CALIBER DESIGNER DIRECT VENT
WARNING!
Always maintain minimum clearances or greater around the vent system. Do NOT pack air spaces with insula-
tion or other material.
Note:
Horizontal runs will require the use of one vent
support (or metal plumbers strap) for every 3 of vent.
CAUTION:
Provisions must be made to provide adequate combustion and ventilation air.
WARNING!
The horizontal run of vent must have a ¼ rise for every 1 of run towards the termination. Never allow the vent
to run downward. This could cause high temperatures and may present a fire hazard.
Note:
To ensure proper operation, verify that the venting
and termination are unobstructed.
