the termination. Never allow
the vent to run downward. This could cause high
temperatures and may present a fire hazard.

2. Firestop Spacer/Vent Installation
Frame an opening and install a firestop spacer
whenever the vent penetrates a ceiling/floor area, as
shown in Figure 6. Frame the opening with the same
sized lumber as used in the ceiling floor joists. Unless
the flue is offset, the hole should be directly above the
appliance. DO NOT pack insulation around the vent.
Assemble vent sections with three screws per joint.
