VENTING:
The MZ is designed for direct, concentric venting, although it
can be properly vented in other ways. The MZ is vented in 3
basic ways.
1. Horizontal Concentric
2. Vertical Concentric
3. Separated Exhaust & Inlet Air in 3" PVC
Horizontal vs. Vertical: The final terminal point of the vent
run determines which vent system should be used for the MZ.
THE SYSTEMS HAVE DIFFERENT DIMENSIONS AND
CANNOT BE MIXED. The horizontal system is less expensive
than the vertical system, foot for foot and fitting for fitting. For
vent runs in excess of 30 feet, contact MPI. All length of runs
must be accessible for inspection.
1. Horizontal Concentric:
The most economical venting location for the MZ is on or near
enough to an outside wall so that the vent box that fits the top
left-hand side of the MZ is within 38" of the final termination
point of the vent run. (see Fig. 1)
Use part number 9501 to provide all the necessary parts for
the above venting option.
The MZ’s horizontal vent system can run straight back from
the MZ or right, left, or over the top of the MZ at 90º increments
using the standard vent box mounting procedure. Vents must
slope back to the heating system. A minimum drop of 5/8th
inch per foot of horizontal run must be provided.
2. Vertical Concentric:
For vertical concentric venting, Monitor Products, Inc. kit
number #9505 is required. (see fig. 2).
Once the kit has been installed, the venting can be continued
by way of utilizing different lengths of concentric pipe, 90º
elbows, and 45º elbows. Part numbers & descriptions shown
in Table 1. Vents must slope back to the heating system. A
minimum drop of 5/8th inch per foot of horizontal run must be
provided.
