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 create a fire hazard.
Note:
Horizontal runs will require the use of one vent
support (or metal plumbers strap) for every 3 of vent.
CAUTION:
For vertically terminated installations, metal tape at
each vent joint will help prevent excess air infiltration
and improve flame appearance. All joints above the
storm collar should be taped and/or sealed with
silicone caulk to prevent water penetration.
